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，與鋁合金熔液不潤濕，良好的氣密性和抗熱沖擊疲勞性。目前市場上主要產(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)的使用比例越來越大，主要得益于其不與鋁合金熔液浸潤，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)問題，提出復(fù)合結(jié)構(gòu)的升液管，國內(nèi)復(fù)合結(jié)構(gòu)的升液管主要是采用鑄鐵管或無縫鋼管作為夾層材料，或是采用陶瓷內(nèi)襯來保證升液管的氣密性，采用鑄鐵管或無縫鋼管易對鑄造產(chǎn)品增鐵。</p><p>

style="text-indent:25px">氮化硅升液管裝配時應(yīng)注意的問題，下面奧翔硅碳制品給我大家講解一下：升液管與爐口及模具在對接安裝時，密封要嚴(yán)密，氣密封間隙的松緊與密封材料的選取十分重要。過緊時壓力大，長時間受力容易壓裂，過松時在很短時間里又會漏氣。另外密封壓緊部位的選取要合理，避免使升液管法蘭盤受力錯位而減短使用壽命。要精確把握間隙、材料，安裝手法等環(huán)節(jié)逐步積累經(jīng)驗(yàn)。升液管的低壓鑄造原理是在一密封的容器中，通入干燥的壓縮空氣或惰性氣體，使升液管的金屬液在氣體壓力下，自下而上地通過陶瓷升液管和澆注系統(tǒng)，平穩(wěn)地進(jìn)入鑄型中去，保持容器內(nèi)氣體壓力至鑄件完全凝固為止，然后解除液面上的壓力，使陶瓷升液管和澆道中沒有凝固的金屬液由于重力而回到容器中，這樣在上面的鑄型中就形成所需要的鑄件。由此可見，其凝固順序是由上而下的，所以在鑄型設(shè)計(jì)時，都需人為地造成遠(yuǎn)離澆口的部分首先凝固，因?yàn)榈蛪鸿T造對“順序凝固”的要求是非常突出的。奧翔硅碳以質(zhì)量求生存，以信譽(yù)求發(fā)展！云南升液管公司</p><p
