等离子体技术在冶炼和铸造生产中的应用

Application of Plasma Technology in Smelting and Foundry Production

等离子冶炼具有一系列特点,能够加快热传导、物质交换和化学反应过程,从而强化冶炼过程;能够与其它冶炼手段配合使用,形成等离子电渣工艺、等离子感应重熔工艺等;在冶炼难熔金属、培养难熔金属单晶体、精炼活泼金属、回收利用贵重金属等方面,具有难以替代的作用。

Plasma smelting has a series of features which can accelerate heat transfer,material exchange and chemical reaction processes,thus strengthening smelting process.It can be used together with other smelting methods to form plasma electroslag process,plasma induction remelting process,etc.It has an irreplaceable role in the smelting of refractory metals,the cultivation of refractory metal single crystals,the refining of active metals,and the recycling of precious metals.
