Abstract

PURPOSE:To prevent the deterioration of quality of a rolled product, by making a simple roll arrangement capable of controlling the rolling mill in various conditions ranging from a point symmetry to a point asymmetry. CONSTITUTION:A rolling mill is constituted of following members; a couple of upper and lower word rolls 2, 3 for directly rolling a strip 1; two axially shiftable intermediate rolls 6, 7 arranged between the said roll 2 and an upper backup roll 4; and another axially shiftable intermediate roll 8, in a number different from that of the former intermediate rolls 6, 7, arranged between the roll 3 and a lower backup roll 5. The said intermediate roll 7 corrects the point asymmetry of this rolling mill, so that even if the upper and lower work rolls' diameters are different from each other or nonuniform blank materials are fed to this rolling mill, a rolled product in a high quality can be manufactured.
