Intermediate frequency furnace ramming material


Intermediate frequency furnace ramming material has many names, including dry ramming material vibration of intermediate frequency furnace, medium frequency furnace lining materials, intermediate frequency furnace refractory material, and intermediate frequency furnace dry vibration material. All those names are saying the same refractory product, and the properties and usage of all of them are the same. Intermediate frequency furnace ramming material refers to a kind of unshaped refractory products which are applied in the method of ramming (by human or machine), and then becomes hard in heating.

According to chemical properties, ramming material can be divided into acidic, neutral and alkaline ramming material. Acid intermediate frequency furnace ramming material is mainly made from high purity quartz and fused silica. During composite period, sintering agent uses composite additive as main material. Neutral intermediate frequency furnace ramming material uses alumina, high alumina material as main raw materials, it also uses composite additive as sintering agent. What makes alkaline ramming material different from the above two kinds of ramming materials is that its main raw materials are high purity fused corundum, high purity fused magnesia and high purity spinel. And also it uses composite additive as sintering agent. The above three kinds of ramming materials which are acidic, neutral and alkaline intermediate frequency furnace ramming materials are widely used for coreless intermediate frequency furnace and cored induction furnace.

Intermediate frequency furnace ramming material is used for melting of cast iron, ductile iron, forging cast iron, vermicular cast iron and cast iron alloy, carbon steel, alloy steel, high manganese steel, tool steel, heat-resistant steel, stainless steel, aluminum and its alloy, copper, brass, copper nickel alloy and bronze copper alloy, etc.
