摘要
文章通过数值模拟的方法,研究了不同厚度的冷铁在常用的铝硅合金AlSi7Mg的凝固过程中的影响.通过实验所得到的一系列结论可以看出,对于直径较大的试样,增加冷铁厚度,可以极大地改善其凝固条件,其中对于模数小于20mm的铸件,冷铁厚度在30mm左右即可.
The effect of cold iron has been proved and analyzed in this paper by applying a series of numerical simulation experiment.It can be concluded from the results that for those large diameter work pieces,by increasing the thickness of cold iron,the solidification process could be optimized.If the modulus of work pieces is less than 20 mm,the appropriate thickness of cold iron should be 30 mm.
