Abstract
PURPOSE: To perform stable rolling of a high draft of ≥50% per pass in cold rolling using rolling oil or the like by forming a chemical conversion film such as phosphate beforehand on the surfaces of a steel plate.
CONSTITUTION: After a hot-rolled steel plate is pickled and descaled, it is subjected to a chemical conversion treatment quickly by a dipping method or the like to form a film of phosphate or oxalate on the surfaces of the steel plate. The coating weight of the film is 0.1W10g/m2. Rolling oil of mineral or fat type of ≤15cSt viscosity at 40°C is used by a direct system or recirculation system in the rolling. In lieu of the rolling oil, water soluble rolling fluid consisting essentially of alkylalcohol polyethylene phosphate or the like may be used. If the peripheral speed ratio of the work rolls of rolling is set at a different peripheral roll of ≤1.0/1.5, the stable cold rolling of a draft attaining ≥50% and up to 70% per pass or per stand is made possible, the surface flaws of products are eliminated and the abrasion of the rolls is minimized.
