Kanda Iron Machole

Mavhavha emugodhi wesimbi akakamurwa kuita ductile iron manhole mavhavha uye grey iron manhole anovhara, kazhinji kutaura, huremu hwakafanana hwema ductile iron manhole anovhara pane grey iron mugero unovhara kumanikidza kuramba.Izvo zvinoshandiswa ku grey iron manhole chivharo chinowanzo HT200, uye zvinhu zvinoshandiswa kune ductile inki manhole chivharo kazhinji QT500-7.

Hunhu hwe spheroidal inki manhole chivharo:

Kuomarara kwakanaka.Iko kukosha kwekukanganisa kwakafanana neiyo yepakati kabhoni simbi uye inodarika kagumi iyo yegrey iron.

Kuramba kwakasimba kwekuora.Mvura yekupfapfaidza corrosion test, mazuva makumi mapfumbamwe ekuora ingori 1/40 simbi pombi, iri 1/10 grey iron pombi.Hupenyu hwesevhisi ndeye 2 kaviri iyo yegrey iron pombi uye kashanu iyo yeyakajairika simbi pombi.

Plasticity yakanaka.Elongation7%, yakafanana neyepamusoro kabhoni simbi zvinhu, nepo grey iron material elongation iri zero.

Simba repamusoro.Tensile simba ob420MPa, goho simba os300MPa, uye yakaderera kabhoni simbi yakafanana, inopetwa katatu yegrey iron material.

Chishandiso: mugwagwa wekanzuru, mugwagwa mukuru, kutaurirana, simba, pombi mvura, nharaunda, chikoro uye mamwe mapaki.
