Ukusetshenziswa kwe-Recarburizer

1. Indlela yokufaka isithando somlilo:

I-Recarburizer ifanele ukuncibilika esithandweni sokungeniswa, kodwa ukusetshenziswa okuqondile akufani ngokuya ngezidingo zenqubo.
(1) Ukusetshenziswa kwe-recarburizer esithandweni somlilo esincibilikisa imvamisa emaphakathi kungangezwa ezingxenyeni ezimaphakathi neziphansi zesithando somlilo ngokwesilinganiso noma izidingo ezilingana nekhabhoni, futhi izinga lokubuyisela lingafinyelela ngaphezu kwama-95%;
(2) Insimbi encibilikisiwe uma inani lekhabhoni linganele ukulungisa isikhathi sekhabhoni, qala uhlanze i-slag encibilikisiwe esithandweni, bese wengeza i-recarburizer, ngokusebenzisa ukushisa kwensimbi okuwuketshezi, ukunyakazisa kazibuthe noma ukuvuselela okwenziwa ukuncibilikisa ukumuncwa kwekhabhoni, izinga lokutakula lingaba cishe ngama-90, uma inqubo ye-carburizing yokushisa ephansi, okungukuthi, inkokhiso incibilika ingxenye yokushisa kwensimbi encibilikisiwe iphansi, yonke i-ejenti ye-carburizing yengezwa ensimbi ewuketshezi ngesikhathi esisodwa.Ngesikhathi esifanayo, icindezelwa oketshezini lwensimbi ngokushaja okuqinile ukuyigcina ingavezi uketshezi lwensimbi.I-carburization ye-iron liquid kule ndlela ingafinyelela ngaphezu kwe-1.0%.

2. Ngaphandle kwesithando somlilo:

(1) Iphakethe lifuthwa nge-graphite powder, i-graphite powder isetshenziswa njenge-recarburizer, kanti inani elipheshulwayo lingu-40kg/t, okulindeleke ukuthi likhulise okuqukethwe kwekhabhoni yensimbi ewuketshezi lisuka ku-2% liye ku-3%.Njengoba okuqukethwe kwekhabhoni yensimbi enguketshezi kwanda kancane kancane, izinga lokusebenzisa ikhabhoni lehla.Izinga lokushisa lensimbi ewuketshezi ngaphambi kwe-carburization laliyi-1600 ℃, futhi izinga lokushisa elijwayelekile ngemuva kwe-carburization laliyi-1299 ℃.I-graphite powder carburization, ngokuvamile isebenzisa i-nitrogen njengesithwali, kodwa ezimweni zokukhiqiza ezimbonini, umoya ocindezelweyo ungcono kakhulu, futhi umoya-mpilo ekushiseni komoya ocindezelwe ukukhiqiza i-CO, ukushisa kwamakhemikhali okusabela kunganxephezela ingxenye yokwehla kwezinga lokushisa, kanye nokunciphisa kwe-CO. Umkhathi uvumela ukuthuthukisa umphumela we-carburization.
(2) Ukusetshenziswa kwe-recarburizer lapho insimbi, ingaba yi-100-300mesh graphite powder recarburizer ephaketheni, noma isuka emkhombeni wensimbi ngokugeleza, ngemva kokuba uketshezi lwensimbi lunyakaziswa ngokugcwele, ngangokunokwenzeka ukuncibilikisa ukumuncwa kwekhabhoni, ikhabhoni. izinga lokuthola kabusha elingaba ngu-50%.
