Symposium Liquid Metal Processing & Casting
Presentation Title Experimental Study on Alloying Additions in Electro Slag Refining
Author(s) Harald Scholz, Thomas Kilzer, Gerhard Brückmann, Henrik Franz
On-Site Speaker (Planned) Harald Scholz
Abstract Scope Electro Slag Refining can be carried out under vacuum, atmospheric or elevated pressure using atmospheric composition or inert gas. Process parameters like electrode sizes, slag systems and the working pressure can be adapted to the necessities of the process to influence the final ingot quality. In pressure ESR gases like Nitrogen can be easily added to the final ingot via feeding of nitrogen containing elements and decreasing the immersion of the electrode in slag. In addition the slag can be de-oxidized to maintain the refining capability of the slag. As a next step the alloying of certain elements during ESR can be done considering the melting temperature of slag. A feasibility analysis was carried out allowing the addition of vanadium oxide and de-oxidation agent at the same time during the ESR process in order to increase the vanadium content in the final ingot.
