Abstract

The difference in metallurgical quality of C-HRA-3 alloy smelting using two kinds of slag system was investigated by 10 kg electroslag remelting furnace. The results show that the alloy electroslag ingot smelting by a new-type 50% CaF2-26% Al2O3-20% CaO-3% MgO basic slag system has better surface quality compared to 60% CaF2-20% Al2O3-10% CaO-10% MgO basic slag system. The columnar crystal growth direction of the electroslag ingot, smelting by new-type slag system, has a smaller angle with the centerline, and the depth of the molten pool is greater. The content of Al, Ti, Zr, Si, and B at various positions of two electroslag ingots smelting with the same proportion of TiO2 and ZrO2 components can be controlled within the target content range of C-HRA-3 alloy. There are fewer inclusions in the electroslag ingot smelting by new-type slag system, and the proportion of oxide inclusions at four different ingot heights is lower.
