Reverse rolling process for rolling a steel strip comprises preparing functions independent of the rolling speed, calculating the cross-sectional reduction value of each pass and determining the rolling pass plan from the reduction value

摘要

Reverse rolling process comprises preparing functions A and B in such a way that the product Q produced from A and B is a function that is independent of the rolling speed and where A is defined using a rolling parameter which increases each following pass with respect to the cross-sectional reduction and B is defined using a rolling parameter which is larger in each following pass; calculating the cross-sectional reduction value of each pass in such a way that Q has the same value in each pass; and determining the rolling pass plan from the cross-sectional reduction value.
