     球墨铸铁井圈井盖是东升宏运球墨铸铁铸件的一种产品，球墨铸铁通过球化和孕育处理球状石墨，更好地提高了铸铁的机械性能，特别是提高了塑性和韧性，从而比碳钢还高的强度。

     处理铸件的常用涂料就是防锈沥青漆了，当然球墨铸铁井圈井盖的表面也是经过喷涂防锈沥青漆处理的。球墨铸铁井盖有一个优点，就是由于球墨铸铁、韧性好，使得球墨铸井盖要比同类型的灰口铸铁井盖轻30%左右。

     井盖的防震是通过在井圈的止口处设置为U型槽，用T型合成橡胶条，嵌入U型槽中，在井盖与井圈的接触过程中，以起到缓冲作用，减轻振动力。井盖要防响，这就需要井盖与井圈的接触咬合面，直接作用于T型橡胶条上，以柔克刚，消除噪音。
