摘要：
Abstract: A thermal model is developed for the ingot solidification during vacuum arc remelting (VAR) and is applied to calculate pool profiles for a VT3-1 alloy. The pool profiles are calculated for two remelting schedules, and the calculation results are compared with radiography data. The model calculation results are shown to agree satisfactorily with experimental data. The model is used in practice to develop conditions for the final remelting of a VT3-1 alloy to exclude the formation of segregation defects, namely, β flakes and macrosegregation. The developed model can be used for technological calculations and can give important information on the dynamics of VAR ingot solidification. © 2018, Pleiades Publishing, Ltd.
