Kodi chitsulo cha ductile ndi chiyani?

Ductile iron ndi mtundu wachitsulo champhamvu kwambiri chomwe chinapangidwa m'zaka za m'ma 1950, ntchito yake yonse ili pafupi ndi chitsulo, imachokera ku ntchito yake yabwino kwambiri, yakhala ikugwiritsidwa ntchito bwino kuponya mphamvu zovuta, mphamvu, kulimba, kuvala zofunika zigawo zapamwamba. Chitsulo chachitsulo chasanduka chitsulo chachitsulo chachiwiri pambuyo pa chitsulo chotuwira ndipo chimagwiritsidwa ntchito kwambiri. Zomwe zimatchedwa "chitsulo m'malo mwachitsulo" makamaka zimatanthawuza chitsulo cha ductile.

Nodular cast iron imapezedwa ndi spheroidization ndi chithandizo cha inoculation, yomwe imathandizira bwino mawotchi achitsulo, makamaka ductility ndi kulimba, kuti apeze mphamvu zapamwamba kuposa chitsulo cha carbon.

Zikomo posankha zinthu zathu. Tikuyembekezera kukutumikirani ndi luso lathu.

Ductile kuponyedwa chitsulo sewero chivundikiro ndi mtundu wa mankhwala ductile chitsulo, ductile kuponyedwa chitsulo ndi spherization ndi kuswana processing analandira mpira graphite, mogwira bwino mawotchi mphamvu ya chitsulo chotayidwa, makamaka kusintha plasticity ndi kulimba, motero kupeza mphamvu kuti ndi apamwamba kuposa mpweya. zitsulo. Ductile cast iron inali yapamwamba kwambiri yoponyera chitsulo yomwe idawonetsedwa mu 20^th century, which is close to steel, which is based on its excellent performance and has been successfully used to create some parts that are complex, strong, resilient and wear-resistant, Ductile cast iron has been rapidly developed second only to grey cast iron and is widely used in cast iron materials. It is called”iron generation steel”, mainly ductile iron, Ductile cast iron is divided into circular and square, in urban road management, generally adopt round manhole cover, because round manhole cover is not easy to tilt, can be better protect the safety of pedestrians and vehicles, using the circle manhole cover is mainly considered that the round manhole cover same diameter, when the hole is rolled up, it will be slightly wider than the hole in the bottom and the lid will not fall into the well.

And if you use the square manhole cover, because the diagonal is significantly longer than each of the edges, it’s easy to fall into the well along the diagonal direction of the well and cause safety risks.

Kumidzi ndi chingwe Wells, lalikulu nthawi zambiri amagwiritsidwa ntchito, zomwe zingalepheretse bwino kulowa kwa zakumwa monga mvula.
