摘要
使用氩气精炼ZL101A铝合金液,采用自行研制的SGJ Ι型铝液精炼效果在线检测仪检测精炼效果,获得不同冷却速度条件下的试样密度值,分析密度值数据,观察ZL101A合金试样的针孔度照片。结果表明,ZL101A试样的密度值与针孔度等级有很好的对应关系,即可以用密度值的大小反映铝合金液的含气量多少。对于ZL101A合金,用密度法可以实现炉前在线快速检测含气量。
Refining ZL101A aluminium alloys by Ar gas, checking refining effect by SGJ-Ι type instrument of aluminium alloys refining effect on-line,acquired sample densities at different cooling speed,densities data had been analysed,pinhole degree photo had been observed.The experiment shows that densities data has well corresponding to pinhole degree of ZL101A aluminium alloys, densities data can be used to show the gas of aluminium alloys, density means can be used to check the gas of ZL101A aluminium alloys on-line.
