Description of Alumina Magnesia Carbon Bricks With 55%-75% Alumina Content Are Used in Electric Arc Furnaces And Converters

The magnesia-carbon bricks produced by our company use high-purity, high-density fused magnesia, large crystal magnesia, and high-purity flake graphite as the main raw materials, add an appropriate amount of antioxidants, and use phenolic resin as a binder. to make. The series of alumina-magnesia-carbon bricks produced are mainly made of corundum, super-high alumina bauxite, fused magnesia and high-purity flake graphite, with phenolic resin as a binder, and are produced by high-pressure forming and low-temperature baking processes. It has good thermal strength and slag resistance, and is suitable for the wall and bottom of small and medium ladles.
