Icyuma gishyushye gishyushye gifite urubaho rw'icyuma gishyushye gifite uburebure bwa karuboni

Icyuma kizengurutse kivuga icyuma kirekire gikomeye gifite igice cy’uruziga. Ibisobanuro byacyo bigaragazwa mu bugari, muri milimetero (mm). Urugero, "50mm" bivuga icyuma kizengurutse gifite umurambararo wa milimetero 50. Gushyira mu byiciro imiterere y’ibinyabutabire Icyuma cya karuboni gishobora kugabanywamo icyuma gito cya karuboni, icyuma giciriritse cya karuboni n’icyuma kinini cya karuboni hakurikijwe imiterere y’ibinyabutabire (urugero: ingano ya karuboni).

1. Icyuma gito cya karuboni

Nanone izwi nka “fat metal”, “low carbone steel” ifite ingano ya karuboni kuva kuri 0.10% kugeza kuri 0.30%, biroroshye kwakira uburyo butandukanye bwo gutunganya, nko gushushanya, gusudira no gukata. Ikunze gukoreshwa mu gukora iminyururu, amariveti, bolts, imigozi, nibindi.

2. Icyuma kiri hagati cya karuboni

Icyuma cya karuboni gifite ingano ya karuboni 0.25% ~ 0.60%. Hariho icyuma cyishwe, icyuma cyaciwe igice, icyuma gishyuha n'ibindi bicuruzwa. Uretse karuboni, ishobora kandi kuba irimo ingano nto ya manganese (0.70% ~ 1.20%). Dukurikije ubwiza bw'igicuruzwa, igabanyijemo icyuma gisanzwe cy’imiterere ya karuboni n'icyuma cy’imiterere ya karuboni cyiza. Ikorana neza mu gushyuha no gukata, imikorere mibi yo gusudira. Ingufu n'ubukana biri hejuru y'iby'icyuma gito cya karuboni, mu gihe ubuziranenge n'ubukonje biri hasi ugereranyije n'iby'icyuma gito cya karuboni. Ibikoresho bishyushye bizinze kandi bikonje bishobora gukoreshwa mu buryo butaziguye nta bushyuhe bukoreshwa, kandi bishobora no gukoreshwa nyuma yo gushyushya. Icyuma giciriritse cya karuboni ni cyo gikoreshwa cyane mu bikorwa bitandukanye bifite imbaraga ziciriritse. Uretse gukoreshwa nk'ibikoresho by'ubwubatsi, kinakoreshwa cyane mu gukora ibice bitandukanye bya mekanike.

3. Icyuma cya karuboni nyinshi

Akenshi yitwa icyuma cy'ibikoresho, gifite ingano ya karuboni iri hagati ya 0.60% na 1.70%, gishobora gukomera no koroshywa. Inyundo n'icyuma cyo gukata bikozwe mu cyuma gifite ingano ya karuboni iri hagati ya 0.75%; ibikoresho byo gukata nka drill bit, tap na reamer bikozwe mu cyuma gifite ingano ya karuboni iri hagati ya 0.90% na 1.00%.
