The paper describes the possible slag losses in electroslag remelting. The amount of losses for skull formation of different thickness (1, 3, 5, 10 mm) was evaluated in remelting of large-sized ingot using slags ANF-39 and ANF-28. Changes in component composition of gas-slag-metal system, which were caused by decrease in slag mass for skull formation and in case of compensation of these losses, are considered. The effect of changes in slag amount on technological parameters of melting was investigated. Ref. 17, Tables 5, Figures 5.
Keywords: electroslag remelting; slag skull; slag losses, slag properties; gas–slag–metal system
