Kwa chitsulo chosungunula kapena ng'anjo yamagetsi yosungunula m'mafakitale oponyera, maziko a teknoloji ya carburizing ndi kugwiritsa ntchito sulfure yochepa, nayitrogeni yochepa, porosity yambiri.carburizing wothandizira.

Petroleum coking carburizer madera omwe amapanga Liaoning, Tianjin, Shandong ndi malo ena.Pakati pawo, Liaohe Oilfield ndiye gwero ladziko lapansi lamafuta otsika a sulfure, motero sulfure yomwe ili mu petroleum coke ndiyotsika kwambiri.

The porosity wacarburizing wothandiziraimakhalanso ndi gawo lofunikira pakupanga kwa carburizing komanso kuchuluka kwa mayamwidwe a carburizing agent.Kupyolera mukupanga, ma pores a petroleum coke carburizing agent onse amatsegulidwa kuti achulukitse malo enieni a carburizing agent, ndipo chinthucho chimakhala ndi permeability kwambiri ndipo chimatha kusungunuka mwachangu muchitsulo, kuti chiwonjezeke mayamwidwe ndikusunga bwino carburizing. .
