鑄鐵井蓋分為球墨鑄鐵井蓋和灰鑄鐵井蓋，一般來(lái)說(shuō)，同等重量的球墨鑄鐵井蓋要比灰鐵井蓋抗壓能力強(qiáng)?；诣F井蓋采用的材料一般為HT200,球墨井蓋采用材料一般為QT500-7球墨鑄鐵井蓋主要由球墨鑄鐵打造出來(lái)的井蓋，這種井蓋質(zhì)量的好壞就牽扯到了球化率的問(wèn)題。處理鑄件的常用涂料就是防銹瀝青漆了，當(dāng)然球墨鑄鐵井蓋的表面也是經(jīng)過(guò)噴涂防銹瀝青漆處理的。球墨鑄鐵井蓋有一個(gè)優(yōu)點(diǎn)，就是由于球墨鑄鐵強(qiáng)度高、韌性好，使得球墨鑄鐵井蓋要比同類型的灰口鑄鐵井蓋輕30%左右。 </p> <p> 球墨鑄鐵的強(qiáng)度和鑄鋼的強(qiáng)度是可比的。球墨鑄鐵具有更高的屈服強(qiáng)度，其屈服強(qiáng)度至少為40k，而鑄鋼的屈服強(qiáng)度只有36k。在大部分市政應(yīng)用領(lǐng)域，如：水、鹽水、蒸汽等，球墨鑄鐵的耐腐蝕性和抗氧化性都超過(guò)鑄鋼。應(yīng)用領(lǐng)域，市政道路，高速公路，通信，電力，自來(lái)水，小區(qū)，學(xué)校等各種園區(qū)。

在球墨鑄鐵管及球墨鑄鐵井蓋選材時(shí)的注意事項(xiàng)及方法。首先球墨鑄鐵井蓋是用來(lái)井口防護(hù)用。而且它的使用環(huán)境也非常惡劣，必須具很高的耐腐蝕性，很強(qiáng)的抗壓性能。同時(shí)球墨鑄鐵管必須具備很高的**老性能，一般球墨鑄鐵井蓋出現(xiàn)的問(wèn)題是破裂，破裂是因?yàn)殍T造中熱處理時(shí)溫度過(guò)高，或者是在鑄造中沒(méi)有適當(dāng)?shù)募右恍┓乐惯^(guò)硬改變適當(dāng)?shù)拇嘈栽斐善屏训挠行С煞帧Ｔ诖私ㄗh你采用鑄鐵修補(bǔ)機(jī)，目前市場(chǎng)有賣，但也只能是補(bǔ)焊保證其外觀完好無(wú)損，讓你的產(chǎn)品通過(guò)質(zhì)量關(guān)，但是如果是在使用性能上不能夠滿足效果，特別是井蓋承受的壓力相當(dāng)大的話，那么用什么方法都是沒(méi)有用，必須要重新鑄造了做新的了。
