Intermediate frequency furnace lining material is also known as intermediate frequency furnace charging material, intermediate frequency furnace dry vibration material, intermediate frequency furnace dry punching material, intermediate frequency furnace ramming material, etc., acid, neutral, basic lining material, acid lining material is high purity quartz, molten quartz as the main raw material, with composite additives as the sintering agent; The neutral lining material is aluminum oxide and high aluminum material as the main raw materials, and the composite additive as the sintering agent; The basic furnace lining is made of high purity fused alumina, high purity fused magnesia and high purity spinel as the main raw materials, and composite additives as the sintering agent.

        Basic lining: mainly used to melt all kinds of high alloy steel, carbon steel, high manganese steel, high chromium steel, tool steel, stainless steel and other alloy steel.

        Acid lining: mainly used for melting, heat preservation of cast iron coreless induction furnace working lining.

        Acid, neutral, basic lining material is widely used in coreless IF furnace, cored induction furnace, as if furnace lining material used to melt gray cast iron, ductile cast iron and cast iron alloy, melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, melt aluminum and its alloy, melt copper, brass, white copper and bronze and other copper alloys.

        There are two knotting methods for intermediate frequency hot induction furnace lining: wet knotting and dry knotting. Both methods can be used for acidic intermediate frequency lining, neutral lining and basic lining.

        Intermediate frequency furnace wet knotting refers to the knotting by adding water, water glass, brine and other adhesives into the knotting material of the furnace lining. Because the knotting material contains a certain amount of water, it has less dust and good formability during construction. However, wet knotting also has a series of shortcomings: the lining material of intermediate frequency furnace knotting is not dense enough, and the refractoriness of the lining is decreased; The drying time of the lining is longer. When the moisture in the furnace lining vaporizes, the insulation performance of the sensor decreases. Poor treatment often leads to the breakdown of the inter-turn fire, and may also cause the grounding short circuit, therefore, for the larger melting medium frequency furnace should try to avoid the use of wet knotting furnace lining.

        Dry furnace construction method is currently obtained in the furnace of crucible induction furnace. Wide range of applications. Dry medium frequency furnace method without cementing agent can be used. The fire resistance of the lining material is maximized, the sintered layer of the lining is thinned, the powder layer is thickened, the heat loss of the lining is reduced, the tendency of the lining crack is reduced, and the reliability of the lining is improved
