style="text-indent:25px">由于球墨鑄鐵管具有鐵的性質(zhì)和鋼的性能，所以稱為球墨鑄鐵管。球墨鑄鐵管廠家中石墨呈球形適用，石墨粒徑為6-7。在質(zhì)量方面，建議鑄鐵管球化等級(jí)掌控在1-3級(jí)，球化率≥80%。因此，材料本身的力學(xué)性能獲得了提升，具備鐵的性質(zhì)和鋼的性能。球墨鑄鐵管燒結(jié)之后的金相組織為鐵素體和少量珠光體。它具備不錯(cuò)的力學(xué)性能，所以又稱鑄鐵管。1947年，H.morrough找到在過共晶灰鑄鐵中退出鈰后，當(dāng)其含量小于0.02wt%時(shí)，石墨呈球形。1948年，A.P.ganganebin等人。美國(guó)的研究人員聲稱，在鑄鐵之中退出鎂，再退出硅鐵，當(dāng)鎂的殘留量小于0.04wt%時(shí)，可獲得球形石墨。此后，球墨鑄鐵起大規(guī)模工業(yè)化生產(chǎn)。鑄鐵管的使用歷史可上溯到1668年，當(dāng)時(shí)從塞納河到凡爾賽宮的輸油管道在巴黎郊區(qū)約為21.14公里。300年之后，除了部分管道和插頭的維修和替換之外，主體仍在采用。北海DN500球墨鑄鐵管價(jià)格表廣西貴港球墨鑄鐵管k9。</p><div
