Design of dedicated hydraulic power pack for wiper system of sendzimir mill

2023年11月14日  The sendzimir mill is the mother unit of CRM (cold rolling mill) which is used to roll the metal sheets (stainless steel). The wiper system is used to wipe out the excess coolants from the strips. If wiping is not done efficiently it will be hazardous to the environment and to workers when subjected to annealing.
