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(yán)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(biāo)準(zhǔn)。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(jìn)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(jìn)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(dá)標(biāo)導(dǎo)致客戶抱怨等等問題，這些問題都嚴(yán)重的制約著車輪的成品率，并提高了企業(yè)的制造成本。奧翔硅碳為客戶服務(wù)，要做到更好。山東升液管廠家</p><p

造成鑄件的夾雜缺點；對于金屬升液管而言，由于坩堝或熔融爐中的金屬液的溫度往往高達(dá)800至1000°C，因此金屬升液管(例如，鐵管)如果長期浸泡在高溫金屬液(例如，鋁水)中，會導(dǎo)致升液管的金屬成分進(jìn)入高溫金屬液，如果這兩種金屬并不相同的話，就會嚴(yán)重影響產(chǎn)品的質(zhì)量，而升液管本身也會受到極大損害，另外，由于金屬受熱之后會產(chǎn)生膨脹，也會對金屬升液管產(chǎn)生影響。實用新型內(nèi)容本實用新型主要解決的技術(shù)問題是提供一種既具有較高的牢固度，又不會與高溫金屬液發(fā)生不利反應(yīng)，能夠減少澆注時液體金屬的噴濺和對留在坩堝底部的金屬沖擊攪動的低壓鑄造升液管。為解決上述技術(shù)問題，本實用新型采用的一個技術(shù)方案是提供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(jìn)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。在本實用新型一個較佳實施例中，所述外管為耐火水泥管，所述內(nèi)管為金屬管。在本實用新型一個較佳實施例中，所述金屬管為不銹鋼管、鐵管或鋼管中的一種。在本實用新型一個較佳實施例中，所述小孔為4-8個。在本實用新型一個較佳實施例中。山東升液管廠家</p><p
