Praseodymium neodymium metal electrolytic furnace and method for prolonging furnace life
The praseodymium-neodymium metal electrolytic furnace comprises a graphite crucible, a countertop, an insulating layer, an anti-leakage layer, an inner steel sleeve, a heat preservation layer and an outer steel sleeve, and cooling treatment of a furnace opening of the electrolytic furnace is achieved. Performing insulation treatment between the deck plate and the electrolytic bath; carrying out anti-oxidation and corrosion-resistant treatment on a graphite crucible and a graphite groove; the anti-leakage protection layer is arranged between the graphite crucible and the inner steel sleeve, and the heat preservation layer is arranged between the inner steel sleeve and the outer steel sleeve, so that the service life of the electrolytic furnace is prolonged from 6 months to 26 months, and the charging cost can be reduced by 89%.
本发明公开了一种镨钕金属电解炉及延长炉龄的方法，包括石墨坩埚、台面板、绝缘层、防渗漏层、内钢套、保温层和外钢套，以实现电解炉炉口的降温处理；台面板与电解槽之间的绝缘处理；石墨坩埚石墨槽的抗氧化、耐腐蚀处理；石墨坩埚与内钢套之间采用防透漏保护层，内钢套与外钢套之间的保温层处理，使得电解炉的使用寿命从6个月延长至26个月，且装炉成本可下降89％。
