球墨鑄鐵、鑄鐵、鑄鋼的區(qū)別？與鑄鐵相比，球墨鑄鐵在強(qiáng)度方面具有的優(yōu)勢(shì)。球墨鑄鐵的抗拉強(qiáng)度是60k，而鑄鐵的抗拉強(qiáng)度只有31k。球墨鑄鐵的屈服強(qiáng)度是40k，而鑄鐵并沒(méi)有顯示出屈服強(qiáng)度，并且較終出現(xiàn)斷裂。球墨鑄鐵的強(qiáng)度-成本比遠(yuǎn)遠(yuǎn)優(yōu)于鑄鐵。球墨鑄鐵的強(qiáng)度和鑄鋼的強(qiáng)度是可比的。球墨鑄鐵具有更高的屈服強(qiáng)度，其屈服強(qiáng)度較低為40k，而鑄鋼的屈服強(qiáng)度只有36k。在大部分市政應(yīng)用領(lǐng)域，如：水、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和抗氧化性都超過(guò)鑄鋼。由于球墨鑄鐵的球狀石墨微觀(guān)結(jié)構(gòu)，在減弱振動(dòng)能力方面，球墨鑄鐵優(yōu)于鑄鋼，因此更加有利于降低應(yīng)力。選擇球墨鑄鐵的一個(gè)重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎，鑄造效率更高，也較少了球墨鑄鐵的機(jī)加工成本。作為鋼的替代品，1949年人類(lèi)開(kāi)發(fā)了球墨鑄鐵。鑄鋼含碳量少于，而鑄鐵和球墨鑄鐵含炭量量則至少為3%。鑄鋼中的低含碳量使得作為游離石墨存在的碳不會(huì)形成結(jié)構(gòu)薄片。鑄鐵內(nèi)的碳天然形式是游離石墨薄片形式。在球墨鑄鐵內(nèi)，這種石墨薄片通過(guò)特殊的處理方法變化成微小的球體。這種改進(jìn)后的球體使得使得球墨鑄鐵比鑄鐵和鋼相比具有更加優(yōu)異的物理性能。正是這種碳的球狀微觀(guān)結(jié)構(gòu)。天山區(qū)球墨鑄鐵管價(jià)格多少阿勒泰離心球墨鑄鐵管廠(chǎng)家直供。</p><div

金屬液表面的熔渣變得太稀薄，不易自液體表面去除，往往隨金屬液流入型內(nèi)。而實(shí)際生產(chǎn)中，澆注溫度太低是引起夾渣的主要原因之一。此外，澆注溫度的選取還應(yīng)考慮碳、硅含量的關(guān)系。(5)澆注系統(tǒng):澆注系統(tǒng)設(shè)計(jì)應(yīng)合理,具有擋渣功能,使金屬液能平穩(wěn)地充填鑄型,力求避免飛濺及紊流。(6)型砂：若型砂表面粘附有多余的砂子或涂料，它們可與金屬液中的氧化物合成熔渣，導(dǎo)致夾渣產(chǎn)生；砂型的緊實(shí)度不均勻，緊實(shí)度低的型壁表面容易被金屬液侵蝕和形成低熔點(diǎn)的化合物，導(dǎo)致鑄件產(chǎn)生夾渣。(1)控制鐵液成分：盡量降低鐵液中的含硫量(<006%)，適量加入稀土合金(01%～02%)以?xún)艋F液，盡可能降低含硅量和殘鎂量。(2)熔煉工藝：要盡量提高金屬液的出爐溫度，適宜的***，以利于非金屬夾雜物的上浮、聚集。扒干凈鐵液表面的渣子，鐵液表面應(yīng)放覆蓋劑(珍珠巖、草木灰等)，防止鐵液氧化。選擇合適的澆注溫度，比較好不低于1350℃。(3)澆注系統(tǒng)要使鐵液流動(dòng)平穩(wěn)，應(yīng)設(shè)有集渣包和擋渣裝置(如濾渣網(wǎng)等)，避免直澆道沖砂。(4)鑄型緊實(shí)度應(yīng)均勻，強(qiáng)度足夠；合箱時(shí)應(yīng)吹凈鑄型中的砂子。3石墨漂浮(1)碳當(dāng)量：碳當(dāng)量過(guò)高，以致鐵液在高溫時(shí)就析出大量石墨。由于石墨的密度比鐵液小。</p><p> 球墨鑄鐵件常見(jiàn)缺點(diǎn)的分析與對(duì)策球鐵是近40年來(lái)我國(guó)發(fā)展起來(lái)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(jiàn)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)優(yōu)質(zhì)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)酢０⒗仗╇x心球墨鑄鐵管哪家好。</p><div
