How much is one refractory brick ?

　There are always a lot of users ask about the price of refractory bricks, some users will ask how much is refractory brick per ton?How much is one refractory brick? This question is too vague, because the factor that affects the price of refractory brick is too much, such as material , index, shape and size of refractory brick.Some refractory brick cost 3-5 yuan per piece, some refractory brick cost more than 10 yuan per piece, some refractory brick cost several hundred yuan a piece, and also have precast refractory brick, the price is also different.

　　Among the common types of refractory bricks, we have introduced a lot of refractory bricks.Such as clay refractory brick, high alumina refractory brick, mullite refractory brick, corundum refractory brick, magnesia brick, carbon brick and so on.

　　1. Different materials of refractory bricks, the raw materials used in the production and the formula are also different, so in the procurement of refractory bricks, it is necessary to understand what materials used for the refractory brick, is it high aluminum or clay, for refractory with different materials, the prices are also different. For example, the price of clay refractory brick and high alumina refractory brick are different.

　　2. There are also differences in refractory bricks used in different environments.For example, there are dozens of kinds of refractory bricks for blast furnace, with carbon brick in the bottom of blast furnace and ceramic cup of blast furnace can be used as compound brown corundum brick, corundum mullite brick, and microporous corundum brick can be used.There are so many kinds of refractory bricks that can be used in only the bottom of the blast furnace, and there are many kinds of refractory bricks used in the furnace body, the furnace wall and the throat of the furnace. Therefore, it is necessary to understand the kiln environment that the refractory bricks are used for.

　　3. the same material refractory bricks used in different kilns are different, such as high aluminum brick for blast furnace and hot air stove, although the same is high aluminum brick, but different kiln environment, the requirements for refractory bricks are also different.

　　4. Due to the refractory brick as a kiln lining is needed, the building up of complex industrial kiln, so for environment when purchasing refractory brick type, some still need to design production mold and processing production of refractory brick.

　　5. The number of refractory brick, such as purchasing 1 ton and purchase 100 tons of refractory brick, refractory brick also have certain difference, the price of the average output, the greater the refractory brick manufacturer in refractory raw materials procurement, the price is more favorable, the production of refractory brick, the price also is more favorable.

　　Therefore, when you want to know how much is the refractory brick, it is necessary for the refractory brick manufacturers to provide detailed specifications, the environment and the number of refractory bricks. Only in this way can we understand the real price of the bricks. If you want to know how much a refractory brick is, it can be calculated by the density of bricks and the quantity of bricks.

　　The above is the basic introduction of how much is one piece of refractory brick. To know more about the price information of refractory brick, please contact REWELL, and we will provide you with the most suitable refractory brick quotation according to the information you provide.

How does decide the price of refractory brick

　　For the price of refractory bricks, we have said many times, when users choose fire bricks, they will let the refractory brick manufacturers provide a fire brick price. Rewell as a refractory brick manufacturer, how to determine the price of refractory brick? I'll tell you.

　　When Rewell sells refractory brick, The first consideration is whether we can make the refractory bricks for the users, what kind of material, what kind of indicators, which parts of the kiln used in the refractory bricks and so on, as a result, there are so many factors affecting the price of refractory bricks, like the common refractory brick materials such as clay, high aluminum, mullite, corundum, magnesium carbon and so on; different refractory materials are suitable for different kiln environments, and can be made into acid resistant, alkali resistant, corrosive resistant and wearable ones; the bulk density of refractory bricks is also very important,users will ask for the porosity of refractory bricks, lightweight refractory bricks needed or compact refractory bricks needed and so on.

　　To sum up, there are many factors to be considered when determining the price of refractory brick, there are several aspects as follows:

　　1) Material of the refractory brick, such as high alumina refractory bricks, refer to alumina content, such as magnesia carbon bricks, which refer to magnesium oxide and carbon content.

　　2) The chemical properties of refractory bricks, that is, the quantity of content.

　　3) Physical properties of refractory bricks, such as compressive strength, bulk density, apparent porosity, etc.

　　4) Refractory bricks are suitable for furnaces, such as high alumina bricks for blast furnaces and high alumina bricks for hot blast stoves.

　　In addition to the above four points, we can not determine the price of refractory brick by 100%. We also need to know the dimensions of refractory bricks, and the refractory bricks are of standard size and special size. For example, the size of the standard brick is 230*114*65mm, and the size of the standard wedge brick is 230*114*65/55mm. There is also a refractory brick that needs to be processed through the drawings, it is called the special-shaped refractory brick, with different kinds of arc, grooves, grooves, and the more complex bricks of the shape, the more complicated the process is.

