Product Description
Magnesia Carbon Bricks
Magnesia Carbon Brick is a kind of quality refractory materials. Their main components are magnesium oxide and carbon, of which magnesium oxide content is 60~90% and carbon content is 10~40%. This kind material is made of high purity magnesia particle, carbon material, tar, pitch or resin as the raw materials through high temperature baking. Magnesia Carbon Refractory Bricks have properties of slag corrosion resistance, thermal shock resistance, thermal conductivity and etc.

Application
Magnesia Carbon Brick for Steel-making Industry
Due to excellent characteristics, magnesia carbon fire brick is very suitable for iron and steel smelting. Carbon materials are not easily corroded by slag and molten steel. Besides, magnesia has high refractoriness, strong slag resistance and creep resistance and can well deal with slag lines and steel ports that are severely damaged by corrosion. Customers often use this brick in converters of steelmaking furnaces, electric arc furnaces, inner linings, ladle slag lines, refining furnaces and other parts.
Magnesia Carbon Brick for Other High Temperature Industries
In addition to the steel industry, magnesium carbon bricks have wide applications in other high-temperature kilns that are severely eroded by alkaline substances. Such as basic oxygen furnace lining, metallurgical furnace, cement furnace, working lining of ceramic furnace and other parts.
