(10)檢查井施工應(yīng)與鑄鐵管安裝，安裝符合設(shè)計要求和規(guī)章制度后，立即施工排水閉水試驗。 </p> <p> (11)直到他們已經(jīng)通過了閉水試驗的土料回填操作，回填分層回填，為了避免過度搗固力影響管，靠前層虛擬高度不應(yīng)小于1米，并使用低能量輕壓實，在每一層虛擬高度不低于500毫米，較低的能量光壓實。 </p> <p> 球墨鑄鐵管本身也是一種鑄鐵管，因為其球化率的程度，所以材料的機(jī)械性在一定程度上的得到了不錯的改善。球墨管擁有鐵的本質(zhì)，還有鋼的優(yōu)良性能。在退火后，球墨管具有良好的機(jī)械性能和延展性。同時球墨鑄鐵管也具有很好的防腐效果和也很好的密封效果。球墨管的安裝十分的簡單，使用起來十分的方便。 </p><p> 球墨鑄鐵是20世紀(jì)五十年代發(fā)展起來的一種**度鑄鐵材料，其綜合性能接近于鋼，正是基于其優(yōu)異的性能，已成功地用于鑄造一些受力復(fù)雜，強(qiáng)度、韌性、耐磨性要求較高的零件。球墨鑄鐵已迅速發(fā)展為僅次于灰鑄鐵的、應(yīng)用十分大量的鑄鐵材料。所謂“以鐵代鋼”，主要指球墨鑄鐵。 </p> <p> 那么球墨鑄鐵用球化劑和孕育劑有什么作用呢？ </p> <p> 球化劑作用于球墨鑄鐵，可以促進(jìn)石墨結(jié)晶成球狀化，有利于得到球狀石墨，經(jīng)過球化的球墨鑄鐵強(qiáng)度大幅高于灰鑄鐵，韌性優(yōu)于可鍛鑄鐵，有效地提高了球磨鑄鐵的機(jī)械性能，特別是提高了球墨鑄鐵塑性和韌性，從而使鑄鐵得到比碳鋼還高的強(qiáng)度。 </p> <p> 我國稀土資源豐富，普遍使用的球化劑是硅鐵稀土鎂球化劑，國外大都采用鎂系球化劑，如純鎂或鎂合金，少數(shù)國家則采用鈣系球化劑。球墨鑄鐵管廠家 DN800 鑄鐵給水管現(xiàn)貨供應(yīng)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
