Abstract
PURPOSE: To manufacture a product slab having no fractures in its side planes and corners, by applying a broadside rolling process to an ingot inclined against the mill center line with a horizontal roll at an early stage of a rolling process, and by applying a straight rolling process with an ordinary universal slabbing mill at a latter stage.
CONSTITUTION: At an early stage of a rolling process, the vertical rolls 3, 3' are fully opened, and an ingot 1 is fed while keeping an inclined position by an angle α≥10° against a mill center line 4 to the horizontal rolls 2, 2' from which the ingot 1 receives a broadside rolling process. Then the opening of the vertical rolls 3, 3' is set to a size equivalent to a prescribed finishing size of breadth, and a straight rolling process is applied to the ingot 1 by an ordinary universal slabbing mill. The said angle α of inclination is desirable to be ≥30°; besides, by altering the direction of inclination α of the ingot 1 from the left to the right for every one pass, or by dividing the angle α equally to the left and the right sides, the broadside rolling process is uniformly performed.
