Siemens Updates LD Converter at AHMSA's Monclova Works
Feb. 3, 2012 Siemens VAI Metals Technologies received an order from Altos Hornos de Mexico, S.A.B. de C.V. (AHMSA) to modernize the LD converter in the Monclova steelworks in the Mexican state of Coahuila. The contract is scheduled for completion in the spring of 2013.
For the new LD converter (basic oxygen furnace), Siemens is carrying out the engineering and delivery for key components such as the furnace vessel, the trunnion ring, and the maintenance-free Simetal Vaicon Compact Link suspension. The tapping weight of the converter is 60 tons. Siemens is also responsible for the installation and startup supervision.
In the past several years, Siemens has received a series of orders from AHMSA, including a contract in 2007 for the expansion of the metallurgical plant and heavy plate rolling mill, in 2009 for the delivery of hot-rolling-mill equipment with new basic and process automation, and in 2010 for the delivery of the third LD (Converter No.1) converter. Converter No.2 started operation in March 2007, and converter No.3 started operation by the end of 2011.
