Abstract
A method for automatically controlling the width of a slab during hot rough-rolling thereof, which comprises: arranging a pair of horizontal broadening rolls each having at least one annular projection in a hot roughing mill train comprising a plurality of roll stands; calculating an amount of roll gap correction of said pair of broadening rolls on the basis of the variation in the width of said slab during hot rough-rolling on said hot roughing mill at the entry of said pair of broadening rolls; and, controlling the roll gap of said pair of broadening rolls in response to said amount of roll gap correction; thereby automatically controlling the width of said slab during hot rough-rolling thereof to a prescribed value at a high accuracy in accordance with the finishing width of a steel strip, and at the same time, automatically correcting variations in the width of said slab during hot rough-rolling thereof at a high accuracy.
