Junda yahimbye umupira wibyuma, yishingikirije kubikoresho bigezweho hamwe nubuhanga bwo gukora, umupira wibyuma wimpimbano ufite ibyiza byo gukomera cyane, kwihanganira kwambara neza, ntavunika, kwambara kimwe nibindi. Umupira wibyuma uhimbano Byinshi bikoreshwa mubirombe bitandukanye, inganda za sima, sitasiyo yamashanyarazi, inganda zimiti nizindi nganda. Kugirango tumenye neza imikorere yo gusya umupira, twashyizeho uburyo bwiza bwo gupima ubuziranenge, kugenzura ubuziranenge no kugenzura ibikoresho. Twabonye kandi ISO 9001: 2008 Icyemezo cya sisitemu yubuziranenge mpuzamahanga. Twizeye ubufatanye bwawe.
Junda isosiyete ikoraφ 20 kugezaφ Imipira yicyuma 150 yahimbwe, duhitamo ibyuma byujuje ubuziranenge, ibyuma bya karubone nkeya, ibyuma bya manganese ndende, karubone ndende hamwe nicyuma kinini cya manganese nkibikoresho fatizobyakozwe nuburyo bwo guhimba inyundo.Duhitamo ibyuma byujuje ubuziranenge nk'ibikoresho fatizo, kandi tugakoresha ibikoresho bigezweho, uburyo budasanzwe bwo gutunganya ubushyuhe hamwe na sisitemu ihamye yo kugenzura ubuziranenge kugirango tumenye neza imikorere myiza yimipira yibyuma mubukomere muri rusange. ubukana bwo hejuru bugera kuri 58-65HRC, ubukana bwijwi bugera kuri 56-64HRC.Gukwirakwiza gukomeye ni kimwe, ingaruka zikomeye ni 12J / cm², kandi igipimo cyo kumeneka kiri munsi ya 1%. Ibihimbano byumupira wibihimbano: ibirimo karubone is0.4-0.85, ibirimo manganese is0.5-1.2, chromium is 0.05-1.2,Turashobora kubyara ubunini butandukanye ukurikije abakiriya's.Twabonye kandi ISO 9001: 2008 Icyemezo cya sisitemu yubuziranenge mpuzamahanga.
