Melting and casting rare earth alloy with water cold copper crucible

Abstract From the concept of the crucible in FeSi electric furnace, the paper considers that periodically destroying the crucible is the key to improve air permeability, reduce burden sintering and keep normal furnace condition.

从硅铁电炉炉内坩埚的概念出发，认为周期性地破坏坩埚是改善炉料透气性，减轻炉内结料，保持正常炉况的关键。
