Dry vibrating mix for coreless induction furnace

The Coreless Induction Furnace, commonly known as CIF, is an effective furnace type for smelting of steel, iron, copper, aluminum and alloy, with high melting efficiency, good power saving effect, uniform metal composition, less burning loss, fast temperature rise, easy temperature control and other characteristics, suitable for all kinds of metal smelting occasions.Top performing refractory solutions for this equipment need to strike a balance between the speed of relining and refractory performance.

Intermediate frequency furnace basic dry ramming material is a new type of refractory material. The steel grades smelted in the intermediate frequency furnace are stainless steel 304#, 301#, 204# and other steel grades. Therefore, the raw materials of the ramming material are neutral and basic refractory materials, mainly including: Fused magnesia, high-purity spinel, sintered magnesia and medium and low temperature sintering agents. When knotting the intermediate frequency furnace lining, asbestos cloth must be laid on the inside of the inductor. The thickness of each layer of the furnace wall is 100-140mm, and the thickness of the bottom knot is 300mm. The thickness of the slag line is 120mm, and the wall thickness is 90mm. Oven time ≥ 8 hours. In the application observation, the lining of the intermediate frequency furnace using corundum spinel dry material knotted, the lining is smooth and flat, no cracks fall off, and a layer of 4-6mm slag is formed on the surface, which is conducive to reducing the amount of scrap steel in the lining. Mechanical damage and slag erosion in the process. The intermediate frequency furnace basic dry ramming material is easy to sinter in the steelmaking process, and has a high thermal strength, which can meet the needs of smelting stainless steel. The furnace lining knotted with this kind of ramming material has a service life of 108 times, 80 times, and the average erosion rate of the furnace lining is 0.6mm/furnace, which exceeds the service life of similar foreign products. The forming lining of the intermediate frequency furnace has good integrity, and is easy to construct and dismantle.
