1, chikoka cha carburizing wothandizira tinthu kukula

Kugwiritsa ntchitocarburizing wothandiziraCarburizing process imaphatikizapo kusungunuka kwa diffusion ndi kutayika kwa oxidation, carburizing agent of different particle size, dissolution diffusion rate and oxidation loss rate is different, and carburizing agent mayamwidwe amatengera kusungunuka kwa carburizing agent pakukula kwa diffusion rate and oxidation technology loss calculation of kasamalidwe zambiri, carburizing wothandizila particles yaing'ono, Kusungunuka anachita liwiro ndi kudya, imfa ndi liwiro lalikulu;Carburizer ili ndi kukula kwakukulu kwa tinthu, kusungunuka kwapang'onopang'ono komanso kutayika pang'ono.

2, chikoka cha chitsulo chamadzimadzi chomwe chikuyambitsa mayamwidwe a carburizing agent

Kusokonezeka kumalimbikitsa kusungunuka ndi kufalikira kwa mpweya kuti zisawotchedwe chitsulo choyandama pamwamba pa madzi.Pamaso pacarburizing wothandiziraimatha kusungunuka kwathunthu, nthawi yolimbikitsa ndi yayitali komanso kuchuluka kwa mayamwidwe ndikwambiri.Kugwedeza kungathenso kufupikitsa nthawi ya kutsekemera kwa carburizing, kufupikitsa nthawi yopangira, komanso kupewa kuyaka kwa zinthu za alloying muzitsulo zotentha.Komabe, kuyambitsa nthawi yayitali kwambiri, kaboni wosungunuka mumadzi osonkhezera chitsulo amakulitsa kutayika kwa kaboni kumakhala ndi zotsatira zabwino.Choncho, kasamalidwe koyenera ka nthawi yosakaniza chitsulo chamadzimadzi chiyenera kukhala kuonetsetsa kuti carburizer ikhoza kusungunuka kwathunthu.

　　3, mphamvu ya kutentha pamayamwidwe a carburizer

Malinga ndi kusanthula kwa maganizo a tsankho zimango ndi thermodynamics, ndi makutidwe ndi okosijeni wa chitsulo madzi chikugwirizana ndi mgwirizano ntchito kutentha kusintha kwa C-Si-O dongosolo, ndiko kuti, O mu madzi chitsulo adzakhala ndi chokhwima zochita ndi C ndi Si. .Kutentha kofanana kumasintha ndi zomwe zili mu C ndi Si.Choncho, pamene kutentha kwa ntchito yofanana kuli pamwamba, mlingo wa mayamwidwe wa carburant ukhoza kuchepetsedwa.Pamene kutentha kwa carburizing kuli pansi pa kutentha kozungulira, kusungunuka kwa carbon kumachepetsedwa chifukwa cha kutentha kochepa, ndi kukula kwa mpweya ndi kufalikira kwa mpweya kumachepa, kotero zokolola zimakhala zochepa;Kutentha kwa carburizing pamlingo wowongolera kutentha, kuchuluka kwa mayamwidwe a carburizing ndikwambiri.

4, chikoka cha kuwonjezera kwa carburizing wothandizira

Kutentha ndi kupangidwa kwa mankhwala, zakumwa zina za carbon zimakhala ndi chikhalidwe chofanana cha kuchuluka kwa iron saturation.Kusungunuka kwa carbon mu chitsulo chosungunuka kwa ([C] % = 1.30.0257 t - 0.31% [Si] 0.33 [P] % 0.45 [% S] 0.028 [Mn %] pa kutentha kwachitsulo (t). kuchuluka kwa machulukitsidwe, carburizer ikawonjezeredwa, nthawi yayitali yofunikira kuti isungunuke ndi kufalikira, kutayika kwakukulu kofananirako, ndipo kuchuluka kwa mayamwidwe kumachepetsedwa.

5, chikoka cha chitsulo liquefaction mankhwala zikuchokera pa mlingo mayamwidwe carburizer

Pamene chitsulo chamadzimadzi chimakhala chochuluka mu carbon content, mayamwidwe a carburant osungunuka amakhala pang'onopang'ono, mayamwidwe a carburant amakhala ochepa, ndipo kuyaka kwakukulu kumakhala kochepa.Pamene mpweya woyamba wa chitsulo chamadzimadzi uli wochepa, zinthu zimasintha.Kuphatikiza apo, silicon ndi sulfure muzitsulo zachitsulo zimalepheretsa kuyamwa kwa kaboni ndikuchepetsa kuchuluka kwa mayamwidwe a carbon enhancer.Manganese amathandizira kuyamwa kwa kaboni ndikuwonjezera kuchuluka kwa mayamwidwe a carbon enhancers.Pankhani ya digiri ya chikoka, silicon ndiye wamkulu, manganese wachiwiri, kaboni, sulfure ndi wocheperako.Choncho, popanga ndi chitukuko chenichenicho, manganese ayenera kuwonjezeredwa poyamba, ndiye carbon, ndiyeno silicon.
