干燥良好的無缺點(diǎn)木材是V法鑄造常用模具材料。金屬材料價(jià)格昂貴，而且鉆孔較困難，并不太適合用于V法模具。另外暴露于薄膜加熱器下的金屬模具受重復(fù)加熱作用，溫度上升后易粘薄膜。因此V法鑄造企業(yè)長期采用木質(zhì)材料制模，而其大多是靠模型工放樣半機(jī)械化制作。其尺寸精度較差和生產(chǎn)周期較長一直是V法鑄造的瓶頸。無錫覆膜砂V法鑄造優(yōu)點(diǎn)干砂造型抽真空后減小了砂與砂之間的間隙，增加了砂與砂之間的摩擦力，提高砂強(qiáng)度。</p><div

style="text-indent:25px">V法鑄造是真空密封造型或負(fù)壓造型鑄造工藝的簡稱，其原理是利用塑料薄膜覆模造型并密封砂箱，依靠真空泵抽出型內(nèi)空氣，造成型內(nèi)箱外壓力差，使干砂緊實(shí)，形成所需型腔。其比較大優(yōu)勢(shì)是型砂不使用粘結(jié)劑，干砂回用率高達(dá)95%以上，不僅節(jié)能環(huán)保、落砂簡便、改善勞動(dòng)條件，而且鑄件表面品質(zhì)和尺寸精度**提高。V法鑄造是日本長野縣工業(yè)試驗(yàn)所和秋田株式會(huì)社于1971年的發(fā)明專利。V法鑄造至今經(jīng)過了38年的發(fā)展，同消失模鑄造一樣，作為第3代造型方法即物理硬化方法，在世界上尤其是在中國獲得了長足的發(fā)展。</p><p style="text-indent:25px">V法工藝生產(chǎn)耐磨鑄件的發(fā)展V法鑄造1973年起源于日本，80年代引入中國后得到了***關(guān)注，并逐步應(yīng)用于很多產(chǎn)品的生產(chǎn)。同時(shí)，該工藝傳入北美及歐洲地區(qū)，取得了長足發(fā)展，應(yīng)用范圍不斷擴(kuò)展，在叉車配重、工程機(jī)械橋殼、浴盆等領(lǐng)域獲得了非常成熟的應(yīng)用。在耐磨鑄件領(lǐng)域，V法鑄造工藝在瑞典山特維克、美國耐磨狼、美伊電鋼等**耐磨鑄件生產(chǎn)企業(yè)的使用中獲得了極大成功，并逐步成為這些企業(yè)的主流工藝。在國內(nèi)，從上世紀(jì)80年代開始有初步探索該工藝生產(chǎn)耐磨鑄件的試驗(yàn)，但是沒有成熟應(yīng)用（除鐵路道岔外）。近些年，在耐磨鑄件生產(chǎn)領(lǐng)域，V法鑄造工藝重新得到重視和關(guān)注。目前，V法鑄造在耐磨鑄件的生產(chǎn)應(yīng)用方面主要以傳統(tǒng)礦山耐磨鑄件為主，包括高錳鋼圓錐、齒板、錘頭、板錘、大型襯板等。甚至有些企業(yè)成功將立磨所用高鉻輥套鑄件采用V法鑄造工藝生產(chǎn)，取得了不錯(cuò)的效果。鑄造的鑄件上箱型腔表面積大時(shí)，應(yīng)將鑄型傾斜澆注，使金屬液從型腔低端進(jìn)入；</p><div

國內(nèi)年消耗量超過200 萬t , 目前已有近千家耐磨鑄件生產(chǎn)企業(yè), 年生產(chǎn)能力達(dá)到500 萬噸以上，鑄造工藝多種多樣。 </p> <p> 耐磨鑄件工藝現(xiàn)狀 </p> <p> 目前，耐磨鑄件普遍采用水玻璃砂，堿酚醛樹脂砂鑄造工藝，也有部分采用消失模鑄造工藝。這些工藝靈活穩(wěn)定，工藝成熟度較相對(duì)較高，能夠?qū)崿F(xiàn)穩(wěn)定批量化生產(chǎn)，是耐磨鑄件生產(chǎn)的傳統(tǒng)工藝。但尤其是水玻璃砂、樹脂砂工藝同時(shí)存在著勞動(dòng)強(qiáng)度大，人均生產(chǎn)效率低的弊端，在環(huán)保問題日益嚴(yán)峻、勞動(dòng)力成本越來越高的***，傳統(tǒng)工藝面臨著較大的壓力。 </p> <p> 結(jié)合產(chǎn)業(yè)升級(jí)的趨勢(shì)，國內(nèi)部分企業(yè)探索V法鑄造工藝生產(chǎn)耐磨鑄件，產(chǎn)品類型以軋臼壁、破碎壁、齒板、錘頭等中大型鑄件為主，所生產(chǎn)的鑄件具有表面質(zhì)量好，尺寸精度高的優(yōu)勢(shì)，同時(shí)造型落砂等工序勞動(dòng)強(qiáng)度低，具有相對(duì)比較好的環(huán)保優(yōu)勢(shì)。為增加干砂的堆積密度，采用高頻率低振幅的振動(dòng)方式使砂箱中干砂緊實(shí)。泰州先進(jìn)V法鑄造優(yōu)點(diǎn)</p><p style="text-indent:25px">為了穩(wěn)定系統(tǒng)壓力，避免澆注時(shí)出現(xiàn)塌箱，應(yīng)加大穩(wěn)壓罐容積。南京優(yōu)良V法鑄造裝備</p><p> 重視原輔材料的使用 </p> <p> 原輔材料對(duì)于鑄件質(zhì)量有直接的影響，重視原輔材料的使用，理解原輔材料對(duì)工藝過程及產(chǎn)品質(zhì)量的影響，對(duì)于提升鑄件質(zhì)量具有重要意義。V法鑄造工藝特別強(qiáng)調(diào)薄膜和涂料的使用控制，而耐磨鑄件本身對(duì)冒口補(bǔ)縮要求相對(duì)也較高，因此EVA薄膜，涂料，冒口等材料的使用技術(shù)在V法鑄造耐磨件方面比較關(guān)鍵。尤其是涂料的噴涂控制和烘干技術(shù)，冒口的安放及發(fā)氣量控制，不僅影響鑄件質(zhì)量，同時(shí)關(guān)系著生產(chǎn)作業(yè)效率和生產(chǎn)組織安排。另外，陶瓷管等其他輔助材料也將對(duì)鑄件沖砂和澆注安全性有著重要的影響。
