Product and maintenance efficiency by applying a new concept for pinch-roll change Focus on the rolling and processing industries

Abstract

Siemens VAI Metals Technologies now is able to offer hot-strip mill operators a new method for changing the
pinch rolls in the down coiler. The pinch-roll unit, designed as a quick-exchange cassette, can be replaced
within just ten minutes without additional interruption of production. This saves up to eight hours typically
required by applying conventional solutions. The rolls can be cleaned and refurbished offline, thereby
enhancing strip quality and personnel safety. This capability of rapid pinch roll design furthermore reduces
maintenance time and increases yield.
