Development of Pass Schedule Calculation Procedure for Single-Stand Reversing Cold Rolling Mill

In this paper, pass schedule calculation method for single-stand reversing cold rolling mill is introduced. Newton－Rapshon method is used to solve non-linear equations composed of each pass loads according to equal power rolling strategy. After the thickness of each pass is calculated, rolling parameters of each pass is obtained by modification. Based on the method pass schedule calculation procedure is developed. The practical application shows that calculation result of program is close to the actual data, and the speed and stability of the procedure can meet the requirement of on-line process control, so it is suitable for the single-stand reversible cold rolling mill.
