P.Ganganebin等人研究指出，在鑄鐵中添加鎂，隨后用硅鐵孕育，當(dāng)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(guān)球墨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(jì)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20年的實踐使用，其性、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，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。在中低壓管網(wǎng)（一般用于6MPa以下），球墨鑄鐵管具有運行可靠，破損率低，施工維修方便、快捷，防腐性能優(yōu)異等。新開發(fā)的”巖盾“系列管道可以適用于非開挖施工，廣泛應(yīng)用在過河、穿路、穿越建筑的管線施工中?！辟愪\“系列管道則使用特殊鋅鋁合金外噴涂工藝，數(shù)倍提高管道的耐腐蝕性能，廣泛用于腐蝕性較強的土壤施工中。缺點一般不使用在高壓管網(wǎng)（6MPa以上）。由于管體相對笨重，安裝時必須動用機械。打壓測試后出現(xiàn)漏水，必須把所有管道全部挖出，把管道吊起至能放進卡箍的高度，安裝上卡箍阻止漏水。山東華夏聯(lián)豐鑄造有限公司高經(jīng)理訂購熱線136-9865-2159</div><p><img
