SIRIO ZIEH ÖL STATION

CONTROL SYSTEM
.. SIEMENS 1513F-1 PN

1. General Description
The draw oil preparation system is designed for the optimal treatment of unprocessed tubes prior to the drawing process. A large-volume draw oil bath ensures homogeneous coverage of the tube surfaces. This guarantees consistent lubrication, reduces friction resistance during drawing, improves the surface quality of the tubes, and increases tool service life. A constant material flow and stable bath temperature and quality make this system a key step in efficient tube manufacturing.
