Chii chinonzi ductile iron?

Ductile iron imhando yemhando yepamusoro yesimbi yakakandwa simbi yakagadzirwa muma1950s, kuita kwayo kwakazara kuri padyo nesimbi, yakavakirwa pakuita kwayo kwakanaka, yakashandiswa zvakabudirira kukanda mamwe masimba akaomarara, simba, kuoma, kupfeka zvinodiwa zvikamu zvakakwirira. Ductile iron yakakurumidza kugadzirwa kuita simbi yakakandwa yechipiri chete kune grey iron uye inoshandiswa zvakanyanya. Iyo inonzi "iron pachinzvimbo chesimbi" inonyanya kureva ductile iron.

Nodular cast iron inowanikwa ne spheroidization uye inoculation kurapwa, iyo inobudirira inovandudza michina yesimbi yakakandwa, kunyanya iyo ductility uye kuoma, kuitira kuti uwane yakakwirira simba kupfuura kabhoni simbi.

Tinokutendai nekusarudza zvigadzirwa zvedu. Tinotarisira kukushandirai nepamusoro pezvatinokwanisa.

Ductile cast iron sewer cover imhando ye ductile iron chigadzirwa, ductile cast iron by spherization uye kuberekesa kugadziridzwa kwakawanikwa bhora graphite, zvinobudirira kuvandudza mechaniki emagetsi esimbi yakakandwa, kunyanya kuvandudza plastiki uye kuoma, nekudaro kuwana simba iro rakakwirira kupfuura kabhoni. simbi. Ductile cast iron yaive yakakwira degree iron casting material yakaratidzwa mu20^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.

Mumaruwa netambo Wells, sikweya inowanzoshandiswa, iyo inogona kudzivirira zvirinani kupinda kwezvinwiwa zvakaita semvura.
