Titanium alloy smelting atomization powder manufacturing equipment and manufacturing technology thereof

Abstract

The invention discloses titanium alloy smelting atomization powder manufacturing equipment and a manufacturing technology thereof. The titanium alloy smelting atomization powder manufacturing equipment comprises a crucible body (1); a smelting cavity (1.1) is formed in the crucible body (1); a pouring hole (1.2) through which smelted titanium alloy liquid flows out is formed in the lower end of the crucible body (1); a heating mechanism (2) is arranged at the lower part of the crucible body (1); the heating mechanism (2) comprises a heating pipe (2.1), an auxiliary heating coil (2.2) and a water cooled hood (2.3); the heating pipe (2.1) is arranged at the lower part of the pouring hole (1.2); the auxiliary heating coil (2.2) sleeves the heating pipe (2.1); the water cooled hood (2.3) sleeves the auxiliary heating coil (2.2). The titanium alloy smelting atomization powder manufacturing equipment and the manufacturing technology have the advantages that kish in the crucible body is little, the probability of blocking is low, the liquidity of titanium alloy liquid flowing from the smelting cavity to an atomization cavity is good and the titanium alloy liquid is not prone to being interrupted, and the atomization powder manufacturing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a titanium alloy smelting atomization powder making equipment and a preparation process. Background technique [0002] Spherical titanium and titanium alloy powders are important basic raw materials for high-performance powder metallurgy titanium and titanium alloy forming and processing because of their good fluidity, less pore inclusions, and low impurity content. Widely used in aviation engine parts, supercharged TiAl turbines for automobiles, titanium alloy products for medical implants, etc., and new rapid prototyping equipment and technology represented by 3D printing technology (laser rapid manufacturing, electron beam selective melting technology ) have doubled the demand for spherical titanium and titanium alloy powder. [0003] Spherical titanium and titanium alloy powders prepared by vacuum induction melting and gas atomization have the advantages of high pu...

AI Technical Summary

Problems solved by technology

The smelted titanium alloy liquid is exported from the melting chamber to the atomization chamber through the heating tube. During the export process, the liquid is easy to solidify in the heating hole of the heating tube, so that the amount of titanium alloy liquid exported to the atomization chamber is reduced or even blocked. Heating holes affect the milling efficiency
