I-Recarburizerukwenza insimbi nge-recarburizer (izinga lemboni ye-ferrous metallurgy ye-People's Republic of China, YB/T 192-2001 steelmaking nge-recarburizer) kanye nensimbi ephonswe nge-recarburizer, nezinye izinto ezingeziwe nazo ziwusizo ekubuyiseleni kabusha, njenge-brake pad enezithasiselo, njengezinto zokungqubuzana.I-Recarburizer ingeyokwenziwa kwensimbi yangaphandle, insimbi yokwenza kabusha i-recarburizer izinto ezingavuthiwe.I-recarburizer yekhwalithi ephezulu iyisengezo esiyisiza esibalulekile ekukhiqizeni insimbi yezinga eliphezulu.
Ukusetshenziswa kwe-carbon agent:
Enqubweni yokuncibilikisa, ngenxa yokunqwabelana okungalungile noma ukushaja kanye nokususwa kwe-carburization ngokweqile nezinye izizathu, ngezinye izikhathi okubangelwa okuqukethwe kwekhabhoni yensimbi akuzange kuhlangabezane nezidingo zenkathi ephakeme kakhulu, bese kuba yi-carburization yensimbi ewuketshezi.I-carburizing agent evame ukusetshenziswa kakhulu i-carburizing iron yengulube, i-electrode impushana, i-petroleum coke powder, i-charcoal powder kanye ne-coke powder.Isiguquli esincibilikisayo esiphakathi nendawo kanye nensimbi yensimbi ephezulu, ukusetshenziswa kwe-petroleum coke equkethe ukungcola okumbalwa njenge-carburizing agent.Izidingo ze-recarburizer yokwenza insimbi yokuguquguquka evuthwe phezulu yikhabhoni engaguquki ephezulu, okuqukethwe komlotha okuphansi. , i-volatile, isulfure, i-phosphorus, i-nitrogen nokunye ukungcola, okomile, kuhlanzekile, nosayizi wezinhlayiyana ophakathi.
Iqembu le-carbon engaguquki lihlukaniswe laba:
w(C)>96%, izinto eziguquguqukayo ≤1.0%, W (S)≤0.5%, W (umswakama)≤0.55%, usayizi wezinhlayiyana we-1 kuya ku-5mm.
Uma usayizi wezinhlayiyana muhle kakhulu, kulula ukuwushisa.Uma imaholoholo, intanta phezu kwensimbi encibilikisiwe futhi akulula ukumuncwa insimbi encibilikisiwe.Ngosayizi wezinhlayiyana zesithando sokungenisa ngaphakathi ku-0.2-6mm, insimbi nobunye usayizi wezinhlayiya zensimbi ezimnyama ku-1.4-9.5mm , i-carbon steel high idinga i-nitrogen ephansi, usayizi wezinhlayiyana ku-0.5-5mm, njalonjalo ngesidingo esithile ngokusho kohlobo oluthile lokuncibilikisa isithando somlilo nokunye imininingwane yokwahlulela nokukhetha okuqondile.
1, indlela yokufaka isithando somlilo:
I-Recarburizer ifanele ukuncibilika esithandweni sokungeniswa, kodwa ukusetshenziswa okuqondile akufani ngokuya ngezidingo zenqubo.
(1) ukusetshenziswa kwe-recarburizer ekuncibilikiseni isithando somlilo kagesi, ngokwesilinganiso noma izidingo ezilingana nekhabhoni nezinto ezingezwe engxenyeni engezansi yesithando somlilo kagesi, izinga lokubuyisela lingafinyelela ngaphezu kwama-95%;
(2) uma ukuntuleka kokulungiswa kwe-carbon, i-slag yokuqala yesithando somlilo weshumi nambili, kanye ne-carburant, ngokukhuphula izinga lokushisa lensimbi encibilikisiwe, noma i-electromagnetic enyakazayo ukuze kuncibilike ukumuncwa kwekhabhoni, izinga lokubuyisela licishe libe ngu-90%, uma izinga lokushisa liphansi. Inqubo ye-carbonization, ukuncibilika kwesithando somlilo ingxenye kuphela yoketshezi lwensimbi encibilikisiwe ngaphansi kwesimo sokushisa okuphansi, yonke i-recarburizer ngesikhathi esisodwa kuyinsimbi ewuketshezi, ngasikhathi sinye, icindezelwa ensimbi encibilikisiwe ngeshaja eqinile ukuze ingangeni. veza ubuso bensimbi encibilikisiwe.Ngale ndlela, i-carburization yensimbi ewuketshezi ingafinyelela ngaphezu kwe-1.0%.
2, ngaphandle kwe-carburizing yomlilo:
(1) fafaza impushana yegraphite esikhwameni
Ukusebenzisa i-graphite powder njenge-recarburizer, umthamo womjovo ungu-40kg/t, kanti okuqukethwe kwekhabhoni yensimbi enguketshezi kulindeleke ukuthi kwenyuke kusuka ku-2% kuye ku-3%. Izinga lokushisa lensimbi encibilikisiwe ngaphambi kokufakwa kwe-carburization lalingu-1600 ℃, futhi izinga lokushisa elijwayelekile ngemva kokufakwa kwe-carburization laliyi-1600 ℃. I-1299 ℃.I-Jet graphite powder carburization, ngokuvamile isebenzisa i-nitrogen njengesithwali, kodwa ngaphansi kwezimo zokukhiqiza zezimboni, ngomoya ocindezelweyo ungcono kakhulu, futhi ukushiswa komoya-mpilo emoyeni ocindezelwe ukukhiqiza i-CO, ukushisa kwamakhemikhali kungabuyisela ingxenye yokwehla kwezinga lokushisa, kanye ne-CO enciphisa umoya ukuze kuthuthukiswe umphumela we-carburization.
(2) ukusetshenziswa kwe-recarburizer lapho insimbi
Izinjongo eziyi-100-300 ze-graphite powder carburizer zingafakwa esikhwameni, noma ethangini lensimbi ngokugeleza, emva kokuba uketshezi lwensimbi lunyakazeke ngokugcwele, ngangokunokwenzeka ukuncibilikisa ukumuncwa kwekhabhoni, izinga lokubuyisa ikhabhoni licishe libe ngama-50% .
Isetshenziselwa cast, cast iron, cast steel, cast kuyoba nemfuneko carbon, carburant njengoba nje negama layo lisikisela ukwandisa okuqukethwe carbon in liquid iron, futhi, isibonelo, evame ukusetshenziswa in smelting isithando charge for pig iron, Scrap. insimbi, ibuyele eshajelweni yesithando somlilo, okuqukethwe kwekhabhoni yensimbi kuphezulu, kodwa inani lokuthenga okulahliwe liphakeme kakhulu, ngakho-ke khulisa ukunikezwa kwezilahlwa, unciphise inani lensimbi ecijile, Ukwengezwa kwe-recarburizer kunganciphisa izindleko zokuphonsa ngezinga elithile.
