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(guò)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(mǎn)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(hù)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。

升液管的制作方法：本實(shí)用新型公開(kāi)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(guò)連接螺栓緊固；升液管本體a（2）設(shè)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(shè)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(shè)置過(guò)濾片（4），升液管本體b（8）的下端設(shè)置第二過(guò)濾片（7）；升液管本體b的內(nèi)壁截面呈“正錐型”，錐角5?8°，開(kāi)口逐漸縮小，升液管本體a的內(nèi)壁截面呈“直線(xiàn)+倒錐型”，錐角5?10°。本實(shí)用新型涉及一種升液管，具體的說(shuō)涉及一種鋁合金車(chē)輪低壓鑄造使用的升液管。[0002]由于鋁合金車(chē)輪是汽車(chē)上**為重要的外觀(guān)件及**件之一，因此各主機(jī)廠(chǎng)都對(duì)車(chē)輪供貨提出了嚴(yán)格的要求，無(wú)論是尺寸、外觀(guān)還是性能均要滿(mǎn)足一定的設(shè)計(jì)標(biāo)準(zhǔn)。目前，世界上約80%的鋁合金車(chē)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(guò)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。</p></p><br
