Press Releases Siemens Drives & Gears Retrofit Produces Increased Efficiencies at Corus
A total of nine Siemens drives, including five on heat treatment furnace roller tables, and four on a roller table and tempering furnace, were installed. The earliest of these installations has now been running for 18 months without any problems, and the others for eight months. The Corus plant manufactures specialist, niche-market, high-strength steel products at this site. Corus manufacturing manager Jim Cossar said he had not previously used geared motors on this type of plant, but had been experiencing reliability problems with the existing hydraulic units in these areas, which was compromising production throughput. Speed matching was becoming an increasing problem for the roller tables conveying steel from the furnaces. In contacting Industrial Automation & Controls (IAC), who had carried out previous work for Corus, he stressed that he was looking for better positional controls within the furnace and wanted German engineering with Siemens drives for reliability. IAC recommended the Siemens controls/Flender geared motors combination. The Flender electric geared motors (size Z168), associated Siemens controls and Siemens 6SE70 AC drives/inverters were all subsequently fitted by IAC to the busy plant. Jim Cossar said that Corus at Clydebridge had trebled its output in the last two years, partially through making production efficiency improvements such as these.

An increase of 30% in throughput leading to significantly improved efficiency was gained by Corus Construction & Industrial (Long Products Division) at its Clydebridge works after Flender gear units and Siemens drives were selected.
