1, pesvedzero yecarburizing agent particle size

Kushandiswa kwecarburizing agentCarburizing process inosanganisira dissolution diffusion process uye oxidation kurasikirwa maitiro, carburizing mumiriri weakasiyana particle size, dissolution diffusion rate uye oxidation kurasikirwa mwero wakasiyana, uye carburizing agent absorption rate inoenderana nekunyungudutswa kwecarburizing ajenti yekukura kwekuwedzera uye oxidation tekinoroji kurasikirwa kuverenga kumhanya kwe kutungamira kwakazara, kazhinji, carburizing agent zvidimbu zvidiki, Dissolution reaction speed inokurumidza, kurasikirwa uye kumhanya kwakakura;Iyo carburizer ine yakakura particle size, inononoka kunyungudika mwero uye kudiki kurasikirwa kuwedzera mwero.

2, pesvedzero yesimbi yemvura inosimudzira pachiyero chekunyura checarburizing agent

Kusuduruka kunokurudzira kunyungudika uye kupararira kwekabhoni kudzivirira kupisa kwesimbi inoyangarara pamusoro pemvura.Pamberi pecarburizing agentinogona kunyungudika zvachose, nguva yekukurudzira yakareba uye chiyero chekutora chakakwira.Kukurudzira kunogona zvakare kupfupisa nguva yekuvharisa simbi, kupfupisa kutenderera kwekugadzira, uye kudzivirira kupisa kwezvinhu zvinosanganisa musimbi inopisa.Nekudaro, nguva yekukurudzira yakarebesa, iyo kabhoni yakanyungudika mumvura yakabvongodzwa simbi inozowedzera kurasikirwa kwekabhoni kune mhedzisiro huru.Naizvozvo, iyo yakakodzera yekusanganisa nguva yekutonga kwesimbi yemvura inofanirwa kuve yekuona kuti carburizer inogona kunyungudika zvachose.

　　3, pesvedzero yetembiricha pachiyero chekunyura che carburizer

Zvinoenderana nekuongorora kubva pamaonero echikamu mechanics uye thermodynamics, iyo oxidation yesimbi yemvura ine hukama nekuenzana kwekushanda tembiricha shanduko yeC-Si-O system, kureva, iyo O mune yemvura iron ichave nekukanganisa kwakashata neC uye Si. .Iyo equilibrium tembiricha inoshanduka nezviri mukati C uye Si.Naizvozvo, kana tembiricha yekushanda yakaenzana iri pamusoro, chiyero chekutorwa kwecarburant chinogona kuderedzwa.Kana iyo carburizing tembiricha iri pazasi peyakaenzana ambient tembiricha, iyo saturated solubility yekabhoni inodzikiswa nekuda kweiyo tembiricha yakadzikira, uye mwero wekuvandudza kwekabhoni kunyungudika uye kupararira kuri kudzikira, saka goho zvakare rakaderera;Carburizing tembiricha pachiyero chekudzora tembiricha, carburizing agent absorption rate yakakwira.

Mutembiricha uye kuumbwa kwekemikari, zvimwe zvinwiwa zvekabhoni zvine mamiriro akafanana ekusagadzikana kwesimbi.Kuparara kwekabhoni musimbi yakakandwa ye ([C] % = 1.30.0257 t - 0.31% [Si] 0.33 [P] % 0.45 [% S] 0.028 [Mn %] yekushisa kwesimbi inopisa (t). dhigirii rekuzadza, iyo yakawanda carburizer inowedzerwa, iyo yakareba nguva inodiwa yekuparara uye kupararira, iyo yakakura kurasikirwa inoenderana, uye mwero wekunyura uchaderedzwa.

Kana iyo simbi yemvura yakakwira mune yekutanga kabhoni yemukati, kunyudzwa kweiyo yakanyungudika carburant inononoka, kunyudzwa kweiyo carburant kushoma, uye kupisa kwakakura kwakaderera.Kana iyo yekutanga kabhoni yemukati yesimbi yemvura yakadzikira, mamiriro acho anodzoserwa kumashure.Pamusoro pezvo, iyo silicon nesarufa mumhinduro yesimbi yaitadzisa kutorwa kwekabhoni uye yakaderedza kunyudzwa kwekabhoni enhancers.Manganese inobatsira kunyura kabhoni uye inowedzera kutorwa kwekabhoni zvinowedzera.Panyaya yedhigirii rekuita, silicon ndiyo yakakura, manganese yechipiri, kabhoni, sarufa ishoma.Naizvozvo, mune chaiyo kugadzirwa uye budiriro muitiro, manganese inofanira kuwedzerwa kutanga, ipapo kabhoni, uye ipapo nesilicon.
