Production of flat ingots-slabs in electron beam units with an intermediate crubile

摘要

A mathematical model was plotted of thermal processes in solidification of flat ingots-slabs in electron beam melting with an intermediate crucible (EBMIC) and portion feed of liquid metal. Optimal technological modes and parameters of melting have been calculated. EBMIC technology with portion solidification was used to produce experimental flat slabs-ingots of AK-25 and AK-33 steels. The high quality of the produced ingots is demonstrated.
