COLD ROLLED SHEET

PURPOSE:To manufacture a cold rolled sheet having both workability in pressing and high image clarity after coating by making a steel sheet into a cold rolled sheet provided with respectively different specified roughnesses on the surface and back faces by providing different roughnesses on a pair of upper and lower work rolls for rolling and executing skin pass rolling. CONSTITUTION:The cold rolled sheet on which different roughnesses are respectively provided on the surface and back faces of steel sheet 1 is made by giving different roughnesses to a pair of upper and lower work rolls for rolling and executing skin pass rolling.,) Regular projecting and recessed parts whose diameters (d) are 50-200mum, depth (h) of concave parts is 2-16mum center distance between adjacent concave parts is 0.5-2.5mum are provided on the surface of one side. Random ruggedness of mean roughness Ra of 0.6-1.1mum is provided on the surface on the other side. In this way, the manufacture of the cold rolled sheet having both workability in pressing and high image clarity is enabled, workability in pressing of the steel sheet for automobiles is excellent and the quality problem of crack or the like is completely solved.
