關(guān)于V法鑄造工藝優(yōu)勢的討論國外典型耐磨鑄件生產(chǎn)企業(yè)實踐證明V法鑄造工藝在耐磨鑄件的生產(chǎn)上是成功的，也是有優(yōu)勢的。具體優(yōu)勢如下： </p> <p> 1產(chǎn)品質(zhì)量方面 </p> <p> V法鑄造鑄件表面質(zhì)量好，光潔度高；產(chǎn)品尺寸精度高，尤其是中大型鑄件批量化生產(chǎn)條件下的尺寸穩(wěn)定性更具優(yōu)勢；產(chǎn)品輪廓清晰，可實現(xiàn)少無拔模斜度；鋼水流動性好，可實現(xiàn)低溫度澆注，作為提高鑄件晶粒度等級，提高耐磨性的潛在手段之一； </p> <p> 2生產(chǎn)管理方面 </p> <p> V法鑄造工藝的成本更低，單位鑄件重量能耗和輔材消耗低，勞動強度低；采用干砂造型無需混砂等過程，設(shè)備投資少，砂處理簡單，舊砂回用率較高，不存在廢砂廢水等污染情況；模具磨損小，揚州真空密封V法鑄造裝備，揚州真空密封V法鑄造裝備，壽命高；高自動化程度生產(chǎn)線生產(chǎn)效率高，人均產(chǎn)量高；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，揚州真空密封V法鑄造裝備，緩沖系統(tǒng)壓力波動對造型、澆注的影響。揚州真空密封V法鑄造裝備</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="揚州真空密封V法鑄造裝備,V法鑄造"

style="text-indent:25px">微觀上來講，砂型強度是靠砂子之間以及砂子與砂箱直接的摩擦力建立的。砂箱四壁和箱帶都對砂子有較強的摩擦力，也就加強了其附近砂型的強度。某廠在采用V法工藝生產(chǎn)球鐵橋殼過程中，由于砂箱未加箱檔或抽氣管，盡管系統(tǒng)真空度較高，但是鑄型強度及剛性不足，完全抵擋不住球墨鑄**固過程中的石墨化膨脹，嚴(yán)重脹箱，造成鑄件內(nèi)部組織致密性不夠，同時分型面產(chǎn)生極大的飛邊，致使鑄件報廢。砂箱及鑄件如圖8所示。江陰華天科技開發(fā)有限公司坐落于中國經(jīng)濟(jì)發(fā)達(dá)的長江三角洲經(jīng)濟(jì)區(qū)中心的江蘇省江陰市，專業(yè)從事氣力輸送系統(tǒng)，V法、消失模、樹脂砂、水玻璃砂鑄造設(shè)備，輸送設(shè)備及環(huán)保設(shè)備的設(shè)計制造、安裝調(diào)試。揚州真空密封V法鑄造裝備四工位造型機的旋轉(zhuǎn)由氣缸驅(qū)動，并有可靠的定位機構(gòu)，整機動作采用可編程控制器（即PC）程序控制。</p><div

src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889370097657/738567.png"></div><p> 國內(nèi)V法薄膜生產(chǎn)企業(yè)主要有武漢恒德科技有限公司、北京華盾塑料公司、天津市萊沃商貿(mào)有限公司等。其中，武漢恒德科技有限公司是我國比較大的V法**EVA薄膜生產(chǎn)企業(yè)，該公司現(xiàn)有4條生產(chǎn)線，具備日產(chǎn)12 t不同規(guī)格EVA薄膜的能力。 </p> <p> 該公司不斷改進(jìn)基于EVA的V法**膜，其醋酸乙烯含量(質(zhì)量分?jǐn)?shù)，下同)為18%-20%，維卡軟化點為70℃。添加山茶植物油提煉的外潤滑劑等輔料，使其伸長率較高，縱向達(dá)到717 % ,橫向達(dá)到589，接近日本同類產(chǎn)品。目前，V法鑄造用EVA鑄型薄膜的行業(yè)標(biāo)準(zhǔn)正在制訂中。 </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(jìn)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(jìn)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(jìn)一步局限了V法鑄造工藝的普及和進(jìn)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(jì)效益。真空密封造型緊實原理是利用塑料薄膜密封砂箱，依靠真空抽出型內(nèi)的空氣造成鑄型內(nèi)外壓力差使干砂緊實。</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(jìn)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。合理的鑄造工藝方案是保證覆膜成型和鑄件質(zhì)量的一個重要因素。南京專業(yè)V法鑄造設(shè)備廠</p><p
