Raw material selection: The selection of grade 1 or above sponge titanium, oxygen content is less than 500ppm, vacuum consumable electric arc furnace melting 3 times, to ensure uniform product composition, no segregation.

Production process: Titanium sponge - three times melting - forging - rolling titanium rod - CNC machining - ultrasonic detection - surface detection - packaging.

Testing items: ultrasonic flaw detection, chemical composition and other items.

Powder production principle: 3D printing metal powder as the most important part of the metal parts 3D printing industry chain, is also the greatest value. The method of preparing spherical titanium and titanium alloy powder for 3D printing by rotating electrode solves the technical problems of difficult and costly preparation of ultra-fine titanium and titanium alloy powder by prior art. The titanium rod or titanium alloy rod is put into the arc melting rotating atomization device, the vacuum degree of the control device is 0.6Pa and the inert gas protection, the DC plasma torch is opened, and the titanium rod or titanium alloy rod is melted into liquid drops; Controlling the rotating electrode speed, the droplets are broken into fine particles through centrifugal force to obtain spherical titanium powder or titanium alloy powder for 3D printing. This method combines the arc melting system and the rotating electrode system, the production efficiency of spherical titanium and titanium alloy powder is high, the energy consumption is low, the resulting product has good sphericity, low oxygen content, good fluidity, and is a good raw material for 3D printing.

Application: The outstanding advantages of laser 3D printing technology in the direct forming of large complex titanium alloy structural parts and its broad application prospects in the development and production of aircraft equipment make the industrial application of 3D printing of high-performance titanium alloy structural parts also develop rapidly. The market demand for raw material powder has also increased.
