我國鑄造企業(yè)數(shù)量多，整體鑄件質量較低，鑄造企業(yè)所面臨的環(huán)保壓力、人力成本壓力越來越大，從提升產品質量控制環(huán)境污染的角度，V法鑄造工藝有望在今后引起更好的關注和更***的應用。3

<p> 將帶有過濾抽氣管的砂箱，放在已覆有薄膜的模板上。 </p> <p> 充填、振實、刮平箱內干砂，放上密封膜，抽負壓，使鑄型內外產生壓力差而緊實，。 </p> <p> 解除模樣內真空，起模。鑄型保持負壓狀態(tài)，直到下芯，合箱，澆鑄。 </p> <p> 脫箱落砂。冷卻后，將砂箱內的壓力恢復到常壓狀態(tài)，砂型自動潰散，鑄件保溫后取出，砂冷卻后返回系統(tǒng)循環(huán)使用，將鑄件取走進入清理工部完成工藝過程。南通負壓V法鑄造廠分析砂溫對砂處理設備設計和鑄件質量控制的影響，從而科學和適宜地進行砂溫控制。</p><div style="width:100%;text-align: center;"><img

關于V法鑄造工藝優(yōu)勢的討論國外典型耐磨鑄件生產企業(yè)實踐證明V法鑄造工藝在耐磨鑄件的生產上是成功的，也是有優(yōu)勢的。具體優(yōu)勢如下： </p> <p> 1產品質量方面 </p> <p> V法鑄造鑄件表面質量好，光潔度高；產品尺寸精度高，尤其是中大型鑄件批量化生產條件下的尺寸穩(wěn)定性更具優(yōu)勢；產品輪廓清晰，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，勞動強度低；采用干砂造型無需混砂等過程，設備投資少，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；高自動化程度生產線生產效率高，人均產量高； </p><p> 20世紀7o年代末我國有十余家企業(yè)引進了日本和德國V法鑄造設備和技術，提升了我國V法鑄造水平。據粗略統(tǒng)計，國內現(xiàn)有v法鑄造企業(yè)近200家，主要分布在山西、江蘇、安徽、山東和河北等地。江陰華天科技開發(fā)有限公司為青島四海電力鑄造廠設計一種固定式簡易V法造型機，它是鋼結構焊接而成，由底座支撐架、震實臺、負壓箱、頂箱機構等組成，具有結構新穎、外形美觀、運行可靠的特點。震實臺由四組頂桿同步，將砂箱平穩(wěn)地與模型分離。頂箱機的控制設有就地電控箱，人工操作，便于掌握起模時間。這種V法造型機機構簡單，更換模板方便，人工操作與機械化造型相結合，投資少，上馬快，比較適合單件、小批量鑄造車間使用，生產中、小型V法鑄件。面有所突破。 </p> <p> <br /> 根據涂料不同骨料組配的特性，合理地選擇V法鑄造用型砂。</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,V法鑄造" src="https://tyunfile.71360.com/UploadFile/Jyhuatian/637293889462666016/4862105.png"></div><p> V法具有與傳統(tǒng)砂型鑄造無法比擬的優(yōu)勢，其具體表現(xiàn)在以下七個方面： </p> <p> 造型易起模，模具少無磨損，金屬模具壽命長，模具可用木質材料； </p> <p> 鑄件尺寸精度高，輪廓清晰，鑄鐵件粗糙度值達Ra18—25μm。叉車鑄鐵配重是V法鑄造產品的典型**。安徽合力叉車集團合肥鑄鍛廠生產的叉車配重，曾獲2002年第四屆北京國際鑄造工業(yè)展覽會鑄件一等獎。世界上叉車和其他工程車所需配重和平衡塊幾乎都是V法鑄造生產的；(3) V法干砂保溫效果和真空抽吸作用都能提高金屬液的流動性。試驗表明：V法鑄造和濕型鑄造相比，金屬液流動性可提高27％。因此V法鑄造不僅能生產厚壁鑄件，也能生產薄壁鑄件。如南京東陶（TOTO）有限公司引進日本新東鑄造生產線，生產***鑄鐵浴缸，比較大浴缸尺寸為1829mm×1067mm×650mm，鑄件重達180kg，壁厚7mm，如圖2所示。圖3 天津英昌鋼琴鑄件有限公司生產的鋼琴鑄鐵弦架也是V法鑄造薄壁件的典型產品。縮短了生產鏈，省去了高爐鐵水凝固和重熔環(huán)節(jié)，簡稱為短流程鑄造工藝。南通負壓V法鑄造廠</p><p style="text-indent:25px">金屬液平穩(wěn)充型，避免沖刷鑄型或產生飛濺，一般采用底注半封閉式或開放式澆注系統(tǒng)。無錫真空密封V法鑄造</p><p style="text-indent:25px">可借鑒的參考數(shù)據是，振幅0.5mm左右，頻率不低于1500/min可以達到比較好的震實效果。不太理想的是，部分震實臺的設計參數(shù)并不滿足推薦的經驗數(shù)據。而鑄造企業(yè)在使用的過程中則常常發(fā)現(xiàn)，震實臺激振力不夠或過強，振幅不足或過大等一系列問題。這就是為什么同樣的鑄件，同樣的砂箱，同樣的模具，在不同的廠家，震實時間，震實效果有差異的原因。更有甚者，震實臺振動電機缺乏基本的變頻功能；哪怕具備變頻特性，也不根據震實臺負載的變化合理調整頻率，激振力等參數(shù)，以至于震實臺發(fā)揮不了應有的作用。無錫真空密封V法鑄造</p><p
