进行了一项研究，以确定电极间隙对真空自耗电弧重熔过程中熔滴短路性能的影响。这项工作的目标是产生一种基于易于测量的电参数的电极间隙控制策略。对于特定合金，在单一电流水平和低压（<4 X 10-3 Torr）下，实现了这一目标，因为发现下降短周期与电极间隙高度相关。然而，我们发现该模型受到统计数据的限制，统计数据需要计算 100 个跌落短路才能获得有效的测量结果。还评估了涉及阳极尖峰、下降短路电阻和能量/电阻比的其他控制策略，这些特性与电极间隙的相关性较差。
An investigation was conducted to determine the influence of electrode gap on the properties of drop shorts during vacuum consumable arc remelting. The goal of this work was to yield an electrode gap control strategy based on easily measured electrical parameters. For a particular alloy, at one current level and low pressure (<4 X 10-3 Torr), this goal was achieved, in that drop short period was found to be highly correlated with electrode gap. However, this model was found to be constrained by statistics which require counting 100 drop shorts in order to obtain a valid measurement. Other control strategies involving anode spikes, drop short resistance, and energy/resistance ratios were also evaluated and these properties showed poor correlation with electrode gap.
