CARBON CONTAINING BRICK
Carbon containing Refractories
Mgo-c bricks are made from dead burnt magnesia (or electro-fused magnesia), carbon material (mainly perfectly crystallized graphite) and resin binder, by proportioning and pressing. Application under high temperature of the bricks can form carbon skeleton bonding. Because Mgo and C do not have mutual solution, good refractory properties of original components are kept. In addition carbon has good thermal conductivity and low thermal expansion coefficient and elastic coefficient and can prevent high temperature spalling and slag penetration effectively. Thus structural spalling does not occur. The fatal weakness of deteriorated structural spalling caused by slag penetration into magnesia refractories can be changed greatly. Carbon is not wetted by slag and has good resistance to wear. All of these properties of Mgo-C bricks make then the ideal material for furnace lining, which possesses good thermal shock resistance, corrosion resistance and spalling resistance. Mgo-c bricks have wide applications and can be used in key lcocations of thermal processing equipment such as steelmakig converter, electric are furnace, ladle, secondary steelmaking furnace and so on. Al-Mgo-C bricks made from high quality calcined bauxite, electro fused corundum and electro fused magnesia possess low thermal conductivity coefficeient and appropriate residual espansion and are good material for ladleslag line, ladle lower wall, bottom and free zone
