Abstract
A hot rolling millincludes a control apparatusthat adjusts an angle formed between an upper-side pair of an upper backup rollA and an upper work rollA and a lower-side pair of a lower backup rollB and a lower work rollB in a state where the upper-side pair is kept parallel and in a state where the lower-side pair is kept parallel. The hot rolling millis configured such that the work rollsA andB satisfy the condition that DW/Lb is equal to or smaller than 0.30 where DW is a diameter of the work rollsA andB, and Lb is the maximum strip width of a rolled material, and the hot rolling millperforms rolling in a state where a bending force is applied to the work rolls.
