Numerical Simulation on Saffman Force Controlled Inclusions Removal during the ESR Process
Metals, 2020 Electroslag remelting (ESR) is an effective method for removing nonmetallic inclusions from steels or alloys. The main stage of inclusion removal during ESR is the aggregation of liquid metal film (LMF) to form droplets at the consumable electrode tip ...
