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(zhì)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(qiáng)：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(jìn)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，南通優(yōu)良V法鑄造設(shè)備廠，南通優(yōu)良V法鑄造設(shè)備廠，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，南通優(yōu)良V法鑄造設(shè)備廠。 </p> <p> （2）噴漆厚度：0.04mm。 </p> <p> （3）使用要求：噴涂均勻，個(gè)別地方要補(bǔ)刷涂料；噴涂后要等待涂料烘干再放砂。固定式冷卻沸騰床采用水循環(huán)冷卻，水泵將冷水輸送至沸騰床內(nèi)冷卻水管中與熱砂充分地?zé)峤粨Q達(dá)到冷卻目的。南通優(yōu)良V法鑄造設(shè)備廠</p><div style="width:100%;text-align: center;"><img

對(duì)于澆注系統(tǒng)的設(shè)計(jì)，不少文獻(xiàn)和資料均有詳盡解說(shuō)，在此不再贅述，*就注意事項(xiàng)簡(jiǎn)要說(shuō)明。 </p> <p> 澆注系統(tǒng)盡量采用半開(kāi)半閉方案，這種扼流型澆注系統(tǒng)可以有效避免高紊流狀態(tài)發(fā)生，可以降低金屬液在充型腔過(guò)程中的流動(dòng)速度和對(duì)型壁、坭芯的沖擊，減少鑄造缺點(diǎn)。 </p> <p> 盡量采用陶瓷材料成型澆注系統(tǒng)，避免鋼水長(zhǎng)時(shí)間沖刷澆道而造成由于夾砂、夾涂料產(chǎn)生的鑄造缺點(diǎn)。 </p> <p> 盡可能采用中間澆注方式，這樣可以減少因底注造成對(duì)上型壁長(zhǎng)時(shí)間烘烤造成塌型、上型凹陷、薄膜和涂料產(chǎn)生的氣孔等，亦可減弱頂注產(chǎn)生對(duì)下型壁和坭芯的沖擊、紊流和裹氣等缺點(diǎn)。 </p> <p> 合理布置冒口，尤其是明冒口布置，一般應(yīng)布置在澆口附近和遠(yuǎn)離澆口的鑄件末端，便于透氣和排氣，易于鑄件成型和減少氣孔。無(wú)錫真空V法鑄造設(shè)備鑄型都必須保持一定的真空度以固定松散的干砂，確保鑄型有足夠的強(qiáng)度和剛度澆注時(shí)防止鑄型坍塌和鑄件變形。</p><div style="width:100%;text-align:

</p> <p> 根據(jù)國(guó)內(nèi)外經(jīng)驗(yàn)來(lái)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(lái)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。 </p><p style="text-indent:25px">V法造型過(guò)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*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(guò)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(guò)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(wèn)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(wèn)題往往模棱兩可，缺乏基本的核算依據(jù)。澆注過(guò)程還必須保護(hù)密封塑料薄膜不被燒掉，否則，將降低鑄型的負(fù)壓度及強(qiáng)度。</p><div

V法鑄造鑄件表面質(zhì)量好，光潔度高；產(chǎn)品尺寸精度高，尤其是中大型鑄件批量化生產(chǎn)條件下的尺寸穩(wěn)定性更具優(yōu)勢(shì)；產(chǎn)品輪廓清晰，可實(shí)現(xiàn)少無(wú)拔模斜度；鋼水流動(dòng)性好，可實(shí)現(xiàn)低溫度澆注，作為提高鑄件晶粒度等級(jí)，提高耐磨性的潛在手段之一； </p> <p> 2生產(chǎn)管理方面 </p> <p> V法鑄造工藝的成本更低，單位鑄件重量能耗和輔材消耗低，勞動(dòng)強(qiáng)度低；采用干砂造型無(wú)需混砂等過(guò)程，設(shè)備投資少，砂處理簡(jiǎn)單，舊砂回用率較高，不存在廢砂廢水等污染情況；模具磨損小，壽命高；高自動(dòng)化程度生產(chǎn)線生產(chǎn)效率高，人均產(chǎn)量高；除塵濾氣罐的主要作用是防止細(xì)砂和粉塵進(jìn)入泵內(nèi)，磨損機(jī)械零件，影響泵的正常工作。無(wú)錫真空V法鑄造設(shè)備</p><p
