The DH-recirculation process, which utilized a vacuum vessel with one snorkel tube, belonged to the older generation of vacuum degassing processes. By the mid-1980s, this process had been replaced completely by the more efficient RH recirculation degassing process, a vacuum vessel with two snorkel tubes. A growing number of producers are converting their old single-snorkel DH facilities into modern and more efficient RH facilities with a relatively small investment outlay. |
OEMK operated two DH (Dortmund Hörde) single-snorkel recirculation degassing plants, which had been supplied by SMS Mevac at the beginning of the 1980s. For the most recent project, SMS Mevac revamped one of the existing DH facilities into an RH (Ruhrstahl-Heraeus) facility.
SMS Mevac’s scope of supply essentially comprised two new RH vessel bottom sections with snorkel tubes, the inert gas system for the steel circulation, snorkel-tube maintenance equipment, special refractory material, control systems and instrumentation, basic engineering for further modernization measures, and supervision of erection and commissioning.
The Stary Oskol electric steelworks primarily produces bearing and spring steel grades, special pipe grades and rail steel grades and is therefore dependant on powerful secondary steelmaking.
SMS Mevac GmbH forms part of the Metallurgical Plant and Rolling Mill Technology Business Area of the SMS group, an internationally active in plant construction and mechanical engineering relating to the processing of steel, non-ferrous metals and plastics. The group is divided into the Business Areas of Metallurgical Plant and Rolling Mill Technology, Tube, Long Product and Forging Technology and Plastics Technology. In the year 2003 around 9500 employees worldwide generated a turnover of around EUR 2.20 billion.
