Magnesite alumina carbon brick is a kind of refractory bricks which are made of special grade high alumina bauxite or emery, magnesia and flaky graphite as the main material. magnesia alumina carbon firebrick has the characteristics of high corrosion resistance, high refractoriness and good mechanical behavior under high temperature, etc. Magnesia alumina carbon refractory brick is widely used in rigorous molten steel ladle liner. And also the magnesia alumina carbon firebrick is used in the molten bath and ladle bottom of continuous casting large tundish and external furnace refining package is increasing.
Magnesia alumina carbon fire brick have anti erosion, anti stripping, antioxidant and notsticky residue etc.. magnesium alumina carbon fire brick has widely used in ladle in continuous casting and in a certain extent alleviated the low continuous casting ladle life contradiction.
Magnesia alumina carbon block is the refractory raw material with special grade bauxite
magnesite or corundum and flake graphite, which is characterized in high temperature with high carbon with high corrosion resistance and anti stripping advantages, also has
the heat generated by the use of spinel and showed residual line of high expansion ratio
advantages, has become the new development of high quality lining brick.
