Calculation of energy-power parameters of cold rolling of strip made of 3.10...3.20 % Si transformer steel on reversing mill

This paper examines the cold rolling of transformer steel with particularly low specific magnetic losses, which arises during production on a single-stand 1400 reversing mill. The mill’s design allows for both four-high and six-high mill configurations. The energy-power parameters of the transformer steel rolling process on the mill are determined for different mill configurations. The adequacy of the calculation method used is assessed, and the feasibility of rolling transformer steel strips of minimal thicknesses is examined. Analysis of the calculation results demonstrates that when using the six-high 1400 mill with 150 mm diameter rolls, the average metal pressure on the rolls is significantly lower compared to the four-high mill configuration.
