Abstract

As the request for quality steel and stainless steel is rising throughout the industry and as the added values through vacuum treated steels is increased, the number of installed and contracted vacuum plants for the improvement of the steel quality is getting higher and higher. Nowadays, vacuum treatment facilities are not only to be installed in integrated and stainless steel plants, but also approx. half of the so-called minimills are built worldwide with mostly tank degassers. In this paper, we would like to take a look on the design as well the operational results of our latest commissioned vacuum plants like the VTD’s at SSAB/US and Uralstal/Russia, the VOD’s at Dongbei Steel/China and TISCO/China, whereas the Tisco plant is the biggest VOD worldwide, and also the RH’s at CSA/Brasil and Tisco/China. An outlook will be given on the future of the vacuum treatment philosophy which is arising of the market trends.
