mm左右，孔徑8～10 mm），在鋼管外面包兩層120～150目的金屬網(wǎng)，以防止細紗及粉塵被吸入抽氣室。適用于面積大于1200×1200mm中大型砂箱。<br>揚州負壓V法鑄造工藝除塵濾氣罐采用介質分離，抽吸進來的氣體與水混合。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">鑄型強度不夠或者不均勻，在有些具有大平面特點的鑄件生產上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時候常常為了落砂的簡易性，對于下箱往往不加箱檔，以利于鑄件直接從砂箱脫出。這是不合理的。上下箱必須都設計抽氣箱檔，才能有效保障鑄型強度的均勻性及上下鑄型強度的對等性。圖9、圖10為某廠生產某種型號的鐵路側架鑄件的上下箱結構圖。另外值得一提的是，砂箱結構設計合理，對于同一套真空系統(tǒng)來講，可能同時允許接入的砂箱數(shù)量就會增加，意味著真空系統(tǒng)的利用效率明顯增強。</p><p> V法鑄造工藝設計簡介 </p> <p> 對于V法鑄造工藝的設計，不是只完成單個鑄件的工藝設計，應該是先完成單個鑄件的澆冒口系統(tǒng)、砂芯設計、透氣設計、冷鐵等的設計，然后，根據(jù)工廠現(xiàn)有V法裝備的實際和生產效率等進行模具的工藝布置設計，合理布置，重新進行澆注系統(tǒng)的優(yōu)化設計。之后進行模型體和型板上的抽氣塞設計(大小、位置、間距等設計)，抽氣塞的設計必須自行進行，不能交由模具設計和制作單位進行，抽氣塞設計是否合理對后續(xù)生產中的覆膜效果影響很大，同時影響生產中抽氣塞破損、堵塞后的更換。上述工作完成之后開始進行砂箱的設計工作，抽氣布局要合理，尤其是澆口和冒口附近，由于薄膜氣化和涂層受熱嚴重，真空泄漏較多，應在該部位增大真空抽氣量，保證該部位的負壓滿足實際需要。在進行砂箱設計時，不能只考慮真空度是否滿足，砂箱的負壓室容積必須保證足夠的抽氣量，否則，即便是真空度足夠，抽氣量不足同樣造成鑄型緊實率不足、砂型硬度不夠，澆注過程中甚至會由此產生砂型垮塌。 2008年時我國鑄鐵件廠產量達2510萬噸，其中按短流程工藝生產的鑄件約占11.3%。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚州質量V法鑄造原理,V法鑄造"

金屬液平穩(wěn)充型，避免沖刷鑄型或產生飛濺，一般采用底注半封閉式或開放式澆注系統(tǒng)。泰州實型V法鑄造原理</p><p style="text-indent:25px">生產表明，鑄型內負壓度大于0.044MPa時鑄型就可以保持足夠的強度和穩(wěn)定性。揚州質量V法鑄造原理</p><p> V法鑄造工藝過程和特點 </p> <p> 1 V法鑄造基本工藝過程 </p> <p> 制造帶有抽氣箱和抽氣孔模樣。 </p> <p> 烘烤薄膜并覆蓋到模樣上，抽負壓，使覆膜成形，后噴上快干涂料。 </p> <p> 將帶有過濾抽氣管的砂箱，放在已覆有薄膜的模板上。 </p> <p> 充填、振實、刮平箱內干砂，放上密封膜，抽負壓，使鑄型內外產生壓力差而緊實，。 </p> <p> 解除模樣內真空，起模。鑄型保持負壓狀態(tài)，直到下芯，合箱，澆鑄。 </p> <p> 脫箱落砂。冷卻后，將砂箱內的壓力恢復到常壓狀態(tài)，砂型自動潰散，鑄件保溫后取出，砂冷卻后返回系統(tǒng)循環(huán)使用，將鑄件取走進入清理工部完成工藝過程。揚州質量V法鑄造原理</p><p
