隨著國內(nèi)高鐵市場的快速發(fā)展，高鐵齒輪箱作為動車組傳動系統(tǒng)的部件之一，齒輪箱鑄件的化學(xué)元素要求之高近乎苛刻，低壓鑄造齒輪箱鑄件通常采用鐵質(zhì)升液管，特定的鑄造工藝決定了升液管必須在鋁液中長時間浸泡，在生產(chǎn)制造過程中，F(xiàn)e（鐵）元素與Al（鋁）元素極易發(fā)生反應(yīng)，鐵質(zhì)升液管很容易被腐蝕，污染鋁液，時而伴隨著齒輪箱鑄件的化學(xué)元素Fe超標(biāo)，另外，在使用過程中，若鐵質(zhì)升液管發(fā)生局部被腐蝕導(dǎo)致漏氣，現(xiàn)場很難發(fā)現(xiàn)，澆注時極易造成批量質(zhì)量問題。Fe元素在鋁合金中是一種雜質(zhì)元素，這種雜質(zhì)相主要以一種板條狀或針狀形成的AlFeSi相存在于合金基體中，嚴(yán)重割裂基體，對齒輪箱鑄件的疲勞性能、沖擊韌性、延伸率等性能指標(biāo)產(chǎn)生極大的影響，齒輪箱鑄件Fe含量要求≤，然而，在實際生產(chǎn)過程中增Fe不可避免，受制于原材料成本的原因，原材料Fe含量一般在，本身增Fe空間就極其狹窄，一旦控制不當(dāng)，極易發(fā)生Fe元素超標(biāo)。傳統(tǒng)的齒輪箱鑄造過程中會在升液管壁涂覆一種涂料，但*通過涂料方式阻止增Fe效果不夠理想，因為在低壓鑄造生產(chǎn)過程中，每生產(chǎn)一件毛坯均需周期性增壓與泄壓一次，周期性的沖刷，涂料很難維持，因此**采用傳統(tǒng)的涂料保護(hù)方法無法阻礙鋁液增Fe。
