Computer Simulations Of The If Steel Ferritic Rolling Process

Rolling force is the most important factor of process schedule during hot rolling. It is the key to determine the precision of guage of the finished product and to effect the load of the mills. The pivotal factor of predicting rolling force is flow stress.The aim of the thesis is to setup a new mathematics model and develop a simulation software of ferrite rolling of IF steel .in order to determine the softing mechanics and look for the best process schedule, the Simulation of anstenite rolling & ferrite rolling is launched .Through studying, the mathematics model of the flow stress of the IF steel is setup in the way of modification of coefficient. The result of calculation makes a good fit with the data of experience.In this paper, rolling force of anstenite rolling and ferrite rolling under different process schedule is calculated. The result is compared with that of measurement, which indicates the software can precisely predicts rolling force of IF steel. On this basis, a new temperature schedule suitable for rolling force has been founded.This software developed in our research is a auxiliary tool by which the technician develop new products. It is a part of Computer Simulation of Ferrite Rolling for IF steel, and the base of on-line prediction and control system of IF steel. It is of great practical utility.
