Abstract:有系統改變A201鋁合金平板鑄件的長度、厚度、及冒口大小的方案設計,並分別添加0.50%、0.75%及1.00%的銀含量,探討銀含量的改變對不同鑄造方案的A201平板鑄件補充距離的影響程度,進而於A201鋁合金鑄造實務工作時,可為冒口設計及金屬凝固之參考,為本研究的目的。砂模的鑄沙是100%矽砂。由實驗結果顯示,在以抗拉強度為補充距離參考的條件下,A201鋁合金平板鑄件的補充距離不僅受鑄造方案的影響,亦受到銀含量之影響,以銀含量0.75%的鋁合金平板鑄件補充性質最佳。

 

With system based on mechanical Ag content, the riser size and the casting geometry to find out the influence of Ag content on the feeding distance based on mechanical properties criterion the A201 aluminum alloy plate castings is discussed in this study. The sand molds with end chill were made of 100% silica sand. The result shows that Ag content affects the feeding distance and mechanical properties of the castings. The feeding distance in A201 Aluminum alloy plate castings depends not only on the riser and gating system but also on the Ag content. The longer feeding distance of the plate castings appear in 0.75%AgA201 aluminum alloy.
