摘要

针对雾化器效果不明显等问题

采用对气流加热从而影响金属雾化的方法来提高雾化效果。结果表明

通过加热雾化气流可以有效减小晶粒的尺寸

表明加热气流是一种有效提高雾化效果的方法。对气瓶至雾化器的气流管道设置了加热装置

并对加热效果进行了模拟。结果表明

随着气流的流动

气体温度、速度均提高

在管道末端的气体速度、温度之间近似符合关系式:V=0.32T+155.4。

Abstract

Aiming at the low efficiency of atomizer

gas flow was heated to improve atomization effects of liquid metal. The results reveal that through heating atomized gas flow

grain size in the liquid metal can be decreased greatly

which shows it is a effective way to improve atomizing effects by heating gas flow. Heating apparatus was set at gas channel of gas bottle to atomizer

and heating effects were simulated. The results indicate that with increasing in flow velocity

gas temperature and gas velocity are the function of temperature of channel end:V=0.32T+155.4.
