與傳統(tǒng)濕型相比，V法砂型少無型壁移動，其硬度可達(dá)90—95，由于干砂保溫時間長，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為我國天瑞集團(tuán)鑄造有限公司V法鑄造的鐵道機(jī)車鑄鋼側(cè)架。 </p> <p> V法砂型處于真空，不含水份，南通先進(jìn)V法鑄造企業(yè)，南通先進(jìn)V法鑄造企業(yè)，保溫性能好，很適合生產(chǎn)小批量少無內(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（見圖6）。烏克蘭、荷蘭和美國等數(shù)家鑄造企業(yè)采用V法生產(chǎn)醫(yī)療，南通先進(jìn)V法鑄造企業(yè)，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。涂料是保證鑄件表面質(zhì)量，防止粘砂的關(guān)鍵；南通先進(jìn)V法鑄造企業(yè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

烘烤薄膜并覆蓋到模樣上，抽負(fù)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(nèi)干砂，放上密封膜，抽負(fù)壓，使鑄型內(nèi)外產(chǎn)生壓力差而緊實，。 </p> <p> 解除模樣內(nèi)真空，起模。鑄型保持負(fù)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(nèi)的壓力恢復(fù)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(jìn)入清理工部完成工藝過程。南通先進(jìn)V法鑄造企業(yè)除塵濾氣罐的主要作用是防止細(xì)砂和粉塵進(jìn)入泵內(nèi)，磨損機(jī)械零件，影響泵的正常工作。</p><div

style="text-indent:25px">對于一些多筋板或具有相當(dāng)高垂直面的鑄件而言，這種擦傷鑄型的現(xiàn)象尤為普遍。而個別自動化程度很高的機(jī)械手，運轉(zhuǎn)穩(wěn)定性差，末端柔性不足，在運轉(zhuǎn)過程中產(chǎn)生震蕩或者難以急停，甚至不能保證**起碼的定位及真空對接精度，直接影響鑄型在起模翻轉(zhuǎn)等過程中的安全性。隨著V法成套裝備生產(chǎn)線自動化和機(jī)械化水平的提升，對起模機(jī)構(gòu)的使用要求越來越高。這就需要我們在這些關(guān)鍵的造型設(shè)備方面，提高設(shè)計，制造，安裝的精度和可靠性，以充分保障造型質(zhì)量和鑄型安全。</p><p style="text-indent:25px">微觀上來講，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。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(qiáng)度。</p><div