　　When refractory brick manufacturers sell refractory bricks, they are sold according to how much is a ton of refractory bricks, such as three grade standard high alumina brick, one ton of three grade standard high alumina brick is 1000 yuan; however, some users do not have a large quantity of purchases,sometimes only require hundreds of pieces, that's need to calculate the price for a single piece.We also take the three grade standard high alumina brick as an example. First we know that the bulk density of the three grade high aluminum standard brick is 2.15g/cm3, the alumina content is 60%, the single block weight is 3.7kg; the weight of a ton divided by a single weight can calculate how many pieces per ton, and the price of refractory brick is divided by the total pieces, that is, the price of one piece refractory brick. This is the calculation method of the price of whole ton refractory brick and the price of single brick refractory brick.

　　If users purchase large amount refractory brick, then it will talk about the issue of value-added tax, which is also one aspect of calculating the price of refractory brick.Except the tax , as well as transportation, refractory brick making, how to transport, which port, which city, use land transport or sea transport, and so on, different destinations, different modes of transportation, and the cost of refractory bricks are also different.

　　To sum up, the factors that affect the price of refractory brick: the refractory brick EXW price, tax and freight, therefore, purchase refractory bricks must be choose refractory brick manufacturers, the experienced brick making personnel, powerful refractory brick burning kiln, and the high quality and quantity of refractory bricks for the users.

REWELL refractory | The process of producing and pressing slag dart

What are the sizes of the refractory bricks ?

　　When we buy refractory brick, the first focus is refractory brick index, price and size.But when refractory bricks masonry the lining of kiln.It is necessary to use different sizes to make the lining of the kiln tightly masonry.To better resistance to the erosion of kiln gas and slag.Today we will understand what are the sizes of refractory bricks.So that it is convenient for you to reference when you purchase.

　　To understand the size of refractory bricks, first of all, we need to know what is the shape of refractory bricks.Generally, the refractory brick is divided into the following shape:

　　1.Standard refractory brick:That is the universal straight refractory brick.

　　2.Shaped refractory brick:Generally refers to cuboid refractory brick, and the thickness of both ends is different.

　　3.Special-shaped refractory brick:Generally refers to all kinds of refractory bricks shape except cuboid.

　　Next we will elaborate on the size of the above three types of refractory bricks:

　　1.The standard refractory brick size is divided into:

　　Straight refractory brick,it size is 230mm×114mm×65mm、300mm×150mm×75mm

　　Three-quarter long brick,it size is 172 mm×114mm×65mm、172mm×150mm×75mm

　　Sesquialter length brick,it size is 345 mm×114mm×65mm、345mm×150mm×75mm

　　Double length brick,it size is 460 mm×114mm×65mm、460mm×150mm×75mm

　　Sesquialter width brick,it size is 230mm×172mm×65mm、300mm×172mm×75mm

　　Half thick thin brick,it size is 230mm×172mm×33mm、300mm×172mm×38mm

　　Double width brick,it size is 230mm×230mm×65mm、300mm×230mm×75mm

　　Extended brick,it size is the length and width are all over the size of the straight brick, the thickness is 65mm and 75mm.

　　2.The shaped refractory bricks are also general wedge bricks.The size is divided into:Thick wedge brick,Side - thick wedge brick,Vertical thick wedge brick,Sesquialter width vertical thick wedge brick,Double width vertical thick wedge brick and vertical width wedge brick

　　3.The special-shaped refractory brick size is not certain:Such as arch brick, semi-circular brick, anchored brick and so on.

　　The above is the introduction of the size of the refractory bricks.When firebrick is purchased,the size of refractory brick,whether is the standard brick or not,whether need to make mold ,all these is affect the price of refractory brick,so it need inform of refractory manufacturer ,So the size of refractory bricks is also very important.

What is the difference between refractory materials and refractory raw materials?

　　In the refractory industry, there are refractory materials and refractory raw materials, and some users are not very clear about these two things, so that they can not find the correct refractory materials and material information when they need refractory products. Today, we simply introduce the difference between fire-resistant materials and refractory raw materials, making users more convenient and faster in finding information and buying.

　　What is the difference between refractories and refractory raw materials? We will explain from the following aspects:

　　1.First, from the name of the refractory, the English name of the refractories is "refractories" or "refractory material". The refractory raw material is English "refractory raw material".

　　2.Secondly, the definition is: refractory material is defined as inorganic nonmetallic material and the refractory is not less than 1580 C, and has resistance to high temperature change and slag erosion and can withstand high temperature load. The sintering or non sintering, casting, and fiber made of natural raw materials, synthetic raw materials, waste residue, regenerated material and so on are made from different processes. The general name of the unshaped products. Refractory materials are defined as raw materials for the manufacture of refractory materials with high melting point or high refractoriness, such as single, oxide, non oxide or compound compounds, including natural mineral raw materials, industrial raw materials or synthetic raw materials.

