Numerical simulation of the temperature fields of stainless steel with different roller parameters during twin-roll strip casting

摘要

The temperature field of stainless steel during twin-roll strip casting was simulated by experiment and a finite element (FE) model. By comparing the measured result with the simulated values, it is found that they fit close to each other, which indicates this FE model is effective. Based on this model, the effects of roll gap (0 and roll radius (R) on solidification were simulated. The simu-lated results give the relationship between t or R and the position of the freezing point. The larger the t is and the smaller the R is, the closer the position of the freezing point is to the exit.
