升液管本實用新型涉及一種升液管，具體的說涉及一種鋁合金車輪低壓鑄造使用的升液管。由于鋁合金車輪是汽車上**為重要的外觀件及**件之一，因此各主機廠都對車輪供貨提出了嚴格的要求，無論是尺寸、外觀還是性能均要滿足一定的設(shè)計標準。目前，世界上約80%的鋁合金車輪生產(chǎn)采用低壓鑄造成形工藝，該技術(shù)屬于底部中心澆注形式，保溫爐內(nèi)的高溫鋁液通過升液管道進入模具型腔，并在模具及外部冷卻的共同作用下凝固成形，**終得到合格的毛坯鑄件。在整個鑄造系統(tǒng)中，升液管作為連接保溫爐與模具的通道，在車輪生產(chǎn)中的作用舉足輕重。依據(jù)生產(chǎn)經(jīng)驗，一個質(zhì)量的升液管應(yīng)該具備以下特點:良好的保溫性，比較大限度的減少鋁液在進入型腔前的熱量損失，以防止發(fā)生鋁液凍死事情；具備較強的鋁液過濾能力，不可以將保溫爐內(nèi)的氧化膜等雜質(zhì)帶入模具型腔，形成鑄件夾渣廢品；具有良好的耐腐蝕性、耐高溫性，保證升液管有較長的使用壽命；價格經(jīng)濟，節(jié)約生產(chǎn)成本。然而，現(xiàn)有技術(shù)中的升液管很難兼具上述幾種特質(zhì)，也因此會造成生產(chǎn)中工藝控制困難，鑄件夾渣缺點頻發(fā)，產(chǎn)品外觀不達標導致客戶抱怨等等問題，這些問題都嚴重的制約著車輪的成品率，并提高了企業(yè)的制造成本。 </p><p> 根據(jù)權(quán)利要求的低壓鑄造升液管，其特征在于所述阻尼器通過銷釘與升液管固定連接。**摘要本實用新型公開了一種低壓鑄造升液管，包括同心設(shè)置的外管和內(nèi)管，所述內(nèi)管的內(nèi)壁上設(shè)置有碳化硅薄膜，升液管進口處設(shè)有一個與升液管固定連接的阻尼器，所述阻尼器側(cè)面均勻設(shè)置有若干小孔。本實用新型低壓鑄造升液管減少了澆注時的金屬噴濺和對坩堝底部剩余金屬的沖擊攪動，減少了逐漸的夾雜缺點，明顯提高了鑄件質(zhì)量，同時，由于采用金屬管和非金屬管同心設(shè)置的結(jié)構(gòu)，本實用新型的升液管既可以具有期望的強度，又可以具有良好的承重能力和耐磨性能，另外，由于碳化硅薄膜和耐火水泥管可以良好地防止金屬液滲透入金屬管，因此可以有效地防止金屬管與金屬液之間發(fā)生不希望的化學反應(yīng)。奧翔硅碳從國內(nèi)外引進了一大批先進的設(shè)備，實現(xiàn)了工程設(shè)備的現(xiàn)代化。</p><div

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元素Fe超標，另外，在使用過程中，若鐵質(zhì)升液管發(fā)生局部被腐蝕導致漏氣，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，極易發(fā)生Fe元素超標。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)的涂料保護方法無法阻礙鋁液增Fe。奧翔硅碳公司可靠的質(zhì)量保證體系和經(jīng)營管理體系，使產(chǎn)品質(zhì)量日趨穩(wěn)定。天津硅碳升液管廠家</p><p
