Siemens to Replace ThyssenKrupp Nirosta Converters

11/13/2007 - Stainless steel producer ThyssenKrupp Nirosta places order with Siemens Metals Technologies to replace two AOD converters at the company's plant site in Krefeld, Germany.

German stainless steel producer ThyssenKrupp Nirosta, Germany, recently placed an order with Siemens Metals Technologies to replace two AOD (Argon-Oxygen Decarburization) converters at the company's plant site in Krefeld, Germany.
 
Replacing the converters will enable the company to maintain its production of stainless steel on a long-term basis, while also helping it to reduce its operational and maintenance costs.
 
Siemens will replace two existing two stationary AOD vessels at the company’s ThyssenKrupp Nirosta's Krefeld plant with two exchangeable converters as part of a plant-wide modernization currently underway at the facility.
 
Siemens’ project scope includes dismantling of the existing vessels, installation of two trunnion rings for the exchange-vessel system, and the engineering, supply and installation of the new converters. Siemens will also provide new motors for the converter tilting drives, upgrade the Level 1 automation system, and either renew or upgrade the electrical equipment as required.
 
Siemens must replace the converters with a minimum of interference to ongoing operations. The project must also be completed within an extremely restricted space.
 
The project is scheduled for completion in December 2008.
