Agakoresho k'icyuma gakozwe mu cyuma gikozwe mu cyuma | Inkoni y'icyuma ikoreshwa mu cyuma cya SG
Intangiriro y'ibicuruzwa
Icupa ry'icyuma rikozwe mu buryo bwa High Strength Ductile Iron Bar ni ibikoresho byo mu rwego rwo hejuru byakorewe mu buryo bwihariye ibice bya mekanike bisaba gukomera no gukora neza. Bizwi kandi nka SG Iron cyangwa Spheroidal Graphite Iron, iki gikoresho gihuza ubushobozi bwo gucukura icyuma n'imiterere ya mekanike yegereye icyuma. Kubera imbaraga zacyo zidasanzwe, ubushobozi bwo gukora neza, n'ubushobozi bwo kudakoresha imitingito, icupa ry'icyuma rikozwe mu buryo bwa ductile ryabaye amahitamo meza mu bikorwa bitandukanye by'inganda, harimo sisitemu za hydraulic, ibice by'imashini, n'ibice byo kohereza ingufu.
Bitandukanye n'icyuma cy'umukara, icyuma gikozwe mu buryo bwa ductile gifite graphite mu ishusho y'uruziga, ibyo byongera imbaraga zayo zo gukurura no kurwanya impanuka. Iyi nyungu y'imiterere mito ituma iramba cyane mu bihe bikomeye, bigatuma ikwirakwira haba mu mitwaro idahinduka cyangwa ihindagurika. Uduti tw'icyuma dukozwe mu buryo bwa ductile turaboneka mu mpande zitandukanye kandi dushobora gutangwa mu bihe bikomeye cyangwa byakozwe mu buryo bunoze kugira ngo bihuze n'ibikenewe mu nganda zitandukanye.
- Uduti tw'icyuma dukozwe hakurikijwe amahame mpuzamahanga. Ingano z'icyuma gikoreshwa cyane mu duti tw'icyuma dukozwe mu buryo butandukanye hakurikijwe ibihugu n'amahame atandukanye.
Ibi bikurikira ni ibipimo by'icyuma gikoreshwa mu byuma bikozwe mu buryo bwa ductile (amanota) muri sisitemu nyinshi zisanzwe:
| ASTM A536 | MU 1563 | ISO 1083 | JIS G5502 |
| 60-40-18 | EN-GJS-400-15 | GGG40 | FCD400 |

Ibisobanuro by'igicuruzwa
Uduce tw’icyuma duto ni ibikoresho binoza imiterere yabyo binyuze mu kongeramo ibintu bihindura imiterere nka manyeziyumu cyangwa cerium kugira ngo icyuma gikore graphite mu buryo bw’uruziga. Ku bijyanye n’imiterere ya shimi, ibice by’ingenzi bya feri ihindura imiterere ni icyuma, karuboni, silicon, hamwe na manganese, fosifore, sulfur n’ibindi bintu. Kongeramo ibintu bihindura imiterere nka manyeziyumu cyangwa cerium ni ingenzi, bitera imbere kurema imiterere y’uruziga muri graphite.
Inkoni z'icyuma zikoreshwa mu buryo bwa "ductile iron rods" zikunze gukoreshwa mu bice nka za "veteri" n'ibice by'umugozi mu nganda zikora imashini, "crankshafts" n'ibice bihuza imodoka, imiyoboro n'ibice by'imiterere mu bwubatsi, ibice by'amazi mu mashini z'ubwubatsi, na "valve" n'ibice by'imashini zitanga ingufu.
