Abstract
PURPOSE: To improve productivity and yield by properly adjusting the roll gaps of only the 1st stand at the time of passing the lap fillet weld zone of preceding and succeeding coils through cold tandem mills.
CONSTITUTION: The trailing end of a preceding coil 7 and the leading end of a succeeding coil 3 are connected by lap fillet welding with a welding machine 4. Next, at the time when this lap fillet weld zone 8 arrives at just before the 1st stand 1-1 of cold tandem mills 2, the position thereof is detected with a touch roll 5. Cooperatively with the detection signal of the roll 5, the roll gap adjusting device of the stand 1-1 is operated to change the roll gap to a gap that permits biting-in of the weld zone 8. At the time when the weld zone 8 arrives at the screw down part of the stand 1-1, the mills are stopped to return the roll gap to the original gap and screw down the weld zone 8, after which the ordinary rolling is resumed in succession. After it is rolled to prescribed thickness and is coiled to a prescribed size, it is cut with a shear 6.
