塑性和韧性是铸铁井盖的优势

  球磨铸铁井盖的主要成分还是球墨铸铁通过球化和孕育处理得到球状石墨,有效地提高了铸铁的机械性能,特别是提高了塑性和韧性,从而得到比碳钢还高的强度。

  The main component of milling cast iron covers or nodular cast iron by spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel.

  球磨铸铁井盖的发展经历了几十年的发展,其综合性能接近于钢,正是基于其优异的性能,已成功地用于铸造一些受力复杂,强度、韧性、耐磨性要求较高的零件。

  The development of nodular cast iron manhole cover after decades of development, its comprehensive performance is close to the steel, it is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts.

  球墨铸铁井盖一般分为圆形和方形,在市区的路政方面,一般采用圆形,因为 圆形的井盖不易倾斜,能够较好的保护好行人和车辆的安全。使用圆形,主要是考虑到圆形的井盖通过其圆心的每条直径长度都是一样的,这样如果井盖被经过的车辆轧起时,因为不论如何轧起,其直径都会比下面的井口略宽,井盖不会掉到井口里去。

  Ductile iron covers are generally round and square, in the urban areas of highways, generally used round, because the circular manhole cover is not easy to tilt, can better protect the safety of pedestrians and vehicles。 Use the circular, mainly taking into account the circular covers through its center of each diameter length is the same, so if the covers were passing vehicles rolled up, because no matter how rolling, the diameter will be slightly wider than the wellhead, will not fall to the wellhead to manhole cover。

  而如果采用方形,因为方形的对角线明显长于其每条边长,这样的井盖被轧起时,很容易沿井口的对角线方向掉进井中,造成安全隐患。如果井口做成圆形或明显小于井盖,方形的井盖就不会掉进井中。

  And if the square is used, because the square diagonal is obviously longer than each of its side length, such a manhole cover is rolled up, it is easy to fall into the well along the diagonal line of the wellhead, resulting in security risks。 If the wellhead is circular or smaller than the manhole cover, the square manhole cover will not fall into the well。

  这里就牵涉到一个材料的更大利用和节约的问题。井口的使用取决于井口的大小,如果非要在上面安装个面积远远大于井口的方形井盖,那么材料的利用和实用价值自然没有直接使用圆形的井盖更有效,既节约井盖的材料,也保证了井口的安全

  Here is the question of the maximum use and savings of a material. The wellhead is used depends on the size of the wellhead, if to a non square manhole cover installed in the above area is far greater than the wellhead, then the material utilization and practical value of nature is not directly using the circular covers more effective, saving material covers also ensures the safety of the wellhead.
