摘　　要：以鞍钢重型机械公司40 t VOD冶炼ZG06Cr13Ni4Mo钢的生产实测数据为依据,根据质量、能量守恒及热力学原理,采用系统工程的分析方法,从操作、化学反应、冶金计量和热化学计量4个层次剖析VOD冶炼过程,建立了VOD冶炼不锈钢的工艺模型。该工艺模型包含冶金模型和热模型,可以根据各输入物料的用量、成分与温度等输入值,方便地求出各输出物料的收得量和成分等输出的预报值。VOD生产结果表明,该工艺模型能较准确地预报VOD精炼需氧量、终点钢水成分及温度等,相对误差低于5%。Based on practical production data of steel ZGO6Cr13Ni4Mo refining by 40 t VOD at Heavy-Duty Machinery Co, Ansteel, and according to conservation of energy and mass and principle of thermodynamics, a process model for steelmaking stainless steel with VOD has been established by using analysis method of system engineering and analyzing on VOD refining process with four level of operation, chemical reaction, metallurgy and thermo-chemical computation. The process model includes metallurgical model and thermal model, with input of variables including charging amount, ingredient and temperature of each material, the predicted data of output including yield and ingredient of each material can be obtained conveniently. Results of VOD production show that the VOD refining oxygen demand, end analysis and temperature of liquid can be predicted by the process model, its relative error is less than 5%.
