一、前言曲軸是汽車發(fā)動(dòng)機(jī)的關(guān)鍵部件之一，其性能好壞直接影響汽車的壽命。曲軸工作時(shí)承受著大負(fù)荷和不斷變化的彎矩及扭矩作用，常見的失效形式為彎曲疲勞斷裂及軸頸磨損，因此要求曲軸材質(zhì)具有較高的剛性和疲勞強(qiáng)度以及良好的耐磨性能。隨著球墨鑄鐵技術(shù)的發(fā)展，其性能也在不斷提高，質(zhì)量廉價(jià)的球鐵已成為制造曲軸的重要材料之一。自1947年球墨鑄鐵發(fā)明以來，經(jīng)過不長時(shí)間的努力，其抗拉強(qiáng)度提高到了600~900MPa，接近或超過了碳素鋼的水平。與鍛鋼材料比較，球墨鑄鐵曲軸既有制造簡便、成本低廉，又有吸震、耐磨、對表面裂紋不敏感等鍛鋼材料所不具備的優(yōu)良特性，因而球墨鑄鐵具備了代替鍛鋼制造曲軸的可能性。20世紀(jì)50年代后期，國內(nèi)南京汽車制造廠率先批量生產(chǎn)躍進(jìn)牌汽車球鐵曲軸。60年代，二汽首先成為國內(nèi)按照球鐵曲軸生產(chǎn)工藝進(jìn)行設(shè)計(jì)和投產(chǎn)的汽車廠。到了70、80年代，中小型柴油機(jī)在我國迅速發(fā)展，由于球鐵制造和經(jīng)濟(jì)方面的優(yōu)勢，大多數(shù)中小型柴油機(jī)都采用球鐵曲軸，極大地推動(dòng)了我國球鐵曲軸的應(yīng)用與發(fā)展，出現(xiàn)了一批球鐵曲軸專業(yè)生產(chǎn)廠。近十多年在汽車工業(yè)的快速發(fā)展過程中，又新建了一批現(xiàn)代化的球鐵曲軸生產(chǎn)廠（或分廠、車間），球鐵曲軸在國內(nèi)得到了普遍應(yīng)用。阿克蘇離心球墨鑄鐵管便宜。</p><div

必要時(shí)添加微量銻、鉍等可防止球墨鑄鐵件中心部位的石墨畸變和組織疏松。c球墨鑄鐵管道：墨鑄鐵管，具有與鋼管相同的優(yōu)良機(jī)械性能（特別是高韌性）、良好的耐腐蝕性能、長久的使用壽命、安裝簡便快捷、維修費(fèi)用低廉、輸送過程中無污染無泄漏、且有抗震，抗沉降能力，尤其是能夠提高城市中抵御災(zāi)害的水平，以保證居民的生命與財(cái)產(chǎn)安全。一舉在城市地下輸水、輸氣管網(wǎng)的建設(shè)中得到迅速的推廣和***應(yīng)用。六、制造步驟（一）嚴(yán)格要求化學(xué)成分，對原鐵液要求的碳硅含量比灰鑄鐵高，降低球墨鑄鐵中錳，磷，硫的含量（二）鐵液出爐溫度比灰鑄鐵更高，以補(bǔ)償球化，孕育處理時(shí)鐵液溫度的損失（三）進(jìn)行球化處理，即往鐵液中添加球化劑（四）加入孕育劑進(jìn)行孕育處理（五）球墨鑄鐵流動(dòng)性較差，收縮較大，因此需要較高的澆注溫度及較大的澆注系統(tǒng)尺寸，合理應(yīng)用冒口，冷鐵，采用順序凝固原則（六）進(jìn)行熱處理七、發(fā)展前途球墨鑄鐵的噸位增加和市場滲透是很驚人的，這種材料的市場潛力是巨大的。由于“節(jié)能”的要求，導(dǎo)致很多領(lǐng)域基本上都要重新設(shè)計(jì)零件，以達(dá)到重量輕、效率高是我要求，這就必然要提醒設(shè)計(jì)者們集中注意材料，而球墨鐵管就成了比較好的選擇。水磨溝區(qū)球墨鑄鐵管廠家推薦</p><p
