摘要
为了选择合适的模型来模拟CSP工艺轧制低碳锰钢的组织变化,首先采用Jonas、Sellars、Saito、Yada等人开发的模型进行模拟,然后采用轧卡试验进行了工业试验验证。轧卡试验和计算结果表明:Jonas模型预测的晶粒尺寸在第一道次较实测值偏小,而在最后几道次较实测值偏大;Yada模型预测值较实测值偏小;Sellars和Saito模型预测值与实测数据吻合较好。
In order to choose appropriate models to simulate microstructure evolution of low carbon manganese steel produced by CSP process,models developed by Jonas,Sellars,Saito,Yada were firstly used to simulate the microstructure evolution,then the simulated results were verified by industrial experiments.The experimental and simulated results show that austenite grain size predicted by Jonas model were less than measured grain size at F1 pass,but larger than measured grain size at last several rolling passes;austenite grain size predicted by Yada model was less than measured one at all rolling passes.In addition,the results predicted by Sellars and Saito models were in good accordance with measured data.
