一、球墨鑄鐵的概念球墨鑄鐵是通過球化和孕育處理得到的球狀石墨，有效地提高了鑄鐵的機(jī)械性能，特別是提高了塑性和韌性，從而得到比碳鋼還高的強(qiáng)度。球墨鑄鐵是20世紀(jì)五十年代發(fā)展起來的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)異的性能，已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性、耐磨性要求較高的零件。球墨鑄鐵已迅速發(fā)展為僅次于灰鑄鐵的、應(yīng)用十分***的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。二、成分生鐵是含碳量大于2％的鐵碳合金，工業(yè)生鐵含碳量一般在，并含C、SI、Mn、S、P等元素，是用鐵礦石經(jīng)高爐冶煉的產(chǎn)品。根據(jù)生鐵里碳存在形態(tài)的不同，又可分為---煉鋼生鐵、鑄造生鐵和球墨鑄鐵等幾種。析出的石墨呈球形的鑄鐵。球狀石墨對(duì)金屬基體的割裂作用比片狀石墨小，使鑄鐵的強(qiáng)度達(dá)到基體組織強(qiáng)度的70～90％，抗拉強(qiáng)度可達(dá)120kgf/mm2，并且具有良好的韌性。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量～％，含硅量～％，含錳、磷、硫總量不超過％和適量的稀土、鎂等球化劑。三、性能球鐵鑄件差不多已在所有主要工業(yè)部門中得到應(yīng)用，這些部門要求高的強(qiáng)度、塑性、韌性、耐磨性、耐嚴(yán)重的熱和機(jī)械沖擊、耐高溫或低溫、耐腐蝕以及尺寸穩(wěn)定性等。新市區(qū)球墨鑄鐵管廠家電話阿克蘇給水球墨鑄鐵管哪家好。</p><div

</p><p> 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(guó)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)?。阿克蘇球墨鑄鐵搶修節(jié)生產(chǎn)廠家。</p><div

使得球墨鑄鐵具有更加良好的展延性和抗沖擊性，而鑄鐵內(nèi)部的薄片形式導(dǎo)致鑄鐵沒有展延性。通過鐵素體基體可獲得較佳的展延性。因此，球墨鑄鐵的壓力負(fù)載部件都經(jīng)過鐵素體化退火周期的工藝處理后，球墨鑄鐵內(nèi)部的球狀結(jié)構(gòu)也能夠消除鑄鐵內(nèi)部的薄片石墨容易產(chǎn)生的裂縫現(xiàn)象。在球墨鑄鐵的微觀照片中，可以看見裂縫***到石墨球后終止。在球墨鑄鐵行業(yè)內(nèi)，這些石墨球稱為“裂縫終結(jié)者”，因?yàn)樗鼈兙哂凶柚箶嗔训哪芰Α１疚南嚓P(guān)詞條解釋球墨鑄鐵球墨鑄鐵鑄鐵是含碳量大于，由工業(yè)生鐵、廢鋼等鋼鐵及其合金材料經(jīng)過高溫熔融和鑄造成型而得到，除Fe外，還含C、Si、Mn、S、P等五大元素及其它合金元素。鑄鐵中的碳以石墨形態(tài)析出，若析出的石墨呈條片狀時(shí)的鑄鐵叫灰口鑄鐵或灰鑄鐵、呈蠕蟲狀時(shí)的鑄鐵叫蠕墨鑄鐵、呈團(tuán)絮狀時(shí)的鑄鐵叫白口鑄鐵或碼鐵、而呈球狀時(shí)的鑄鐵就叫球墨鑄鐵。球狀石墨對(duì)金屬基體的割裂作用比其它形狀石墨小，能使鑄鐵的強(qiáng)度達(dá)到基體組織強(qiáng)度的70～90%，抗拉強(qiáng)度可達(dá)120kgf/mm2，并且具有良好的韌性。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量～，含硅量～。阿克蘇球墨鑄鐵水篦子要多少錢。頭屯河區(qū)球墨鑄鐵管銷售廠家</p><p

降低殘留鎂量(<007%)；采用稀土鎂合金來處理，稀土氧化物殘余量控制在002%～004%。(2)工藝設(shè)計(jì)要確保鑄件在凝固中能從冒口不斷地補(bǔ)充高溫金屬液，冒口的尺寸和數(shù)量要適當(dāng)，力求做到順序凝固。(3)必要時(shí)采用冷鐵與補(bǔ)貼來改變鑄件的溫度分布，以利于順序凝固。(4)澆注溫度應(yīng)在1300～1350℃，一包鐵液的澆注時(shí)間不應(yīng)超過25ｍｉｎ，以免產(chǎn)生球化衰退。(5)提高砂型的緊實(shí)度，一般不低于90；撞砂均勻，含水率不宜過高，保證鑄型有足夠的剛度。2夾渣(1)硅：硅的氧化物也是夾渣的主要組成部分，因此盡可能降低含硅量。(2)硫：鐵液中的硫化物是球鐵件形成夾渣缺點(diǎn)的主要原因之一。硫化物的熔點(diǎn)比鐵液熔點(diǎn)低，在鐵液凝固過程中，硫化物將從鐵液中析出，增大了鐵液的粘度，使鐵液中的熔渣或金屬氧化物等不易上浮。因而鐵液中硫含量太高時(shí)，鑄件易產(chǎn)生夾渣。球墨鑄鐵原鐵液含硫量應(yīng)控制在006%以下，當(dāng)它在009%～0135%時(shí)，鑄鐵夾渣缺點(diǎn)會(huì)急劇增加。(3)稀土和鎂：近年來研究認(rèn)為夾渣主要是由于鎂、稀土等元素氧化而致，因此殘余鎂和稀土不應(yīng)太高。(4)澆注溫度：澆注溫度太低時(shí)，金屬液內(nèi)的金屬氧化物等因金屬液的粘度太高，不易上浮至表面而殘留在金屬液內(nèi)；溫度太高時(shí)。頭屯河區(qū)球墨鑄鐵管銷售廠家</p><p
