The refractory charge for the intermediate frequency melting furnace is as follows:

Acid, neutral, alkaline and composite materials ; four seasons fire refractory

Medium frequency melting furnace refractory material is also called medium frequency melting furnace lining material, medium frequency melting furnace dry vibration material, medium frequency melting furnace smashing material, medium frequency melting furnace ramming material, acid, neutral and alkaline refractory materials, acid refractory material is High-purity quartz and fused silica are the main raw materials, and the composite additive is used as the sintering agent; the neutral refractory material is made of alumina and high-alumina materials, and the composite additive is used as the sintering agent; the alkaline refractory material is high-purity electrofusion. Corundum, high-purity fused magnesia, high-purity spinel is used as the main raw material, and the composite additive is used as the sintering agent. Acidic, neutral and alkaline refractories are widely used in coreless intermediate frequency melting furnaces and cored induction furnaces. They are used as intermediate frequency melting furnace refractories to melt grey cast iron, ductile iron, calcinable cast iron, vermicular cast iron and cast iron alloy. , melting carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys, melting copper alloys such as copper, brass, white copper and bronze.
