升液管本實(shí)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(jī)廠都對(duì)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(jì)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(gè)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(yàn)，一個(gè)質(zhì)量的升液管應(yīng)該具備以下特點(diǎn):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(qiáng)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(jià)格經(jīng)濟(jì)，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(huì)造成生產(chǎn)中工藝控制困難，鑄件夾渣缺點(diǎn)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。
