球墨鑄鐵管是鑄鐵的一種，是一種鐵、碳和硅的合金。球墨鑄鐵中石墨是以球狀形式存在的，一般石墨的大小為6-7級，質(zhì)量上要求鑄管的球化等級控制為1-3級（球化率≥80%），因而材料本身的機械性能得到了較好的改善，具有鐵的本質(zhì)，鋼的性能。 </p> <p> <br /> </p><p style="text-indent:25px">1948年美國A. P.Ganganebin等人研究指出，在鑄鐵中添加鎂，隨后用硅鐵孕育，當殘余鎂量大于0.04wt%時，得到球狀石墨。從此以后，球墨鑄鐵開始了大規(guī)模工業(yè)生產(chǎn)。有關鑄鐵管的使用歷史可以追溯到1668年巴黎郊區(qū)從塞納河至凡爾賽全場約21.14Km的輸水管線，300年的時光流逝，除部分管道和接頭維修更換外，主體仍在使用中。我國球墨鑄鐵管的現(xiàn)狀及前景我國球墨鑄鐵管的行業(yè)起步于20世紀90年代初，在中國城鎮(zhèn)供水協(xié)的大力支持下發(fā)展迅猛，經(jīng)過近30年的實踐使用，其安全性、實用性已被供水行業(yè)普遍認可，2008年國內(nèi)年產(chǎn)量已達到220萬噸，是1990年的11倍。由于我國是一個水資源缺乏的國家，缺水城市為600多個，嚴重缺水城市為200多個，供水節(jié)水事業(yè)方興未艾，球墨鑄鐵管有著廣闊的發(fā)展前景。球墨鑄鐵管廠家

球墨鑄鐵管的機械性能比焊接鋼管還好，可承受較高的壓力，便于鋪設、檢查、維修，同時球墨鑄鐵管的抗腐蝕性能優(yōu)于焊接鋼管，埋設使用壽命是鋼管的二倍以上?？梢姙楸ＷC水管的質(zhì)量勢必要用稀土球墨鑄鐵管。 </p> <p> 球墨鑄鐵管就是在成型前的原料鐵水中加入稀土及其它元素，使鐵水得到凈化，同時使鐵水石墨化，提高鑄鐵管的抗壓強度，硬度，塑性和延伸率，增強了抗壓力和抗沖擊性，保證鑄鐵管的質(zhì)量，使之能適應較為惡劣的環(huán)境下使用，且有幾倍于一般灰口鑄鐵管的使用壽命。 </p> <p> <br /> 北臺球墨鑄鐵管，廣西國鑄實業(yè)。桂林球墨管安裝</p><p
