Improved hot and cold rolling of steel strip

Abstract

The potential for decreasing the end thickness of hot-rolled strip in traditional broad-strip rolling mills is demonstrated. The change in thickness depends on the temperature difference over the length of the hot-rolled intermediate strip. Additional reduction of the rear end of hot-rolled intermediate strip is worthwhile for other reasons. The rolling of thinner rear ends of hot-rolled strip in continuous cold-rolling mills decreases the loss of metal in end trimming.
