Carbonization mataki:
1, Well-irin tanda zafin jiki ya kai carburizing zafin jiki bayan, rubuta zuwa zafin jiki lokaci, canza carburizing drops, ci gaba da zafin jiki fitarwa 30 ~ 45min, dauki gas nazari, lokacin da tanda gas CO2 girman rabo (0.5%), wato shiga carburizing mataki, canza carburizing drops, kashe kananan fitarwa rami, sa ƙonawa wuta tsawon har zuwa 100 ~ 150mm, ƙonawa wuta ne haske rawaya, babu haske Mars burst, bude U-irin matsin lamba ma'auni, sa tanda matsin lamba sarrafawa a 250 ~ 400Pa.
2, daga waje samfurin rami sanya biyu waje samfurin, waje samfurin sanya a cikin zurfin gabaɗaya daga tandu 100 ~ 200mm, waje gwajin sandunan rami amfani da asbestos igiya sanya a cikin ƙarfi, don hana leakage gas da kuma zafi.
3, duba sau daya a kowane 15min da kuma tudu zafin jiki, tudu matsin lamba da kuma daidaita drop drop. Yankin canji ba zai wuce ± 5 drops / min na ƙididdigar da aka ƙayyade ba, yayin da aka bincika yanayin carbonation da kuma sarrafa ƙididdigar CO2, H2O, O2 a cikin yanayi. Lokacin da aka yi amfani da methanol, kerosene a matsayin infiltrant, da gasi abun ciki iko a cikin:
ФCnH2n+2 ФCnH2n ФCO ФH2 ФCO2 ФO2 ФN2
5 ~ 15 ≤0.5 15 ~ 25 40 ~ 60 ≤0.5 ≤0.5
4, karfi infiltration mataki na tsire-irin tandu gas karfin zai iya fiye da 0.2% ~ 0.4% na buƙatun farfajiyar carbon da yawa rabo darajar.

Matsayin yaduwa:
1, Strong infiltration mataki na infiltration gudun za a iya kimanta da 0.15 ~ 0.25mm / h, low carbon karfe dauki ƙasa iyaka, chromium molybdenum karfe dauki sama iyaka, kimanta da infiltration layer Shenzhen Special Zone kai matsakaicin ƙasa iyaka na fasaha bukatun, fitar da wani waje gwajin sanda, bisa ga waje gwajin sanda layer zurfin da kuma farfajiyar carbon ingancin rabo darajar, ƙayyade ko za a iya shiga yaduwa mataki da kuma yaduwa da infiltration drop. Don kayan aiki da ba su buƙatar yaduwa, za a iya fara sanyaya.
2, a lokacin yaduwa, carburization gas rage, kariya gas yawa, yaduwa lokaci ne a ka'ida 1/3 ~ 1/4 na karfi permeation lokaci, carbon karfe ne kusan 1/4 ~ 1/5, amma takamaiman yanayin takamaiman bincike.
3, watsawa lokacin tandu matsin lamba gabaɗaya sarrafawa a 50 ~ 100Pa.
4, furnace gas carbon kadan sama da ƙananan iyaka na farfajiyar carbon mataki (mass rabo) darajar da aka tsara da fasaha bukatun.
