Ubwa mbere, ikoreshwa rya carburizing agent muburyo bwa carburizing

1. Carbone, nkimwe mubintu byingenzi mubyuma, biragoye guhinduka kuruta ibindi bintu.Kuberako karubone iba mike cyane kuruta icyuma cyamazi, uburyo bwo kwinjiza buzaba buke cyane nta guhagarika umutima.Mubisanzwe mubyiciro, karubone ukurikije urugero rwo hejuru rwibisabwa, hanyuma utekereze uburyo bwo gushonga indishyi zo gutwika karubone, bityo rero utegereze kugeza igihe ibyuma bisobanutse, ingano ya karubone iba iri murwego rwo hejuru, ndetse ikarenga gato hejuru. imipaka irashobora kandi gukoreshwa kugirango hongerwemo bike (bisukuye, byumye) ibisakuzo biroroshye kubimanura, mumatanura yumuriro ushonga karubone kuruta gukora carburizing biroroshye cyane.

2. Kugaburira uko bikurikirana

Intambwe ya 1: Banza ushyireho umubare munini wamafaranga yo kugaruka (cyangwa usigaranye icyuma gito cyamazi) munsi yitanura, kugirango ibikoresho bishya bishobore kwibizwa mubyuma byamazi, bigabanye okiside.

Intambwe ya 2: Ongeraho ibyuma bishaje, hanyuma wongereho carburizing agent.Muri iki gihe, aho gushonga ibyuma byamazi biri hasi, bishobora gushonga vuba kugirango byongere uburebure bwurwego rwamazi, kuburyo umukozi wa carburizing yinjira mubyuma byamazi.Guhuza carburizing hamwe no gushonga ibyuma ntabwo byongera igihe cyo gushonga kandi bitwara imbaraga nke.Kuberako ubushobozi bwo kugabanya FeO na C burenze ubwa Si na Mn, igihombo cyaka cya Si na Mn kirashobora kugabanuka wongeyeho carburizer mubushyuhe buke.Gerageza gukoresha imifuka ipakira ipakiye hamwe na carburizing agent mu ziko ryamashanyarazi, ntukoreshe agapira ka spade mu itanura ryamashanyarazi, kugirango wirinde ibice byiza byanyunyuzwa numukungugu.

Intambwe ya 3: Igice cyashongeshejwe igice kandi amafaranga yo kugaruka yongeyeho.Kugirango umenye neza ko carburizing agent yakiriwe neza mbere yo gutombora, muriki gihe, itanura ryamashanyarazi rifite ingufu nyinshi (> 600kW / t) ni ingenzi cyane kuko igihe gisabwa cyo gushonga ibikoresho gishobora kuba munsi yigihe gisabwa kugirango umuntu yinjire neza carburizer.Muri icyo gihe, imikorere ikurura itanura ry'amashanyarazi igomba gukoreshwa ku rugero runini mugikorwa cya carburizing agent.

Intambwe ya 4: Niba igipimo cyo gukira kwa carburizing agent no kugenzura ibirimo karubone yibyuma byamazi byizewe, umukozi wa carburizing arashobora kongerwamo ibisakuzo rimwe.Niba utazi neza ko ushobora gusiga 5% ~ 10% byumukozi wa carburizing kugirango winjire kabiri.Iyongera rya kabiri rya carburizing agent ni uguhuza neza karubone (cyangwa inyongera ya karubone yatwitse), igomba kongerwaho nyuma yicyuma cyuma, mbere yo kwinjiza icyuma gisukuye hejuru yicyuma gisukuye neza, uko bishoboka kwose kugirango wirinde ibiyobyabwenge bitwara slag, hanyuma amashanyarazi menshi akoresheje itanura ryamashanyarazi kugirango akure igipimo cyo kwinjiza.

Intambwe ya 5: Ongeramo ferrosilicon nibindi bivanze, gusesengura icyitegererezo, hindura ibigize, bivuye mu ziko.Irinde kubika ibyuma byamazi mubushyuhe bwinshi mugihe kirekire.Kubika igihe kirekire icyuma cyamazi mubushyuhe bwinshi (cyane cyane izirinda igihe kirekire hejuru ya 1450 ℃) biroroshye kuganisha kuri okiside ya karubone, kwiyongera kwa silikoni (dioxyde de silicon iragabanuka) no gutakaza nuclei ya kirisiti mubyuma byamazi .

Babiri, ikoreshwa rya carburizing agent muburyo bwa pack carburizing

Niba ari ngombwa gutwika muri paki, ingano yubunini bwa 100 ~ 300 intego ya carburizing agent irashobora gushirwa munsi yipaki, hanyuma icyuma cyo hejuru cyamazi yo mucyuma kijugunywa muburyo bwa carburizing (cyangwa kongerwaho nicyuma cyamazi gutemba), kandi icyuma gikangurwa rwose nyuma yo gushonga no kwinjiza karubone.Ingaruka ya carburizing muri paki ntabwo ari nziza nkiyo mu itanura, kandi igipimo cyo kwinjiza kiragoye kugenzura.Hatitawe ku gukoresha ikoreshwa rya carburizing cyangwa uburyo bwa carburizing bigomba kugenwa binyuze mubikorwa byo kugerageza umusaruro wa carburizing hamwe nigipimo cyikigereranyo bimaze kugenwa, ntugasimbuze byoroshye ubwoko bwa carburizing agent ninkomoko, niba ushaka kubihindura bigomba gutsinda verisiyo yumusaruro. na none.
