去除舊砂中的鐵性雜物一般采用貫通式或懸掛式永磁分選機(jī)。去除舊砂中的薄膜及砂芯等殘?jiān)?，一般選用慣性直線振動(dòng)篩和復(fù)合式篩分機(jī)。熱砂冷卻一般選用固定式流化床砂溫調(diào)節(jié)裝置或冷卻滾筒。除塵系統(tǒng)一般采用集中除塵，將落砂、篩分、冷卻、機(jī)運(yùn)等揚(yáng)塵點(diǎn)集中處理，無(wú)錫質(zhì)量V法鑄造效果，選用旋風(fēng)除塵器與袋式除塵組合式，均能達(dá)到良好的除塵效果，無(wú)錫質(zhì)量V法鑄造效果。

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(jiǎn)易性，對(duì)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(duì)等性。圖9、圖10為某廠生產(chǎn)某種型號(hào)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(duì)于同一套真空系統(tǒng)來(lái)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)。南通真空V法鑄造介紹對(duì)于V法鑄造企業(yè)，結(jié)合企業(yè)生產(chǎn)和產(chǎn)品特點(diǎn)、V法鑄造特性及其主輔材料的功用。</p><div

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(wú)化學(xué)添加劑，作業(yè)環(huán)境優(yōu)化，無(wú)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(wú)拔模斜度。</p><p style="text-indent:25px">而鑄型不可能是完全密封的，始終處在一種氣體泄入并被抽走的過程中。顯然，距離抽氣口越近，氣體被抽速度越快，那么從氣流角度分析，越靠近砂箱四壁和抽氣管的地方，真空保持的越穩(wěn)定，強(qiáng)度也越高。澆注之前，外界氣體泄入量往往較小，會(huì)被及時(shí)抽走，不會(huì)對(duì)鑄型強(qiáng)度造成不利影響。但是，澆注過程中，隨著大面積薄膜的燒蝕，外界氣體泄入量劇增，如果泄入的氣體不能被及時(shí)抽走，鑄型內(nèi)部氣壓上升強(qiáng)度降低，就會(huì)造成塌箱。有時(shí)候盡管砂箱已經(jīng)有四壁抽氣甚至還有少量抽氣箱帶或者抽氣管，而且真空度還很高，仍然會(huì)塌箱。目前國(guó)內(nèi)有十多個(gè)在建的鑄造工業(yè)園區(qū)，均采用高爐—感應(yīng)爐供應(yīng)鐵液，年產(chǎn)鑄件達(dá)100多萬(wàn)噸。</p><div

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。 </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(wú)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
