Ibyiciro bitatu n'ingaruka muburyo budakora

Muburyo bwo guhiga bwibyuma bitagira ingano, 'Kumurongo ' ni inzira yingenzi. Guhuza bisaba gukoresha itanura rya Anneling, itanura ryaka rikoreshwa cyane cyane muguvura ubushyuhe bwuzuye bwibyuma bidafite ikibazo mukirere kirinda. Imikorere iratandukanye, ibisabwa ku itanura ryiza cyane riratandukanye, kandi inganda zivuriro ntabwo arimwe. Gahunda isanzwe yubushyuhe ya 300 Urukurikirane Austenitic Umuyoboro wa Steel udafite ibyuma nta buvuzi bwo gukemura. Urufunguzo rwumuhanda wo kuvura ubushyuhe rwihuse, kuva ku ya 1050 kugeza 1150 ° kuringaniza ubushyuhe buke mu gihe gito cyo gushyuza imiyoboro ya Austelite, bityo akaba yarashonje cyane mu gihimbano, bityo akaba yarashonje cyane mu gihimbano cyane ahinnye cyane kugira ngo abone imiterere yuzuye.

Kandi, ibyiciro bitatu bya 'binnealing ' bizatuma hejuru yicyuma cyawe kiraramba kandi biramba. Ubwa mbere, gushyushya stage, umuyoboro wicyuma utagira ikinanga uri mu itanura rifunze, kandi ni ngombwa kwemeza ko imyanya ya inlet na outlet yabikwaga kandi nta kibuga cyashyizwe ahagaragara. Kuberako yashyutswe mu kugabanya umwuka wa gaze ya inert na hydrogène isanzwe, ubushyuhe runaka buragerwaho, kandi ibinyampeke bigarukira kumyanya imwe kandi nziza. Icya kabiri, icyiciro cyo kugenzura, ubushyuhe bwumuyoboro w'icyuma utagira ingano kandi uhagaze mugihe runaka binyuze mu gice cyo kwishyuza, kugirango ukureho neza ikibazo cya chromium ya chromium kandi wirinde ibisekuru byo kubungabunga ibicuruzwa. Umuyoboro w'icyuma nyuma yo kuvura neza ufite imitungo myiza ya mashini na ruswa. Icyiciro cya gatatu, gukonjesha, umuyoboro wicyuma utagira ikinamico ukoresha hydrogen mu itanura rifunze, nimpamvu yo gutwika hydrogen hamwe na desipation ntoya no kugabanuka kwubushyuhe, kandi igahabwa uburebure butagira okiside hamwe no kurwanya ruswa.

Muburyo bwo gukomera, hari kandi ibisabwa bimwe kubitanura bikabije, kandi byitabwaho kugirango twishyure kurinda itanura ritemba. Itanura rya anneiel ikoresha hydrogène nka gaze ikingira. Iyo hydrogène imaze kumeneka, birashobora guteza akaga kuzamuka no kwegeranya mumiterere yumunara. Tugomba rero gufata ingamba zijyanye kugirango umutekano.
