  During the use of the intermediate frequency furnace , the thickness of the refractory used for the furnace lining is only 70-110mm. The inner side is in contact with the high-temperature molten metal, and the outer side is close to the water-cooled coil. The temperature difference between the inner and outer sides of the refractory is large. Under the conditions of use in aggressive environments. The main process conditions that affect the damage of the furnace lining include: smelting temperature, degassing time, one-time degassing amount, chemical composition of slag and steel (iron) type produced. The main influencing factors that damage the furnace lining are: chemical corrosion of slag, flaking of refractory structure and thermal corrosion. As the furnace capacity increases, the proportion of heat lost from the surface of the molten steel decreases. The slag temperature is higher than that of a small-capacity furnace, and the fluidity o

 Cast steel brick is made of clay, shale, coal gangue or fly ash as the main raw materials , and the solid or void ratio is not greater than the specified value and the overall dimension meets the requirements. The brick with clay, shale, coal gangue and fly ash as the main raw materials, which is formed and roasted, is called cast steel brick. Refractory materials used in China's electric furnace cover include spinel with low expansion coefficient, zirconia added to mullite and other materials to toughen with its phase change, and steel fiber.?
