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，南京優(yōu)良V法鑄造廠，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，南京優(yōu)良V法鑄造廠，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。該公司同時擁有自硬砂鑄造工藝，針對不同要求產(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：鑄件的一致性好，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，南京優(yōu)良V法鑄造廠，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。金屬液平穩(wěn)充型，避免沖刷鑄型或產(chǎn)生飛濺，一般采用底注半封閉式或開放式澆注系統(tǒng)。南京優(yōu)良V法鑄造廠</p><div

耐磨鑄造車間的建設(shè)是一個系統(tǒng)工程，除了生產(chǎn)設(shè)備本身外，車間布局物流設(shè)計，原輔材料的配套，熱處理系統(tǒng)的配套，機(jī)加工設(shè)備的配套等都要作為系統(tǒng)的一部分考慮。 </p> <p> 以砂箱的周轉(zhuǎn)為例，耐磨鑄件由于保溫冷卻時間長，在一定程度上限制了砂箱的流轉(zhuǎn)速度，企業(yè)訂購大量砂箱不***增加了企業(yè)成本，而且造成管理使用上的困難?？赏ㄟ^采用建設(shè)冷卻立體庫，設(shè)計冷卻托盤的方式加快砂箱流轉(zhuǎn)，同時節(jié)約生產(chǎn)場地。標(biāo)準(zhǔn)化托盤的設(shè)計和制作，滿足叉車運輸條件，并不額外增加過多的勞動力，實現(xiàn)了工藝生產(chǎn)的要求，降低了設(shè)備投資成本，同時提高的系統(tǒng)運行效率。南通負(fù)壓V法鑄造生產(chǎn)線生產(chǎn)表明，鑄型內(nèi)負(fù)壓度大于0.044MPa時鑄型就可以保持足夠的強(qiáng)度和穩(wěn)定性。</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；產(chǎn)品輪廓清晰，可實現(xiàn)少無拔模斜度；鋼水流動性好，可實現(xiàn)低溫度澆注，作為提高鑄件晶粒度等級，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，勞動強(qiáng)度低；采用干砂造型無需混砂等過程，設(shè)備投資少，砂處理簡單，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；高自動化程度生產(chǎn)線生產(chǎn)效率高，人均產(chǎn)量高；四工位造型機(jī)的旋轉(zhuǎn)由氣缸驅(qū)動，并有可靠的定位機(jī)構(gòu)，整機(jī)動作采用可編程控制器（即PC）程序控制。</p><div

style="text-indent:25px">V法鑄造用的砂箱，其結(jié)構(gòu)形式直接決定著砂箱內(nèi)負(fù)壓場的形成和分布，也就決定著鑄型強(qiáng)度的大小和均勻性。但是，不少觀念錯誤的認(rèn)為，只要砂箱里面能夠抽氣就行，至于怎么抽，抽多少，都無關(guān)緊要，只要不塌箱即可。所以目前，既有單純的抽氣管抽氣的砂箱，也有靠四壁抽氣的砂箱，**復(fù)雜的則有四壁抽氣并外加箱帶或抽氣管輔助的形式；似乎都達(dá)到了同樣的目的，都能生產(chǎn)出鑄件。然而，產(chǎn)生的影響卻是不一樣的。生產(chǎn)上習(xí)慣了用真空度來衡量或者表征鑄型的強(qiáng)度，認(rèn)為真空度越高，鑄型強(qiáng)度越高，塌箱的幾率也越小；實際上，對于砂箱來說，真空的形成是氣體流動的結(jié)果，是型腔內(nèi)的空氣被真空系統(tǒng)抽走之后形成的。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。南京先進(jìn)V法鑄造流程</p><p
