摘　　要：炼钢过程铁合金减量化有助于钢铁企业节能减排,并可节约其生产成本。本研究采用转鼓实验、数据分析和钢水量校准等方法,考察了合金粉化率、合金成分、合金收得率等对合金成本的影响。结果表明,合金粉化率升高,合金元素的收得率降低;当硅锰合金中Mn含量由64.7%提高至66.6%时,每吨钢的合金化成本由243.62元下降至241.89元,升高合金品位可降低合金消耗量。当钢水量偏差在-2%~0范围内时,合金化成本最低。因此,钢铁企业应定期检查钢包秤的精准度。The reduction of ferroalloys consumption in the steelmaking process helps steel companies to reduce emissions through energy conservation and save their production costs.In this paper,drum experiments,data analysis,and calibration methods of the molten steel weight were used to study the effects of alloy pulverization rate,alloy consumption,and alloys yield on alloy cost.The results show that the alloy yield rate decreased when the alloy pulverization rate increased.The alloying cost per ton of steel decreased from 243.62 yuan to 241.89 yuan when the Mn content of silicon manganese alloy increased from 64.7%to 66.6%.The alloying consumption decreased when the content of the alloying elements increased.The cost of the alloy was the lowest when the steel water deviation is in the range of–2%–0.Therefore,steel companies should regularly check the accuracy of ladle scales.
