Enqubweni yokuncibilikisa insimbi nemikhiqizo yensimbi, ukulahlekelwa kokuncibilikisa kwe-carbon element ensimbini encibilikisiwe kuvame ukwanda ngenxa yezici ezifana nesikhathi sokuncibilikisa kanye nesikhathi eside sokushisa ngokweqile, okuholela ekutheni okuqukethwe kwe-carbon ensimbini encibilikisiwe akukwazi ukufinyelela inani elilindelekile ngokuncibilikisa.
Ukuze kuhlanganiswe inani lekhabhoni elahlekile enqubweni yokuncibilikisa insimbi nensimbi, izinto eziqukethe ikhabhoni ezengeziwe zibizwa ngokuthi i-carburizer.
I-ejenti yokupheka kaphethiloli ingasetshenziswa ekubunjweni kwensimbi empunga, okuqukethwe kwekhabhoni ngokuvamile kungama-96 ~ 99%.
Kunezinhlobo eziningi zezinto zokusetshenziswa ze-carburizing agent, inqubo yokukhiqiza yabakhiqizi be-carburizing agent nayo ihlukile, kukhona i-carbon yokhuni, i-carbon yamalahle, i-coke, i-graphite, njll.
I-carburizer esezingeni eliphezulu ngokuvamile ibhekisela ku-carburizer ene-graphised, ngaphansi kwezimo zokushisa okuphezulu, ukuhlelwa kwama-athomu e-carbon kubonisa isimo se-graphite esincane kakhulu.
Ukwenziwa kwe-graphitization kunganciphisa okuqukethwe kokungcola ku-carburizer, kwandise okuqukethwe kwekhabhoni ku-carburizer futhi kunciphise okuqukethwe kwesulfure.
Kunezinhlobo eziningi ze-carburizer, futhi inkomba yekhwalithi ye-carburizer iyafana. Nansi indlela yokuhlukanisa ikhwalithi ye-carburizer:
1. Okuqukethwe kwamanzi: Okuqukethwe kwamanzi kwe-carburizer kufanele kube phansi ngangokunokwenzeka, futhi okuqukethwe kwamanzi kufanele kube ngaphansi kuka-1%.
2. Okuqukethwe komlotha: Inkomba yomlotha ye-carburizer kufanele ibe phansi ngangokunokwenzeka. Okuqukethwe komlotha kwe-carburizer ye-coke ephethiloli e-calcined kuphansi kakhulu, cishe ku-0.5 ~ 1%.
3, ukuguquguquka: ukuguquguquka kwesimo sezulu kuyingxenye engasebenzi kahle ye-carburizer, ukuguquguquka kwesimo sezulu kuncike ekushiseni kwe-calcination noma i-coke ye-carburizer kanye nenqubo yokwelapha, ukuguquguquka kwesimo sezulu kwe-carburizer okucutshungulwe kahle kungaphansi kuka-0.5%.
4. Ikhabhoni Engaguquki: Ikhabhoni engaguquki yekhabhoni iyingxenye ewusizo kakhulu yekhabhoni, uma inani lekhabhoni liphakeme, kuba ngcono.
Ngokusho kwenani eliqondile le-carbon index ye-carburizer, i-carburizer ingahlukaniswa ngamamaki ahlukene, njengo-95%, 98.5%, 99%, njll.
5. Okuqukethwe kwe-sulfur: Okuqukethwe kwe-sulfur kwe-carburizer kuyisici esibalulekile esiyingozi, futhi uma inani liphansi, kuba ngcono. Okuqukethwe kwe-sulfur kwe-carburizer kuncike kokuqukethwe kwe-sulfur kwempahla eluhlaza ye-carburizer kanye nokushisa kwe-calcining.
