What are the requirements for the use of induction furnace linings?

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

(1) There should be sufficient refractoriness. The refractoriness of the furnace lining material for melting 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, not hydrolyzed and decomposed at low temperature, difficult to decompose and recover at high temperature, and 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 coefficient of thermal expansion is small, the temperature of the furnace lining is constantly changing, there is no crack 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 accept the pressure of alloy liquid and intense electromagnetic stirring effect at high temperature. Under the continuous scouring effect 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 charging charging at low temperature, and can withstand alloy pressure and intense electromagnetic stirring effect at high temperature. Under the continuous scouring effect of alloy liquid, it can be wear-resistant and heat-resistant erosion;

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

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