Optimization of Technological Parameters in Multi-stream Gas Atomization AITranslate
Abstract AITranslate
Through orthogonal experiment,systematic study is made of the influence of upper bed/lower-bed gas temperature,metallic melt temperature and catheter projecting height on the average particle size and particle distribution of the powder prepared by multi-stream gas atomization. Through visual analysis and variance analysis, the extent of influence of various parameters was evaluated, and the parameters were op- timized. The results of the experiment showed that the optimum technological parameters are as follows： the pressure of the upper atomizer and the lower atomizer is 0.7 MPa and 0.4 MPa respectively,the tem- perature of molten metal is 350 ℃,and the projecting length of the catheter was 4mm,the mean particle size was 6.3 μm and 77.3 % of the powder has particle size〈10 μm. And the firsl wave crest value in the size distribution curve is about 500nm,which is an order of magnitude smaller than that as reported.
