A kind of method for preparing titanium powder

Abstract

A method for preparing titanium powder relates to a method for producing metal powder, in particular a method for preparing titanium metal powder by using a dynamic hydrogenation dehydrogenation process. It is characterized in that the whole process of its preparation is carried out in a furnace body with the functions of air extraction, air filling, heating and rotation. During the preparation, the furnace is heated to 450°C to start the hydrogenation reaction in the furnace, and the furnace body is rotated so that The hydrogenated titanium layer formed on the surface of the titanium block collides with the steel ball and the titanium block, and is broken and separated until the hydrogenated sponge titanium is broken into powder; the hydrogenation and crushing process is completed, stop the rotating furnace body, and vacuumize the furnace body to make the vacuum less than 5×10-2Pa Afterwards, the temperature is raised to 600-850°C to dehydrogenate the titanium hydride powder, and finally obtain titanium powder. The method of the present invention directly carries out the processes of hydrogenation, crushing, dehydrogenation and crushing continuously in the dynamic hydrogenation dehydrogenation equipment without separating several processes independently, thereby producing high-quality and low-cost titanium powder.

Description

A method for preparing titanium powder Technical field A kind of method for preparing titanium powder, relate to a kind of production method of metal powder, especially adopt dynamic hydrodehydrogenation Process A method for preparing titanium metal powder. Background technique Titanium is the metal of excellent performance, because the production and processing technology difficulty of titanium metal is big, cost is high, has influenced its application The promotion, especially affects the application in the civilian field, and has been mainly used in the defense industry for a long time. With the scientific and technological Development, people are constantly committed to reducing the cost of titanium production, so that the application of titanium gradually penetrates into the civilian field, especially in the automotive industry. The automobile industry began to develop and use titanium metal to prepare parts to improve the quality of automobiles; other industries...

AI Technical Summary

Problems solved by technology

It has the advantages of low cost and simple process, and is suitable for industrial-scale production, but its cycle is long, the powder is broken and easily oxidized, and the dehydrogenation time is long.

Long, resulting in high oxygen content, intermittent process, high energy consumption, high production cost, difficult to prepare to meet the requirements of low-cost civil industry
