Mukufuna kumvetsetsa zomwe carburizing agent ndi yakuthupi, kuyambira pa ulalo wa kumtunda kwa carburizing agent.Pakadali pano, wogwiritsidwa ntchito kwambiri posungira mafuta pamsika ndi calcined petroleum coke carburizing agent ndi graphitized carburizing agent.

1. Kalcined petroleum cokecarburizer ndi petroleum coke yomwe imatenthedwa pa 1250 ℃ kwa maola 48 ndipo imakhala calcined petroleum coke.Pazochitika zonsezi, zonyansa monga zinthu zowonongeka ndi chinyezi cha petroleum coke zimachotsedwa, kotero kuti mpweya wa carbon ukhoza kufika kupitirira 98.5% ndipo zonyansa monga zinthu zowonongeka ndi phulusa zimatha kuchepetsedwa mpaka 1.5%.Carburizing agent agent kuchokera pamawonekedwe a mawonekedwe osakhazikika a coke, kukula kwa chipika chakuda (kapena tinthu tating'ono), zitsulo zonyezimira, tinthu tating'onoting'ono tokhala ndi porous, chinthu chachikulu chomwe chimapangidwa ndi kaboni.

2. Graphitization carburizing wothandizira ndi mankhwala opangidwa kuchokera ku petroleum coke kapena calcined petroleum coke pambuyo pa kutentha kwapamwamba ndi ndondomeko ya graphitization pa 3000 ℃.Kusiyanitsa pakati pa ndondomeko ya calcination ndi ndondomeko ya calcination ndikuti mapangidwe a maselo a carbon amasintha kwambiri, ndipo mapangidwewo ali pakati pa mawonekedwe a amorphous ndi mapangidwe a graphite, omwe ndi osokonezeka kwambiri amorphous.Zojambulajambula za carburizer kuchokera ku maonekedwe a calcined kwambiri zakuda ndi zowala, ndipo zimatha kulemba mawu bwino papepala.

Mwachidule, zinthu za carburizer zimangowoneka ngati mtundu wamtundu wa kaboni pakati pa kapangidwe ka amorphous ndi kapangidwe ka graphite ka zinthu za kaboni.
