PURPOSE:To improve the productivity of an austenitic stainless steel strip by changing the flow rate of a coolant at every rolling pass and executing cold rolling. CONSTITUTION:The austenitic stainless steel strip 1 is cold rolled by work rolls 4. The steel strip is rolled with the flow rate of the coolant changed by using a coolant flow rate control valve 6 from a coolant supply piping 5 at every rolling pass. The high draft is secured in this way and the number of rolling passes is decreased. |
