Kugirango utezimbere ubuso bukomeye no kwambara birwanya16Mn imiyoboro y'urukiramende, kuvura hejuru, nka flame yubuso, kuzimya inshuro nyinshi kuzimya, kuvura ubushyuhe bwimiti, nibindi bigomba gukorwa kubitereko byurukiramende.Muri rusange, igice kinini cyo hejuru kandi giciriritse kizimya, kandi ubushyuhe bwo gushyuha ni dogere 850-950.Kubera ubushyuhe buke bwumuriro, umuvuduko wo gushyushya ntugomba kwihuta cyane.Bitabaye ibyo, gushonga ibice no kuzimya bizagaragara.Kuzimya inshuro nyinshi bisaba ko matrix isanzwe ari pearlite.Gutera amazi cyangwa polyvinyl alcool ikonje.Ubushyuhe ni 200-400 ℃, naho ubukana ni 40-50hrc, bushobora kwemeza ubukana no kwambara birwanyakarehejuru.
Ingingo z'ingenzi zikurikira zizamenyekana mugihe uzimye16Mn kare:
(1)Umuyoboro muremure ntushobora gushyuha uhagaritse mu itanura ryumunyu cyangwa itanura ryiza uko bishoboka kwose, kugirango bigabanye ihindagurika ryatewe nuburemere bwacyo.
(2)Iyo gushyushya imiyoboro ifite ibice bitandukanye mu itanura rimwe, imiyoboro mito igomba gushyirwa kumpera yinyuma y itanura, kandi imiyoboro minini hamwe nuduce duto bigomba kugenwa ukundi.
(3)Amafaranga yo kwishyuza agomba guhuzwa nurwego rwingufu zitanura.Iyo ingano yo kugaburira ari nini, biroroshye kotsa igitutu no kuzamuka kwubushyuhe, kandi igihe cyo gushyuha kigomba kongerwa.
(4)Ubushyuhe bwo kuzimya imiyoboro y'urukiramende rwazimye n'amazi cyangwa brine bizafatwa nk'urugero rwo hasi, kandi ubushyuhe bwo kuzimya amavuta cyangwa umunyu ushongeshejwe byafashwe bifatwa nkurugero rwo hejuru.
(5)Mugihe cyo kuzimya kabiri, igihe cyo gutura muburyo bwa mbere kizimya kigenzurwa hakurikijwe uburyo butatu bwavuzwe haruguru.Igihe cyo kwimuka kuva muburyo bwa mbere bwo kuzimya kugera kumurongo wa kabiri uzimya bigomba kuba bigufi bishoboka, byaba byiza 0.5-2s.
(6)Imiyoboro ifite ubuso bubujijwe okiside cyangwa decarburisation igomba gushyukwa mu itanura ryumunyu wa kalibibasi cyangwa itanura ryikirere.Niba itujuje ibisabwa, irashobora gushyukwa mu itanura rirwanya ikirere, ariko hagomba gufatwa ingamba zo kubarinda.
(7)Nyuma ya 16Mn y'urukiramende rwinjijwe mu buryo buhagaritse mu kuzimya, ntiruzunguruka, ruzamuka hejuru no hasi, kandi ruhagarika kubyutsa uburyo bwo kuzimya.
(8)Iyo ubushobozi bwo gukonjesha ibice bisaba gukomera cyane bidahagije, igice cyose gishobora kwibizwa mugihe cyo kuzimya icyarimwe, kandi ibice birashobora gukonjeshwa no gutera amazi kugirango umuvuduko ukonje.
(9)Igomba gushyirwa ahantu hashyushye neza.Amafaranga yo kwishyuza, uburyo bwo kwishyuza hamwe nuburyo bwo gutondekanya bigomba kwemeza ko ubushyuhe bwo gushyuha ari bumwe, kandi ntibishoboka gutera deformasiyo nizindi nenge.
(10)Iyo ushyushye mu itanura ryumunyu, ntigomba kuba hafi ya electrode kugirango wirinde ubushyuhe bwaho.Intera igomba kuba hejuru ya 30mm.Intera kuva kurukuta rwitanura nuburebure bwimbitse munsi yurwego rwamazi bizaba bingana na 30mm.
(11)Ibyuma byubatswe nicyuma cya karubone birashobora gushyukwa mu itanura rifite ubushyuhe bwo kuzimya cyangwa 20-30 ℃ hejuru yubushyuhe bwo kuzimya.Carbone ndende hamwe nicyuma kinini gishobora gushyuha hafi 600 ℃ hanyuma bikazamurwa kugirango ubushyuhe buzimye.
(12)Ubushyuhe bwo kuzimya burashobora kwiyongera muburyo bukwiye kumiyoboro ifite igorofa ryimbitse, kandi ubushyuhe bwo hasi bwo kuzimya bushobora gutoranywa kumiyoboro ifite igorofa ridakomeye.
(13)Ubuso bwa 16Mn kare ya tube igomba kuba idafite amavuta, isabune nundi mwanda.Ahanini, ubushyuhe bwamazi ntibushobora kurenga 40 ℃.
