Rolling mill equipped with a work roll shift function

摘要

A rolling mill equipped with a work roll shift function is provided that can improve yield and realize stable rolling with a simple means. In a six-high rolling mill or a four-high rolling mill, a pair of upper and lower work rolls (2) are provided with tapered portions (2b) in upper and lower positions in point symmetry, shift cylinders (13) are provided for shifting the pair of upper and lower work rolls (2) in roll axial directions and a strip widthwise end position detector (32) is provided for detecting strip widthwise ends of a metal strip (1), and a controller (35) is further provided for performing shift control of the shift cylinders (13) so as to cause taper start positions (2a) of the tapered portions (2b) of the pair of upper and lower work rolls (2) to coincide with the vicinities of the insides of the strip widthwise ends or the vicinities of the outsides of the strip widthwise ends detected by the strip widthwise end position detector (32).
