Uburyo bwo gutunganya ubushyuhe bwicyuma burimo inzira eshatu: gushyushya, kubika, no gukonjesha. Rimwe na rimwe hari inzira ebyiri gusa: gushyushya no gukonjesha. Izi nzira zirahuzwa kandi ntizishobora guhagarikwa.
1.Gushyushya
Gushyushya nimwe mubikorwa byingenzi byo kuvura ubushyuhe. Hariho uburyo bwinshi bwo gushyushya uburyo bwo kuvura ubushyuhe. Icyambere kwari ugukoresha amakara namakara nkisoko yubushyuhe, hanyuma ugakoresha ibicanwa byamazi na gaze. Gukoresha amashanyarazi bituma gushyushya byoroshye kugenzura kandi nta byangiza ibidukikije. Aya masoko yubushyuhe arashobora gukoreshwa mubushuhe butaziguye, cyangwa gushyushya butaziguye binyuze mumunyu ushongeshejwe cyangwa icyuma, cyangwa se ibice bireremba hejuru.
Iyo icyuma gishyushye, igihangano gikorerwa mu kirere, kandi okiside na decarburisation bikunze kubaho (ni ukuvuga ko ibintu bya karubone hejuru yicyuma bigabanuka), bigira ingaruka mbi cyane kumiterere yubuso bwa ibice nyuma yo kuvura ubushyuhe. Kubwibyo, ibyuma bigomba gushyukwa mukirere cyagenzuwe cyangwa ikirere kirinda, umunyu ushongeshejwe, no mu cyuho. Gushyushya birinda birashobora kandi gukorwa muburyo bwo gutwikira cyangwa gupakira.
Ubushyuhe ni kimwe mubintu byingenzi byerekana uburyo bwo gutunganya ubushyuhe. Guhitamo no kugenzura ubushyuhe bwo gushyuha nikibazo nyamukuru kugirango harebwe ubwiza bwo kuvura ubushyuhe. Ubushyuhe bwo gushyuha buratandukanye bitewe nicyuma gitunganyirizwa hamwe nintego yo kuvura ubushyuhe, ariko muri rusange birashyuha hejuru yubushyuhe runaka buranga impinduka kugirango ubone ubushyuhe bwo hejuru. Byongeye, guhinduka bisaba igihe runaka. Kubwibyo, iyo ubuso bwibikorwa byicyuma bigeze kubushyuhe bukenewe, bigomba kubikwa kuri ubu bushyuhe mugihe runaka kugirango ubushyuhe bwimbere ninyuma buhoraho hamwe na microstructure ihinduka byuzuye. Iki gihe cyigihe cyitwa igihe cyo gufata. Iyo ukoresheje ingufu nyinshi-zishyushye hamwe no kuvura ubushyuhe bwo hejuru, umuvuduko wo gushyuha urihuta cyane kandi muri rusange ntamwanya wo gufata, mugihe umwanya wo gufata imiti yubushyuhe akenshi uba muremure.
Ubukonje
Gukonjesha kandi ni intambwe y'ingenzi mu gutunganya ubushyuhe. Uburyo bwo gukonjesha buratandukanye bitewe nibikorwa, cyane cyane kugenzura igipimo cyo gukonja. Mubisanzwe, annealing ifite umuvuduko ukonje cyane, mubisanzwe bifite umuvuduko ukonje, kandi kuzimya bifite umuvuduko ukonje. Ariko, haribisabwa bitandukanye bitewe nubwoko butandukanye bwibyuma. Kurugero, ibyuma bikomye ikirere birashobora gukomera ku kigero kimwe cyo gukonjesha nkibisanzwe.
