Magnesia Carbon Brick, High Purity Raw Material, Corrosion & Erosion Resist

MgO - C bricks are made through thermal mixing, high - temperature forming and hot
treatment of fused magnesite and graphite, as the main raw materials, bonded by
phenolic resin by adding a certain quantity of antioxidants.
In order to improve the oxidation resistance and temperature of the bricks, some
antioxidants, like metals, carbide, etc. are normally added and low thermal
expansion coefficient. Carbon has very good thermal conductivity and low thermal
expansion coefficient. The wetting angle between carbon and molten slag is big
which can effectively prevent slag from penetration. So thermal spalling may not
happen easily. The bricks are widely used for metallurgical industry furnaces, like
steel - making converters, electric furnaces, ladle refining furnaces, etc.MgO - C
