摘要 以文献 [1]中提出的数学模型处理了奥氏体型不锈钢的AOD精炼过程 ,并以在 18tAOD炉中生产 1Cr18Ni9型钢得到的 32炉数据作了检验 模型估计结果与实测值相符 The new mathematical model presented in Part 1 of the present work were used to deal with the austenitic stainless steelmaking and tested on data of 32 heats obtained in producing 1Cr18Ni9 grade steel in an 18 t AOD vessel. The results predicted by the model are in excellent agreement with the determined data. The model can provide some useful information and a reliable basis for optimization of the technology of the AOD refining process of stainless steel and control of the process in real time and on line.
