KERUI Magnesia Carbon Bricks Uses

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. Therefore, Kerui magnesia carbon refractory brick is suitable for all kinds of high temperature furnaces and kilns. Many customers choose the magnesium carbon brick for their business.
