Iyini impahla ye-ductile iron?

I-Ductile iron iwuhlobo lwensimbi enamandla kakhulu eyakhiwe ngeminyaka yawo-1950s, ukusebenza kwayo okuphelele kuseduze nensimbi, kusekelwe ekusebenzeni kwayo okuhle kakhulu, isetshenziswe ngempumelelo ukuphonsa amandla athile ayinkimbinkimbi, amandla, ukuqina, izidingo zokumelana nokugqoka. izingxenye eziphakeme. I-Ductile iron ithuthuke ngokushesha yaba insimbi eyinsimbi yesibili ngemva kwensimbi empunga futhi isetshenziswa kabanzi. Okubizwa ngokuthi "insimbi esikhundleni sensimbi" ngokuyinhloko kubhekisela ku-ductile iron.

I-nodular cast iron itholakala nge-spheroidization kanye nokwelashwa kwe-inoculation, okuthuthukisa ngokuphumelelayo izakhiwo zemishini yensimbi ekhonjiwe, ikakhulukazi i-ductility kanye nokuqina, ukuze uthole amandla aphezulu kune-carbon steel.

Siyabonga ngokukhetha imikhiqizo yethu. Sibheke phambili ekukhonzeni ngamakhono ethu angcono kakhulu.

Isembozo se-ductile cast iron sewer siwuhlobo lomkhiqizo we-ductile iron, i-ductile cast iron by spherization kanye nokuzalanisa ukucutshungulwa okutholwe i-ball graphite, kuthuthukisa ngempumelelo amandla emishini yensimbi ekhonjiwe, ikakhulukazi ukuthuthukisa ipulasitiki nokuqina, ngaleyo ndlela uthole amandla aphezulu kunekhabhoni. insimbi. I-Ductile cast iron yayiyi-high degree casting material eyavezwa ku-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.

Ezindaweni zasemaphandleni kanye nekhebula Wells, isikwele ngokuvamile sisetshenziswa, esingavimbela kangcono ukungena koketshezi olufana nemvula.
