Abstract

The invention provides a gas jet gas cooling type superfine titanium alloy atomization device and a gas jet gas cooling type spraying disk. The atomization device comprises a vacuum bin, a melting furnace, a gas jet gas cooling type spraying disk and an atomization tube, wherein a vertical through hole is arranged in the middle of the spraying disk, only one circle of alternatively distributed inclined holes are arranged around the through hole, one Laval nozzle of the same parameter is arranged in each inclined hole, the inclined angle between the extension line of the lower end of each Laval nozzle and the extension line of the lower end of the through hole is 28-30 degrees. The gas jet gas cooling technology is adopted, so as to effectively reduce the risk in increase of the content of oxygen in micro powder caused by water cooling. Integration of atomization, anti-reverse and cooling function is achieved, the Mach number is adjusted to be 4.1-4.9, the problems of titanium alloy such as atomization, cooling and anti-reverse are simultaneously solved in 0.1 second; only one circle of the Laval nozzles are arranged on the spraying disk, so as to effectively reduce the complex degree of the spraying disk structure, facilitate accuracy of the flow field control and simultaneously save the energy source.

Description

technical field [0001] The invention relates to a production equipment for ultrafine atomization and cooling of titanium alloy (including 99.999% high-purity titanium). Background technique [0002] High-purity titanium and titanium alloy ultra-fine materials are increasingly widely used in aerospace, electronic grid and clean energy fields, especially its low density, high strength, and corrosion resistance, which are close to human bone density (non-toxic). Medicine can be used for artificial joints, partial human implantation (cardiac pacemaker), etc. For this reason, a large number of titanium alloy micropowders with an average particle size of 10 microns to 35 microns, an oxygen increment of less than 100PPM, and a spherical rate of about 90% are required. At present, the direct yield of titanium alloy micropowder produced by most domestic and foreign equipment is about 30%, and the output is generally less than 5kg / min, which is difficult to meet the market demand. ...
