<p>PURPOSE:To reduce the variance of an edge part of rolling sheet, and to improve the cutting efficiency of sheet edge and the yield of a product as well, by estimating the amounts of width spread, restoration and cooling shrinkage, and regulating the width of a stock by cutting, in shape adjusting rolling by a pair of horizontal and vertical rolls. CONSTITUTION:In adjusting rolling the shape and dimensions of a stock to be rolled by combining and arranging a pair of horizontal rolls and a pair of vertical rolls; the amount of width restoration of a rolled sheet after rolling the stock by the horizontal rolls, the amount of width spread after rolling the sheet by the vertical rolls and the amount of cooling shrinkage after rolling, are estimated to regulate the width of stock by cutting. In case of reducing the variance of projected sheet edge by rolling this regulated stock and cutting the sheet edge; the capacity of a cutting device is made small by making the amount of cutting uniform and small, and the cutting efficiency is improved as well as the yield of product is enhanced.</p> |
