Refractory material used for Intermediate frequency electric furnace
Acidic, neutral and alkaline refractory materials are widely used in the coreless medium frequency furnace, induction furnace, the intermediate frequency furnace refractories to molten gray iron, ductile iron, malleable cast iron, vermicular cast iron and cast iron alloy, molten carbon steel, alloy steel, high manganese steel,Tool steel, heat-resistant steel, stainless steel, melted aluminum and its alloy, melting copper, brass, copper and bronze, copper alloy, etc.
Medium frequency induction furnace is made of copper tube around the induction coil on the outside of a stove or furnace, metal furnace charge, in the chamber of a stove or furnace when the alternating current through the inductor, to produce alternating magnetic flux circle, through closed metal furnace charge, within a certain depth in the burden surface induced current, make the burden hot melt. And the chamber of a stove or furnace lining made of refractory material, require good erosion resistance, spalling resistance, no crack, long service life.
1. Medium frequency furnace burden is to choose high quality alumina as main raw materials, the use of special chemical raw materials for plastic repair material of bond. He used to package operation, intermediate frequency furnace and other industrial kiln vulnerable, osmosis, erosion, serious parts peeling. Intermediate frequency furnace burden has excellent adhesive, construction is convenient, it is widely used in medium frequency furnace and foundry ladle operation and other industrial kiln of cold and hot repair.
2. Melting aluminium furnace lining refractories (that is, the melting aluminium furnace, molten aluminum refractory furnace burden)In his high alumina materials as the main raw materials, in the composite additive as sintering agent, dry knot in a special additive as seepage control agent.Its special design makes it in use process, which can effectively prevent liquid aluminum infiltration, and solve the burden of the mounted on the surface of slag and the phenomena. The neutral dry lining materials are widely used in no mood to intermediate frequency furnace, induction furnace, to melt aluminum and its alloy, etc.
3. Molten copper furnace lining refractory materialIn his high alumina materials as the main raw materials, in the composite additive for sintering agent, with special additives for seepage control agent of dry knot.Its special design makes it in use process, which can effectively prevent the infiltration of copper liquid, prevent caused by in-depth and oxidation of copper liquid expansion peeling phenomenon. The neutral lining material is widely used in the coreless medium frequency furnace, induction furnace, melting copper and its alloy, etc.
