Customized Refractory Brick High Alumina Shaped Brick Basic Information

Variety of different types of brick and variety of products, can make round, square, trapezoidal, with holes, concave-shaped and other models of different sizes of graphics, according to custom size and type of custom production and processing products. high alumina brick is not less than 1580 ℃ of a class of inorganic non-metallic materials. Refractoriness refers to the refractory material in the absence of load conditions, the role of resistance to high temperature without softening melt down the Celsius temperature. But only to the definition of refractoriness can not fully describe the refractory, and 1580 ℃ is not absolute. Now defined as the physical and chemical properties allow its use in high temperature environment known as the refractory material magnesia carbon brick . Refractories are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount in the metallurgical industry, the total output of 50% to 60%. Refractory brick is made of bauxite China refractory brick . Refractory materials made of refractory clay or other refractory materials. Light yellow or brown. Mainly used in puzzle smelting furnace, the ability of 1580 ℃ -1770 ℃ high temperature. Also known as high temperature refractory bricks. Refractory materials with a certain shape and size. According to the preparation process can be divided into prefabricated brick sintered bricks fused brick (brick), refractory used for high temperature furnace ; according to the shape and size can be divided into standard brick, ordinary brick, brick and other special. It can be used as high-temperature building materials and structural materials for construction kilns and various thermal equipments, and can withstand various physical and chemical changes and mechanical action at high temperature.

refractory manufacturers  shaped brick in accordance with its drawings of the complexity of complex graphics processing, single weight, size and use of its parts. To select its production mode of production, in accordance with the production mode of production can be divided into: unburned refractory brick prefabricated parts and sintered refractory shaped brick two kinds of sintered refractory shaped bricks suitable for volume and weight in the small and medium sized, and unburned refractory bricks Prefabricated parts will be more convenient for the shape and weight do not have too many requirements can be arbitrarily processed. In accordance with the choice of materials can be divided into a variety of materials: clay, high alumina, corundum, silicon carbide mullite and so on. The shape of the sintered refractory bricks may be circular, square, rectangular, perforated, embossed, or mated.

Industrial furnace furnace structure and furnace building materials

Design or improvement of the furnace, should be based on production process requirements, try to use new energy-saving stoves. Select the appropriate furnace structure, improve the degree of mechanization and energy efficiency. At present, commonly used energy-saving measures are: industrial furnace refractory manufacturer (1) the use of circular hearth instead of box-shaped furnace, the furnace can enhance the effect of uniform heat transfer to the workpiece to reduce the heat dissipation of the furnace wall so that the formation of a heat exchange furnace system, heating elements, lining and the workpiece 3 between the heat exchange. Through the use of reasonable furnace space

And without increasing the volume of the furnace space under the premise of increasing the furnace wall area  refractory manufacturers to increase the heat exchange area of the way to improve the heat exchange furnace to improve thermal efficiency. (2) installed in the furnace fan, to enhance the convection heat transfer. In particular, small-scale heating furnace, high-speed air flow can be stalled at the surface of the workpiece hinder the heat transfer and interface reaction furnace bottom boundary layer, to shorten the heating time and speed up the role of improving the workpiece temperature. Industrial furnaces

Refractory materials (3) furnace seal, including the furnace of the lead-out components, furnace shell, door and so on the seal. Furnace sealing is not strict, will cause everywhere to run the fire, fire, resulting in a large number of waste of energy, equipment burned, harsh environment and so on, so the furnace seal directly affect the workpiece

Quality and energy consumption, while sealing the furnace is the key to climate control. The emergence of refractory fiber products, in order to solve the furnace seal to create the conditions to achieve a soft seal. (4) the use of refractory castable casting the overall furnace with high strength, integrity, air tightness, long life and so on. (5) the use of new furnace materials, optimize the lining structure. Lining in ensuring the structural strength of the furnace and heat resistance under the premise of  insulation clay brick should be increased capacity and reduce the heat savings. Simply relying on increasing the thickness of the lining to reduce the furnace wall temperature will not only increase the furnace heat storage

And cost, and correspondingly reduce the effective utilization of the bottom area. The use of refractory fiber, rock wool as insulation layer, with light brick as the lining of the furnace to reduce the heat storage loss of the furnace to enhance the insulating castable refractory of the stove to reduce the heat loss of the furnace wall. industry

Furnace refractories (6) in the furnace wall coated with high temperature and high radiation coatings, heat radiation to strengthen the furnace to help the full use of heat, the energy saving effect of 3% to 5%, is the recent more advanced energy-saving methods. Industrial furnace refractory cotton insulation characteristics: 1. Excellent chemical stability and thermal stability 2. Low thermal conductivity, low heat capacity 3. In the module on the back of the various forms of the anchor, so that the module can be used to install the soldier-style arrangement can also be parquet floor arrangement. Refractories for industrial furnaces 4. Folding blanket in the lifting of binding in different directions will squeeze each other, no gap 5. Elastic fiber blankets can resist mechanical forces 6. The elasticity of the fiber blanket can compensate for the deformation of the shell, so that no gap between the components 7. Due to its light weight, there is little heat absorption as a thermal insulation material 8. Low thermal conductivity to bring high energy efficiency 9. Has the ability to resist any thermal shock 10. Lining without drying and maintenance, so after installation can be put into use immediately 11. The anchoring system is away from the hot face of the assembly so that the metal anchor is at a relatively low temperature.
