Influence of Electrode Immersion Depth in the ESR Process: an Experimental and Numerical Study
Abstract
In the Electroslag Remelting (ESR) process, the electrode tip is plunged into the slag bath. Its immersion depth is a key parameter that has a strong influence on electromagnetic phenomena and coupled transfers within the slag. Associating trial remeltings and numerical modeling of the process, some specific impacts of electrode immersion depth are highlighted. The link between electrode immersion and slag resistance is discussed about a regime for which electrode excursion plays a specific role. The influence of electrode immersion depth on ingot solidification, especially regarding the quality of ingot skin, is addressed.
