【摘要】：海绵锆自耗电极大量浸水后,采用传统常温除水工艺的除水效果不能满足核级锆合金铸锭的熔炼技术要求。结合水的"压力-温度"相图,提出加热、抽空的除水工艺,并进行了验证。该工艺避免了以往常温状态下抽空过程水分结冰,无法被彻底去除的现象,保证了海绵态物料中水分的去除效果,对工业化生产过程中因装备、操作等原因造成海绵态物料浸水后的处理具有较强的指导意义。
[Abstract]:Zirconium sponge consumable electrode mass after immersion at room temperature using the traditional water removal process in addition to the requirements of smelting technology can not meet the water effect of nuclear grade zirconium alloy ingot. The pressure temperature phase diagram, the combination of water of heating, water removal process time, and verified. This process avoids the normal temperature and time the process of water ice, can not be completely remove the phenomenon, to ensure the removal of water sponge state in the material, the industrial production process for equipment, operation and other causes has a strong guiding significance for treatment of sponge state material after immersion in water.