　　3. Again from the shape: refractories are divided into shaped and unshaped refractory. Refractory materials are generally powdery or with a certain particle size. Used refractory bricks are a special refractory material.

　　4. From common products, refractories have refractory bricks, refractory castables, refractory mud, heat insulating refractory fiber materials, prefabricated parts, etc. fire-resistant raw materials include refractory clay, bauxite, silica, pyrophyllite, industrial alumina, fused corundum, synthetic mullite, synthetic magnesia, refractory hollow ball and fire resistance, waste bricks and so on.

　　5. From the relationship between refractories and refractory raw materials, refractories contain refractory raw materials, as refractories are made of refractory materials with a series of processes combined with other raw materials.

　　From the above five aspects, we can see the difference between refractories and refractory materials, and refractory raw materials are the basis for making refractory products. Only when we know the difference between them can we find the product information more accurately when looking for refractory materials or refractory raw materials.

　　Rewell is a professional refractory company. In the production of refractories, we need to buy high quality refractory raw materials from the refractory raw materials factory and do the basic work of the quality assurance of refractory materials. Only if we control from the source so we can produce the refractory materials that meet the needs of users. Therefore, Rewell refractories has long-term partner with good raw refractory material manufacturer.

What is the difference between clay bricks and high alumina bricks

　　Clay bricks and high alumina bricks are common refractory bricks. As the industry insiders, most of the clay bricks and high alumina bricks are distinguished from the appearance, but this is only one-sided. So, what is the difference between clay brick and high alumina brick? Today we will come to know about it, and provide reference for purchasing clay brick or high alumina brick.

　　I、 Clay brick

　　1.Definition of clay bricks

　　Clay brick is an aluminum silicate refractory product with Al2O3 content of about 30%-48%. It is made of refractory clay or kaolin and clay clinker combined with clay, formed by semi dry or plastic molding and baking at 1250-1420℃.The finished clay bricks are not very dense in appearance, the color is pale yellow and brown, sometimes even dark brown, and sometimes there are brown and black mottled, dark brown indicates that the iron oxide content is high, light yellow and yellow are normal color. The refractories of clay bricks are generally at 1580 -1750 ℃and the softening temperature at 1250 C -1450℃.

　　2. Characteristics of clay brick:

　　(1) strong plasticity.

　　(2) good stability of thermal shock.

　　(3) good volume stability of high temperature .

　　(4) strong ability to resist acid slag.

　　3.Application of clay bricks: clay bricks are used to masonry heating furnace and heat treatment furnace, flue, flat furnace storage lattice brick and bottom of regenerator wall, inner lining of air pipe and gas pipeline, dust remover of iron smelting furnace, lining of flue gas, dry belt of rotary kiln and preheating belt, and it also the general refractory material apply to boiler, lime kiln and glass kiln and ceramic kiln .

　　5.Clay brick price

　　Clay brick production process is simple, the scope of application is wide, its price is also more economical, the price of clay brick is about 1000 RMB, the concrete clay brick price can contact the clay brick manufacturer.

　　II、 high alumina brick

　　III、 Definition of high alumina brick

　　High alumina brick is an aluminum or alumina product with more than 48% Al2O3 content. It is made from natural bauxite as raw material, including bauxite, Bobby stone, kaolinite and so on. Adding soft or semi soft clay as binder in high alumina clinker and mixing, then forming, drying, and finally burning. The firing of high alumina brick is more compact and the color is more white or yellowed. The refractoriness of high alumina brick is about 1770℃, and the softening temperature of load is 1420 -1550℃.

　　2.Characteristics of high alumina brick

　　(1) high softening temperature of load

　　(2) good thermal shock resistance.

　　(3) strong corrosion resistance, alkali resistance and slag resistance.

　　3.Application of high alumina brick

　　Masonry blast furnaces, hot blast stoves, ladles, lining of rotary kilns and other metallurgical furnaces, high alumina bricks can also be used as lattice bricks on hot blast stoves, stacking regenerators.

　　5.High alumina brick price

　　High alumina brick is the commonly used kiln lining brick, high aluminum brick with big difference because of the aluminum content, index, performance and so on are different, the ordinary high aluminum brick price is generally about 4000 RMB, the concrete high aluminum brick price please contact the high alumina brick manufacturer.

　　The above is the introduction of clay brick and high alumina brick from the definition, appearance, characteristics, uses, indicators, prices and so on.

