Abstract

The invention discloses an induction plasma heating spheroidization powder supply component which comprises a powder supply pipe (1), a sealing ring (2), a heater base (3) and a plasma heater (4); andthe powder supply pipe (1) is sequentially connected with the heater base (3) and the plasma heater (4). By adopting the induction plasma heating spheroidization powder supply component, the sealingring (2) performs sealing, a sealing component (101) in the powder supply pipe (1) performs water injection, and an interval layer formed by a powder supply outer pipe (102) and a powder supply innerpipe (104) realizes refluxing of cooling water, so that continuous cooling and temperature control in the powder supply process of the powder supply pipe (1) are ensured, the problem that the powder supply pipe (1) component is easily burnt is solved, the reliability is high, and the stability is good.

Description

technical field [0001] The invention relates to an induction plasma heating spheroidization powder supply assembly, which belongs to the application field of heating technology. Background technique [0002] The development of induction plasma heating spheroidization technology is closely related to the current rapid development of 3D printing rapid prototyping technology and the development of powder spraying, porous material preparation and other technologies. The performance requirements are high, and the powders prepared by the traditional atomization method, carbonyl method, sol-gel method and other spherical powder preparation methods have problems such as wide particle size range, easy powder bonding, and low spheroidization ratio, which are difficult to meet the above technologies. powder requirements. Compared with traditional methods, thermal plasma powder spheroidization has unparalleled advantages, especially the technology of high-frequency induction plasma pre...
