塑性和韧性是球墨铸铁井盖特有的特点

来源:http://www.kpp647.com添加时间:2017-10-24 17:25:29

  山东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。

  Ductile iron manhole cover is generally divided into round and square, in the urban road, generally round, because the round well cover is not easy to tilt, can better protect the safety of pedestrians and vehicles。

  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。

  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。

  球墨铸铁井盖是球墨铸铁产品的一种,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。

  Ductile iron manhole cover is a kind of nodular cast iron, 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.

  新型球墨铸铁井盖的化学及物理特点采用qt500-7铸态球墨铸铁,重量轻、强度高、韧性好、防腐蚀、耐疲劳、成本适宜,与同规格尺寸灰铸铁井盖相比,重量轻40%~50%,强度比旧式的灰铸铁井盖相比高40%~50%。旧式灰铸铁井盖脆性大,容易断裂。

  The physical and chemical characteristics of new type ductile iron manhole cover using QT500-7 nodular cast iron, light weight, high strength, good toughness, corrosion resistance, fatigue resistance, proper cost, compared with the same size of gray cast iron manhole cover, light weight 40%~50%, intensity ratio of gray cast iron covers the old phase ratio of 40%~50%。 The old cast iron manhole covers are brittle and easy to break。

  井盖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。

  The cover 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。
