Paper Title:
An Analysis on Formation of ANF-6 Electroslag Fluxes Skin of Electroslag Remelting Ingot
  Abstract

The analysis on ingredient and petrographic examination of 5mm thickness ANF-6 electroslag fluxes (70% CaF2 + 30% Al2O3) skin formed during 0.45C steel 260 kg ingot remelting by electroslag remelting furnace with 160 kW, Φ100 mm × 350 mm mould indicates that the lamination phenomenon of fluxes is observed, and the Al2O3 content in fluxes skin near mould side and near electroslag ingot side is higher 69.24%-75.62%, and the CaF2 content is 21.46%-28.36%, where at skin center 3 mm location, the Al2O3 content in fluxes skin is only 15.84% and the CaF2 content is 81.06%. The solidification mechanism of “ring shaped miniature fluxes pool” formed at upper edge of remelted ingot is advanced in this paper, and the surface quality of ingot by using large over-cooling and low melting-point fluxes is higher than that by using low over-cooling and high melting-point fluxes.
