鈦酸鋁是氧化鋁和鈦白粉按一定化學(xué)比例的混合物，結(jié)構(gòu)屬斜方晶系，鈦酸鋁陶瓷材料具有較高的熔點(diǎn)（1860℃±10℃），較低的熱膨脹系數(shù)（在RT—1000℃條件下，α＜×10-6／℃),并具有優(yōu)良的抗熱震性。另外，它具有與許多金屬（特別是有色金屬）熔體及玻璃熔液不潤(rùn)濕的特性。因此，鈦酸鋁陶瓷可廣泛應(yīng)用于耐高溫、抗熱震、耐腐蝕等條件苛刻的環(huán)境中。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。鈦酸鋁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。公司采用德國(guó)技術(shù)生產(chǎn)的鈦酸鋁升液管使用壽命長(zhǎng)、綜合性能達(dá)到國(guó)際先進(jìn)水平。具有以下特點(diǎn)：1、較低的熱膨脹系數(shù).2、優(yōu)異的抗熱沖擊性能.3、與鋁熔液等有色金屬熔液不浸潤(rùn).4、耐腐蝕性?xún)?yōu)良.5、耐高溫（可在1400℃）下使用6、可以很好的適應(yīng)高溫下的氧化問(wèn)題，能夠使低壓鑄造機(jī)在生產(chǎn)過(guò)程中實(shí)現(xiàn)其自動(dòng)化與連續(xù)性，從而提高了其生產(chǎn)效率。

氮化硅升液管應(yīng)用于低壓鑄造保溫爐。中國(guó)作為當(dāng)代的制造大國(guó)，也是世界的制造中心，升液管作為低壓鑄造保溫爐的必需品，已經(jīng)經(jīng)過(guò)了幾代的材料“進(jìn)化”，從**初的金屬材料到陶瓷材料，從普通陶瓷材料到復(fù)合陶瓷材料。直到氮化硅升液管的出現(xiàn)，才基本解決了升液管使用中的幾大問(wèn)題：1、耐腐蝕性，金屬材質(zhì)的升液管在高溫的金屬溶液里很容易被腐蝕掉，即便使用復(fù)合陶瓷的升液管，比如現(xiàn)在還大量使用的碳化硅材質(zhì)，腐蝕也非常嚴(yán)重，導(dǎo)致其使用壽命在1--2個(gè)月以?xún)?nèi)。2、積瘤和掛渣，傳統(tǒng)升液管被腐蝕后，加上本身氣孔率較高，容易產(chǎn)生掛渣和積瘤現(xiàn)象，導(dǎo)致管道變窄甚至堵塞。3、保證產(chǎn)品的純度；升液管被腐蝕后，雜質(zhì)會(huì)被帶到產(chǎn)品中，所以目前金屬材質(zhì)的升液管只會(huì)在低端產(chǎn)品的生產(chǎn)上還會(huì)被使用；而碳化硅升液管的雜質(zhì)含量也嚴(yán)重影響到了產(chǎn)品品質(zhì)以及產(chǎn)業(yè)升級(jí)。氮化硅材質(zhì)的升液管，耐高溫、熱膨脹系數(shù)低（變形量少）、密封性好、通孔光滑、氣孔率低、不掛渣積瘤、不腐蝕、不會(huì)帶進(jìn)雜質(zhì)，很大提升了金屬產(chǎn)品的品質(zhì)。
