对真空原位反应合成炉的工作原理及其结构特点作了系统介绍 ,着重解决了真空冶金熔炼中加入微粉料的难题 ,采用了特殊的机械传动方式 ,利用压力差及惰性气体携带的方法将微细粉料加入熔池中并采用变频装置增强搅拌能力。该设备是真空冶金领域中的新型生产设备。 The working principle and structural features of vacuum in-situ reaction synthesis furnace were systematically introduced, and the problem of adding powder material in vacuum metallurgy melting was emphatically solved. The special mechanical transmission mode was adopted, the pressure difference and inert gas carrier Fine powder added to the pool and frequency conversion device to enhance mixing capacity. This equipment is a new type of production equipment in the field of vacuum metallurgy.
