The metallurgical combine of Novolipetsk (NLMK), located in Lipetsk, Russia, has successfully commissioned the RH-TOP plant supplied by SMS Mevac, Germany.
The new duplex RH-TOP plant will be used predominantly for the production of ultra-low-carbon steels and low-alloy grades, among others, for the production of pipes and tubes and for shipbuilding. The company plans to treat more than 4 million tonnes per year of steel in the RH plant.
The duplex plant, designed to treat heats with a nominal weight of 320 tonnes, is equipped with a high-efficiency vacuum pump system.
Both treatment stations use a hydraulic rocker-type system for lowering the snorkels into the steel bath. The plant is completed by devices such as TOP lances, a common alloying system with double-chamber vacuum locks, and temperature measuring and sampling devices with slag breakers. The supplied plants also include two stations for additional treatments. Each station is equipped with a cored-wire feeding system, devices for insulating powder addition, and sample taking for hydrogen measurements.
The scope of supply comprised the complete basic engineering, delivery of main equipment, complete basic automation and level-2 process automation systems, and supervision of installation and commissioning.
SMS Mevac GmbH forms part of the Metallurgical Plant and Rolling Mill Technology Business Area of the SMS group, which, under the roof of the SMS Holding GmbH, consists of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. With about 11,000 employees, the group generates sales of over EUR 3 billion.
