对比传统灰铸铁井盖球墨井盖的不一样之处

来源:http://www.kpp647.com添加时间:2018-04-03 15:52:34

  从化学成分上和物理性质上来看,球墨铸铁无论是在抗拉性上仍是延伸率上,仍是屈从强度上都是比灰铸铁的要高,极限荷载压头的目标决议了球墨铸铁要高出其他资料的商品。如今有许多的井盖都面临着盗窃的表象,由于球墨铸铁有必定的收回使用的价值。

  In terms of chemical composition and physical properties, nodular cast iron is still higher in tensile and elongation than gray iron。 The target of ultimate load pressure head decides that ductile iron should be higher in other materials。 Nowadays many manholes are faced with the appearance of theft, because ductile iron has a certain value of recovery。

  球墨铸铁井盖与灰铸铁井盖商品有一样的地方,可是它们的原料是不一样的。它的分量比灰铸铁的要轻、强度高、耐性好,并且耐腐蚀性能得到了改进,所以它耐酸、耐碱、耐化学物品。

  Ductile iron covers and gray iron covers are the same, but their raw materials are different. Its weight is lighter than that of gray iron, high strength and good durability, and its corrosion resistance has been improved, so it is acid resistant, alkali resistant and chemical resistant.

  在防盗方面上咱们这种球墨铸铁做了极好的改观。选用的是暗门形式,由固定孔和弹簧轴及推力固定卡衔接,敞开的时分需求专用的提锁插入并进行顺时针旋转九十度,使得锁门退出的时分获取盖板上并不需求提手锁。这样能够完成主动锁紧的状态。更加的简略、结实、可靠、便利。

  In terms of anti-theft, our ductile iron has made an excellent improvement。 It is used in the form of a dark door, which is connected by a fixed hole and a spring shaft and a thrust fixed card。 A special lock is inserted and rotated clockwise for ninety degrees。 This can complete the state of active locking。 More concise, strong, reliable and convenient。

  对比传统的灰铸铁井盖脆性对比大,很简略就会发生开裂的表象。球墨铸铁以及灰铸铁的商品的主要性能做一下对比。球墨铸铁井盖在施工的时分,井盖、雨水篦子都应当和支座外表制造平坦、润滑,不得有裂纹和影响查看井盖运用性能的冷隔、缩松等缺点,不得补焊。

  Comparing with the brittleness contrast of the traditional gray iron manhole cover, the appearance of cracking will happen very simply. The main properties of ductile iron and gray iron are compared. During the construction of the ductile iron shaft cover, the shaft cover and the rainwater grate should be made flat and lubricated with the appearance of the support. There must be no cracks and influence on the cold septum, shrinkage and loosening of the performance of the cover.
