FACILITY AND METHOD FOR COLD ROLLING METAL STRIP
Document Type and Number:
WIPO Patent Application WO/2017/183620
Kind Code:
A1
Abstract:
A facility for cold rolling a metal strip using a circulating-lubrication system, for jetting a low-concentration coolant in the vicinity of the entry side of a work roll, jetting a high-concentration coolant further upstream than the jetting position of the low-concentration coolant, and performing rolling, wherein the metal strip is cold rolled using a facility for cold rolling a metal strip having a control facility for changing the jetted amount of the low-concentration coolant in accordance with the rolling speed so that the distal end of a pooling of the low-concentration coolant formed on a plate surface of the entry side of the work roll does not reach the jetting position of the high-concentration coolant, whereby rolling is possible without losing plate-out properties even when the rolling speed is reduced.
