Umupira w'icyuma ukoze mu cyuma ukoreshwa mu gusya ufite uburebure bwa mm 20 kugeza 150

Umupira w'icyuma wa Junda, ushingiye ku bikoresho bigezweho n'ikoranabuhanga mu gukora, umupira wacu w'icyuma wakozwe ufite ibyiza byo gukomera cyane, kudapfa kwangirika neza, kudacika intege, kwangirika gusanzwe n'ibindi. Umupira w'icyuma wakozwe ahanini ukoreshwa mu birombe bitandukanye, inganda za sima, ibigo by'amashanyarazi, inganda z'ibinyabutabire n'izindi nganda. Kugira ngo umupira wo gusya urusheho gukora neza, twashyizeho uburyo bwiza bwo gupima ubuziranenge, ibikoresho bigezweho byo kugenzura ubuziranenge no gupima. Twabonye kandi icyemezo mpuzamahanga cya ISO 9001:2008 cy'ubuziranenge. Twiringiye ubufatanye bwanyu.

Junda ikigo gitanga umusaruroφ Kuva kuri 20 kugezaφ Imipira 150 y'icyuma ikoze mu byuma, duhitamo icyuma cy'umweru cyiza, aloyi idafite karuboni nyinshi, icyuma cya manganese nyinshi, karuboni nyinshi n'icyuma cya manganese nyinshi nk'ibikoresho fatizo.bikorwa hakoreshejwe uburyo bwo gucura inyundo mu kirere.Duhitamo icyuma cy’uruziga cy’ubuziranenge nk’ibikoresho fatizo, kandi tugakoresha ibikoresho bigezweho, uburyo bwihariye bwo gutunganya ubushyuhe n’uburyo buhamye bwo kugenzura ubuziranenge kugira ngo tumenye neza ko imipira y’icyuma icuzwe mu bukonje rusange ikora neza. Ubukonje bw’ubuso bugera kuri 58-65HRC, ubukonje bw’ingano bugera kuri 56-64HRC.Uburyo ubukana bukwirakwira buringaniye, agaciro k'ubukana bw'ingaruka ni 12J/cm², kandi igipimo cyo gusya kiri munsi cyane ya 1%. Imiterere y'imipira y'icyuma ikoze mu byuma: ingano ya karuboni is0.4-0.85, ingano ya manganese is0.5-1.2, ingano ya chromium is 0.05-1.2,Dushobora gukora ingano zitandukanye bitewe n'umukiriya'icyifuzo.Twabonye kandi icyemezo mpuzamahanga cya ISO 9001:2008 cy’ubuziranenge bw’isi.
