摘　　要：降低成本一直是钢铁企业追求的目标。以物料平衡及热平衡为理论基础,结合某钢企的实际工艺装备水平通过合理分摊平均,建立了炼钢过程静态成本预测模型。该模型可以根据入炉原料条件和钢种要求,直接预测炼钢厂的吨钢成本,具体包括转炉、精炼、连铸的工序成本以及钢铁料、合金、脱氧剂、造渣料、氧耗成本等成本明细。将模型应用于生产实践后,模型的预测值可信度高,可以有效反映原料条件变化引起的成本变化,且预测值和实际值偏差小,能够真实地反映企业的冶炼成本,为节本增效、改善工艺提供参考。Reducing cost is always the goal of steel enterprises.Based on the theory of material balance and heat balance,combined with the actual technological equipment level of a steel enterprise,a static cost prediction model is established by reasonable allocation average.According to the raw material conditions and steel grade requirements,the model can directly predict the per ton steel cost of steel making plant including the process cost of converter,refining and continuous casting,and the cost details of steel,alloy,deoxidizer,slag-making material and oxygen consumption cost.After the mode is applied to production practice,the prediction value of the model has high credibility,which can effectively reflect the cost change caused by the change of raw material conditions;and the deviation between the predicted value and the actual value is small,which can truly reflect the smelting cost of the enterprise,and provide reference for cost saving,and process improvement.
