Title:
PASSING THROUGH SHEET IN CONTINUOUS COLD ROLLING LINE OF METAL STRIP AND ROLLING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3249267
Kind Code:
B2
Abstract:
PURPOSE: To roll metal strips together with a welded bead part by cutting the welded bead part after the tail end of the metal strip and the front end of the following metal strip are welded successfully and easily at the low state of a welded bead height and then passing the steel strip
CONSTITUTION: On the inlet side of a line, the tail end of the metal strip S1 and the front end of the following metal strip S2 are welded by a gas shield arc welding machine to provide an arc by giving pulses of 100-300 pulses/second. After the welding is completed, a rotary stone is pressed to the welded bead so that the height of the welded bead after welding is completed takes a height of ≤10% of the thicknesses of the metal strips S1, S2, moved to the width direction of the metal strip and the metal strip is ground to cut the bead, then, passed through and rolled together with the welded bead.
