Abstract

PURPOSE:To improve the surface condition of the product, by shifting the centers of the inner work rolls to the specified directions from the center line connecting the centers of two outer work rolls, and by making the deflector roll to contact with the inner work roll from the same direction through the intermediate roll. CONSTITUTION:The center A of the feed-in side work roll 6 is shifted to the run- out side from the center line l connecting the centers O, O of the outer work rolls 8, 9, and besides, the deflector rolls 13, 15, contacting with the work rolls 6, 7, respectively through the intermediate rolls 12, 14 are arranged in the directions of shifting the rolls 6, 7. For this purpose, the rolling work is applied to the material S under the tensions T1, T2 being approximately parallelly turned up without being wound around the rolls 6, 7. Accordingly, the lubricant or the coolant can be supplied to the required place. For example, the lubricant is supplied to the front and the back surfaces of the material S from the nozzles 16-21, and the coolant is supplied to the surfaces of the rolls 6, 7 and 8, 9 from the nozzles 22, 23 and 24, 25; hereby, the deterioration of the surface condition of the product and the increase of the rolling load are possible to be prevented.
