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.
Properties of Magnesia Alumina Carbon Bricks
Lower apparent porosity and low heat conductivity,
Good thermal shock resistance,
High strength good corrosion resistance,
Good erosion resistance,high slag resistance,
Excellent anti-oxidation and anti-stripping ability.
Advantages of Magnesia Alumina Carbon Bricks
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.
Manufacturing Process of Magnesia Alumina Carbon Bricks
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.

Application of Magnesia Alumina Carbon Bricks
Magnesium alumina carbon fire brick are widely used in ladle in continuous casting and in a certain extent alleviated the low continuous casting ladle life contradiction. Also magnesium alumina carbon firebrick can be used in the following place:
1.Converters, EAF,refining furnaces,
2.Slag line and metal line for ladle,
3.Electric arc furnace working layer,
4.Converter furnace working layer,
5.Super electric furnace ,ladle lining and refining outside the furnace.
