Prediction Model and Software Development for Microstructural Evolution in Thin Strip Casting and Rolling Process
To accurately predict the microstructural evolution during the rolling process on the endless casting&rolling production line,this paper integrates the characteristics of endless casting&rolling equipment and production processes.Based on heat conduction theory,a temperature field simulation system for the entire endless casting&rolling process is developed.Utilizing the JMAK model and coupling it with temperature evolution,a microstructural evolution prediction model suitable for the endless casting&rolling production line is derived.Furthermore,a user-friendly,interactive software application is developed using Python and PyQt to implement the prediction model.By comparing the model's calculations with actual production data,the results show that the temperature prediction error is within±5℃and the grain size prediction accuracy is within±3μm.This meets the production requirements of the endless casting&rolling line and provides reliable theoretical support for the formulation and optimization of endless casting&rolling processes.
