鑄造廠家看鋁鑄件
鋁(lv)(lv)鑄(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)可以被(bei)制(zhi)造為鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)汽(qi)車(che)配(pei)(pei)件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)汽(qi)車(che)發動機(ji)(ji)管件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)發動機(ji)(ji)氣(qi)(qi)缸(gang)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)汽(qi)油機(ji)(ji)氣(qi)(qi)缸(gang)缸(gang)蓋、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)氣(qi)(qi)門(men)搖臂、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)氣(qi)(qi)門(men)支座、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)電力配(pei)(pei)件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)電機(ji)(ji)端(duan)蓋、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)殼(ke)體、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)泵殼(ke)體、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)建筑配(pei)(pei)件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)裝(zhuang)飾(shi)配(pei)(pei)件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)護(hu)欄配(pei)(pei)件(jian)(jian)、鋁(lv)(lv)壓(ya)(ya)(ya)(ya)(ya)鑄(zhu)(zhu)(zhu)(zhu)(zhu)鋁(lv)(lv)輪等等零(ling)件(jian)(jian)。縮松缺陷(xian)特征(zheng):鋁(lv)(lv)鑄(zhu)(zhu)(zhu)(zhu)(zhu)件(jian)(jian)縮松一(yi)般產生在內(nei)澆道附近飛冒口根部厚大(da)部位、壁(bi)的厚薄轉(zhuan)接處(chu)和(he)具有大(da)平面的薄壁(bi)處(chu)。
在鑄造件鑄態時斷口(kou)為灰色(se)(se),淺(qian)黃(huang)色(se)(se)經熱(re)處理后為灰白淺(qian)黃(huang)或灰黑色(se)(se)在x光底(di)片上呈云霧狀(zhuang)嚴重(zhong)的(de)呈絲狀(zhuang)縮松可(ke)通過X光、熒光低倍斷口(kou)等(deng)檢查(cha)方法發現產生(sheng)原(yuan)因:
1.冒口補縮作用差
2.爐料含氣量太多
3.內澆道附近過熱
4.砂型水(shui)分過多,砂芯(xin)未烘(hong)干
5.合金晶粒粗大
6.鑄(zhu)件在鑄(zhu)型中的(de)位(wei)置不當
7.澆(jiao)注(zhu)(zhu)溫度過高,澆(jiao)注(zhu)(zhu)速度太快
鋁鑄件防止方法:
1.從冒(mao)口補澆金屬液(ye),改進(jin)冒(mao)口設計
2.爐料(liao)應清潔無腐蝕
3.鑄件縮(suo)松處設置(zhi)冒口,安放冷鐵(tie)或冷鐵(tie)與冒口聯(lian)用
4.控制型(xing)砂水分,和(he)砂芯(xin)干燥
5.采取細化(hua)品(pin)粒的措施(shi)
6.改進鑄件在鑄型中的位置降低澆注(zhu)溫(wen)度和澆注(zhu)速度
