ROLLING MILL AND ROLLING METHOD

WIPO Patent Application WO/2006/109380

A1

A rolling mill and a rolling method capable of performing uniform wiping in a plate width direction by uniformizing a pressing force against a rolled material in the plate width direction to prevent it from being deformed. The rolled material (S) is wiped by a pair of upper and lower hollow first wiper rolls (12a, 12b) to which crowning shape is applied. The rolled material (S) is further wiped by a pair of upper and lower hollow second wiper rolls (14a, 14b) to which crowning shape is applied while preventing a coolant (C) from being spattered and re-adhered to the rolled material (S). The coolant (C) discharged from near the end part of the rolled material (S) wiped by the second wiper rolls (14a, 14b) is removed by jetting air (A) from the downstream side of the rolled material in the rolling direction.
