耐火涂料的使用在V法鑄造中起到至關(guān)重要的作用。涂料層的性能不*影響薄膜氣化氣體的遷移，而且與鑄件表面質(zhì)量密切相關(guān)。涂料載液一般選用乙醇、甲醇或異丙醇，綜合實(shí)踐一般選用乙醇含量大于95％的工業(yè)酒精，揚(yáng)州質(zhì)量V法鑄造生產(chǎn)線，沸點(diǎn)為70℃，密度0．8g／cm，閃點(diǎn)12℃。V法鑄造用涂料應(yīng)具有以下基本要求： </p> <p> 不與塑料薄膜反應(yīng)，***無味； </p> <p> 具有好的懸浮性和強(qiáng)韌性，涂料層有高的透氣性及良好的抗機(jī)械滲透粘砂的能力； </p> <p> 較高耐火度，其中應(yīng)含有耐火度較高的礦物和耐火度相對較低、易燒結(jié)的組分，燒結(jié)形成剝離層，清理時(shí)易潰散； </p> <p> 要有較小的發(fā)氣量，良好的流動(dòng)性和觸變性； </p> <p> 較高附著力，揚(yáng)州質(zhì)量V法鑄造生產(chǎn)線，涂料能牢固的粘附在塑料薄膜上形成致密的涂層。但澆注時(shí)負(fù)壓度的變化大，揚(yáng)州質(zhì)量V法鑄造生產(chǎn)線，澆注瞬間，負(fù)壓度下降快，澆注完畢后鑄型能恢復(fù)并保持較高的負(fù)壓度。揚(yáng)州質(zhì)量V法鑄造生產(chǎn)線</p><div

style="text-indent:25px">鑄型強(qiáng)度不夠或者不均勻，在有些具有大平面特點(diǎn)的鑄件生產(chǎn)上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時(shí)候常常為了落砂的簡易性，對于下箱往往不加箱檔，以利于鑄件直接從砂箱脫出。這是不合理的。上下箱必須都設(shè)計(jì)抽氣箱檔，才能有效保障鑄型強(qiáng)度的均勻性及上下鑄型強(qiáng)度的對等性。圖9、圖10為某廠生產(chǎn)某種型號的鐵路側(cè)架鑄件的上下箱結(jié)構(gòu)圖。另外值得一提的是，砂箱結(jié)構(gòu)設(shè)計(jì)合理，對于同一套真空系統(tǒng)來講，可能同時(shí)允許接入的砂箱數(shù)量就會(huì)增加，意味著真空系統(tǒng)的利用效率明顯增強(qiáng)。南京V法鑄造裝備實(shí)際生產(chǎn)中，一般依據(jù)真空罐上的真空表及砂箱外管道上的真空表反映的負(fù)壓度來調(diào)節(jié)生產(chǎn)時(shí)的負(fù)壓度。</p><div

style="text-indent:25px">V法鑄造（真空密封造型）是七十年代初由日本首先發(fā)明，之后經(jīng)美國，歐洲各國鑄造**研究，確立了V法造型的比較好和**基本方法。目前這種新穎鑄造方法已***使用在鑄鐵、鑄鋼、有色鑄造行業(yè)中，鑄件的重量從幾克到重達(dá)幾十噸。近年來中國V法鑄造形勢獨(dú)好，據(jù)統(tǒng)計(jì)2010年全國V法鑄造企業(yè)超過200余家，其中十余條是引進(jìn)日本和德國真空密封造型線設(shè)備和技術(shù)。V法鑄造因鑄件表面質(zhì)量好、尺寸精度高，工藝操作簡便，金屬利用率高，生產(chǎn)成本低，適用范圍廣，在質(zhì)量、技術(shù)和經(jīng)濟(jì)效益方面有***的競爭優(yōu)勢。本文著重介紹V法鑄造生產(chǎn)過程﹑質(zhì)量控制和技術(shù)控制的措施和方法。</p><p> 20世紀(jì)7o年代末我國有十余家企業(yè)引進(jìn)了日本和德國V法鑄造設(shè)備和技術(shù)，提升了我國V法鑄造水平。據(jù)粗略統(tǒng)計(jì)，國內(nèi)現(xiàn)有v法鑄造企業(yè)近200家，主要分布在山西、江蘇、安徽、山東和河北等地。江陰華天科技開發(fā)有限公司為青島四海電力鑄造廠設(shè)計(jì)一種固定式簡易V法造型機(jī)，它是鋼結(jié)構(gòu)焊接而成，由底座支撐架、震實(shí)臺、負(fù)壓箱、頂箱機(jī)構(gòu)等組成，具有結(jié)構(gòu)新穎、外形美觀、運(yùn)行可靠的特點(diǎn)。震實(shí)臺由四組頂桿同步，將砂箱平穩(wěn)地與模型分離。頂箱機(jī)的控制設(shè)有就地電控箱，人工操作，便于掌握起模時(shí)間。這種V法造型機(jī)機(jī)構(gòu)簡單，更換模板方便，人工操作與機(jī)械化造型相結(jié)合，投資少，上馬快，比較適合單件、小批量鑄造車間使用，生產(chǎn)中、小型V法鑄件。面有所突破。

V法工藝是70年代初發(fā)明的一種新的鑄造工藝方法，近幾年在我國應(yīng)用發(fā)展的很快，已從鑄造叉車配重、浴盆等鑄鐵鑄件發(fā)展到鑄鋼、鑄銅、鑄鋁加工件。但是一些形狀比較復(fù)雜的鑄件給覆膜帶來困難，有的需配多件砂芯。影響了造型效率，增加成本，使V法鑄造工藝的推廣應(yīng)用受到限制。 </p> <p> 我們是推廣應(yīng)用V法鑄造工藝和消失模鑄造工藝的企業(yè)。我們在推廣過程中發(fā)現(xiàn)，將兩種工藝結(jié)合在一起，取長補(bǔ)短，可以簡化覆膜，提高覆膜質(zhì)量，提高鑄件質(zhì)量，減薄EVA薄膜厚度，減少砂芯用量，提高造型效率，降低V法鑄造成本，效果明顯。我們在應(yīng)用上進(jìn)行一些探討，試用，取得了明顯的效果。我們將這一工藝叫做《消失模鑄造工藝嫁接到V法鑄造工藝的新方法》供同行們參考，共同開發(fā)這一工藝。揚(yáng)州質(zhì)量V法鑄造生產(chǎn)線</p><p
