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；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，并明顯提高了企業(yè)的制造成本。本實(shí)用新型的目的是提供一種有良好保溫性、很強(qiáng)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(jì)性的車輪低壓鑄造用升液管。[0004]本實(shí)用新型的技術(shù)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(shè)置法蘭，借助螺栓將本實(shí)用新型連接在機(jī)臺(tái)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(duì)惡劣。</p><div
