氮化硅升液管應用于低壓鑄造保溫爐。中國作為當代的制造大國，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)過了幾代的材料“進化”，從**初的金屬材料到陶瓷材料，從普通陶瓷材料到復合陶瓷材料。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)，腐蝕也非常嚴重，導致其使用壽命在1--2個月以內(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)會被帶到產(chǎn)品中，所以目前金屬材質(zhì)的升液管只會在低端產(chǎn)品的生產(chǎn)上還會被使用；而碳化硅升液管的雜質(zhì)含量也嚴重影響到了產(chǎn)品品質(zhì)以及產(chǎn)業(yè)升級。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、不會帶進雜質(zhì)，很大提升了金屬產(chǎn)品的品質(zhì)。

本實用新型屬于低壓鑄造技術(shù)領(lǐng)域，具體涉及一種低壓鑄造的升液管。背景技術(shù)：在低壓鑄造技術(shù)中，升液管是連接保溫爐和模具型腔的通道，升液管的結(jié)構(gòu)特征、保溫效果和抗腐蝕性能等直接影響著鑄件的質(zhì)量。在通常的鑄造過程中升液管一般采用圓柱直管，率先進入模具的鋁液與升液管熱量交換大，熱量損失較大，容易發(fā)生升液管凍死現(xiàn)象或進入型腔提前凝固現(xiàn)象；在結(jié)晶保壓結(jié)束后，鋁液回流在直管中受到的阻力小，對保溫爐鍋底沖刷嚴重，同時容易攪動鍋底的雜質(zhì)，下次鑄造過程中容易將雜質(zhì)引入模具無法保證鑄件質(zhì)量。技術(shù)實現(xiàn)要素：為了解決上述存在的問題，本實用新型提供了一種低壓鑄造的升液管。本實用新型的技術(shù)方案是這樣實現(xiàn)的：升液管為一體結(jié)構(gòu)的鋼管，包括第三過濾片、第二過濾片、首過濾片、倒錐型引流槽、法蘭盤、沉頭孔、上波紋管、下波紋管、圓柱直管、濾片。為充分發(fā)揮升液管的功能可在升液管內(nèi)部添加鈦酸鋁陶瓷等材料提高升液管的抗腐蝕能力，在升液管外部添加碳化硅等材料提高升液管的保溫能力。作為本實用新型的進一步優(yōu)化方案，所述沉頭孔均勻分布在所述法蘭盤表面，通過沉頭螺釘將升液管與保溫爐蓋緊密連接在一起。 </p><p style="text-indent:25px">低壓鑄造是將鑄型放在一個密閉的爐子上面，型腔的下面用一個管(叫升液管)和爐膛里的金屬液相通。如果在爐膛中金屬液面上加入帶壓力的空氣，金屬液會從升液管中流入型腔。待金屬液凝固以后，將爐膛中的壓縮空氣釋放，未凝固的金屬從升液管中流回到爐中?？刂屏魅霠t膛空氣的壓力、速度,就可以控制金屬流入型腔中的速度和壓力，并能讓金屬在壓力下結(jié)晶凝固。這種工藝特點是鑄件在壓力下結(jié)晶，結(jié)構(gòu)致密，機械性能好，金屬利用率高。擠壓鑄造也稱為液態(tài)模鍛，是一種集鑄造和鍛造特點于一體的新工藝，該工藝是將一定量的金屬液體直接澆入敞開的金屬型內(nèi)，通過沖頭以一定的壓力作用于液體金屬上，使之充填、成形和結(jié)晶凝固，并在結(jié)晶過程中產(chǎn)生一定量的塑性變形。擠壓鑄造充型平穩(wěn)，沒有湍流和不包卷氣體，金屬直接在壓力下結(jié)晶凝固，所以鑄件不會產(chǎn)生氣孔、縮孔和縮松等鑄造缺點，且結(jié)構(gòu)致密、晶粒細化，機械性能比低壓鑄造件高。產(chǎn)品既有接近鍛件的優(yōu)良機械性能，又有精鑄件一次精密成形的高效率、高精度，且投資極大低于低壓鑄造法。缺點是液態(tài)模鍛的產(chǎn)品與傳統(tǒng)鍛造產(chǎn)品一樣，需要銑削加工來完成輪輻的造型。誠摯的歡迎業(yè)界新朋老友走進奧翔硅碳！</p><div
