Kodi carburant ndi chiyani?
Pali mitundu yambiri ya carburizers, kuphatikizapo malasha, graphite zachilengedwe, graphite yokumba, coke ndi zipangizo zina za carbon.Zizindikiro zakufufuza ndi kuyeza ma carburizer ndizomwe zimasungunuka, liwiro losungunuka, ndi poyatsira.Zizindikiro zazikulu za mankhwala ndi Carbon, sulfure, nitrogen, ndi hydrogen.Sulfure ndi haidrojeni ndi zinthu zovulaza.Pakati pa mitundu ina, nayitrogeni ndi chinthu choyenera.Popanga chitsulo chopangidwa ndi chitsulo, carburizer yokhala ndi khalidwe labwino imanenedwa Chofunika kwambiri ndi graphitized recarburizer, chifukwa pansi pa kutentha kwakukulu, maatomu a carbon amapangidwa mu mawonekedwe a microscopic a graphite, motero amatchedwa graphitization.Carburizers amatha kuchulukitsa kwambiri kuchuluka kwa zitsulo zomwe zimagwiritsidwa ntchito poponya, ndikuzindikira kugwiritsa ntchito chitsulo chochepa kapena chosakhala cha nkhumba.
Carburizer ntchito:
Carburizer ndi chinthu chofunikira chosungunula chitsulo chosungunula mu ng'anjo yolowera, ndipo mtundu wake ndi kagwiritsidwe ntchito kake zimakhudza kwambiri chitsulo chosungunuka.Kuponyedwa kuli ndi zofunika zina za kaboni, kotero ma carburizer amagwiritsidwa ntchito kuonjezera mpweya wa carbon mu chitsulo chosungunuka.Zida zomwe zimagwiritsidwa ntchito kwambiri pakusungunula ndi chitsulo cha nkhumba, zitsulo zotsalira, ndi zida zobwezerezedwanso.Ngakhale kuti kaboni wa chitsulo cha nkhumba ndi wokwera, mtengo wake ndi wokwera kwambiri kuposa wazitsulo zachitsulo.Choncho, kugwiritsa ntchito recarburizer kumatha kuonjezera kuchuluka kwa zitsulo zowonongeka ndi kuchepetsa chitsulo cha nkhumba, kuti muchepetse mtengo wa castings.
Kugawika kwa carburizers:
Graphite recarburizer imatanthawuza kusintha kwa ma cell a zinthu za kaboni kudzera kutentha kwambiri kapena njira zina, ndipo pamakhala dongosolo lokhazikika.Mu dongosolo la mamolekyuwa, mtunda wa molekyulu wa kaboni ndi wokulirapo, womwe umathandizira kuwola ndikupangika muchitsulo chosungunuka kapena chitsulo.nyukiliya.Ma graphite recarburizer omwe pano ali pamsika nthawi zambiri amachokera ku njira ziwiri, imodzi ndi kudula zinyalala kwa ma elekitirodi a graphite, ndipo inayo ndi yopangidwa ndi graphitization ya petroleum coke pa madigiri 3000.
Carburizer yochokera ku malasha ndi chinthu chomwe chimawotchedwa pansi pa kutentha kwambiri pogwiritsa ntchito anthracite ngati zopangira.Ili ndi mawonekedwe amtundu wa carbon wokhazikika, kukana kwa okosijeni wamphamvu komanso kutsika kwazinthu zovulaza.Itha kugwiritsidwa ntchito ngati chochepetsera pakusungunula.Panthawi yopanga zitsulo za ng'anjo ya arc, coke kapena anthracite akhoza kuwonjezeredwa ngati carburizer pamene akulipira.
