Abstract
PURPOSE:To reduce die gallings and press cracks and to improve the press formability by descaling a hot rolled steel sheet, then rolling by a limited draft by use of a rolling roll having a limited surface roughness to give a limited roughness to the steel sheet surface, and applying a resin base solid lubricant to the surface and drying. CONSTITUTION:A hot rolled steel sheet 1 is rewound from an uncoiler 2 and is flattened by a leveler 3. Then, the top end of the sheet 1 is cut by a shear 4 and is welded with the rear end of the preceding sheet by a welding machine 5; the sheet 1 is led to a pickling tub 8 through a looper 6, and is descaled. Next, the sheet 1 is subjected to skin pass rolling by a skin pass mill 12 provided with dull rolls dull-worked by lasers. At that time, the sheet 1 is rolled by a draft of 0.3-3.0% by use of rolls having uniform and regular surface patterns worked by laser radiation whose roughness Ra is in the range of 0.7-10mum. A roughness of Ra of 0.5-2.5mum is formed on the surface of the sheet 1, then a resin base solid lubricant is uniformly applied to both faces of the sheet 1 by a back coater 13 and a top coater 14 and is dried by a dryer 15; the sheet 1 is wound by a tension reel 18 through a looper 7.
