铸铁车间无心感应炉修筑炉衬,传统上是使用自耗钢模,以手工或振动围绕钢模捣筑耐火材料,钢模在炉衬烧结时加热熔化,成为第一炉铁水的一部分。新炉衬第一炉熔炼时,工频炉钢模中要装入起熔块。 自耗钢模的主要缺点是筑一次炉衬就消耗一个钢模,增加筑衬费用,特别是大炉子(6吨炉,每个钢模值240英磅;12吨炉,每个钢模值365英磅)。除此之外,还有以下缺点: 1.炉衬尚未完全烧结。坩埚底部先形成熔池,由于铁水过热,使炉衬烧结质量不均匀;
Cast iron workshop heartless induction furnace building lining, traditionally use consumable steel mold, manual or vibration around the steel mold pounding refractories, steel mold in the sintering furnace heat melting to become a part of the first hot metal. The first furnace lining the first furnace melting, the frequency furnace steel mold to be loaded from the frit. The major disadvantage of a consumable steel mold is that it takes one steel mold to build the primary lining, increasing the cost of building linings, especially large furnaces (6 tons of furnaces, each with 240 pounds of steel; 12 tons of steel, each with a steel modulus of 365 British pounds). In addition, there are the following disadvantages: 1. The lining is not completely sintered yet. The bottom of the crucible to form a molten pool at the bottom, due to overheating of molten iron, so that the quality of lining sintering uneven;
