關(guān)于V法鑄造工藝優(yōu)勢(shì)的討論國(guó)外典型耐磨鑄件生產(chǎn)企業(yè)實(shí)踐證明V法鑄造工藝在耐磨鑄件的生產(chǎn)上是成功的，也是有優(yōu)勢(shì)的。具體優(yōu)勢(shì)如下： </p> <p> 1產(chǎn)品質(zhì)量方面 </p> <p> 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)需混砂等過程，南京密封V法鑄造原理，設(shè)備投資少，砂處理簡(jiǎn)單，南京密封V法鑄造原理，南京密封V法鑄造原理，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；降低咯鑄型的透氣性，較粗的型砂，可提高鑄型的透氣性。南京密封V法鑄造原理</p><div
