The performance of the induction melting furnace is closely related to the life of the furnace wall lining

Good chemical stability The chemical stability of the material is closely related to the life of the furnace wall lining. The lining material of the furnace wall should not be hydrolyzed and differentiated at low temperature, and should not be easy to dissolve and reduce at high temperature. During the smelting process of induction melting furnace, it should not be easy to form low-melting substances with slag, and it is not easy to chemically react with metal solutions and additives. Will contaminate the metal solution.

The coefficient of thermal expansion is small and changes with temperature, and the volume should be relatively stable, without rapid expansion and contraction.

It has high mechanical properties and can withstand the impact of the charge in the low temperature state. When the metal is in the high-temperature molten state, it should be able to withstand the static pressure of the molten metal and the strong electromagnetic stirring effect. Under the long-term erosion of the molten metal Abrasion and erosion resistance.

Good insulation performance The furnace wall lining must not conduct electricity at high temperatures, otherwise it will cause leakage and short circuit, causing serious accidents in the induction melting furnace.

The construction performance of the material is good, it is easy to repair and the sintering performance is better, and it is convenient to build and maintain the furnace.
