| Abstract | ||
| The cold rolling process is one of the important processes in the Egyptian iron and steel industry. For thorough understanding of the process mechanics and the effect of its key operating variables on its performance, it has to be modelled. Furthermore, modelling of the process helps in building steady state optimization program and achieving high level control strategies aiming at improving its performance. A complete steady state modelling scheme has been applied to the 1200 mm reversing four high mill stand of Helwan Iron and Steel Company. The mathematical model covers the rolling force, the specific torque, the forward slip of the strip at the bite exit, the deflection of the rolls, the maximum stress induced in the roll and the efficiency of the rolling process. Strip thickness of 2 mm and percentage reduction from 10 to 50 % have been considered. | ||
