以砂箱的周轉為例，耐磨鑄件由于保溫冷卻時間長，在一定程度上限制了砂箱的流轉速度，企業(yè)訂購大量砂箱不僅**增加了企業(yè)成本，而且造成管理使用上的困難。可通過采用建設冷卻立體庫，南通先進V法鑄造生產線，設計冷卻托盤的方式加快砂箱流轉，同時節(jié)約生產場地。標準化托盤的設計和制作，南通先進V法鑄造生產線，滿足叉車運輸條件，并不額外增加過多的勞動力，實現了工藝生產的要求，降低了設備投資成本，同時提高的系統(tǒng)運行效率。除塵濾氣罐采用介質分離，抽吸進來的氣體與水混合。南通先進V法鑄造生產線</p><div

style="text-indent:25px">鑄型強度不夠或者不均勻，在有些具有大平面特點的鑄件生產上，不能很好的減小或防止鑄件在冷卻過程中的變形。有時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。上下箱必須都設計抽氣箱檔，才能有效保障鑄型強度的均勻性及上下鑄型強度的對等性。圖9、圖10為某廠生產某種型號的鐵路側架鑄件的上下箱結構圖。另外值得一提的是，砂箱結構設計合理，對于同一套真空系統(tǒng)來講，可能同時允許接入的砂箱數量就會增加，意味著真空系統(tǒng)的利用效率明顯增強。揚州先進V法鑄造設備廠目前國內有十多個在建的鑄造工業(yè)園區(qū)，均采用高爐—感應爐供應鐵液，年產鑄件達100多萬噸。</p><div

通過工藝試驗過程的開展，理解耐磨鑄件V法鑄造工藝路線，熟知工藝控制要點及比較好工藝參數，對于V法鑄造項目的順利開展具有重要意義。V法鑄造在國內推廣早期，上述環(huán)節(jié)的缺失為不少企業(yè)釀成了重大損失，目前逐漸引起越來越多企業(yè)的重視。尤其是真空的使用和控制是V法鑄造工藝有別于傳統(tǒng)砂型鑄造的重要特征，深刻的影響著產品質量和生產管理過程的控制等。從國外耐磨企業(yè)案例不難看出，在其探索過程中，同樣經過了足夠的產品生產試驗，從單件到小批量，從簡易工藝設備到大型生產線，在充分分析工藝過程的基礎上，對相應V法工藝裝備及生產線有了更充分的認識和風險預判，為后續(xù)的批量化生產奠定了基礎。 </p><p 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幾十噸。近年來中國V法鑄造形勢獨好，據統(tǒng)計2010年全國V法鑄造企業(yè)超過200余家，其中十余條是引進日本和德國真空密封造型線設備和技術。V法鑄造因鑄件表面質量好、尺寸精度高，工藝操作簡便，金屬利用率高，生產成本低，適用范圍廣，在質量、技術和經濟效益方面有***的競爭優(yōu)勢。本文著重介紹V法鑄造生產過程﹑質量控制和技術控制的措施和方法。降低咯鑄型的透氣性，較粗的型砂，可提高鑄型的透氣性。</p><div

與傳統(tǒng)濕型相比，V法砂型少無型壁移動，其硬度可達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法鑄造適合生產球墨鑄鐵鑄件，也適合生產鑄鋼件。圖4為V法鑄造的球墨鑄鐵后橋。圖5為我國天瑞集團鑄造有限公司V法鑄造的鐵道機車鑄鋼側架。 </p> <p> V法砂型處于真空，不含水份，保溫性能好，很適合生產小批量少無內腔的鋁合金鑄件。日本曾采用大型V法造型機和超大砂箱（7000 mm×4000mm×1000/800mm）生產出鑄鋁游艇殼體（見圖6）。烏克蘭、荷蘭和美國等數家鑄造企業(yè)采用V法生產醫(yī)療，電子，通訊等行業(yè)用的小型鋁鑄件，其鑄件表面質量可與金屬型鑄鋁件媲美。圖7為美國Harmony Casting公司采用V法生產的鑄鋁件，大平面厚度為4.7mm，局部薄至2.3mm。分析砂溫對砂處理設備設計和鑄件質量控制的影響，從而科學和適宜地進行砂溫控制。揚州先進V法鑄造設備廠</p><p style="text-indent:25px">對于V法鑄造企業(yè)，結合企業(yè)生產和產品特點、V法鑄造特性及其主輔材料的功用。南通先進V法鑄造生產線</p><p> V法鑄造工藝流程 </p> <p> <span style="font-size:12px;">其流程如下。</span> </p> <p> 1．加熱薄膜并覆膜 </p> <p> (1)薄膜材質EVA。 </p> <p> (2)薄膜厚度0.15mm。 </p> <p> (3)加熱溫度80~120℃。 </p> <p> (4)吸氣壓強：26.7~53.4kPa。 </p> <p> 2．放置澆注系統(tǒng)并加冒口 </p> <p> (1)直澆道為進口陶管，用膠帶粘到模樣上并密封。 </p> <p> (2)冒口為木頭，用塑料包好并用膠帶纏到模樣上密封好。 </p> <p> (3)澆道和冒口都要密封好，已放置漏氣不能很好覆膜。 </p> <p> (4)澆道和冒口與模樣的連接處用刀子切口，便于后期澆注是排氣。 </p> <p> 3．噴涂料并等待涂料干燥 </p> <p> （1）涂料成分：重量比為50%的工業(yè)酒精與50%的滑石粉混合的懸濁液。 </p> <p> （2）噴漆厚度：0.04mm。 </p> <p> （3）使用要求：噴涂均勻，個別地方要補刷涂料；噴涂后要等待涂料烘干再放砂。南通先進V法鑄造生產線</p><p
