Abstract

PURPOSE: To materialize the sawing as planned, when the sawing plan of the product is previously given, by correcting the finishing size according to its excess length, by deciding the real pass schedule, and by deciding the roll gap of each rolling stand.
CONSTITUTION: The product assortment plan is made for the product of the rolling; the excess length according to the product sawing plan is calculated; and the calculated excess length is compared with the specified range. And, when the calculated excess length is out of the specified length, the pass schedule is corrected so as to make the finishing size to be in the tolerance; the excess length is again calculated depending on the rolled length by rolling the rolled material according to the corrected pass schedule through which the excess length is obtained within the specified range, is established; hereby, the roll gap of each rolling stand is decided.
