摘要
本文介绍了铝合金用熔剂的组成部分及其作用,以Na3AlF6、K2SiF6、RECO3、K2SO4的质量百分比为可变因素,以等摩尔的NaClKCl作为熔剂的基体,采用正交试验设计,选用正交表L9(34)进行试验,以K模作为熔体纯净度的检测方法,最终确定了熔剂的最佳配方。使用该最佳配方熔剂精炼后的A356.2合金纯净度可达到A级标准。
In this paper,the component and its action of flux used in Aluminum alloy was introduced. The weight percent of Na3AlF6, K2SiF6, RECO3, K2SO4 was taken as variable factor, equimolar KCl and NaCl was taken as matrix, K mold was taken as test method, the orthogonal experimental design method was adopted and L9 （34） table was chosen for the experiment, an optimal flux was obtained. The cleanliness of A356.2 Aluminum alloy which was refined with the optimal flux could achieve grade A.
