Steel strip splicing station

摘要

The front of a new steel strip is welded to the tail of a strip being formed in a continuous pipe mill or the like at an improved splice station. The ends of the strips are sheared to match and are clamped on a carriage movable in the longitudinal direction of the strips. A pair of pinch rolls downstream from the carriage for holding the tail of the strip in the mill can be translated in a direction transverse to the strip for aligning the tail with the front of the new strip of metal. Movement of the pinch rolls and carriage bring the ends of the strips into alignment and abutment. An automatic welder on the carriage butt welds the seam between the ends of the strips. A milling cutter traverses across the welded seam for removing excess weld bead to prevent damage to rolls in the forming mill.
