Features of slag-metal interaction at electroslag remelting of heavy ingot

摘要：

The new look on the ESR process allows us to formulate physic-chemical model of process based on equilibrium thermodynamic principles. Using this model we have compared the refining ability and oxidizing action of fluoride and two oxide-fluoride slags in argon atmosphere and in the air. It has been indicated that even if the protective atmosphere is used, slags are still able to oxidize the metal, and the extent of desulphuration is determined by the content of CaO in the slag.
