VARIATION OF THE RESISTANCE DURING THE ELECTRODE MOVEMENT IN THE ELECTROSLAG REMELTING PROCESS

摘要

In the present paper a transient 2D Magnetohydrodynamic model is used to explore the influence of the interface movements on the resistance swing in the static mould version of the Electro-Slag- Remelting (ESR) process. The model couple efficiently the electric current distribution with the movement of the electrode, the slag/gas, and the slag/metal pool interfaces. The solid slag skin is computed with a help of a ID model that accounts for the mould current. Two electrode configurations are explored, a shallow and a 50 mm immersion depths.
