06/07/2011 - Siemens VAI Metals Technologies won an order from stainless steel producer Viraj Profiles Ltd. to supply an AOD (argon-oxygen decarburization) converter for its plant located in Tarapur, Maharashtra, India. The project is scheduled for completion by mid-2011.

Siemens VAI Metals Technologies won an order from stainless steel producer Viraj Profiles Ltd. to supply an AOD (argon-oxygen decarburization) converter for its plant located in Tarapur, Maharashtra, India. The project is scheduled to be completed by mid-2011.
 
Viraj Profiles is currently implementing a large-scale program to expand its production capacities. As part of this program, Siemens VAI already received an order to supply a rolling mill for stainless steel bar and light sections (180,000 tonnes per annum). The new AOD converter will have a capacity of 245,000 tonnes of liquid steel per year, enabling Viraj Profiles to increase the volume and efficiency of stainless steel billet and bloom production in Tarapur. It will then be able to supply most of the new and existing rolling mills with billets from its own production, according to Siemens VAI.
 
Siemens VAI will be responsible for the engineering of the AOD converter, which will have a tapping weight of 55 tonnes. It will also supply core components, including the trunnion ring, tilting drive, valve station, rotating inlet, injection nozzles, top lance, and a combined lance and extraction hood carriage. Features of the plant include the suspension system, a traversing extraction hood and top lance, as well as individual nozzle control.
 
The order also includes the Level-2 automation system for the converter tilt drive, the blowing lance, and the bottom blowing system. Siemens VAI will supply the process automation, including the Simetal AOD optimization system and the steel expert process models.
 
Siemens Ltd. India will handle some of the local manufacturing for the project. This includes supplying the trunnion ring and parts of the basic automation system for the AOD converter as well as supervising installation and commissioning.
 
Viraj Profiles Ltd. is India's largest producer of stainless steel long products.
