为了在铁水预脱磷工艺中利用不锈钢炼钢厂含铬镍混轧铁皮及回收有价金属,按不同配比用含铬镍铁皮替代烧结矿粉,配成不同成分的脱磷剂,进行了熔化性实验和铁水预脱磷实验。实验结果表明,在脱磷剂中石灰、萤石等非铁成分与铁氧化物配比小于1的情况下,用含铬镍混轧铁皮替代50%的外购烧结矿粉的实验方案是可行的。 In order to use molten iron pre-dephosphorization process of stainless steel mill containing chromium-nickel mixed rolling metal and recovery of valuable metals, with different proportions of chromium-containing nickel-iron skin instead of sintering powder, dubbed different composition dephosphorizer, carried out Melting experiments and hot metal dephosphorization experiments. The experimental results show that it is feasible to replace 50% of the purchased sinter powder with chromium-nickel mixed rolling iron in the dephosphorization agent when the ratio of non-ferrous components such as lime, fluorite and iron oxide is less than 1 of.
