<p>PROBLEM TO BE SOLVED: To provide a cold rolling equipment and a cold rolling method therefore capable of manufacturing a product having a prescribed plate thickness distribution and a less edge drop of the plate even in inexpensive equipment. SOLUTION: A cold rolling equipment is provided sequentially with a delivery reel 6 for a steel strip 1, a welding machine 2, a looper 3 and a continuous type cold rolling mill 5 and has the cold rolling equipment and the cold rolling method using the same equipment having a plate profile measuring device 7 to measure the plate thickness distribution in the width direction of the steel strip provided between the delivery reel and the looper, a crown converting device 8 to calculate a plate crown value based on the measurement value by the plate profile measuring device, a computing device 11 of the control output to control one or more among a roll cross angle of the rolling mill, a roll shift volume, a roll bender volume and a roll crown volume based on the output from the converting device.</p> |
