Introduction to the requirements of induction furnace lining materials

Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to understand the basic requirements of induction furnace lining materials:

(1) It should have sufficient refractoriness. The refractoriness of the lining material for smelting cast iron should be greater than 1650-1700 degrees Celsius, and the softening temperature should be higher than 1650 degrees Celsius;

(2) Good chemical stability, no hydrolysis and differentiation at low temperature, not easy to decompose and reduce at high temperature, not easy to produce physicochemical reactions in metal alloy liquid, slag, additives, etc., and produce metallurgical reactants during the smelting process;

(3) The thermal stability is good, the thermal expansion coefficient is small, the temperature of the furnace lining is constantly changing, no cracks appear due to uneven heating, the volume should be stable, and there is no severe expansion and contraction to deform the furnace lining;

(4) Good mechanical properties, can withstand the impact of charge charging at low temperature, and can withstand the pressure of alloy liquid and strong electromagnetic stirring at high temperature. Under the continuous scouring of alloy liquid, it can be wear-resistant and heat-resistant erosion;

(5) Good insulation performance, the furnace lining material can withstand the impact of charge charging at low temperature, and can withstand alloy pressure and strong electromagnetic stirring at high temperature. It can be wear-resistant and heat-resistant erosion under the continuous scouring of alloy liquid;

(6) Good knotting performance, easy repair and sintering performance, convenient knotting and maintenance, and furnace lining materials should be easily purchased in the market.

To meet the above basic requirements can be regarded as induction furnace lining materials
