Title:
METHOD OF TEMPER-ROLLING STEEL STRIP
Document Type and Number:
Japanese Patent JP2009160626
Kind Code:
A
Abstract:
To provide a method of temper-rolling a steel strip by which rolling load is set in a short period of time when temper-rolling the steel strip.
After calculating rolling load PS(i) to be imparted to the steel strip, resetting is performed on the basis of initial setting load PR(i) for calculation so that the difference between the initial setting load PR(i) for calculation and the rolling load PS(i) falls in the preset allowable range. The rolling load PS(i+1) is recalculated on the basis of the preset initial setting load PR(i+1) for calculation and, after setting actual rolling load PC on the basis of the obtained rolling load PS(i), the steel strip is temper-rolled.
