Abstract
In a method of controlling the roll gap of a cold rolling mill of the class wherein the rolling load is first estimated and then the roll gap is calculated, the deformation resistance of the material being rolled is determined in accordance with a constant determined by the reduction, the strain rate, and the temperature and quality of the strip being rolled; the exit strip temperature is determined by taking into consideration the reduction and the characteristics of the rolling mill; the mean deformation resistance of the strip is determined from the deformation resistance and the exit strip temperature; the rolling pressure is calculated in accordance with the equation as hereinbelow defined for determining the rolling pressure by using the mean deformation resistance; and then the roll gap is determined and controlled in accordance with the equation of a gauge meter as hereinbelow defined.
