3D技術在大型鑄鍛件行業的應用優勢

1. 我國大型鑄鍛件的生產現狀和應用

大型鑄鍛件制造業是一個非常特殊的行業,既是我國經濟建設、發展的關鍵行業,也是我國重大裝備制造業的基礎,更是我國國防建設必須的行業;是關系到國家安全和經濟命脈的不可或缺的戰略性行業,也是國家能力的重要組成;大型鑄鍛件行業的發展水平是衡量一個國家綜合國力的重要標志。大型鑄鍛件產品是電力、冶金、石化、造船、鐵路、礦山、航空航天、軍工、工程等裝配的基礎部件,其經濟帶動性強,輻射作用大,是產業鏈上不可缺少的重要一環節。大型鑄鍛件是重大裝備的典型關鍵部件,既可以是各大型設備的備件,也可以是受力部件,如軋機中的機架、支承輥、工作輥,發電汽輪機中的轉子、大軸和轉輪體等。作為基礎行業,大型鑄鍛件的需求量是極大的。就拿我國能夠提供大型優質鑄鍛件的主要企業如一重、二重和上重來說,2007年一重鍛件產量11萬t、二重7萬t、上重5萬 t,由此可知鑄鍛件的市場和需求非常大。但我國重型裝備制造的龍頭企業大鍛件制造的材料利用率還遠落后于世界先進水平,我國鑄鍛鍛件材料利用率為 50%~55%,而韓國為60%~65%,日本則為70%~75%。鑄鍛件材料的利用率是大型鑄鍛件生產的一個瓶頸,與此同時,一個大型鑄鍛件的成形過程也是極其復雜和繁瑣的。以下是某軋機機架簡略的鑄造加工過程和相關數據(見附表)。其鑄造過程主要有:鑄造工藝設計、模樣制作、造型、制芯、澆注、落砂、割冒口、熱處理、表面處理、粗加工、二次精整及精加工等。在此過程中由表中的數據中可知整個過程中的勞動力、材料、能源等的大量消耗和過程之復雜,并且整個鑄件的生產周期長,最少也需要兩個月左右。
