The parameter optimization strategy of atomizer is studied regarding the large porosity of spray forming ingot blanks.Based on the influence of the atomizer parameters on the airflow field,the state change of the droplet is controlled to reduce the porosity of the ingot blank.According to different topangles,nozzle diameters and atomizing gas pressures of the atomizer,the changes of the airflow field are analyzed,the influence law of these three parameters on the airflow field is obtained,and injection molding experiments are carried out.The results show that after the optimization of the atomizer parameters,the atomization effect of the droplets is significantly improved,and the pores of the aluminum alloy ingot billet prepared by the optimized atomizer parameters are smaller.
