Siemens to update LD converter

Siemens will modernise the LD (BOF) converter in the Monclova steel works.

The contract includes the engineering and delivery of key components and will be completed in the spring of 2013.

The LD converter
For the new LD converter (basic oxygen furnace, BOF) at Altos Hornos de Mexico in Monclova in the Mexican state of Coahuila, 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 compact dimensions of the suspension allow maximisation of the vessel volume – and thus the converter capacity – with respect to the space available. The tapping weight of the converter is 60 tons. Siemens is also responsible for the installation and startup supervision.
