铝合金精炼处理工艺研究

Study on Degassing Technology of Al Alloys

对铝合金精炼处理工艺进行了研究。结果表明,采用 25%Na2SiF6 +75%C2Cl6 具有较好的精炼效果,在加入量为0.6%时效果最佳;用新设计的除气钟罩及旋转转子除气机,可以获得好的精炼净化效果,相比之下,旋转转子除气机效果最佳。

The degassing technology of Al alloys was studied.The results show that a good degassing effect can be obtained using 25%Na_2SiF_6+75%C_2C1_6 with 0.6% adding content; a better result can be gained using new designed degassing plunger and spinning rotor degassing machine.
