EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

After years of meltshop trials, the final technical solution for a Mechanical Pumping System for Vacuum treatment in Steelmaking has been finalized by SMS group and the pump manufacturing company Flowserve/SiHi. The result of trials and validation processes of the technology are presented in this paper outlining the optimal solution for a series of installations for specific technical demands. Existing steam ejector revamping, small VTD, HI-dust production process such as VOD or VD-OB or RH-OB, limited space layouts and ATEX requirements are all challenges that are well answered by this innovative solution: a game changer and a technological step ahead.
