He aha ka mea o ka hao ductile?

ʻO ka hao Ductile kahi ʻano mea hao ikaika kiʻekiʻe i hoʻomohala ʻia i ka makahiki 1950, ua kokoke kāna hana piha i ke kila, ua hoʻokumu ʻia ma kāna hana maikaʻi loa, ua hoʻohana maikaʻi ʻia e hoʻolei i kekahi mau ikaika paʻakikī, ikaika, paʻakikī, ʻaʻahu i nā koi kūpaʻa o ʻāpana kiʻekiʻe. Ua ulu koke ka hao ductile i mea hao hao lua wale nō i ka hao hina a hoʻohana nui ʻia. ʻO ka mea i kapa ʻia "hao ma kahi o ke kila" e pili ana i ka hao ductile.

Loaʻa ka hao nodular e ka spheroidization a me ka mālama ʻana i ka inoculation, e hoʻomaikaʻi maikaʻi ana i nā waiwai mechanical o ka hao hao, ʻoi aku ka ductility a me ka paʻakikī, i loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona.

Mahalo iā ʻoe no ke koho ʻana i kā mākou huahana. Manaʻo mākou e lawelawe iā ʻoe me ka maikaʻi o kā mākou hiki.

ʻO Ductile cast iron sewer cover he ʻano huahana ductile hao, ductile cast iron e ka spherization a me ka hoʻoulu ʻana i ka hana i loaʻa i ka graphite pōpō, hoʻomaikaʻi maikaʻi i ka engergy mechanical o ka hao hao, ʻoi aku ka hoʻomaikaʻi ʻana i ka plasticity a me ka paʻakikī, no laila e loaʻa ai ka ikaika i ʻoi aku ka kiʻekiʻe ma mua o ke kalapona. kila. ʻO ka hao hoʻoheheʻe Ductile kahi mea hoʻoheheʻe hao kiʻekiʻe i hōʻike ʻia ma ka 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.

Ma ke kua'āina a me nā Uila uwea, hoʻohana maʻamau ka square, hiki ke pale i ke komo ʻana o nā wai e like me ka ua.
