Muburyo bwo gushonga, kubera kunywa nabi cyangwa kwishyurwa bidakwiye hamwe na decarbonisation ikabije nizindi mpamvu, rimwe na rimwe ibirimo karubone mubyuma cyangwa ibyuma bitujuje ibyateganijwe, noneho birakenewe gutwika ibyuma cyangwa ibyuma byamazi.Ibintu byingenzi bikunze gukoreshwa muri karburizasi ni ifu ya anthracite, icyuma cyingurube, ifu ya electrode, ifu ya kokiya ya peteroli, kokiya ya asfalt, ifu yamakara nifu ya kokiya.Ibisabwa kuri carburizer ni uko uko karuboni ihagaze neza, ari byiza, kandi bikagabanya ibirimo umwanda wangiza nk ivu, ibintu bihindagurika na sulferi, nibyiza, kugirango bidahumanya ibyuma.
Gushonga kwa casting bifashisha recarburizer yo mu rwego rwo hejuru nyuma yubushyuhe bukabije bwa kokiya ya peteroli hamwe n’umwanda muke, iyi ikaba ari ihuriro rikomeye mugikorwa cya karubasi.Ubwiza bwa recarburizer bugena ubwiza bwicyuma cyamazi, kandi bugena niba ingaruka zo gushushanya zishobora kuboneka.Muri make, kugabanya ibyuma bigabanya recarburizer bigira uruhare runini.
Iyo ibyuma byose bishaje bishongeshejwe mu itanura ryamashanyarazi, rearburizer yashushanyije irahitamo, kandi recarburizer yashushanijwe mubushyuhe bwinshi irashobora guhindura atome ya karubone kuva muburyo bwambere butajegajega kugeza kumpapuro, kandi urupapuro rwa grafite rushobora kuba rwiza intangiriro ya grafite nucleation kugirango iteze imbere igishushanyo.Kubwibyo, dukwiye guhitamo recarburizer yavuwe hamwe nubushyuhe bwo hejuru.Kubera ubushyuhe bwo hejuru bwo kuvura grafitisiyonike, ibirimo sulfure bibyara gazi ya SO2 ikagabanuka.Kubwibyo, sulfure yibintu byujuje ubuziranenge bwa recarburizer ni bike cyane, muri rusange munsi ya 0,05%, kandi ibyiza ni munsi ya 0.03%.Muri icyo gihe, iki nacyo cyerekana mu buryo butaziguye niba cyaravuwe hamwe n'ubushyuhe bwo hejuru kandi niba gushushanya ari byiza.Niba rearburizer yatoranijwe idashushanyijeho ubushyuhe bwinshi, ubushobozi bwa nucleation ya grafite buragabanuka cyane, kandi ubushobozi bwo gushushanya buracika intege, nubwo urugero rwa karubone rushobora kugerwaho, ariko ibisubizo biratandukanye rwose.
Ibyo bita recarburizer ni ukongera neza karubone mubyuma byamazi nyuma yo kongeramo, bityo rero karubone ihamye ya recarburizer ntigomba kuba mike cyane, bitabaye ibyo kugirango ugere kubintu bimwe na bimwe bya karubone, ugomba kongeramo ibicuruzwa byinshi kuruta hejuru -ibikoresho bya karubone, nta gushidikanya byongera ubwinshi bwibindi bintu bitameze neza muri karburizeri, kugirango icyuma gisukuye kidashobora kugaruka neza.
Amazi ya sulfure, azote na hydrogène ni urufunguzo rwo gukumira umusaruro wa porojene ya azote mu guta, bityo rero azote ya recarburizer irasabwa kuba nkeya bishoboka.
Ibindi bipimo bya recarburizer, nkubunini bwubushuhe, ivu, ihindagurika, uko umubare wa karubone ihamye, niko umubare wa karubone ihamye, bityo rero karubone nyinshi, ibikubiye muri ibyo bice byangiza ntibigomba kuba muremure.
Kuburyo butandukanye bwo gushonga, ubwoko bwitanura nubunini bwitanura ryashongeshejwe, ni ngombwa kandi guhitamo ingano yingirakamaro ya recarburizer, ishobora kuzamura neza igipimo cyo kwinjiza no kwinjiza igipimo cya recarburizer mucyuma cyamazi, kandi ikirinda okiside na gutwika igihombo cya carburizer iterwa nubunini buke cyane.Ingano yacyo ni nziza: itanura 100kg ntiri munsi ya 10mm, itanura rya 500 kg ntiri munsi ya 15mm, itanura rya toni 1.5 ntiri munsi ya 20mm, itanura rya toni 20 ntiri munsi ya 30mm.Mu guhinduranya gushonga, iyo hakoreshejwe ibyuma byinshi bya karubone, recarburizer irimo umwanda muke.Ibisabwa kuri recarburizer ikoreshwa mugukora ibyuma bihinduranya ibyuma ni karubone ihamye, irimo ivu ryinshi, ihindagurika na sulfuru, fosifore, azote nibindi byanduye, hamwe nubunini bwumye, busukuye, buringaniye.Carbone itunganijwe C≥96%, ibirimo bihindagurika ≤1.0%, S≤0.5%, ubuhehere ≤0.5%, ingano ya 1-5mm.Niba ingano yingirakamaro ari nziza cyane, biroroshye gutwika, kandi niba ari mubi cyane, ireremba hejuru yicyuma cyamazi kandi ntibyoroshye kwinjizwa nicyuma gishongeshejwe.Kubijyanye na feri ya induction ingano ya 0.2-6mm, muribyo byuma nibindi byuma byirabura bingana na 1,4-9.5mm, ibyuma bya karubone ndende bisaba azote nkeya, ingano ya 0.5-5mm nibindi.Ibikenewe byihariye ukurikije ubwoko bwitanura bwihariye bwo gushonga ubwoko bwibikorwa nibindi bisobanuro byihariye byo guhitamo no guhitamo.
