河北钢铁集团邯钢分公司在炼钢系统推行转炉低成本终渣循环炼钢法,在冶炼过程中充分利用高碱度的终渣,在吹炼前期适当时机倒出脱磷渣再进行二次造渣,从而实现降低渣料和钢铁料消耗,降低生产成本的目的。应用该工艺后,石灰消耗降低29.3%,转炉渣量减少32.8%,钢铁料消耗降低5 kg/t,取得了良好的经济效益。
Handan Iron and Steel Branch of Hebei Iron and Steel Group, the implementation of the converter system in the steelmaking system of low-cost end-of-cycle steelmaking method, in the smelting process take full advantage of the high alkalinity of the final residue, the appropriate timing in the pre-blowing out of dephosphorization slag and then the second Slagging, in order to achieve the purpose of reducing the consumption of slag and steel materials, reducing production costs. The application of the process reduced the lime consumption by 29.3%, reduced the amount of converter slag by 32.8% and reduced the consumption of steel material by 5 kg / t, which achieved good economic benefits.
