Vol. 25 No.4 Apr. 2004 FOUNDRY TECHNOLOGY # 269 # ZL101A 金 光, 赵忠兴, 王松涛 ( , 110168) : 使用氩气精炼ZL101A 铝合金液, 采用自行研制的 GJ-) 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 条件下的试样密 值, 分析密 值数据, 观察ZL 101A 合金试样的针孔 照片结果表明, ZL101A 试样的密 值与针孔 等 级有很好的对应关系, 即可以用密 值的大小反映铝合金液的含气量多少对于ZL 101A 合金, 用密 法可以实现炉前在线 快速检测含气量 : 铝合金; 精炼; 密 + : TG292 TG 146. 2 1 : A : 1000-8365( 2004) 04-0269- 03 Application of Density Method about Checking ZL101A Aluminium Alloys Refining Effect on-line JIN Guang, ZHAO Zhong-xing, WANG ong-tao ( henyang Institute of Techonlogy, henyang 110168, China) Abstract: Refining ZL 101A aluminium alloys by Ar gas, checking refining effect by GJ-) 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. T he experiment show s that densities data has well corresponding to pinhole degree of ZL 101A aluminium alloys, densities data can be used to show the gas of aluminium alloys, density means can be used to check the gas of ZL 101A aluminium alloys on-line.
