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(zhǎng)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)，山東碳化硅陶瓷升液管生產(chǎn)廠家，也因此會(huì)造成生產(chǎn)中工藝控制困難，山東碳化硅陶瓷升液管生產(chǎn)廠家，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，山東碳化硅陶瓷升液管生產(chǎn)廠家，并提高了企業(yè)的制造成本。奧翔硅碳受行業(yè)客戶的好評(píng)，值得信賴。山東碳化硅陶瓷升液管生產(chǎn)廠家</p><div

低壓鑄造升液管是低壓鑄造機(jī)上的關(guān)鍵部件之一。壓鑄過程中，鋁熔液（溫度700~900℃）每隔3～5分鐘從升液管內(nèi)被壓送到模具型腔。傳統(tǒng)生產(chǎn)工藝中采用鋼制升液管，由于抗熱震性不佳、耐腐蝕性差，使用壽命短、更換頻率頻繁，不能滿足連續(xù)、***生產(chǎn)的要求。氮化硅升液管因其較低的熱膨脹悉數(shù)、良好的抗熱震、不粘鋁等特點(diǎn)成為制備升液管的理想材料。工藝：1、冷等靜壓成型2、機(jī)械加工3、反應(yīng)燒結(jié)/氣壓燒結(jié)特點(diǎn)：1、耐高溫、耐腐蝕、與鋁熔液等有色金屬熔液不浸潤(rùn)2、優(yōu)異的導(dǎo)熱性，抗熱沖擊性強(qiáng)，不炸裂3、抗氧化，使用壽命長(zhǎng)4、可根據(jù)客戶要求規(guī)格制作性能參數(shù)密度(g/cm3)〉顯氣孔率(%)〈洛氏硬度(HRA)〉93空氣中比較高使用溫度(℃)1400保護(hù)氣氛中比較高使用溫度(℃)1800破裂表面能(20℃)/(J/m2)133抗彎強(qiáng)度(MPa)986(20℃)，485(1400℃)比熱（J/g·K）泊松比(20℃)熱導(dǎo)率［W/(m·K)］熱擴(kuò)散系數(shù)(300℃)/(cm2/s)電阻率(Ω·m)(20℃)，4x108。

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，不能夠滿足齒輪箱對(duì)于Fe含量的高要求。技術(shù)實(shí)現(xiàn)要素：本發(fā)明的目的在于提供一種在使用過程中能避免被腐蝕而產(chǎn)生增鐵的升液管。本發(fā)明的第二目的在于提供一種制作簡(jiǎn)單的升液管的制造方法。實(shí)現(xiàn)上述目的技術(shù)方案是：一種升液管，包括鐵質(zhì)升液管，還包括陶瓷保護(hù)套管和耐火棉過渡層，所述耐火棉過渡層包裹在鐵質(zhì)升液管上，所述陶瓷保護(hù)套管包覆在耐火棉過渡層上。所述鐵質(zhì)升液管的內(nèi)、外管壁上均具有固定凸臺(tái)，所述耐火棉過渡層固定在固定凸臺(tái)上。所述固定凸臺(tái)在鐵質(zhì)升液管的一個(gè)軸向高度上的內(nèi)、外管壁上各有3個(gè)，且沿鐵質(zhì)升液管周向均勻分布。所述固定凸臺(tái)在鐵質(zhì)升液管的三個(gè)軸向高度上的內(nèi)、外管壁上各有3個(gè)，且沿鐵質(zhì)升液管周向均勻分布。所述固定凸臺(tái)為半球型，球徑為Φ10mm±1mm。所述固定凸臺(tái)焊接在鐵質(zhì)升液管上。實(shí)現(xiàn)上述第二目的技術(shù)方案是：一種上述升液管的制造方法，鐵質(zhì)升液管采用普通45號(hào)鋼材料制造，耐火棉過渡層采用普通纖維耐火棉材料制作，在鐵質(zhì)升液管的內(nèi)、外管壁軸向高度上選定位置制出固定凸臺(tái)。奧翔硅碳為客戶服務(wù)，要做到更好。</p><div