　　(1) the Al2O3 content of clay brick is low, and the Al2O3 content of high alumina brick is high. Although both contain Al2O3, their properties and uses are different.

　　(2) in appearance, clay brick and high alumina brick are also very different, so generally distinguish clay brick and high alumina brick are using the surface view method.

　　(3) the refractories of clay bricks are generally at 1580 -1750℃, and the softening temperature of the load is 1250 C -1450℃. The refractoriness of high alumina brick is about 1770℃, and the softening temperature of load is 1420 -1550℃. The refractories and load softening temperatures of clay bricks and high alumina bricks are all close, but the environment used by them is differ somewhat.

　　(4) from the characteristic point of view, it is the national standard refractory brick, the clay brick and the high alumina brick have different properties, and the slag corrosion resistance is good, especially for the acid slag, and the thermal shock stability is also good.

　　(5) from the index point of view, the compressive strength of high alumina brick is higher than that of clay brick, and the impact resistance of high alumina brick is better than that of clay brick.

　　(6) finally, we distinguish from the price of the refractory brick, the high alumina brick is higher than the clay brick because of the high Al2O3 content, so the clay brick can be satisfied with the kiln with high alumina brick.

　　This is the difference between the clay brick and the high alumina brick. When you choose and buy, you must know what parts of the kiln are applicable to the kiln, and what effect can be achieved after use,then ask the staff of firebrick manufacturer to know the index of the firebrick, and then choose the products you want, and hope the above opinion will help to you. It is helpful to choose clay firebrick or high alumina firebrick. Welcome customers to rewell to visit and exchange with.

What's the price of the corundum brick?

　Is the corundum brick expensive? Corundum brick is a kind of high-grade firebrick, and the price of corundum brick is slightly higher than other refractory bricks. How much is the price of corundum bricks? Next, I will elaborate on the price of corundum bricks combined with practice.

　　The firebrick with AL2O3 greater than 90% is corundum brick. Corundum brick has good volume stability, strong corrosion resistance to acid and alkali slag and good thermal shock Stability.

　　Classification of corundum brick

　　1. The corundum brick can be divided into four parts according to the process

　　1.1 Sintered corundum brick: The main raw material of the sintered corundum refractory brick is corundum. Then add the refractory powder and binder and burned at 1600-1800 C. According to the dispersing degree of the refractory raw material and the application and performance requirement of the corundum brick, the different burnt system is adopted.

　　1.2 Sintered corundum brick : sintered corundum as main raw material,then made to mud material by adding the corundum powder. Fire bricks made by molding, drying and sintering.

　　1.3 Fused corundum brick: The main raw material of the fused corundum firebrick is corundum. Unlike the sintered corundum refractory brick,its production process is fused by electric melting in the electric furnace.

　　1.4 Fused corundum brick: fused corundum clinker as the refractory aggregate, fused corundum powder or sintered corundum powder as matrix,then it was made after preparation,then it was made by molding and dried and sintered.

　　2. According to the material of the corundum brick, it can be divided into:

　　2.1 Brown corundum: The main raw materials of brown corundum brick are bauxite and charred coal(anthracite). It is made in an electric arc furnace by 2000 degrees of high temperature smelting.

　　2.2 White corundum: White corundum brick is made of alumina powder and melted by high temperature.

　　2.3 High alumina corundum: The main raw material of high alumina corundum brick is high quality bauxite, which is smelted by special technology in high temperature electric furnace at 2500 degree.

　　2.4 Zircon corundum: High alumina corundum brick is made of high quality bauxite. It is produced by special technology in a high temperature electric furnace at 2500 degree.

　　2.5 Monocrystalline fused alumina: Monocrystalline fused Al2O3 abradant(Also called 32A) ：The main raw material of monocrystalline fused alumina is bauxite. Then add appropriate amount of sulphide and melt by high temperature.

　　2.6 Microcrystalline fused corundum: The main raw material of microcrystalline fused corundum is bauxite, which is obtained by smelting at high temperature and crystallizing by quench.

　　Through the above introduction of corundum bricks, you must know the type of corundum bricks. We know that the material is different, the performance is also different, the price also has the difference when we purchasing corundum brick or other refractory brick.

　　What is the price of the corundum brick?Combined with the market actual situation,the price of the corundum brick is about 4500 -16000 yuan per ton. Why is the price interval so different,its because the different materials of corundum bricks,so the price is different. If you need to know the price of corundum bricks, please provide corundum bricks’ physical and chemical indicators, application, size or drawings and other information. According to your information, we will make the most accurate price quotation for corundum bricks for you.
