Siemens to increase caster capacity and product range at Nizhny Tagil, Russia--Highquality semis for a wide range of industrial applications

摘要

Siemens VAI Metals Technologies received an order from the Russian steel producer Nizhny Tagil Iron & Steel Works (NTMK) to increase the casting capability of the existing two-strand beam-blank/bloom combi-casterCCM3,. The project scope includes the supply of engineering, equipment and systems, installation work and all required modification activities to enable the caster to cast up to four bloom strands in total to meet the increased market demands for rail steel. In the bloom-casting mode, machine capacity will be increased from 700,000 t/a to 1,000,000 t/a. The order value is just under 30 million euros. Startup of the modified caster is scheduled for November 2010. In connection with a modernization campaign underway at NTMK, three of the LD (BOF) converters were already replaced by Siemens VAI and a fourth 160-ton-capacity converter is now being installed. With consideration to the higher steel production rate, the output of the continuous casting facilities also has to be increased. To this end, Siemens VAI will expand the casting capacity of the two-strand beam-blank/bloom combi-caster CCM3, originally supplied by Siemens VAI, which currently casts beam blanks in 395 mm (height) x 165 mm (web thickness) x 530 mm (width) formats, or blooms with a thickness of 200 mm and a width of 550 mm.
