Abstract: The distribution of magnetic field and joule heating in the electroslag remelting process, including electrode, slag and ingot, were obtained by finite element software. The changes in the temperature profiles, the velocity fields and the magnetic fields with different inserting depth of electrode were analyzed in the electroslag remelting process coupling the magnetic field and joule heating. The results show that when the inserting depth is 15mm, an intermediate region appears between the anti-clockwise circulation eddies in the bulk of the slag which is controlled by a clockwise circulation eddy. Its size increases with the increase of electrode inserting depth. The turbulent kinetic energy drops by 21% and the maximum temperature decreases about 1% for each additional 15mm of the inserting depth.

Key words: electroslag remelting, three dimensional numerical simulation, electrode inserting depth, shape of metal pool, electro-magnetic fluid
