砂芯的設(shè)計主要是排氣問題，在砂芯的分芯面上開挖排氣和集氣通道，泰州質(zhì)量V法鑄造設(shè)備，在這些通道上扎制砂芯內(nèi)部排氣孔，再將這些排氣和集氣通道進行匯集，通過匯集點向鑄型外排出，使得砂芯內(nèi)氣體有效排出型外，避免氣孔和鑄件內(nèi)壁氧化等缺點。 </p> <p> <br /> </p> <p> <br /> </p> <p> 5.澆注速度、真空保持時間的設(shè)計 </p> <p> 由于V法鑄造的真空特點，澆注過程中，外型和坭芯均處于真空狀態(tài)，其澆注充型的能力遠大于其它鑄造工藝，泰州質(zhì)量V法鑄造設(shè)備。鑒于V法鑄造冷卻緩慢和真空特性，澆注溫度不宜偏高，泰州質(zhì)量V法鑄造設(shè)備，目的是為了避免或減弱收縮類缺點。 </p> <p> 在通氣和排氣系統(tǒng)適當?shù)那闆r下，在澆注末期透氣孔不出現(xiàn)“嗆火”狀態(tài)下可以提高澆注速度，滿足產(chǎn)品質(zhì)量前提下，可以在平常澆注速度的基礎(chǔ)上提高20%～30%;澆注終了的點澆等與其它工藝相同。實際生產(chǎn)中，一般依據(jù)真空罐上的真空表及砂箱外管道上的真空表反映的負壓度來調(diào)節(jié)生產(chǎn)時的負壓度。泰州質(zhì)量V法鑄造設(shè)備</p><div

國內(nèi)耐磨鑄件生產(chǎn)企業(yè)對于V法鑄造工藝的理解、認識及深層次的研究有限，對V法鑄造工藝的引入和采用相對比較盲目，缺乏循序漸進的過程；在未經(jīng)過基本的工藝過程試驗和未對裝備系統(tǒng)進行必要充足認識的基礎(chǔ)上，引入和建設(shè)的裝備及生產(chǎn)線難以很好滿足耐磨件V法鑄造工藝生產(chǎn)的要求，**終使得配套工裝設(shè)施勉強適應(yīng)工藝生產(chǎn)的需要，造成生產(chǎn)質(zhì)量上的問題及生產(chǎn)管理上的麻煩。 </p> <p> 4.2我國國內(nèi)耐磨鑄件市場龐大，生產(chǎn)企業(yè)多，無序競爭嚴重；耐磨鑄造企業(yè)普遍存在產(chǎn)品種類多、批量小的特點，這進一步局限了V法鑄造工藝的普及和進步。主要原因在于上述特點使得企業(yè)在采用V法鑄造工藝生產(chǎn)時面臨著較高的模具成本投入，裝備通用性設(shè)計難度增加，難以實現(xiàn)批量生產(chǎn)。反觀國外一些較大的企業(yè)，生產(chǎn)集中度較高，存在批量生產(chǎn)的條件，從而在V法鑄造的使用中獲得了較好的經(jīng)濟效益。無錫實型V法鑄造流程合理的澆注系統(tǒng)及澆注速度是防止產(chǎn)生脹砂、塌箱、增厚等缺點的關(guān)鍵措施；</p><div

