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。
