He aha te mea o te rino ngongo?

Ko te rino ductile he ahua o nga rauemi rino kaha teitei i whakawhanakehia i nga tau 1950, ko tana mahi matawhānui e tata ana ki te maitai, i runga i tana mahi tino pai, kua pai te whakamahi ki te maka i etahi ope uaua, te kaha, te uaua, te kakahu i nga whakaritenga aukati o nga waahanga teitei. Ko te rino ngongo kua tere te tipu hei taonga rino whakarewa tuarua ki te rino hina, ka whakamahia nuitia. Ko te mea e kiia nei ko te "rino hei utu mo te rino" e pa ana ki te rino ductile.

Ka whiwhi te rino nodular ma te spheroidization me te maimoatanga inoculation, he pai ake te whakapai ake i nga ahuatanga miihini o te rino maka, ina koa te ngawari me te uaua, kia kaha ake ai te kaha o te waro.

Mauruuru koe mo te whiriwhiri i a maatau hua. Kei te tumanako matou ki te mahi ki a koe me o maatau kaha.

Ko te hipoki rino rino rino he ahua o te hua rino ngongo, te rino ductile na roto i te spherization me te tukatuka whakatipu i whiwhi graphite poroporo, ka pai ake te whakapai ake i te miihini o te rino maka, ina koa te whakapai ake i te kirihou me te uaua, na reira ka whiwhi i te kaha teitei ake i te waro. maitai. Ko te rino whakarewa he taonga whakarewa rino teitei i whakaatuhia i te 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.

I nga tuawhenua me nga Puna taura, ka whakamahia te tapawha, he pai ake te aukati i te urunga o nga wai penei i te ua.
