What material is used for the lining of the intermediate frequency furnace

The lining material of intermediate frequency furnace is also called intermediate frequency furnace charge, intermediate frequency furnace dry vibrating charge, intermediate frequency furnace dry charge, intermediate frequency furnace ramming charge, etc. It is divided into acidic, neutral, and alkaline furnace linings. The acidic furnace lining is made of high-purity quartz, Fused silica is the main raw material, composite additives are used as the sintering agent; the neutral furnace lining is made of alumina and high aluminum materials as the main raw material, and the composite additive is used as the sintering agent; the basic furnace lining is made of high-purity fused corundum, high-purity Fused magnesia and high-purity spinel are used as main raw materials, and composite additives are used as sintering agents.

Do

Alkaline furnace lining: Mainly used for melting various alloy steels such as high alloy steel, carbon steel, high manganese steel, high chromium steel, tool steel, stainless steel, etc.

Acid lining: Mainly used for coreless induction furnace lining for melting and heat preservation of cast iron.

Do

Acidic, neutral, and alkaline lining materials are widely used in coreless intermediate frequency furnaces and cored induction furnaces. They are used as intermediate frequency furnace lining materials to melt gray cast iron, ductile iron and cast iron alloys, and to melt carbon steel, alloy steel, and high manganese. Steel, tool steel, heat-resistant steel, stainless steel, melting aluminum and its alloys, melting copper alloys such as copper, brass, cupronickel and bronze, etc.
