Abstract

PURPOSE:To enable the ommision of the pickling line to be held in front of the cold rolling line, by coating a scaled surface of a hot rolled steel sheet with an organic resinous compound, and additionally, by supplying an unmixed oily lubricant to the surface of the sheet when undergoing the cold rolling work. CONSTITUTION:At cold rolling the hot rolled, black skinned steel sheet, a water soluble resinous compound, containing as the water soluble group, the carboxyl group like as the acrylic resin of acidity higher than 50-100, the polyester resin, the oleoresinous epoxy ester resin, etc., is applied to the surface of steel sheet which is then dried up at 60-70 deg.C. Next, when this steel sheet is cold rolled, an unmixed oily lubricant is supplied in order to reduce the friction between the rolling roll and the steel sheet. This lubricant is prepared from a single or a mixture of two or more kinds of mineral oil, oil and fat, and synthetic oil, by adding it one or more than two kinds of fatty acid, higher alcohol, fatty ester of polyhydric alcohol, amino compound, wax, organic phosphate ester, etc. According to the present method, the scale removal does not cause during the cold rolling work, and the wear of the rolling roll is decreased.
