Side trimmers in strip processing lines trim endless steel strip to a defined width with high accuracy. Thus, at first an also endless seam is trimmed off both strip edges. In order to enable easy handling of the high quality scrap, the scrap chopper cuts the seam into short pieces. The scrap chopper is an integral part of SMS group’s ASC (Automatic Scrap Chopper) side trimmers.
The product management of the divisions strip processing lines and technical service have jointly developed an advanced design for the proven SMS group scrap chopper knife heads. The goal is a substantial handling and machining time reduction for re-sharpening scrap chopper knives.
The improved knife heads contain knives with two instead of only one cutting edge. The knife edge not in use is protected by the knife clamping piece. When one edge is worn, the knife can be rotated by 180 degrees and refitted immediately.
