MgO-C bricks

MgO-C bricksMgO-C bricks are made from dead burnt magnesia (or electro fused magnesia), carbon material (mainly perfectly crystallized graphite) and resin binder, by proportioning and pressingApplication 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 spaling 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 od these properties of MgO-C bricks make them the ideal material for furnace lining, which possesses good thermal shock resistance, corrosion resistance and spalling resistaance.MgO-C bricks h
