Iyo oxidation yeKukanganwirainonyanya kukanganiswa nemakemikari emagetsi esimbi ine simba uye zvinhu zvemukati uye zvekunze zvemheni yekudziya (senge muimbi gasi rekuumbwa, kupisa tembiricha, nezvimwewo).
1) Chemical kuumbwa kwezvinhu zvesimbi
Iyo huwandu hweyero yehuwandu hwakaumbwa hunosangana neyakagadzirwa nemakemikari. Iyo yakakwira iyo kabhoni zvemukati yesimbi, iyo shoma oxide chiyero inoumbwa, kunyanya kana kabhoni zvemukati zvinopfuura 0.3%. Izvi zvinodaro nekuti mushure mekunge kabhoni iri oxidized, denderedzwa reMonoxide (CO) gasi rinoumbwa pamusoro peisina chinhu, iyo inoita basa mukurindira iyo audidation yakaenderera mberi. Alloy Steel In Cr, NI, AL, Mo, Si uye Zvimwe Zvekuita Kana Kuumbwa kweiyo Offer Solves, uye zvakanyatsonaka pamusoro pechiso, hachisi nyore kuputsa uye kudzivisa. Kupisa-kupesana kusiri-peeling simbi ndeyekuita simbi ine zvimwe zvezvinhu zviri pamusoro, uye kana zvirimo zveI NI uye CR mumbiru iri 13%? Pa20%, kanenge hapana oxidation inoitika.
2) Furura gasi kuumbwa
Furosi Gasi Kuumbwa ine pesvedzero huru pane kuumbwa kweKukanganisikachiyero, zvakafananaSimbi KukanganwirwaMumhepo yekudziya akasiyana siyana, kuumbwa kwehuremu hakuna kufanana, mune yehusiku chiridzwa gasi, kuumbwa kwechiyero kwakanyanya, kujekesa grey, nyore kubvisa; Mune zvevakarerekera gasi Kuti uderedze kuumbwa uye kubvisa huwandu hweuroxide, kutariswa kunofanirwa kubhadharwa kutongwa kwechiratidzo chegesi kwegasi pane imwe nhanho yekudziya. Kazhinji, kukosheswa kuri pasi pegumi 1000 Kana tembiricha ichidarika 1000
Chimiro chechoto gasi mumurazvo wekupisa choto chinoenderana nehuwandu hwemhepo inopihwa kune iyo mafuta panguva yekubatanidza. Kana iyo yakawandisa coefficience yemvura yakanyanya, iyo mhepo yakanyanya, iyo gwara remuti iri oxidized, iyo simbi oxidey yakawanda, kana iyo yakawandisa mhepo mumvura ndeye 0.4? Pa0.5, gasi rechiratidza rinodzikisira, vachigadzira mamiriro ekudzivirira kudzivirira kuumbwa kweuroyi uye kuzadzisa hapana oxidation kupisa.

3) Kupisa tembiricha
Iyo yekudziya yekudziya zvakare ndiyo chinhu chikuru chekuregerera chiyero, iyo yepamusoro yekudziya yekudziya, iyo yakanyanya kunaka iyo oxidation. Muna 570 ℃? Asati 600 At 950 ℃, oxidation yakakosha kwazvo. Kana iyo Oxidiation chiyero ichi fungidzira kuti ndive 1 pa 900 ° C, 2 pa1000 paCi, 3.5 pa100 ° C, uye 7 pa100 ° C, kuwedzera katatu.
4) Inodzidzisa Nguva
Iyo yakareba iyo nguva yekuparadza yeiyo hope dzehusiku muchoto muvira muvira, uye zvakanyanya kuwanda kwenzara
Uyezve, Billet Billet pakupisa kwakanyanya haangobatwi chete muchoto, asiwo mukukosheswa, kunyangwe tembiriro racho richinge rakakwira, richava mhanya kaviri, asi iyo oxidation chiyero zvishoma nezvishoma nekuderera kweBillet tembiricha.
