Large crystal fused magensia
The environmentally friendly type of water free clay is chosen from Al2O3 - SiC - C material. The main raw materials are bauxite, fused corundum, mullite, coke and silicon carbide. According to the needs of different blast furnaces, high quality anhydrous stemming with different aggregate combinations can be provided. The product has the advantages of easy plugging, good opening, erosion resistance and environmental friendliness. It is suitable for taphole without blast furnace.
