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，山東高溫升液管批發(fā)零售，**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，山東高溫升液管批發(fā)零售，在車輪生產(chǎn)中的作用舉足輕重。依據(jù)生產(chǎn)經(jīng)驗，一個質量的升液管應該具備以下特點: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，山東高溫升液管批發(fā)零售，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)有技術中的升液管很難兼具上述幾種特質，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。

鈦酸鋁是氧化鋁和鈦白粉按一定化學比例的混合物，結構屬斜方晶系，鈦酸鋁陶瓷材料具有較高的熔點（1860℃±10℃），較低的熱膨脹系數(shù)（在RT—1000℃條件下，α＜×10-6／℃),并具有優(yōu)良的抗熱震性。另外，它具有與許多金屬（特別是有色金屬）熔體及玻璃熔液不潤濕的特性。因此，鈦酸鋁陶瓷可廣泛應用于耐高溫、抗熱震、耐腐蝕等條件苛刻的環(huán)境中。低壓鑄造升液管是低壓鑄造機上的關鍵部件之一。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。鈦酸鋁因其較低的熱膨脹悉數(shù)、良好的抗熱震、不粘鋁等特點成為制備升液管的理想材料。公司采用德國技術生產(chǎn)的鈦酸鋁升液管使用壽命長、綜合性能達到國際先進水平。具有以下特點：1、較低的熱膨脹系數(shù).2、優(yōu)異的抗熱沖擊性能.3、與鋁熔液等有色金屬熔液不浸潤.4、耐腐蝕性優(yōu)良.5、耐高溫（可在1400℃）下使用6、可以很好的適應高溫下的氧化問題，能夠使低壓鑄造機在生產(chǎn)過程中實現(xiàn)其自動化與連續(xù)性，從而提高了其生產(chǎn)效率。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東高溫升液管批發(fā)零售"

低壓鑄造是將鑄型放在一個密閉的爐子上面，型腔的下面用一個管(叫升液管)和爐膛里的金屬液相通。如果在爐膛中金屬液面上加入帶壓力的空氣，金屬液會從升液管中流入型腔。待金屬液凝固以后，將爐膛中的壓縮空氣釋放，未凝固的金屬從升液管中流回到爐中?？刂屏魅霠t膛空氣的壓力、速度,就可以控制金屬流入型腔中的速度和壓力，并能讓金屬在壓力下結晶凝固。這種工藝特點是鑄件在壓力下結晶，結構致密，機械性能好，金屬利用率高。低壓鑄造工藝目前在中國大陸已經(jīng)相當成熟，適合少人化生產(chǎn)管理，已經(jīng)被所有整車廠認可是當前中國大陸鋁合金輪轂制造業(yè)的主流工藝，產(chǎn)品主要銷往OEM和海外零售市場。采用低壓鑄造工藝制造的鋁合金輪轂，由于輪輻是末端冷卻凝固的，所以部分特殊造型輪轂的輪輻易出現(xiàn)縮松等質量問題，而輪輞部分由于**早結晶則強度較好。
