特種鋼精密鑄造全封閉葉輪
詳細介紹
特種鋼精密鑄造是一種少切削或無切削的鑄造工藝,是鑄造行業中的一項優異的工藝技術,一般都應用非常廣泛。那么我們大家在操作使用這種不銹鋼精密鑄造的時候,我們為了提高特種鋼精密鑄造全封閉葉輪質量的時候,都有哪些方法?
 
1:進程規劃:嚴格控制進程,合箱前,確保外型和砂芯是帶溫狀況,澆注時確保鋼液的流動性,對外表粗糙破損的地方選用福士科ISOMOL300醇基鋯英粉涂料進行刷涂后點火烘烤,使鑄型外表潤滑。
 
2:模具規劃:不銹鋼鑄件的外表處理榜首從模具下手,將模具的外表處理潔凈,即外表用砂紙擦凈后刷硝基油漆,對精度高的鑄件選用金屬或塑料模具,進步模具外表的光潔度。
 
3:打磨規劃:打磨環節去掉飛邊毛刺,對外表不平坦處,進行打磨處理,潤滑過度。關于熱處理完的鑄件選用打磨精拋處理。
