Abstract
PURPOSE: To make possible the product to be manufactured with the exact aim dimensions, by measuring the material size before the final rolling pass, by comparing the measured value with the aim material size of the final pass, and by changing the material thickness in the final pass for obtaining the aim material size.
CONSTITUTION: The final thickness TF to be obtained by the broadside rolling is calculated according to the formula (I) (α is the correction term), in which T1 is thickness of the slab 10 before starting the broadside rolling, SH is its breadth, and δH is the aim breadth; the broadside rolling is carried out in the arrowed direction L and in the perpendicular direction W, aiming at the thickness TF; and the rolled length PH and thickness Pt of the slab 12 before the final pass are measured. This length PH becomes the breadth δH of the final rolled product 14, obtained from the final pass applied to the slab 12 being turned 90 degrees. The final thickness TF obtained by the broadside rolling is recalculated according to the formula (II) (β is the correction term), and the rolling is applied to the material so as to make the final breadth to be TF after the final pass; hererby, the exact aim breadth δH is obtained. These calculations are automatically operated by the computer. When the aim rolled length is required, the exact aim length can be obtained by similarly changing the material thickness in the final rolling pass.
