Furnace lining refers to the furnace wall of induction melting furnaces or other furnaces used to refine metal. It is an important part of the working process of induction furnaces. The quality of furnace lining can directly affect the working efficiency of the electric induction furnaces. As high-temperature smelting equipment, the temperature resistance of the furnace lining must be the main standard to judge the furnace lining. So how can we improve its temperature resistance?
