Unburned magnesia calcium carbon brick
MgCaO-unburn
Unburned magnesia calcium carbon bricks refer to refractory products made of dolomite sand, magnesia and flake graphite as the main raw materials. Its main feature is that the corrosion resistance of low alkalinity and low iron slag is better than magnesia carbon brick. Generally, it contains 60% to 70% of MgO, 10% to 20% of CaO, and about 15% of C. MgO-CaO-C bricks have excellent slag corrosion resistance, slag permeability, thermal shock resistance and thermal conductivity, but special attention should be paid to waterproofing measures. There will be a large number of applications in steelmaking converters, electric furnaces, out-of-furnace refining furnaces, and ladle. mgcao brick
