SMS Demag to Provide Steelworks, CSP Plant for Tata Steel
02/26/2008 - Tata Iron & Steel awards order to SMS Demag to supply an X-Melt converter meltshop and a CSP plant.
Tata Iron & Steel Co. Ltd., India, has awarded SMS Demag an order to supply an X-Melt® converter meltshop and a CSP® plant. The contract is part of the "Tata Growth Plan," by which Tata Steel will expand its production at the Jamshedpur works in eastern India on a step-by-step basis to 10 million tonnes/year.
Supply for the X-Melt steelworks includes two converter vessels as well as the gear units, which include pneumatic emergency drive, lance equipment and the converter lining facilities. Each of the two converter vessels will have a maximum tapping volume of 170 tonnes of liquid steel, and both vessels together will have a nominal annual production of 2.8 million tonnes. The vessels will be equipped with SMS Demag’s maintenance-free lamella suspension technology.
Primary exhaust gas systems for the two new converters will operate according to the proven "Baumco system." The system uses wet cleaning, and the resulting fumes are re-used to improve energy efficiency. On the secondary side, two electrostatic precipitator units will provide dedusting.
Tata’s new CSP plant will be rated for an annual capacity of 2.4 million tonnes of hot strip, 900 to 1680 mm wide and 1.0 to 20.0 mm thick. Depending on the requirements of the process and the final product, the slab thickness can be continuously adjusted in ranges of 50 to 70 mm and 70 to 90 mm.
The CSP plant will comprise two vertical bending machines, two roller-hearth soaking furnaces with swivel ferry, a six-stand rolling mill, laminar strip cooling section, and two downcoilers. The plant will accommodate the addition of a seventh finishing stand and a third coiler at a later stage.
Tata Steel intends to use the CSP plant to focus on high-grade products. In addition to carbon steels, the product mix will include non-grain-oriented electrical steel strip, pipe grades, and dual-phase steels.
SMS Demag’s scope of supply for the project includes the mechanical equipment and the X-Pact® electrical and automation systems. For the X-Pact electrical equipment and automation system for the X-Melt steelworks and for the CSP plant, SMS Demag will also supply the electric drive systems, basic automation system (including visualization system), technological control systems, and process models. SMS Demag will test and optimize the entire automation system under near-operating conditions using the Plug & Work concept, thus substantially reducing the commissioning phase.
Commissioning of the plants is scheduled for the end of 2010.
This order follows Tat Steel’s 2007 award of contracts to SMS Demag for modernization of its existing hot strip mill in Jamshedpur and for construction of a new oxygen steelworks with continuous slab caster at the Kalinganagar works.
Tata Iron & Steel Co. is the sixth-largest steelmaker in the world.
SMS group is, under the holding SMS GmbH, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It consists of the two Business Areas SMS Demag and SMS Meer, which jointly form SMS metallurgy. In 2006, some 9000 employees worldwide generated a turnover of about EUR 2.8 billion.
