<p> 根據(jù)國(guó)內(nèi)外經(jīng)驗(yàn)來看，V法鑄造在耐磨鑄件上所具有的產(chǎn)品質(zhì)量高，環(huán)境友好的優(yōu)勢(shì)是人們選擇此工藝的重要原因之一。成本和環(huán)保方面的優(yōu)勢(shì)眾所周知，而質(zhì)量?jī)?yōu)勢(shì)除了V法工藝本身具有的高表面質(zhì)量、高尺寸精度外，因?yàn)榱鲃?dòng)性的提升使得低溫澆注成為可能，可能會(huì)在細(xì)化晶粒提高耐磨性方面有一定的探索價(jià)值。 </p> <p> 我國(guó)鑄造企業(yè)數(shù)量多，整體鑄件質(zhì)量較低，鑄造企業(yè)所面臨的環(huán)保壓力、人力成本壓力越來越大，從提升產(chǎn)品質(zhì)量控制環(huán)境污染的角度，V法鑄造工藝有望在今后引起更好的關(guān)注和更***的應(yīng)用。3 V法鑄造工藝與水玻璃砂鑄造工藝耐磨內(nèi)部組織質(zhì)量對(duì)比及分析為了充分應(yīng)用好V法鑄造工藝，必須深刻認(rèn)識(shí)其工藝特性，尤其是局限性?；诖?，全國(guó)消失模與V法鑄造技術(shù)**會(huì)V法課題團(tuán)隊(duì)在2014年針對(duì)V法鑄造工藝和水玻璃砂鑄造工藝生產(chǎn)的耐磨鑄件進(jìn)行了內(nèi)部金相組織的對(duì)比，希望能夠?yàn)樾袠I(yè)的發(fā)展提供一定借鑒和參考。無錫覆膜砂V法鑄造價(jià)格開設(shè)補(bǔ)縮冒口須根據(jù)砂型鑄造工藝原則、V法鑄造工藝特點(diǎn)及鑄件特點(diǎn)等具體確定。</p><div

style="text-indent:25px">一般認(rèn)為V法鑄造不適宜做中小型鑄件，*適合大型簡(jiǎn)單鑄鐵件，如配重鐵和浴盆等?？蒆WS公司設(shè)計(jì)出適合于中小型鑄鐵件的V法環(huán)形自動(dòng)化生產(chǎn)線，有效地提高了中小件的生產(chǎn)效率。中等鑄型生產(chǎn)線多采用水平分型，砂箱尺寸為800 mm X 800 mm X 200mm/200 mm。每2-v3 min造一箱，耗砂量為12 m3/h。砂箱排列成環(huán)形軌道。而小型鑄件生產(chǎn)線則采用垂直分型，砂箱呈垂直環(huán)形排列，鑄型尺寸為600 mm X 600mmX 150 mm，在環(huán)形輸送帶上放置29個(gè)砂箱，其中8個(gè)砂箱位于澆注臺(tái)、1個(gè)砂箱位于下芯工作臺(tái)，耗砂量為14 m3/h，生產(chǎn)率達(dá)到90一150箱/h，垂直分型造型線布置見圖1。整套系統(tǒng)由兩個(gè)薄膜加熱器、一個(gè)同時(shí)制造兩半鑄型的填砂造型臺(tái)、鑄型輸送轉(zhuǎn)臺(tái)等組成。</p><p> (4) 與傳統(tǒng)濕型相比，V法砂型少無型壁移動(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。 </p> <p> V法砂型處于真空，不含水份，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(guó)等數(shù)家鑄造企業(yè)采用V法生產(chǎn)醫(yī)療，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(guó)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。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: center;"><img style="max-width: 640px; max-height: 320px;" alt="無錫質(zhì)量V法鑄造設(shè)備,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637292187267587891/127050.png"></div><p> V法具有與傳統(tǒng)砂型鑄造無法比擬的優(yōu)勢(shì)，其具體表現(xiàn)在以下七個(gè)方面： </p> <p> 造型易起模，模具少無磨損，金屬模具壽命長(zhǎng)，模具可用木質(zhì)材料； </p> <p> 鑄件尺寸精度高，輪廓清晰，鑄鐵件粗糙度值達(dá)Ra18—25μm。叉車鑄鐵配重是V法鑄造產(chǎn)品的典型**。安徽合力叉車集團(tuán)合肥鑄鍛廠生產(chǎn)的叉車配重，曾獲2002年第四屆北京國(guó)際鑄造工業(yè)展覽會(huì)鑄件一等獎(jiǎng)。世界上叉車和其他工程車所需配重和平衡塊幾乎都是V法鑄造生產(chǎn)的；(3) V法干砂保溫效果和真空抽吸作用都能提高金屬液的流動(dòng)性。試驗(yàn)表明：V法鑄造和濕型鑄造相比，金屬液流動(dòng)性可提高27％。因此V法鑄造不*能生產(chǎn)厚壁鑄件，也能生產(chǎn)薄壁鑄件。如南京東陶（TOTO）有限公司引進(jìn)日本新東鑄造生產(chǎn)線，生產(chǎn)***鑄鐵浴缸，比較大浴缸尺寸為1829mm×1067mm×650mm，鑄件重達(dá)180kg，壁厚7mm，如圖2所示。圖3 天津英昌鋼琴鑄件有限公司生產(chǎn)的鋼琴鑄鐵弦架也是V法鑄造薄壁件的典型產(chǎn)品。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**砂強(qiáng)度。無錫質(zhì)量V法鑄造優(yōu)點(diǎn)</p><p
