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?0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。 </p> <p> V法鑄造設(shè)備大型化和小型化并進(jìn) </p> <p> 目前世界比較大的V法鑄造設(shè)備公司是德國(guó)Heinrich Wagner公司與日本Sinto(新東)公司組建的Heinrich Wagner-Sinto，簡(jiǎn)稱HWS(豪斯)公司。2004年分別在俄羅斯和烏克蘭建成4工位轉(zhuǎn)盤式大型V法鑄造線，每小時(shí)生產(chǎn)20型，砂箱尺寸為3 000 mm X1 800 mmX 500 mm/500 mm，每條造型線年產(chǎn)10萬(wàn)t鐵路車輛的關(guān)鍵鑄鋼部件搖枕和側(cè)架。 </p> <p> <br /> </p><p> V法鑄造工藝過(guò)程和特點(diǎn) </p> <p> 1 V法鑄造基本工藝過(guò)程 </p> <p> 制造帶有抽氣箱和抽氣孔模樣。 </p> <p> 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(guò)濾抽氣管的砂箱，放在已覆有薄膜的模板上。 </p> <p> 充填、振實(shí)、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(shí)，。 </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(dòng)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(guò)程。正確選擇真空泵以及合理的真空系統(tǒng)是保證V法鑄型穩(wěn)定負(fù)壓度的前提。</p><div style="width:100%;text-align:
