SMS Siemag to revamp converter C at Salzgitter Flachstahl
Salzgitter Flachstahl GmbH, Germany, has contracted SMS Siemag (www.sms-siemag.com), Germany, to revamp converter C in its Salzgitter steelworks. Through optimal use of the existing installation space, the specific volume of converter C will be increased by approximately 18 percent, making for a more stable and more efficient production process.
The new converter vessel will be arranged in the trunnion ring by the lamella suspension system, a proven SMS Siemag development, which ensures an unrestrained arrangement of the vessel.
The latest generation of the lamella suspension system, which requires very little maintenance, and the specifically adapted clearance between the vessel and the trunnion ring allow optimum natural cooling and hence the thermal expansion of the vessel in both the axial and radial directions. No extra cooling by air or water is required.
This is the third converter in the Salzgitter Flachstahl steelworks to be revamped using this innovative modernization concept.
Dr. Andreas Berghöfer: “Our experience over recent decades with the lamella suspension system from SMS Siemag has been positive. It is a very safe design, not prone to deformations or wear, and suitable to cope with the harsh conditions and extreme temperature fluctuations prevailing in a steelworks environment.”
SMS Siemag will supply the converter vessel, the trunnion ring complete with the drive, the lamella suspension system for the vessel, the converter bearings and bearing supports. The converter tilt drive will be manufactured in SMS Siemag's workshop in Hilchenbach.
Commissioning is scheduled for the end of 2015.
SMS Siemag AG and SMS Meer GmbH are both companies of SMS group which, under the roof of SMS Holding GmbH, consists of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.
