Aluminum-magnesia-carbon brick (alumina-magnesia-carbon brick) refers to refractory products made of super high-grade alumina or corundum sand, magnesia and flake graphite as the main raw materials. Al-magnesia-carbon bricks are fire-lined products made of special high-grade bauxite or corundum sand, magnesia and flake graphite as main raw materials. Its characteristic is that in addition to the advantages of high corrosion resistance and resistance to peeling due to carbon content at high temperatures, it also has the advantages of showing high residual linear expansion rate due to heat generated spinel during use, thus becoming a newly developed high-quality Lining bricks.
