Abstract:To explore the influence of ambient pressure and gas composition on the results in the atomization process of SmFe melt,atomization and nitrogen quenching process of liquid SmFe alloy with high pressure was simulated using Fluent based on the close-coupled nozzle.Simulation results show that high ambient pressure can obviously improve the atomization effect and the minimum ambient pressure is 3.0 MPa when the atomization effect is relative ideal using pure N2 as atomized gas;mix Ar to N2 can reduce the ambient pressure needed for the atomization,but too much Ar can cause an adverse impact on the spray cooling and melt nitriding;in summary,when N2 content at 25% and the ambient pressure is 2.0 MPa,atomizing effect gets its maxima.
