隨著V法鑄造向復(fù)雜結(jié)構(gòu)鑄件的延伸和拓展，原有的一維震實臺顯然已經(jīng)難以保障橫向縱深部位的填充緊實（見圖5），必須采用更為可靠的三維震實臺。但是部分企業(yè)始終意識不到這個問題，而因為這個問題而出現(xiàn)的粘砂或者尺寸失準(zhǔn)問題比比皆是。 </p> <p> <p> 起模機構(gòu)對鑄型質(zhì)量的影響 </p> <p> V法造型過程中，泰州真空V法鑄造特點，EVA薄膜與模具之間有一定的粘附力存在，泰州真空V法鑄造特點。再加上砂型的擠壓作用，泰州真空V法鑄造特點，使得起模過程中薄膜與模具之間存在明顯的摩擦。在提倡V法鑄造工藝少無拔模斜度的要求下，無疑對起模機構(gòu)的平穩(wěn)性有較為嚴(yán)格的要求。 </p> </p> <p> <br />

原輔材料對于鑄件質(zhì)量有直接的影響，重視原輔材料的使用，理解原輔材料對工藝過程及產(chǎn)品質(zhì)量的影響，對于提升鑄件質(zhì)量具有重要意義。V法鑄造工藝特別強調(diào)薄膜和涂料的使用控制，而耐磨鑄件本身對冒口補縮要求相對也較高，因此EVA薄膜，涂料，冒口等材料的使用技術(shù)在V法鑄造耐磨件方面比較關(guān)鍵。尤其是涂料的噴涂控制和烘干技術(shù)，冒口的安放及發(fā)氣量控制，不僅影響鑄件質(zhì)量，同時關(guān)系著生產(chǎn)作業(yè)效率和生產(chǎn)組織安排。另外，陶瓷管等其他輔助材料也將對鑄件沖砂和澆注安全性有著重要的影響。

alt="泰州真空V法鑄造特點,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889985097657/1146380.png"></div><p> V法鑄造工藝設(shè)計簡介 </p> <p> 對于V法鑄造工藝的設(shè)計，不是只完成單個鑄件的工藝設(shè)計，應(yīng)該是先完成單個鑄件的澆冒口系統(tǒng)、砂芯設(shè)計、透氣設(shè)計、冷鐵等的設(shè)計，然后，根據(jù)工廠現(xiàn)有V法裝備的實際和生產(chǎn)效率等進行模具的工藝布置設(shè)計，合理布置，重新進行澆注系統(tǒng)的優(yōu)化設(shè)計。之后進行模型體和型板上的抽氣塞設(shè)計(大小、位置、間距等設(shè)計)，抽氣塞的設(shè)計必須自行進行，不能交由模具設(shè)計和制作單位進行，抽氣塞設(shè)計是否合理對后續(xù)生產(chǎn)中的覆膜效果影響很大，同時影響生產(chǎn)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(shè)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(yán)重，真空泄漏較多，應(yīng)在該部位增大真空抽氣量，保證該部位的負(fù)壓滿足實際需要。在進行砂箱設(shè)計時，不能只考慮真空度是否滿足，砂箱的負(fù)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?xí)纱水a(chǎn)生砂型垮塌。 </p><p> 采用V法鑄造的原因 </p> <p> 根據(jù)國內(nèi)外經(jīng)驗來看，V法鑄造在耐磨鑄件上所具有的產(chǎn)品質(zhì)量高，環(huán)境友好的優(yōu)勢是人們選擇此工藝的重要原因之一。成本和環(huán)保方面的優(yōu)勢眾所周知，而質(zhì)量優(yōu)勢除了V法工藝本身具有的高表面質(zhì)量、高尺寸精度外，因為流動性的提升使得低溫澆注成為可能，可能會在細(xì)化晶粒提高耐磨性方面有一定的探索價值。 </p> <p> 我國鑄造企業(yè)數(shù)量多，整體鑄件質(zhì)量較低，鑄造企業(yè)所面臨的環(huán)保壓力、人力成本壓力越來越大，從提升產(chǎn)品質(zhì)量控制環(huán)境污染的角度，V法鑄造工藝有望在今后引起更好的關(guān)注和更***的應(yīng)用。3 V法鑄造工藝與水玻璃砂鑄造工藝耐磨內(nèi)部組織質(zhì)量對比及分析為了充分應(yīng)用好V法鑄造工藝，必須深刻認(rèn)識其工藝特性，尤其是局限性?；诖耍珖ＥcV法鑄造技術(shù)**會V法課題團隊在2014年針對V法鑄造工藝和水玻璃砂鑄造工藝生產(chǎn)的耐磨鑄件進行了內(nèi)部金相組織的對比，希望能夠為行業(yè)的發(fā)展提供一定借鑒和參考。干砂造型抽真空后減小了砂與砂之間的間隙，增加了砂與砂之間的摩擦力，提高砂強度。</p><div

耐火涂料的使用在V法鑄造中起到至關(guān)重要的作用。涂料層的性能不僅影響薄膜氣化氣體的遷移，而且與鑄件表面質(zhì)量密切相關(guān)。涂料載液一般選用乙醇、甲醇或異丙醇，綜合實踐一般選用乙醇含量大于95％的工業(yè)酒精，沸點為70℃，密度0．8g／cm，閃點12℃。V法鑄造用涂料應(yīng)具有以下基本要求： </p> <p> 不與塑料薄膜反應(yīng)，***無味； </p> <p> 具有好的懸浮性和強韌性，涂料層有高的透氣性及良好的抗機械滲透粘砂的能力； </p> <p> 較高耐火度，其中應(yīng)含有耐火度較高的礦物和耐火度相對較低、易燒結(jié)的組分，燒結(jié)形成剝離層，清理時易潰散； </p> <p> 要有較小的發(fā)氣量，良好的流動性和觸變性； </p> <p> 較高附著力，涂料能牢固的粘附在塑料薄膜上形成致密的涂層。穩(wěn)壓除塵濾氣罐。穩(wěn)壓罐主要作用是穩(wěn)定真空系統(tǒng)壓力，緩沖系統(tǒng)壓力波動對造型、澆注的影響。南通專業(yè)V法鑄造生產(chǎn)線</p><p

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(rèn)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(rèn)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(yán)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。泰州真空V法鑄造特點</p><p
