As liquid steel could occasionally escape out of control, the use of the LiquiRob has made the casting work significantly safer. It is no longer necessary to enter the hazardous area. Moreover, heavier and more efficient lances can now be used. This significantly increases the success rate of the first lancing attempt.
Deutsche Edelstahlwerke GmbH is part of the Schmolz + Bickenbach Group and is one of the leading companies in the production and processing of stainless-steel long products. Some 4,000 employees work in the Witten, Siegen, Krefeld, Hagen and Hattingen plants, where they produce and process around 1 million metric t of stainless steel per annum. In the Siegen plant, the steel is produced in an electric arc furnace and cast on a six-strand caster into billets with diameters ranging from 138–265 mm.
Primetals Technologies developed LiquiRob specifically to improve occupational safety and the quality of measurement under the severe operating conditions encountered in the iron and steel industry. At the moment, six systems are working in continuous casting plants around the world, plus one on an electric arc furnace and another on a converter.
