Title: Vacuum consumable arc remelting electrode gap control strategies based on drop short properties

Abstract

The data presented are derived from four melts of JBK-75 (a modified A-286 alloy). The goal was to yield an electrode gap control strategy based on easily measured electrical parameters. At one current level and low pressure (<4*10/sup -3/ Torr), this goal was achieved, in that drop short period was correlated with electrode gap. However, this model was constrained by statistics which require counting 100 drop shorts. Other control strategies involving anode spikes, drop short resistance, and energy/resistance ratios were also evaluated and showed poor correlation with electrode gap. 8 refs.
