Paper Title:
Research on the Surface Quality of ESR Large Slab Ingots
  Abstract

A special bifilar 40t electroslag remelting(ESR) furnace for slab products has been fabricated to produce heavy plates for special application. The ESR slabs with the maximum thickness of the world in size of 980 mm thickness, 2000 mm wideness and 2800 mm length have been produced successfully. However, the ingots surface quality is a serious problemn in ESR process for large slab ingots, for ingot and mold with a relatively mobile, larger ingot contraction and thicker slag skin. Using CaF2-CaO-Al2O3-SiO2-MgO slag, suited remelting rate, lower filling ration, smooth movement of mold and adjusting taper of the mold and are necessary for improving surface quality of the ESR large slab ingots.
