本文对单电源、双回路导电模电渣重熔（ESR-STCCM）工艺进行了物理模拟。采用木材合金和氯化钠溶液研究了过流电极和载流模导电部分（导体）的电流分配比。作为比较，研究了常规ESR（CESR）工艺。ESR-STCCM工艺的总电流大于CESR工艺，表明ESR-STCCM工艺的电阻小于CESR工艺。结果表明，I电极/I导体比随填充率、电极浸入深度和有效导体高度的变化而变化。电极浸入深度对电流分配比起着重要作用。有效导体高度对电流分配比的影响不大。较大的填充率对ESR-STCCM的电流分配比有明显的影响。在一定填充率下，电极电流随电极浸入深度的增加而增加。所建立的物理模型对真实的ESR-STCCM具有重要的指导意义。
Physical simulation of a single-power, two-circuit electroslag remelting (ESR) process with current conductive mold (ESR-STCCM) is carried out in this paper. Wood alloy and sodium chloride solution are used to study the current distribution ratio of passing electrode and conductive part of current carrying mold (conductor). A conventional ESR (CESR) process has been studied as a comparison. The total current of ESR-STCCM is larger than the CESR process, which indicates that the resistance in ESR-STCCM is smaller than in CESR. Results show that the ratio ofIelectrode/Iconductorchanges with filling ratio, electrode immersion depth, and effective conductor height. Electrode immersion depth plays an important role on the current distribution ratio. Nevertheless, the effective conductor height has a little influence on the current distribution ratio. A larger filling ratio has an obvious effect on the current distribution ratio in ESR-STCCM. Current flowing through the electrode increases with the increasing of electrode immersion depth under a certain filling ratio. The physical model established can provide an important direction to real ESR-STCCM.
