Abstract
Effect of melting variables on the slag-metal reactions in electro-slag-remelting process (ESR) was studied using several manganese bearing steel electrode wires and CaO-SiO2-CaF2 system fluxes. Main results obtained are as follows:1 The temperature distribution in the molten slag and metal pool was measured. The temperature of salg was the highest in the middle part between electrode tip and molten metal pool.2 The temperature of slag rose with the increase of melting voltage.3 Electrode tip to liquid metal surface distance was affected by melting voltage and flux weight. 4 Mn, Si and O content of ingot were considerably affected by melting voltage and flux weight.5 Using the results obtained, some slag-metal reactions were discussed.
