Ungakhetha kanjani i-recarburizer ephezulu yokwenza insimbi
Enqubweni yokuncibilikisa, ngenxa yokunqwabelana okungafanele noma ukushaja kanye nokususwa kwe-carburization ngokweqile, ngezinye izikhathi okuqukethwe kwekhabhoni ensimbi noma kwensimbi akuhlangabezani nezidingo ezilindelekile.Ngalesi sikhathi, ikhabhoni kufanele yengezwe ensimbi noma ensimbi encibilikisiwe.Izinto eziyinhloko ezivame ukusetshenziselwa i-carbonization i-anthracite powder, i-carbonized pig iron, i-electrode powder, i-petroleum coke powder, i-pitch coke, i-charcoal powder kanye ne-coke powder.Izidingo zama-recarburizers ukuthi ukuphakama kwekhabhoni engaguquki, kungcono, futhi kwehlisa okuqukethwe kokungcola okuyingozi okunjengomlotha, izinto eziguquguqukayo nesibabule, kungcono, ukuze kungangcolisi insimbi.
Ukuncibilikiswa kokusanhlamvu kusebenzisa izinqamuli zekhwalithi ephezulu ngemuva kokubalwa kwezinga lokushisa eliphezulu kwe-petroleum coke enokungcola okumbalwa, okuyisixhumanisi esibaluleke kakhulu enqubweni yokubuyisela kabusha.Ikhwalithi ye-recarburizer inquma ikhwalithi yensimbi encibilikisiwe, futhi inquma ukuthi umphumela omuhle we-graphitization ungatholakala yini.Kafushane, ukunciphisa ukuncibilika kwensimbi encibilikisiwe kanye nama-recarburizers kudlala indima ebalulekile.
Uma yonke insimbi eyizinsimbi incibilikiswa esithandweni sikagesi, i-graphitized recarburizer iyathandwa.Ngemuva kokwelashwa kwe-graphitization ephezulu yokushisa, ama-athomu ekhabhoni angashintsha kusukela ekuhlelweni kwangempela okungahambi kahle kuya ekuhlelweni kwe-flake, futhi i-flake graphite ingaba njenge-graphite.Ingqikithi engcono kakhulu yomongo, ukuze kube lula ukukhuthazwa kwe-graphitization.Ngakho-ke, kufanele sikhethe i-recarburizer eye yathola i-graphitization yokushisa okuphezulu.Ngenxa yokwelashwa kwe-graphitization yokushisa okuphezulu, okuqukethwe kwesibabule kuncishiswa ukuphunyuka kwegesi ye-SO2.Ngakho-ke, ama-recarburizer ekhwalithi ephezulu aqukethe isibabule esiphansi kakhulu, ama-w ngokuvamile angaphansi kuka-0.05%, futhi ama-w(ama) angcono ngisho angaphansi kuka-0.03%.Ngesikhathi esifanayo, lokhu futhi kuyinkomba engaqondile yokwahlulela ukuthi ingabe iye yathola ukwelashwa kwe-graphitization yokushisa okuphezulu nokuthi ngabe i-graphitization ilungile yini.Uma i-recarburizer ekhethiwe ingakenzi ukwelashwa kwe-graphitization yokushisa okuphezulu, amandla e-nucleation we-graphite azoncishiswa kakhulu, futhi ikhono le-graphitization lizoba buthaka.Ngisho noma inani elifanayo lekhabhoni lingafinyelelwa, imiphumela ihluke ngokuphelele.
Okubizwa ngokuthi i-recarburizer ukukhulisa ngempumelelo okuqukethwe kwekhabhoni ensimbi encibilikisiwe ngemuva kokwengeza, ngakho-ke okuqukethwe kwekhabhoni engaguquki ye-recarburizer akumele kube phansi kakhulu, ngaphandle kwalokho ukufeza okuqukethwe okuthile kwekhabhoni, kuyadingeka ukwengeza ikhabhoni ephezulu kakhulu. okuqukethwe.Amasampula engeziwe we-recarburizer ngokungangabazeki azokhuphula inani lezinye izinto ezingezinhle ku-recarburizer, ukuze insimbi encibilikisiwe ingakwazi ukuthola izinzuzo ezingcono.
I-sulphur ephansi, izakhi ze-nitrogen ne-hydrogen ziyisihluthulelo sokuvimbela izimbotshana ze-nitrogen ekubunjweni, ngakho-ke ukwehla kokuqukethwe kwe-nitrogen ye-recarburizer, kungcono.Ezinye izinkomba ze-recarburizer, njengomswakama, umlotha, nezinto eziguquguqukayo, lapho inani lekhabhoni egxilile liyancipha, inani lekhabhoni engaguquki liphakeme, ngakho-ke lapho inani lekhabhoni engaguquki liphezulu, okuqukethwe kwalezi zingxenye eziyingozi akufanele kube ngaphezulu. phezulu.
Ngokwezindlela ezahlukahlukene zokuncibilikisa, izinhlobo zezithando zomlilo nosayizi bezithando zokuncibilikisa, kubaluleke kakhulu futhi ukukhetha usayizi wezinhlayiyana ezifanele ze-recarburizer, ezingathuthukisa ngempumelelo izinga lokumunca kanye nezinga lokumuncwa kwensimbi encibilikisiwe ku-recarburizer, futhi ugweme inkinga yobukhulu bezinhlayiyana ezincane kakhulu.Kubangelwa ukushiswa kwe-oxidative kwama-recarburizers.
Usayizi wezinhlayiyana zawo kungcono kakhulu: isithando somlilo esingu-100kg esingaphansi kuka-10mm, isithando somlilo esingu-500kg esingaphansi kuka-15mm, isithando somlilo esingamathani angu-1.5 esingaphansi kuka-20mm, isithando somlilo esingamathani angu-20 esingaphansi kuka-30mm.Ekuncibilikiseni isiguquli, lapho kusetshenziswa insimbi enekhabhoni ephezulu, kusetshenziswa i-recarburizer enokungcola okumbalwa.Izidingo zama-recarburizers okwenziwa kwensimbi okupheshulwa phezulu yikhabhoni engaguquki ephezulu, umlotha ophansi, oguquguqukayo nesibabule, i-phosphorus, i-nitrogen nokunye ukungcola, usayizi wezinhlayiyana owomile, ohlanzekile, nomaphakathi.Ikhabhoni yayo ehleliwe C ≥ 96%, indaba eguquguqukayo ≤ 1.0%, S ≤ 0.5%, umswakama ≤ 0.5%, usayizi wezinhlayiyana 1-5mm.Uma usayizi wezinhlayiyana muhle kakhulu, kulula ukuwushisa, futhi uma umaholoholo, untanta phezu kwensimbi encibilikisiwe futhi awumuncwa kalula yinsimbi encibilikisiwe.Ezikolweni zokungeniswa, usayizi wezinhlayiyana ungu-0.2-6mm, okuyinsimbi nezinye izinhlayiya zegolide ezimnyama zingu-1.4-9.5mm, insimbi ye-carbon ephezulu idinga i-nitrogen ephansi, nosayizi wezinhlayiyana ngu-0.5-5mm, njll. Izidingo ezithile zisekelwe uhlobo oluthile lwesithando somlilo ukuncibilikisa ucezu lokusebenza Izinhlobo neminye imininingwane yokwahlulela nokukhetha okuqondile.
