MgO-C Brick
MgO-C Brick
The magnesia carbon brick for the working layer of electric arc furnaces is made of large crystalline high-purity fused magnesia and high-purity flake graphite as the main raw materials, combined with resin and adding compound antioxidants, and formed by high pressure.
The MgO-C brick we provide features low porosity, high-temperature strength, erosion resistance, and spalling resistance, etc. Customers can choose different brands of magnesium carbon brick according to the smelting conditions at the slag line, hot spot parts, and steel outlet, respectively.
