Patent number: 8720244Abstract: The present invention provides a method for supplying lubricant to various kinds of steel sheets with different qualities in cold rolling without any restrictions, such as lubricant supplying apparatus or lubrication conditions. This method comprises storing two or more kinds of lubricant such as A and B, having different compositions, selecting one lubricant or a mixture lubricant of the above A and B in accordance with the friction coefficient between the steel sheet to be cold rolled and a work-rolls, and supplying an emulsion comprising a mixture of the lubricant A and/or B and heated water.Type: GrantFiled: November 17, 2005Date of Patent: May 13, 2014Assignees: Nippon Steel & Sumitomo Metal Corporation, Arcelor FranceInventors: Yoshiki Takahama, Toshiyuki Shiraishi, Shigeru Ogawa, Luc Vanel, Guy Hauret, Maxime Laugier, Pascal Masson
