How long can the inner lining of the induction melting furnace be used?

1. The masonry materials for the lining of the furnace wall of the induction melting furnace are mostly quartz sand and high alumina materials. High alumina material is more suitable for induction melting furnaces below 500kg, and the furnace wall lining of induction melting furnaces above 500kg is made of dry quartz sand.

2. Quartz sand is most suitable for smelting furnace. Quartz sand material is made of natural minerals, and its quality mainly depends on the content of SiO2 and its particle size formula. Changing the production of the furnace wall lining can increase the furnace life. The acid furnace wall lining is a furnace wall lining made of acid oxide. The oxide used to make the lining of the acid furnace wall is mainly SiO2. Almost all acid furnace wall linings are made of refractory materials based on SiO2, which are especially suitable for large-scale induction furnaces with a capacity of 5-30T. Through experiments, the first type of physical and chemical indicators of quartz sand has an expansion coefficient of 7%-9%, and the second type has an expansion coefficient of 0.5%-2%. The second type and particle size are more suitable for the use of the furnace wall lining of the induction melting furnace. .
