Abstract

PURPOSE: To prevent product defects owing to coiling style defects of hot coils by rolling the rolling top part of the strip to the specific thickness to the fixed length by the surplus weight component than the product weight with the finishing mills then controlling the draft on the way of rolling and finish-rolling the strip to the product plate thcikness.
CONSTITUTION: The strip 3 being taken up by a down coiler is rolled so as to become 2 to 3mm in plate thickness t1 at the rolling top part length L1 from the leading end T up to the thickness changing part α by a finishing mill. Next, the roll gap is changed by controlling the draft on the way of the rolling in succession to this to roll the plate thickness t2 of the length L2 portion up to the trailing end to a product plate thickness of, e.g., 1.4mm or under. This method considerably improves the running characteristic of the strip, improves the flatenss of the rolling top part of the hot strip, eliminates the winding style defect range 2 of the hot coil 1, improves the winding style and increases yeild.
