许多铝合金中都添加一定量的Zr，但常用的加Zr方式都存在着一些弊端．为此，研制出了新型Zr添加剂和加Zr新工艺．这种Zr添加剂制作简单，含量准确，使用方便。经试验及生产证实，采用该种添加剂向铝合金中加Zr，加入方法简单，加Zr温度可降低到720～74℃，Zr的实收率达80％以上，而且还可达到改善铸锭内部冶金质量的目的。 A lot of aluminum alloy to add a certain amount of Zr, but the common method of adding Zr there are some drawbacks. To this end, developed a new Zr additive and add Zr new technology. The Zr additive is simple, accurate and easy to use. The test and production confirmed that the use of such additives to the aluminum alloy with Zr, adding a simple method, adding Zr temperature can be reduced to 720 ~ 74 ℃, Zr recovery rate of more than 80%, but also to improve the internal ingot The purpose of metallurgical quality.
