style="text-indent:25px">而鑄型不可能是完全密封的，始終處在一種氣體泄入并被抽走的過(guò)程中。顯然，南通真空密封V法鑄造工藝，距離抽氣口越近，氣體被抽速度越快，那么從氣流角度分析，越靠近砂箱四壁和抽氣管的地方，真空保持的越穩(wěn)定，強(qiáng)度也越高。澆注之前，外界氣體泄入量往往較小，會(huì)被及時(shí)抽走，不會(huì)對(duì)鑄型強(qiáng)度造成不利影響。但是，澆注過(guò)程中，隨著大面積薄膜的燒蝕，外界氣體泄入量劇增，如果泄入的氣體不能被及時(shí)抽走，鑄型內(nèi)部氣壓上升強(qiáng)度降低，南通真空密封V法鑄造工藝，就會(huì)造成塌箱。有時(shí)候盡管砂箱已經(jīng)有四壁抽氣甚至還有少量抽氣箱帶或者抽氣管，南通真空密封V法鑄造工藝，而且真空度還很高，仍然會(huì)塌箱。國(guó)家環(huán)保的壓力更是推動(dòng)了部分不符合標(biāo)準(zhǔn)的小企業(yè)加快了這一實(shí)驗(yàn)的腳步。南通真空密封V法鑄造工藝</p><div

與傳統(tǒng)濕型相比，V法砂型少無(wú)型壁移動(dòng)，其硬度可達(dá)90—95，由于干砂保溫時(shí)間長(zhǎng)，冒口體積可減少5%—15%。因此V法鑄造可提高金屬液的利用率（球墨鑄鐵件提高約25%，鑄鋼件提高約20%）。V法鑄造適合生產(chǎn)球墨鑄鐵鑄件，也適合生產(chǎn)鑄鋼件。圖4為V法鑄造的球墨鑄鐵后橋。圖5為我國(guó)天瑞集團(tuán)鑄造有限公司V法鑄造的鐵道機(jī)車(chē)鑄鋼側(cè)架。 </p> <p> V法砂型處于真空，不含水份，保溫性能好，很適合生產(chǎn)小批量少無(wú)內(nèi)腔的鋁合金鑄件。日本曾采用大型V法造型機(jī)和超大砂箱（7000 mm×4000mm×1000/800mm）生產(chǎn)出鑄鋁游艇殼體（見(jiàn)圖6）。烏克蘭、荷蘭和美國(guó)等數(shù)家鑄造企業(yè)采用V法生產(chǎn)醫(yī)療，電子，通訊等行業(yè)用的小型鋁鑄件，其鑄件表面質(zhì)量可與金屬型鑄鋁件媲美。圖7為美國(guó)Harmony Casting公司采用V法生產(chǎn)的鑄鋁件，大平面厚度為4.7mm，局部薄至2.3mm。南京質(zhì)量V法鑄造工藝而鑄鋼件多采用開(kāi)放式澆注系統(tǒng)，其澆道截面積比例為F直∶F橫∶F內(nèi)＝1∶(1．2～2)∶(1．2～2) ；</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">微觀上來(lái)講，砂型強(qiáng)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(duì)砂子有較強(qiáng)的摩擦力，也就加強(qiáng)了其附近砂型的強(qiáng)度。某廠在采用V法工藝生產(chǎn)球鐵橋殼過(guò)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(qiáng)度及剛性不足，完全抵擋不住球墨鑄**固過(guò)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(shí)分型面產(chǎn)生極大的飛邊，致使鑄件報(bào)廢。砂箱及鑄件如圖8所示。江陰華天科技開(kāi)發(fā)有限公司坐落于中國(guó)經(jīng)濟(jì)發(fā)達(dá)的長(zhǎng)江三角洲經(jīng)濟(jì)區(qū)中心的江蘇省江陰市，專(zhuān)業(yè)從事氣力輸送系統(tǒng)，V法、消失模、樹(shù)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(jì)制造、安裝調(diào)試。</p><p> V法鑄造在國(guó)外的發(fā)展 </p> <p> 據(jù)1991年日本V法鑄造分會(huì)統(tǒng)計(jì)，日本從事V法鑄造的企業(yè)達(dá)149家，歐洲V法鑄造企業(yè)達(dá)40家，北美共有31家。據(jù)1995年Modern Casting統(tǒng)計(jì)，日本有180家V法企業(yè)，美國(guó)有10家，歐洲有85家?？梢?jiàn)20世紀(jì)90年代，V法鑄造因其固體廢棄物**少，符合節(jié)能減排的要求，在發(fā)達(dá)國(guó)家受到青睞并獲得迅猛發(fā)展。進(jìn)入21世紀(jì)后，雖然V法鑄造在發(fā)達(dá)國(guó)家出現(xiàn)萎縮，但V法技術(shù)在新興國(guó)家得到長(zhǎng)足發(fā)展。

干燥良好的無(wú)缺點(diǎn)木材是V法鑄造常用模具材料。金屬材料價(jià)格昂貴，而且鉆孔較困難，并不太適合用于V法模具。另外暴露于薄膜加熱器下的金屬模具受重復(fù)加熱作用，溫度上升后易粘薄膜。因此V法鑄造企業(yè)長(zhǎng)期采用木質(zhì)材料制模，而其大多是靠模型工放樣半機(jī)械化制作。其尺寸精度較差和生產(chǎn)周期較長(zhǎng)一直是V法鑄造的瓶頸。南通真空密封V法鑄造工藝</p><p
