[] Kunconywa ukukhetha i-graphitized petroleum coke njenge-carburizer yensimbi ethambile ngezizathu ezilandelayo:
- Ukwakheka kwamakhemikhali okuhle kakhulu:
- I-graphitized petroleum coke: Ngokuvamile iqukethe i-carbon engaphezu kuka-99.5% kanye ne-sulfur engaphansi kuka-0.05%. Izici ze-carbon ephezulu kanye ne-sulfur ephansi zisiza ukwandisa okuqukethwe kwe-carbon kwe-ductile iron ngenkathi kunciphisa imiphumela emibi ye-sulfur ekuqhumeni kwe-nodular kanye ne-graphitization, ngaleyo ndlela kuvimbele amaphutha ekubunjweni.
- I-calcined anthracite carburizer: Ngokuvamile inokuqukethwe kwekhabhoni okungu-90-93% kanye nokuqukethwe kwesalufu okungu-0.3-0.5%. Okuqukethwe kwekhabhoni okuphansi kanye nokuqukethwe kwesalufu okuphezulu kungandisa okuqukethwe kwesalufu ezindaweni zokubumba, okuthinta umphumela we-nodularization kanye nezakhiwo zokubumba.
- Ukusebenza kahle kokumuncwa okuphezulu:
- I-graphitized petroleum coke: Kuncike ekwelashweni kwe-graphitization yokushisa okuphezulu, ama-athomu e-carbon ahlelwe ngendlela ehlelekile, akha isakhiwo se-graphite esicwebezelayo. Lokhu kwenza kube lula ukuncibilika nokumuncwa okusheshayo ensimbini encibilikisiwe, okuholela ekusebenzeni kahle kwe-carburization ephezulu futhi kwandise ngempumelelo okuqukethwe kwe-carbon kwensimbi encibilikisiwe.
- I-calcined anthracite carburizer: Uma inokuqukethwe okuphansi kwekhabhoni, iyancibilika kancane futhi inokusebenza okuphansi kokumunca, okungandisa isikhathi sokuncibilika futhi kwandise ukusetshenziswa kwamandla.
- Umthelela ekuqhumeni kwamaqhubu kanye ne-graphitization:
- I-graphitized petroleum coke: Okuqukethwe okuphansi kwe-sulfur kunciphisa ukuphazamiseka kwe-ejenti ye-nodularizing, okusiza ekufezeni imiphumela emihle ye-nodularization kanye nesimo se-graphite, ngaleyo ndlela kuthuthukiswe izakhiwo zemishini ze-ductile iron.
- I-calcined anthracite carburizer: Okuqukethwe okuphezulu kwesibabule kungaphazamisa inqubo ye-nodularization, okuthinta i-nucleation kanye nokukhula kwe-graphite, okuholela ezimpahleni zokubumba eziwohlokile.
- Ikhwalithi yokusakaza:
- I-graphitized petroleum coke: Ukuyisebenzisa kuphumela kwikhwalithi ephezulu ye-metallurgical ye-castings, kuthuthukisa ngempumelelo amandla nokuqina kwe-ductile iron futhi kunciphise amaphutha afana nokugoba kanye nokuncishiswa, ngaleyo ndlela kuthuthukiswe izinga lokufaneleka komkhiqizo.
- I-calcined anthracite carburizer: Ngenxa yokuqukethwe kwayo okuphezulu kwesibabule, ingabangela ukubhoboka kwama-castings futhi inciphise izakhiwo zemishini, okuthinta ikhwalithi yokubumba.
- Izindleko zokusebenzisa:
- I-graphitized petroleum coke: Nakuba intengo yayo ingase ibe phezulu kancane kuneye-calcined anthracite carburizer, ukusebenza kwayo okuphezulu kwe-carburizer kunciphisa inani le-carburizer elidingekayo, kwehlisa izindleko zokuncibilikisa. Ngaphezu kwalokho, ithuthukisa ikhwalithi yomkhiqizo futhi yehlisa izinga lokususwa kwe-scrap, okuholela ekwehleni kwezindleko zokusetshenziswa iyonke.
- I-calcined anthracite carburizer: Nakuba intengo yayo iphansi kakhulu, ukusebenza kwayo okuphansi kokumunca kungadinga ukusetshenziswa okwengeziwe, futhi kungathinta ikhwalithi yokukhipha, okuholela ezindleleni zokucubungula eziphezulu ezilandelayo.
