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。

對(duì)于V法鑄造工藝的設(shè)計(jì)，不是只完成單個(gè)鑄件的工藝設(shè)計(jì)，應(yīng)該是先完成單個(gè)鑄件的澆冒口系統(tǒng)、砂芯設(shè)計(jì)、透氣設(shè)計(jì)、冷鐵等的設(shè)計(jì)，然后，根據(jù)工廠現(xiàn)有V法裝備的實(shí)際和生產(chǎn)效率等進(jìn)行模具的工藝布置設(shè)計(jì)，合理布置，重新進(jìn)行澆注系統(tǒng)的優(yōu)化設(shè)計(jì)。之后進(jìn)行模型體和型板上的抽氣塞設(shè)計(jì)(大小、位置、間距等設(shè)計(jì))，抽氣塞的設(shè)計(jì)必須自行進(jìn)行，不能交由模具設(shè)計(jì)和制作單位進(jìn)行，抽氣塞設(shè)計(jì)是否合理對(duì)后續(xù)生產(chǎn)中的覆膜效果影響很大，同時(shí)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(jìn)行砂箱的設(shè)計(jì)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(shí)際需要。在進(jìn)行砂箱設(shè)計(jì)時(shí)，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(shí)率不足、砂型硬度不夠，澆注過(guò)程中甚至?xí)纱水a(chǎn)生砂型垮塌。而鑄鋼件多采用開放式澆注系統(tǒng)，其澆道截面積比例為F直∶F橫∶F內(nèi)＝1∶(1．2～2)∶(1．2～2) ；泰州真空密封V法鑄造設(shè)備廠</p><p style="text-indent:25px">型砂粒度對(duì)鑄型負(fù)壓度變化的影響很大，較細(xì)的型砂有利于防止金屬液滲透。南京專業(yè)V法鑄造生產(chǎn)線</p><p> 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)車鑄鋼側(cè)架。
