Magnesia Carbon Brick

Magnesia carbon brick is made of high-purity magnesia powder, carbon materials (including graphite) and tar pitch or resin after batching, hot mixing and molding and being roasted at about 300 ℃ or above 1000 ℃.

As a composite refractory, magnesia carbon brick effectively makes use of the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, and compensates for the poor spalling resistance of magnesia. It has the characteristics of slag erosion resistance, slag permeability, thermal shock stability and thermal conductivity.

It is mainly used for the lining and tapping port of steelmaking oxidation converter, the hot spot of high-power electric furnace wall, refining furnace lining, the slag line of steel barrel, etc.
