Aluminum Silicon Carbide Carbon Bricks (Al2O3-SiC-C bricks) (ASC bricks for short) are mainly made of dense fused corundum, fused white corundum, brown corundum, tabular corundum, silicon carbide and graphite. Aluminum Silicon Carbide Carbon Bricks (Al2O3-SiC-C bricks) have excellent performance, which is reflected in the resistance to chemical erosion of molten iron and slag and the erosion of molten iron and slag.
Al2O3-SiC-C bricks are used for the lining of molten iron pretreatment equipment such as torpedo-type mixing iron cars and molten iron tanks.
