Abstract
PURPOSE: To increase the spread of slug in the next horizontal rolling, by preparing the shape of the roll of at least one mill in the roughing mills into a drum type pi with 5-40% crown ratio, and by rolling the slug so as to be depressed at the middle portion of upper and lower faces of the slug, in the hot roughing of the slug.
