Mefuta e tloaelehileng ea li-carburizer naheng ea China e kenyelletsa Moemeli oa Graphitization Carburizing, Calcined Petroleum Coke le Calcined Anthracite Coal,
Lisebelisoa tse tala tsa moemeli oa carburizing ea malapeng ke masala a boima a oli nakong ea ho hloekisoa ha peterole bakeng sa ho pheha, e leng petroleum coke le asphalt coke. Coke e tala ea petroleum e calcined ka calcined petroleum coke. Graphite carburizing agent e fumanoa ka graphitization ea petroleum coke e tala. Graphitization e ka fokotsa litaba tsa litšila, ea eketsa khabone le ho fokotsa sebabole.
Carburizing agent e sebelisoa haholo indastering ea ho etsa tšepe, ho lahla, ho qhibilihisa le tse ling. Tšebeliso ea carburizing agent ka ho lahlela e ka eketsa haholo palo ea litšepe, ea fokotsa palo ea tšepe kapa ho se be le tšepe ea kolobe. Carburizing agent e ka ntlafatsa kabo ea graphite, ea khothaletsa graphitization ea tšepe e entsoeng ka tšepe, ea eketsa nucleus ea graphite ea kristale le bolo e ntle ea graphite ea tšepe e qhibilihisitsoeng, e le ho etsa hore e ajoe ka mokhoa o ts'oanang ka har'a matrix le ho ntlafatsa boleng ba lihlahisoa.
Calcined petroleum coke e sebelisoa haholo indastering ea aluminium. Ts'ebetsong ea ho etsa tšepe, Mashala a Calcined Anthracite a ka eketsoa joalo ka moemeli oa carburizing.
Carbon Additive/Carbon Raiser e boetse e bitsoa "Calcined Anthracite Coal", kapa "Gas Calcined Anthracite Coal".
Lintho tse ka sehloohong tse tala ke anthracite ea boleng bo phahameng e ikhethang, e nang le tšobotsi ea molora o tlaase le sebabole se tlaase. Keketso ea khabone e na le litšebeliso tse peli tsa mantlha, e leng joalo ka mafura le tlatsetso.
