一 问题的提出 我厂自一九八一年十月份开始用碱性中频感应炉重熔不锈钢以来,炉胆的寿命一直很短,平均为每打一只炉胆开20次左右,还常出现方铜管冒烟、穿钢水等现象。炉子的利用率很低,影响了生产正常进行,经济效益很差。另外,劳动强度大,安全性差。 目前国内外报道资料中,有的采用电熔镁砂或氧化铝—氧化铬材料,使炉龄提高到近百炉,但是,这样做势必使炉胆的成本提高;有的采用高铝钒土筑中频炉坩埚,尽
A question raised I plant from October 1981 started with alkaline IF induction furnace remelting of stainless steel, the life of the furnace has been very short, with an average of about 20 times per furnace bile open, often appear Party brass smoke, wear molten steel and so on. Low utilization of the stove, affecting the normal production, poor economic efficiency. In addition, labor-intensive, poor security. At present, the information reported at home and abroad, and some use of fused magnesia or alumina - chromium oxide material, the furnace increased to nearly one hundred furnace, but it is bound to make the cost of the furnace to improve; some use high alumina bauxite Build intermediate frequency furnace crucible, make
