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

style="text-indent:25px">美國(guó)耐磨狼公司，作為北美地區(qū)礦山耐磨行業(yè)耐磨鑄件的主要供應(yīng)商，采用V法鑄造生產(chǎn)線生產(chǎn)耐磨鑄件，獲得了優(yōu)異的產(chǎn)品質(zhì)量，并將V法鑄造工藝發(fā)展成為了耐磨件鑄造的主流工藝。該公司從1979年開始接觸V法鑄造工藝，共有三條V法鑄造生產(chǎn)線，產(chǎn)品重量在225kg-4500kg之間，單條生產(chǎn)線生產(chǎn)效率比較高達(dá)15箱/小時(shí)。該公司同時(shí)擁有自硬砂鑄造工藝，針對(duì)不同要求產(chǎn)品進(jìn)行不同工藝的搭配生產(chǎn)，其中V法鑄造生產(chǎn)了超過75%的鑄件。該公司認(rèn)為V法鑄造主要有如下優(yōu)勢(shì)：鑄件的一致性好，客戶對(duì)鑄件尤其是大型鑄件一致性的要求更高；環(huán)境友好，生產(chǎn)過程無化學(xué)添加劑，作業(yè)環(huán)境優(yōu)化，無需混砂；更好的鑄件質(zhì)量，鑄件尺寸精度非常出色，鑄件表面質(zhì)量更好；無拔模斜度。當(dāng)負(fù)壓度小于0.038MPa時(shí)，鑄型易發(fā)生脹箱、變形及塌砂。</p><div

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。再生的舊砂成套設(shè)備應(yīng)包括落砂，輸送、分選、過篩及砂冷卻系統(tǒng)。揚(yáng)州優(yōu)良V法鑄造工藝</p><p

style="text-indent:25px">V法造型過程中，震動(dòng)是獲得高緊實(shí)度砂型的重要環(huán)節(jié)。V法鑄型的硬度和強(qiáng)度，不僅與我們常規(guī)理解中的砂箱的真空度有關(guān)系，震實(shí)效果也是很重要的一方面（如圖4所示）。在震實(shí)不夠的情況下，有時(shí)候通過高的真空度，可以獲得較高的鑄型硬度，但這只是一種假象，砂型強(qiáng)度往往是不足的。在砂型抽真空，翻轉(zhuǎn)，轉(zhuǎn)運(yùn)，合箱，澆注等過程中產(chǎn)生的波動(dòng)又會(huì)造成鑄型內(nèi)砂子形位的重新排布進(jìn)而引起鑄型強(qiáng)度，結(jié)構(gòu)尺寸等的變化。而這些變化反映到鑄件上，則表現(xiàn)出鑄件尺寸或者重量精度超差等質(zhì)量問題。目前在震實(shí)臺(tái)設(shè)計(jì)中，對(duì)于振幅，震動(dòng)頻率，激振力及如何配置振動(dòng)電機(jī)等問題往往模棱兩可，缺乏基本的核算依據(jù)。南京密封V法鑄造裝備</p><p
