Abstract
PURPOSE: To improve the yield of hot rolled sheet steel and decrease edge drop by finishing the sheet steel by light screw-down rolling of predetermined draft range in its final finish rolling.
CONSTITUTION: In the upper stream rolling stands up to the final finish rolling, a sheet steel is kept thinner than in the prior art, thence in the final finish rolling, it is hot rolled under light screw-down of 1.5W7% drafts. As a result, roll deflection and flattening are decreased, hence edge drop is considerably decreased. As compared to conventional hot rolling, sheet crown is reduced, and the hot rolled sheet steel of which the shape after the rolling generally shows a tendency to slight center elongation is obtained.
