The quality of the furnace lining refractory and the quality of the furnace are related to the melting cost, production cycle and safety factors of the induction melting furnace. At present, the domestic lining materials and furnace building technology have developed rapidly. The appearance of dry ramming materials, coil cement and forming enamel has greatly improved the lining life and safety performance of the induction melting furnace and reduced the smelting cost. Promote the development and progress of induction melting furnace, high quality of lining material, high beating technology, development progress of molding enamel and its popular use rate, development of corundum dry ramming material, development of repair lining material and its technology is induction Research direction and development trend of melting furnace and lining materials.
