I-1, impembelelo ye-agent ye-carburizing ubungakanani besuntswana

Ukusetyenziswa kwecarburizing agentInkqubo ye-carburizing ibandakanya inkqubo yokuchithwa kwe-diffusion kunye nenkqubo yokulahleka kwe-oxidation, i-agent e-carburizing yobungakanani bamasuntswana ahlukeneyo, isantya sokuchithwa kwe-diffusion kunye nesantya selahleko ye-oxidation yahlukile, kwaye izinga lokufunxa i-agent ye-carburizing lixhomekeke kwi-arhente yokuchithwa kwe-carburizing kwizinga lophuhliso lokusasaza kunye ne-oxidation yelahleko yesantya sokubala ulawulo olubanzi, ngokubanzi, carburizing agent amasuntswana amancinci, Dissolution reaction speed ngokukhawuleza, ilahleko kunye nesantya sikhulu;I-carburizer inobungakanani besuntswana elikhulu, isantya sokuchithwa kancinci kunye nesantya esincinci sokunyuka kwelahleko.

I-2, impembelelo yentsimbi engamanzi ivuselela kwisantya sokufunxa se-agent carburizing

Ukuphazamiseka kukhuthaza ukunyibilika kunye nokusasazwa kwekhabhoni ukuthintela ukutshiswa kwentsimbi edada phezu kolwelo.Ngaphambi kwecarburizing agentinokuchithwa ngokupheleleyo, ixesha elishukumisayo lide kwaye izinga lokufunxa liphezulu.Ukuvuselela kunokunciphisa ixesha lokufakwa kwe-carburizing, ukunciphisa umjikelo wemveliso, kwaye uthintele ukutsha kwezinto ezixutywayo kwintsimbi eshushu.Nangona kunjalo, ixesha lokuvuselela lide kakhulu, i-carbon inyibilika kwi-liquid evuselelwe isinyithi iya kwandisa ukulahleka kwekhabhoni kunempembelelo enkulu.Ke ngoko, ulawulo olufanelekileyo lwexesha lokuxuba lwentsimbi engamanzi kufuneka lube kukuqinisekisa ukuba i-carburizer inokuchithwa ngokupheleleyo.

　　3, ifuthe lobushushu kwisantya sokufunxa kwe-carburizer

Ngokohlalutyo olusuka kwimbono yobuchwephesha obungaphelelanga kunye ne-thermodynamics, i-oxidation ye-iron elulwelo inxulumene nokutshintsha kobushushu bokusebenza ngokulinganayo kwenkqubo ye-C-Si-O, oko kukuthi, i-O kwintsimbi engamanzi iya kuba neempembelelo ezimbi kunye ne-C kunye ne-Si. .Ubushushu bokulingana butshintsha kunye nomxholo we-C kunye ne-Si.Ngoko ke, xa iqondo lokushisa elilinganayo liphezulu, izinga lokufunxa i-carburant lingancitshiswa.Xa ubushushu be-carburizing bungaphantsi kobushushu be-ambient equilibrium, ukunyibilika kwekhabhoni kuncitshiswe ngenxa yobushushu obuphantsi, kwaye izinga lophuhliso lokunyibilika kwekhabhoni kunye nokusabalalisa liyehla, ngoko ke isivuno sisezantsi;Ubushushu beCarburizing kwiqondo lobushushu lokulawula ulungelelwaniso, izinga lokufunxa iarhente ye-carburizing liphezulu.

I-4, impembelelo yokongezwa kwe-arhente ye-carburizing

Kwiqondo lobushushu kunye nokwakheka kweekhemikhali, ezinye iilwelo zekhabhoni zinemeko efanayo yoxinzelelo lokugcwala kwentsimbi.Ukutshatyalaliswa kwekhabhoni kwintsimbi etyhidiweyo ye ([C] % = 1.30.0257 t - 0.31% [Si] 0.33 [P] % 0.45 [% S] 0.028 [Mn %] kubushushu bentsimbi eshushu (t). iqondo lokugcwala, kokukhona kongezwa i-carburizer, ixesha elide elifunekayo lokuchithwa kunye nokusabalalisa, ilahleko enkulu ehambelanayo, kunye nesantya sokufunxa siya kuncitshiswa.

I-5, impembelelo ye-iron liquefaction chemical composition kwizinga lokufunxa kwe-carburizer

Xa i-iron yolwelo iphezulu kumxholo wokuqala wekhabhoni, izinga lokufunxa kwe-carburant enyibilikileyo licotha, izinga lokufunxa kwe-carburant lincinci, kwaye ukutshisa okukhulu kuphantsi.Xa umxholo wokuqala wekhabhoni wentsimbi engamanzi uphantsi, imeko iyatshintshwa.Ukongeza, i-silicon kunye nesulfure kwisisombululo sentsimbi ithintele ukufunxwa kwekhabhoni kwaye yanciphisa izinga lokufunxa kwezixhasi zekhabhoni.IManganese inegalelo ekufunxeni kwekhabhoni kwaye yonyusa izinga lokufunxa kwezixhasi zekhabhoni.Ngokweqondo lempembelelo, i-silicon inkulu, i-manganese yesibini, i-carbon, isulfure incinci.Ngoko ke, kwinkqubo yokuvelisa kunye nophuhliso lwangempela, i-manganese kufuneka yongezwe kuqala, emva kwekhabhoni, kunye ne-silicon.
