Abstract
PURPOSE: To produce a cold-rolled steel sheet without the necessity of a large amount of rolling mill oil and without marring or wearing a pressure roll, by coating a resin-solid composite powder on the surface of a hot-rolled steel sheet to form a coating film, and then subjecting the steel sheet to cold rolling.
CONSTITUTION: The surface of a lubricating solid powder such as graphite or tlac is coated with a resin such as a (meth)acrylic polymer to produce a resin-solid composite powder. said composite powder alone or, if necessary, together with a watersoluble or water-dispersible resin such as an acrylic resin or an epoxy resin, is coated on the surface of a hot-rolled steel sheet to form a coating film. Then water and/ or an emulsion of a mineral oil are/is sprayed on said coating film. The resulting steel sheet is subjected to cold rolling, and then the coating film is removed by an alkaline dewaxing treatment to produce a cold-rolled steel sheet which exhibits excellent lubricating performance during cold rolling. A pressure roll is little marred or weared. The dewaxing treatment after rolling is easy and the treatment of the dewaxed wast liquid can also easily be carried. Thus, the process does not cause environmental pollution.
