摘要: 针对某钢厂铝镇静钢LF造渣过程存在渣量和终渣成分波动较大的问题,结合SPHC钢种通过物料平衡,建立了基于铝脱氧工艺的脱氧造渣模型。模型采用VB6.0语言编制为离线验证软件,将现场采集的SPHC冶炼数据代入模型进行了验证。结果表明:无论是物料加入量还是终渣成分,稳定性都得到了很大提升,精炼操作的稳定性和钢液质量得到了保障;各炉次吨钢终渣量稳定,均方差值由2.95降到了0.93;计算的吨钢终渣量平均值比工厂低2.41 kg/t,节省了原材料。

Abstract: In order to solve the problem of the instability of slag quantity and end slag composition in the aluminium killed steel production process with LF in some factory, a deoxidation slagging model was proposed based on mass balance in SPHC production and aluminum deoxidization process. The model was written as offline test software by VB6.0, and it was run to test the result with input the field smelting data of SPHC. The results showed that, the stability of materials quantity and end slag composition was promoted greatly, and the stable refining process and good molten steel quality were well. The mass of slag calculated kept stable since the mean square deviation was decreased to 0.93 from 2.95. The mass of slag formed per ton of steel could reduce 2.41 kg in the calculation when compared with the factory.

Key words: LF, slag-forming model, secondary refining, deoxidization process
