Following the clay and high alumina brick, tundish insulation board, tundish coating, Dry vibration mix is the fourth working lining materials for tundish. Following compare shows why dry vibration mix could replace the insulation board successfully.    Insulation board, which is mainly used in cold tundish (one without baking before being used), it devotes much for us in energy saving and heat insulation. But, due to its fatal disadvantage, it is being eliminated quickly. 1. Bonded with many agent, insulation board add silica and hydrogen under high temperature in steel liquid, reduce its purity, produce harmful gas to hurt workers health. VS: Dry vibration mix is bonded without carbon, produce no sharp aroma, and greatly reduce avoid the pollution for steel liquid and environment. 2. Short using life (for common steel, only 8 Hrs, For Mn-alloy steel, only 4hrs). VS: dry vibration mix usual using life: min 24 hrs, when worked with the fast exchange nozzle, it could reach average using life 45hrs. 3. Easy to be broken during transportation, once one piece is broken, the whole set will can not be work. VS: dry vibration is premixed and packaged in waterproof jumbo, applicable for ship, truck, train, air, etc long way transportation. 4. Low corrosion resistance, easy to make tundish become leakage. VS: dry vibration mix is made by ramming, dense and stable, after sintering, form a protect layer with tundish backing layer, could improve tundish using life and reduce spare tundish number.    Therefore, should you want to improve your tundish life, please do not hesitate to try Changxing Refractory dry vibration mix, 24 hrs using life is waiting for you.

Refractory Materials for EAF

EAF (Electric Arc Furnace) is mainly used for steelmaking with steel scrap as the main raw material. According to power types, EAF can be mainly divided into DC EAF and AC.    Same as other high temperature induction furnaces, refractory materials are widely used for EAF. EAF refractory materials are mainly as follows. 1. DC EAF Magnesia, magnesium carbon, magnesium aluminum and magnesium chrome refractories are widely used in DC EAF. Non-carbon alkaline bricks are widely used in Europe; while in Japan, thermal shock resistance is thought as a great question, so they prefer using magnesium carbon bricks with high carbon content. In order to improve thermal shock resistance and corrosion resistance of metallurgical equipment, magnesia spinel materials and magnesia-chrome brick are widely used in Europe. 2. AC EAF For small AC EAF, asphalt brick, magnesium carbon brick, magnesia gun mix are widely used at furnace wall. For ultra-high power electric AC EAF, high-quality magnesium carbon brick would be used for furnace wall, while for slag line, higher performance high-magnesium carbon brick would be needed. Out of magnesia carbon bricks, magnesia gun mix would be used to repair furnace wall during working.    We Changxing Refractory Material Co., LTD are a professional manufacturer and supplier of refractory materials for about 40 years. Our high quality magnesia carbon bricks are selling well in many countries say South Africa, Bangladesh, Indonesia, Malaysia, etc. Shall any interests, welcome to contact us! Our team will do the best to be your reliable partner!
