汽車鑄件及其鑄造技術發展趨勢

  鑄造是最古老的金屬成形方法之一,汽車零件中大約有15%~20%為采用不同鑄造方法生產的鑄件,這些鑄件主要為動力系統關鍵部件和重要的結構部件。目前歐美汽車工業發達國家的汽車鑄件生產技術先進,產品質量好,生產效率高,環境污染小。鑄造原輔材料已形成系列化和標準化,整個生產過程已經實現了機械化、自動化和智能化。這些國家普遍采用數字化技術提升鑄造工藝設計水平,鑄件廢品率約為2%~5%,并且已經建立跨國服務系統并實現網絡技術支持。與之相比,我國的汽車鑄件雖然產量較大,但大多數都是附加值和技術含量較低,結構相對簡單的黑色鑄件,與國外水平差距較大。本文主要從汽車節能環保等方面的發展需求,論述了汽車鑄件和汽車技術的發展方向。

  等溫淬火球墨鑄鐵,不僅強度比普通鑄鋼材料有所提高,而且密度比鋼要低,其密度為7.1 g/cm3,而鑄鋼的密度為7.8 g/cm3,是近年來廣泛推薦采用的材料。采用等溫淬火球墨鑄鐵,在鑄件尺寸相同的條件下,比鑄鋼件輕10%。東風汽車公司在某型商用車進行了采用等溫淬火球墨鑄鐵替代鑄鋼件的輕量化驗證工作,并針對等溫淬火球墨鑄鐵件金巴黎彩票高強度特點,對14個懸架類零件進專家論壇行重新設計。一般來說,汽車鑄件的材料替換往往伴隨著零件的輕量化設計。
