style="text-indent:25px">美國耐磨狼公司，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，無錫真空密封V法鑄造特點，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15箱/小時。該公司同時擁有自硬砂鑄造工藝，無錫真空密封V法鑄造特點，針對不同要求產(chǎn)品進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。該公司認為V法鑄造主要有如下優(yōu)勢：鑄件的一致性好，無錫真空密封V法鑄造特點，客戶對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。型砂粒度對鑄型負壓度變化的影響很大，較細的型砂有利于防止金屬液滲透。無錫真空密封V法鑄造特點</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="無錫真空密封V法鑄造特點,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889762324219/6573071.png"></div><p style="text-indent:25px">V法鑄造一般選擇用熱塑性簿膜，要求成型性好，易涂（刷）涂料，方向性小，熱塑應(yīng)力小，對熱量不敏感，燃燒時發(fā)氣量小，不產(chǎn)生有害氣體，質(zhì)優(yōu)價廉。筆者采用EVA薄膜作為V法鑄造塑料簿膜。覆膜成型時，簿膜置于加熱器下150～200mm,加熱溫度為80～120℃，加熱時間一般為20～50s。簿膜加熱至鏡面狀時應(yīng)迅速將其落下覆膜，覆膜后，須檢查簿膜是否與模樣表面緊密貼緊，是否有無孔洞或破損。對于某些難以吸膜成型的部位，采取局部強化抽真空措施，調(diào)節(jié)抽氣速度實現(xiàn)覆膜成型。南通負壓V法鑄造優(yōu)點目前國內(nèi)有十多個在建的鑄造工業(yè)園區(qū)，均采用高爐—感應(yīng)爐供應(yīng)鐵液，年產(chǎn)鑄件達100多萬噸。</p><div

src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889370097657/738567.png"></div><p> 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。 </p><p> <p> 砂處理設(shè)備 </p> <p> V法鑄造生產(chǎn)線的砂處理系統(tǒng)主要解決四個問題：一是去除舊砂中存在的鐵屑、鐵渣等雜物；二是去除舊砂斗中薄膜及砂芯的殘渣；三是落砂后的熱砂降溫至所需的溫度范圍；四是整個砂處理系統(tǒng)的除塵和吸塵保證舊砂的再生質(zhì)量和環(huán)保的要求。一般V法所用砂含泥量低于0.3～0.5%之內(nèi)。 </p> <p> 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。去除舊砂中的薄膜及砂芯等殘渣物，一般選用慣性直線振動篩和復(fù)合式篩分機。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、機運等揚塵點集中處理，選用旋風(fēng)除塵器與袋式除塵組合式，均能達到良好的除塵效果。 </p> </p> <p> <br /> 開設(shè)補縮冒口須根據(jù)砂型鑄造工藝原則、V法鑄造工藝特點及鑄件特點等具體確定。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="無錫真空密封V法鑄造特點,V法鑄造"

從國內(nèi)大部分耐磨企業(yè)的生產(chǎn)情況來看，以上優(yōu)勢并沒有完全在生產(chǎn)中發(fā)揮出來，這與我們對V法鑄造工藝的認識欠缺，對基礎(chǔ)研究的投入以及對設(shè)備輔材的配套研究不足有很大關(guān)系。 </p> <p> 4技術(shù)發(fā)展水平方面 </p> <p> V法鑄造在國內(nèi)發(fā)展的時間有限，局限于鑄造設(shè)備企業(yè)的研發(fā)創(chuàng)新能力，V法鑄造生產(chǎn)線形式單一，難以針對特殊鑄件開發(fā)**裝備，這也是V法鑄造在國內(nèi)耐磨件生產(chǎn)方面受到局限的問題之一。目前國內(nèi)多數(shù)生產(chǎn)線仍然采用傳統(tǒng)的布局形式，生產(chǎn)線效率低，控制水平差異導(dǎo)致生產(chǎn)過程不穩(wěn)定，產(chǎn)品質(zhì)量難以達到V法應(yīng)有的質(zhì)量水平，同時行業(yè)內(nèi)又缺乏高水平的先進V法鑄造生產(chǎn)線及相關(guān)裝備企業(yè)。澆注過程還必須保護密封塑料薄膜不被燒掉，否則，將降低鑄型的負壓度及強度。南通覆膜砂V法鑄造裝備</p><p style="text-indent:25px">近國內(nèi)消失模生產(chǎn)廠家發(fā)展迅速，尤其是中小廠家，但實踐中有些鑄件采用消失模鑄造不很對號。無錫真空密封V法鑄造特點</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，強度也越高。澆注之前，外界氣體泄入量往往較小，會被及時抽走，不會對鑄型強度造成不利影響。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抽走，鑄型內(nèi)部氣壓上升強度降低，就會造成塌箱。有時候盡管砂箱已經(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，仍然會塌箱。無錫真空密封V法鑄造特點</p><p
