一種復(fù)合結(jié)構(gòu)的氮化硅結(jié)合碳化硅陶瓷升液管的制作方法技術(shù)領(lǐng)域：本實(shí)用新型屬于特種陶瓷材料的制備技術(shù)領(lǐng)域，主要涉及一種復(fù)合結(jié)構(gòu)的氮化硅結(jié)合碳化硅陶瓷升液管。背景技術(shù)：升液管是低壓鑄造機(jī)上的關(guān)鍵部件之一，其性能及穩(wěn)定性直接影響鑄造產(chǎn)品的質(zhì)量和生產(chǎn)效率。其工作原理是下端插入保溫爐鋁合金熔液內(nèi)，上端連接鑄造模具腔，通過(guò)壓力作用鋁合金熔液由下而上進(jìn)入模具腔完成鑄造。根據(jù)工作條件要求升液管要具有良好的抗熱震性，抗鋁合金熔液的腐蝕，與鋁合金熔液不潤(rùn)濕，良好的氣密性和抗熱沖擊疲勞性。目前市場(chǎng)上主要產(chǎn)品有鑄鐵升液管、鈦酸鋁升液管和氮化硅結(jié)合碳化硅升液管；鑄鐵升液管在使用中易對(duì)鋁合金鑄件增鐵，且使用壽命短，影響生產(chǎn)效率；鈦酸鋁陶瓷的合成和燒結(jié)溫度不易控制，且強(qiáng)度不高；而氮化硅結(jié)合碳化硅升液管在鋁合金鑄造行業(yè)的使用比例越來(lái)越大，主要得益于其不與鋁合金熔液浸潤(rùn)，且耐腐蝕，抗熱震性好，但是純陶瓷型的氮化硅結(jié)合碳化硅升液管成本較高。為解決上述技術(shù)問(wèn)題，提出復(fù)合結(jié)構(gòu)的升液管，國(guó)內(nèi)復(fù)合結(jié)構(gòu)的升液管主要是采用鑄鐵管或無(wú)縫鋼管作為夾層材料，或是采用陶瓷內(nèi)襯來(lái)保證升液管的氣密性，采用鑄鐵管或無(wú)縫鋼管易對(duì)鑄造產(chǎn)品增鐵。</p><div

造成鑄件的夾雜缺點(diǎn)；對(duì)于金屬升液管而言，由于坩堝或熔融爐中的金屬液的溫度往往高達(dá)800至1000°C，因此金屬升液管(例如，鐵管)如果長(zhǎng)期浸泡在高溫金屬液(例如，鋁水)中，會(huì)導(dǎo)致升液管的金屬成分進(jìn)入高溫金屬液，如果這兩種金屬并不相同的話，就會(huì)嚴(yán)重影響產(chǎn)品的質(zhì)量，而升液管本身也會(huì)受到極大損害，另外，由于金屬受熱之后會(huì)產(chǎn)生膨脹，也會(huì)對(duì)金屬升液管產(chǎn)生影響。實(shí)用新型內(nèi)容本實(shí)用新型主要解決的技術(shù)問(wèn)題是提供一種既具有較高的牢固度，又不會(huì)與高溫金屬液發(fā)生不利反應(yīng)，能夠減少澆注時(shí)液體金屬的噴濺和對(duì)留在坩堝底部的金屬?zèng)_擊攪動(dòng)的低壓鑄造升液管。為解決上述技術(shù)問(wèn)題，本實(shí)用新型采用的一個(gè)技術(shù)方案是提供一種低壓鑄造升液管，包括同心設(shè)置的外管和內(nèi)管，所述內(nèi)管的內(nèi)壁上設(shè)置有碳化硅薄膜，升液管進(jìn)口處設(shè)有一個(gè)與升液管固定連接的阻尼器，所述阻尼器側(cè)面均勻設(shè)置有若干小孔。在本實(shí)用新型一個(gè)較佳實(shí)施例中，所述外管為耐火水泥管，所述內(nèi)管為金屬管。在本實(shí)用新型一個(gè)較佳實(shí)施例中，所述金屬管為不銹鋼管、鐵管或鋼管中的一種。在本實(shí)用新型一個(gè)較佳實(shí)施例中，所述小孔為4-8個(gè)。在本實(shí)用新型一個(gè)較佳實(shí)施例中。</p><div