</p><p style="text-indent:25px">V法工藝生產(chǎn)耐磨鑄件的發(fā)展V法鑄造1973年起源于日本，80年代引入中國后得到了***關(guān)注，并逐步應(yīng)用于很多產(chǎn)品的生產(chǎn)。同時，該工藝傳入北美及歐洲地區(qū)，取得了長足發(fā)展，應(yīng)用范圍不斷擴展，在叉車配重、工程機械橋殼、浴盆等領(lǐng)域獲得了非常成熟的應(yīng)用。在耐磨鑄件領(lǐng)域，V法鑄造工藝在瑞典山特維克、美國耐磨狼、美伊電鋼等**耐磨鑄件生產(chǎn)企業(yè)的使用中獲得了極大成功，并逐步成為這些企業(yè)的主流工藝。在國內(nèi)，從上世紀80年代開始有初步探索該工藝生產(chǎn)耐磨鑄件的試驗，但是沒有成熟應(yīng)用（除鐵路道岔外）。近些年，在耐磨鑄件生產(chǎn)領(lǐng)域，V法鑄造工藝重新得到重視和關(guān)注。目前，V法鑄造在耐磨鑄件的生產(chǎn)應(yīng)用方面主要以傳統(tǒng)礦山耐磨鑄件為主，包括高錳鋼圓錐、齒板、錘頭、板錘、大型襯板等。甚至有些企業(yè)成功將立磨所用高鉻輥套鑄件采用V法鑄造工藝生產(chǎn)，取得了不錯的效果。對于V法鑄造企業(yè)，結(jié)合企業(yè)生產(chǎn)和產(chǎn)品特點、V法鑄造特性及其主輔材料的功用。</p><div

style="text-indent:25px">覆膜架帶動EVA薄膜下降過程中與空氣產(chǎn)生的對流運動必然形成對整張薄膜的浮力，進而造成薄膜的向上運動，并使薄膜自身產(chǎn)生一定的張力，即薄膜內(nèi)部區(qū)域?qū)ν獠繀^(qū)域的拉力作用（見圖1）。根據(jù)空氣動力學(xué)原理，對流速度越快，也就是覆膜架下降的速度越快，這種浮力越大，整張薄膜向上浮動的速度也就越大，同時，對薄膜的拉伸作用也越明顯。這種浮力不但會使EVA薄膜容易上浮并接觸到紅熱的電熱絲或者電熱管燙破，也有可能使熱態(tài)強度很低的薄膜在拉力作用下直接拉裂；采用數(shù)學(xué)模型去定量的給出覆膜框下行速度的參考值是很困難的，因為柔性極強的薄膜在覆膜框帶動下運動的受力狀態(tài)極其復(fù)雜，直接的生產(chǎn)調(diào)試控制速度過快是比較現(xiàn)實的辦法。值得注意的是，覆膜架下行過程中加速度太大會造成EVA薄膜強烈顫動，這往往源于氣動控制裝置穩(wěn)定性太差、速度變化過分強烈。這種不必要的震蕩對于熱態(tài)下強度很低的薄膜也是非常危險的。圖2為某生產(chǎn)現(xiàn)場因為覆膜框震蕩造成EVA薄膜破裂的現(xiàn)象。V法鑄造中多采用干式真空泵和水環(huán)真空泵，我國主要采用水環(huán)式真空泵。無錫實型V法鑄造流程</p><p

style="text-indent:25px">V法鑄造用的砂箱，其結(jié)構(gòu)形式直接決定著砂箱內(nèi)負壓場的形成和分布，也就決定著鑄型強度的大小和均勻性。但是，不少觀念錯誤的認為，只要砂箱里面能夠抽氣就行，至于怎么抽，抽多少，都無關(guān)緊要，只要不塌箱即可。所以目前，既有單純的抽氣管抽氣的砂箱，也有靠四壁抽氣的砂箱，**復(fù)雜的則有四壁抽氣并外加箱帶或抽氣管輔助的形式；似乎都達到了同樣的目的，都能生產(chǎn)出鑄件。然而，產(chǎn)生的影響卻是不一樣的。生產(chǎn)上習(xí)慣了用真空度來衡量或者表征鑄型的強度，認為真空度越高，鑄型強度越高，塌箱的幾率也越??；實際上，對于砂箱來說，真空的形成是氣體流動的結(jié)果，是型腔內(nèi)的空氣被真空系統(tǒng)抽走之后形成的。泰州質(zhì)量V法鑄造設(shè)備</p><p
