為解決降低鐵液中的含硫量，減少硫化物的產(chǎn)生，應(yīng)控制W(S)<0.02%;適當(dāng)提高澆鑄溫度，有利于夾渣上浮;球化劑中稀土含量不易過高，稀土含量控制在1-2%為宜;加強鐵液的扒渣和擋渣效果;鐵液中的殘鎂流量不易過高(控制在0.035-0.045%)，以減少鐵液表面氧化。 </p> <p> 通過采取以上相應(yīng)措施，球墨鑄鐵管的質(zhì)量得到明顯改善，裂紋、重皮、夾渣缺陷大為降低，減少了廢品，大幅提高綜合成材率。二、安裝應(yīng)注意的幾個問題 </p> <p> 1．膠圈應(yīng)在承口槽內(nèi)放正，并用手壓實。 </p> <p> <br />

球墨鑄鐵管的抗拉強度是灰口鑄鐵管的三倍；球墨鑄鐵管水壓試驗是灰口鑄鐵管的二倍；球墨鑄鐵管有較高的延伸率，而灰口鑄鐵管為脆性材料，其延伸率為0。 </p> <p> 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(shè)、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(shè)使用壽命是鋼管的二倍以上。可見為保證水管的質(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(yīng)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 /> 廣西離心球墨鑄鐵管生產(chǎn)廠家

球墨鑄鐵管是一種鑄鐵，是鐵、碳、硅的合金。球墨鑄鐵中的石墨以球體的形式存在。石墨粒徑一般為6-7級，鑄管質(zhì)量要求為1-3級（球化率≥80%）。因此，隨著鐵的性質(zhì)和鋼的性質(zhì)，材料本身的機械性能得到了提高。退火球墨鑄鐵管的金相組織為鐵素體和少量珠光體。球墨鑄鐵管主要稱為離心球墨鑄鐵管。它具有鐵的性質(zhì)，鋼的性能，優(yōu)良的耐腐蝕性，良好的延展性，良好的密封效果，安裝簡單，主要用于市政、工礦企業(yè)的供水、輸氣、輸油等，是性價比高的供水管道的優(yōu)先。與聚乙烯管相比，球墨管的安裝時間比聚乙烯管簡單、快捷，安裝后內(nèi)外承壓較好；在氣密性和耐腐蝕性方面，球墨管安裝后氣密性較好，耐腐蝕性較好也可以通過多種防腐手段加以改進；從水力性能來看，球墨管的規(guī)格一般是指內(nèi)徑，而聚乙烯管的規(guī)格一般是指外徑，因為在同一規(guī)格下，球形墨管可以實現(xiàn)更大的徑流量，從綜合安裝維護成本來看，球形墨管具有更優(yōu)越的性價比。內(nèi)壁噴鋅、水泥砂漿防腐材料等
