O le a le mea o le u'amea ductile?

O le uʻamea uʻamea o se ituaiga o mea uʻamea uʻamea malosi maualuga na atiina ae i le 1950, o lona faʻatinoga atoatoa e latalata i le uamea, e faʻavae i luga o lona faʻatinoga sili ona lelei, ua faʻaaogaina lelei e lafo ai ni faʻalavelave faʻalavelave, malosi, faigata, faʻaogaina manaʻoga tetee o vaega maualuga. Ua vave ona atina'e le u'amea ma'ale'ale e avea ma mea fa'amea u'amea lona lua i le u'amea efuefu ma fa'aaoga lautele. O le mea e taʻua o le "uʻamea nai lo le uamea" e masani lava ona faʻatatau i le uʻamea ductile.

Nodular uʻamea uʻamea e maua i le spheroidization ma inoculation togafitiga, lea e faʻaleleia lelei ai mea faʻainisinia o le uʻamea lafo, aemaise lava le ductility ma le faigata, ina ia maua ai le malosi maualuga atu nai lo le sila carbon.

Faafetai mo le filifilia oa matou oloa. Matou te tulimatai atu e auauna atu ia te oe i le mea sili matou te mafaia.

uʻamea lafo uʻamea uʻamea ufiufi o se ituaiga o oloa uʻamea ductile, uʻamea lafo uʻamea e spherization ma le gaosia o le gaosiga maua polo graphite, faaleleia lelei le engergy masini o lafo uʻamea, aemaise lava le faaleleia o le plasticity ma le faigata, o lea e maua ai le malosi e maualuga atu nai lo carbon. uamea. O le u'amea fa'ameamea e maualuga le maualuga o le u'amea na fa'aalia i le 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 totonu o nuʻu ma cable Wells, e masani ona faʻaogaina sikuea, e mafai ona sili atu ona puipuia le ulufale mai o vai e pei o timuga.
