Development and Application of Large Continuous Hydrogenation and Dehydrogenation Equipment for Preparing High-Purity Ti Powder

Restricted by the dual factors of process and equipment,the current domestically produced Ti powder is generally low in quality due to its high oxygen content and cannot be used in mainstream high-end manufacturing fields.In order to meet the urgent needs of domestic manufacturers for mass production of high-quality Ti powder with low oxygen content,NAURA has developed the first domestic large continuous equipment which uses the HDH method to produce high-quality Ti powder.The equipment is composed of multiple process chambers in series according to the work process,and Ti powder is transported to each process chamber by the roller bottom boat for corresponding process treatment.The equipment can automatically run according to the preset production cycle,and the continuous production is uninterrupted.During the actual application test,the equipment is stable and reliable,because it can ensure that all production processes are in a high vacuum environment or high purity argon protection,the oxygen content of the ultra-fine Ti powder with particle size less than 44μm can be stably controlled below 0.12%,it has fully reached the requirements of the highest grade level TF-0 in the powder metallurgy industry Ti powder standard of China.
