Abstract
PURPOSE: To secure the stability of rolling and perform the material adjustment of steel sheets through controlling of draft over a wide range by using the work rolls which are specified of the ratio between work roll diameter and the thickness of steel sheets.
CONSTITUTION: In the case of performing skin pass rolling of a steel sheet for surface treatment, the ratio D/t between the work roll diameter D of the skin pass rolling mills and steel sheet thickness t is made 2,000 or less (particularly 1,500 or less) and the wet type skin pass rolling is done. If the work roll diameter is small, the angle of bite of the material to be rolled increases and Luueders' bands 1 are produced deeply and densely in the material to be rolled in the early stage of bite. Because of this, the yield point elongation in the roll gap is erased early and rolling stability increases. According to this invention, the wet type skin pass rolling of draft 5% or less may be executed without the occurrence of jumping phenomena. It is also possible to selectively make the steel sheets provided with various materials from the same blank.
