Thickness

uniformity and mechanical properties of slag skin are main factors to influence the surface quality of continuous withdrawing electroslag remelting ( ESR) ingot. Thin and homogeneous slag skin is a kev to get ni(*e surface quality of ESR continuous casting ingot. The effect of current density distribution in slag bath

heat transferring conditions near mold wall

slag ingredient and factors to influence the change of temperature in "high-temperature region" on thickness of slag skin are analyzed in this paper. Production test results showed that thin and homogeneous slag skin with ensuring to satisfy long slag form and appropriate mechanical properties at high temperature was obtained by controlling operating temperature and slag ingredient in order to get nice surface quality of ESR continuous casting ingot.
