影响铸铁井盖质量问题的因素有哪些?

来源:http://www.kpp647.com添加时间:2017-02-05 17:54:45

铸铁井盖主要是被应用在城市下水道中,但造成其质量问题的因素在哪些?

The main cast iron manhole cover is being applied in the sewers of the city, but the cause of quality problems in what factors?

因为南北环境的差异,南方的铸铁井盖普遍要比北方的重量偏低,但千万不要认为越重越好。

Because the environmental differences between the north and the south, the South than the common cast iron covers North low weight, but do not think that the more the better。

质量好的铸铁井盖是要看其韧度和硬度的。一般来讲的话,硬度越高,质量越好。但需要注意一点就是硬度跟上了,其韧性也要跟上,这样才能算是好的铸铁井盖。

Cast iron manhole cover of good quality is to see its toughness and hardness. Generally speaking, the higher the hardness, the better the quality. But need to note is a hardness up, its toughness is to catch up, this can be a good iron manhole cover.

硬度和韧性这是材质上的问题,另外对于铸铁井盖质量的问题还在于设计上,这是因为铸铁井盖使用的尺寸,形状等都是必须从铸造合金和铸造工艺特性角度来考虑其设计的合理性。

The hardness and toughness of this material is the problem, in addition to the quality of the cast iron manhole cover problem lies in the design, this is because the use of cast iron manhole cover size, shape is necessary from the perspective of casting alloy and casting process characteristics to consider the rationality of the design。

主要是明显的尺寸效应和凝固、收缩、应力等问题,避免或减少铸铁井盖的成分偏析、变形、开裂等缺陷的产生。最后就是对于铸造工艺要合理。

Is mainly the size effect and solidification, shrinkage, stress and other issues clearly, to avoid or reduce the segregation, iron manhole cover deformation and crack defects。 Finally, the casting process to be reasonable。
