I roto i te hanga o te Ductile Iron (e mohiotia ana ko Ductile Iron), he mea tino nui te whakamahi o nga carburizers kounga teitei ki te whakatutuki i nga ahuatanga e hiahiatia ana o te hua mutunga.Ko te recarburizer e whakamahia nuitia anagraphite petroleum coke (GPC), he mea hanga mai i te petroleum coke na roto i te tukanga whakamahana teitei.

I te wa e whiriwhiri ana i te recarburizer mo te hanga rino ductile, he maha nga mea me whai whakaaro.Ko te mea tino nui o enei mea ko te ihirangi waro pumau, te whanariki, te pungarehu, te ihirangi maatai, te hauota me te hauwai.

Ko te ihirangi waro pumau ko te paheketanga o te waro e toe ana i roto i te graphite petroleum coke i muri i te tahuna o nga putu me te pungarehu.Ko te teitei ake o te ihirangi waro, ka pai ake te recarburizer ki te whakanui ake i te ihirangi waro i roto i te rino whakarewa.graphite petroleum coke ki te ihirangi waro pūmau o te iti rawa 98% e tūtohu ana mo te hanga o te rino ductile.

Ko te whanariki he poke noa i roto i te graphite petroleum coke me tona aroaro ka pa kino ki nga ahuatanga whakamutunga o te rino ngongo.No reira, he mea nui ki te kowhiri i te kaitapa hinu graphite me te iti o te whanariki (he iti iho i te 1%).

Ko te kiko o te pungarehu ko te nui o nga rawa kore-whakangiha kei roto i te graphite petroleum coke.Ko te nui o te pungarehu ka hangaia he para i roto i te oumu, ka piki ake nga utu me te whakaiti i te pai.Koinei te take ka tūtohuhia kia whakamahia te graphite petroleum coke me te ihirangi pungarehu i raro i te 0.5%.

Kei roto i nga mea puhoi he hau, he wai ranei ka puta i te wa e whakawerahia ana te kohu hinu graphite.Ko te nui ake o nga mea e kii ana ka taea e te graphite petroleum coke te tuku hau nui ake, ka puta he porosity ki te hua whakamutunga.No reira, me whakamahi te graphite petroleum coke me te mea he iti iho i te 1.5% te ihirangi maataa.

Ko te ihirangi hauota tetahi atu poke i roto i te graphite petroleum coke e tika ana kia iti ake na te mea ka pa ki nga ahuatanga miihini o te rino maka nodular.graphite petroleum coke ki iti iho i te 1.5% hauota ihirangi he pai mo nodular maka rino hanga.

Ka mutu, ko te ihirangi hauwai tetahi atu take me whai whakaaro i te wa e whiriwhiri ana i te kaikawe waro mo te hanga rino nodular.Ka piki ake nga taumata hauwai ka piki ake te pakaruhanga me te whakaheke i te ngongo.graphite petroleum coke ki te ihirangi hauwai iti iho i te 0.5% pai ake.

Hei whakarāpopototanga, ko te hanga rino nodular e hiahia ana ki te whakatipu waro-kounga teitei e tutuki ana i nga whakaritenga motuhake mo te ihirangi waro pumau, te whanariki, te pungarehu, te mea wariu, te hauota me te hauwai.Ko te whakamahi i te graphite petroleum coke e tutuki ana i enei whakaritenga ka whakarite te hanga o te rino nodular kounga teitei, e mohiotia ana ko Ductil Iron, SG rino ranei.
