摘　　要：工业生产海绵钛的主要方法是镁热还原法,还原蒸馏是镁热还原法生产海绵钛的主要工序之一.还原反应后反应器中主要为Ti、Mg及MgCl2的混合物,通过真空蒸馏,可以实现Ti、Mg及MgCl2的分离,得到高纯度的海绵钛.真空系统是实现真空蒸馏的关键设备,海绵钛真空蒸馏的气体负荷为真空系统泄露的空气量以及少量未冷凝的蒸发物,海绵钛蒸馏时需要真空系统的极限真空在0.01Pa以上.Magnesium reduction is the main method to produce titanium sponge in industrial,in which the reduction and distillation is one of the important processes.After the reduction reaction,the reduction product in the reactor is mainly a mixture of Ti,Mg and MgCl2.Through vacuum distillation,the separation of Ti,Mg and MgCl2.can be achieved to obtain high-purity titanium sponge.The vacuum system is the key equipment to realize vacuum distillation.The gas load of vacuum distillation of titanium sponge is the amount of air leaked from the vacuum system and a small amount of uncondensed evaporates.The ultimate vacuum of the vacuum system is above 0.01Pa.
