抚顺铝厂科研所继成功地进行62000安自焙槽干法启动后,又于1984年7月在135千安中间下料预焙槽上进行了干法二次启动的尝试并获得成功。此次干法二次启动,装炉方式与以往相同(即先注入铝水,后装填启动槽物料),焙烧历经88小时,采用无效应启动。干法启动的实践说明:1.大型预焙电解槽焙烧阶段,调整各阳极组的 Fushun Aluminum Research Institute successfully carried out 62000A self-baking trough dry start, and in July 1984 in the middle of 135Kan pre-baked trough pre-baking trial and attempt to dry the second success. The dry start the second time, loading furnace the same way as in the past (that is, first injection of aluminum, after filling the starting tank material), roasting after 88 hours, the use of ineffective start. The practice of dry start instructions: 1. Large pre-baked cell roasting phase, adjust the anode group
