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)月以內(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)。
