在低壓鑄造技術中，廣西升液管，廣西升液管，廣西升液管，升液管是連接保溫爐和模具型腔的**通道，升液管的結構特征、保溫效果和抗腐蝕性能等直接影響著鑄件的質量。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；在結晶保壓結束后，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，下次鑄造過程中容易將雜質引入模具無法保證鑄件質量。 </p> <p> <br /> </p> <p> <br /> 我公司生產(chǎn)的產(chǎn)品、設備用途非常多。廣西升液管</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣西升液管,升液管"

升液管的技術領域，具體地說是一種氮化硅制作的低壓鑄造和真空吸鑄耐熱合金升液管的配方及其制備方法。背景技術：低壓鑄造和真快吸鑄是介于重力鑄造和壓力鑄造之間的一種鑄造方法，升液管是該技術的關鍵。目前低壓鑄造和真快吸鑄耐熱鋼所使用的升液管的壽命較低，抗熱疲勞和抗高溫氧化腐蝕較差，有的效果較好，但經(jīng)濟價格太昂貴，無法在生產(chǎn)上應用。技術實現(xiàn)要素：本發(fā)明的目的在于提供一種改進的氮化硅升液管的配方及其制備方法，它可克服現(xiàn)有技術中升液管壽命較低，抗熱疲勞和抗高溫氧化腐蝕較差的一些不足。為了實現(xiàn)上述目的，本發(fā)明的技術方案是：一種氮化硅升液管的配方，其特征在于：所述的升液管由氮化硅粉和助燒劑混合而成的粉體制成，其中助燒劑占氮化硅粉的質量百分比為1％～9％。氮化硅粉由重量百分比為90％～95％的亞微米氮化硅粉和5％～10％的納米氮化硅粉混合組成。推薦的，所述的助燒劑為納米Al2O3和Y2O3。一種氮化硅升液管的制備方法，其特征在于：所述的制備方法包括如下步驟：a、將氮化硅粉和助燒劑混合后得到混合粉體，然后將混合粉體與無水乙醇混合，制成漿料；b、將得到的漿料進行噴霧干燥造粒，經(jīng)出料得到粉粒體；c、將粉粒體填充于升液管模具后成型。</p><p>
