id="vprjqse" class="box"><p><p> 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，湖北氮化硅升液管批發(fā)。采用低壓鑄造工藝制造的鋁合金輪轂，湖北氮化硅升液管批發(fā)，湖北氮化硅升液管批發(fā)，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(zhì)量問題，而輪輞部分由于**早結晶則強度較好。

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；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，并明顯提高了企業(yè)的制造成本。本實用新型的目的是提供一種有良好保溫性、很強鋁液撇渣過濾能力、較高耐蝕性、較長的使用壽命以及優(yōu)良的經(jīng)濟性的車輪低壓鑄造用升液管。[0004]本實用新型的技術方案是:升液管，包括升液管本體、連接螺栓、定位圓銷、密封墊、過濾片。升液管本體包括升液管本體a、升液管本體b，二者通過連接螺栓緊固。升液管本體a設置法蘭，借助螺栓將本實用新型連接在機臺底板上。升液管本體a在上端，不浸入鋁液，選用普通的鐵質(zhì)材料制作。下端的升液管本體b始終與高溫鋁液接觸，工作狀況相對惡劣。</p><div

升液管的制作方法本實用新型公開了一種升液管，包括升液管本體a（2）、升液管本體b（8），二者通過連接螺栓緊固；升液管本體a（2）設置法蘭，升液管本體a（2）選用普通鐵質(zhì)材料制作，升液管本體b（8）選用氮化硼、碳化硅、陶瓷等耐高溫、耐腐蝕材料制作；升液管本體a（2）和升液管本體b（8）的接縫處設置密封墊圈（9），升液管本體a（2）和升液管本體b（8）的接縫處設置過濾片（4），升液管本體b（8）的下端設置第二過濾片；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，**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。</p></p><br
