球墨鑄鐵件常見缺點(diǎn)的分析與對(duì)策球鐵是近40年來我國發(fā)展起來的重要鑄造金屬材料。由于球狀石墨造成的應(yīng)力集中小，對(duì)基體的割裂作用也較小，故球鐵的抗拉強(qiáng)度，塑性和韌性均高于其他鑄鐵。與相應(yīng)組織的鋼相比，塑性低于鋼，疲勞強(qiáng)度接近一般中碳鋼，屈強(qiáng)比可達(dá)07～08，幾乎是一般碳鋼的2倍，而成本比鋼低，因此其應(yīng)用日趨***。當(dāng)然，球鐵也不是十全十美的，它除了會(huì)產(chǎn)生一般的鑄造缺點(diǎn)外，還會(huì)產(chǎn)生一些特有的缺點(diǎn)，如縮松、夾渣、皮下氣孔、球化不良及衰退等。這些缺點(diǎn)影響鑄件性能，使鑄件廢品率增高。為了防止這些缺點(diǎn)的發(fā)生，有必要對(duì)其進(jìn)行分析，總結(jié)出各種影響因素，提出防止措施，才能有效降低缺點(diǎn)的產(chǎn)生，提高鑄件的力學(xué)性能及生產(chǎn)效益。本文將討論球鐵件的主要常見缺點(diǎn):縮孔、縮松、夾渣、皮下氣孔、石墨漂浮、球化不良及球化衰退。1縮孔縮松(1)碳當(dāng)量：提高碳量，增大了石墨化膨脹，可減少縮孔縮松。此外，提高碳當(dāng)量還可提高球鐵的流動(dòng)性，有利于補(bǔ)縮。生產(chǎn)質(zhì)量鑄件的經(jīng)驗(yàn)公式為Ｃ%+1/7Ｓｉ%>39%。但提高碳當(dāng)量時(shí)，不應(yīng)使鑄件產(chǎn)生石墨漂浮等其他缺點(diǎn)。(2)磷：鐵液中含磷量偏高，使凝固范圍擴(kuò)大，同時(shí)低熔點(diǎn)磷共晶在***凝固時(shí)得不到補(bǔ)給，以及使鑄件外殼變?nèi)?。沙依巴克區(qū)球墨鑄鐵管推薦廠家阿克蘇球墨鑄鐵搶修節(jié)銷售廠家。</p><div
