Iyini i-carburant?

Kunezinhlobo eziningi ze-carburizers, kufaka phakathi amalahle, i-graphite yemvelo, i-graphite yokwenziwa, i-coke nezinye izinto ezisetshenziswayo.Izinkomba ezibonakalayo zokuphenya nokulinganisa ama-carburizer ikakhulukazi indawo yokuncibilika, isivinini sokuncibilika, nendawo yokuthungela.Izinkomba zamakhemikhali eziyinhloko okuqukethwe kwe-Carbon, okuqukethwe kwesibabule, okuqukethwe kwe-nitrogen, nokuqukethwe kwe-hydrogen.Isibabule ne-hydrogen yizakhi eziyingozi.Ebangeni elithile, i-nitrogen iyisici esifanele.Ekukhiqizeni i-synthetic cast iron, i-carburizer enekhwalithi engcono kuthiwa Okubaluleke kakhulu i-graphitized recarburizer, ngoba ngaphansi kwezimo zokushisa okuphezulu, ama-athomu e-carbon ahlelwa ngendlela encane ye-graphite, ngakho-ke ibizwa ngokuthi i-graphitization.Ama-carburizers angakhuphula kakhulu inani lezinsimbi ezilahliwe ezisetshenziswa ekubunjweni, futhi abone ukusetshenziswa kwensimbi yengulube encane noma engekho.

Umsebenzi we-Carburizer:
I-Carburizer iyimpahla yokusetshenziswa ebalulekile yokuncibilikisa insimbi encibilikisiwe esithandweni sokungeniswa, futhi ikhwalithi yayo nokusetshenziswa kwayo kuthinta ngqo ikhwalithi yensimbi encibilikisiwe.Ama-castings anezidingo ezithile zekhabhoni, ngakho-ke ama-carburizer asetshenziswa ukukhulisa okuqukethwe kwekhabhoni kunsimbi encibilikisiwe.Izinto ezisetshenziswa kakhulu eziko ekuncibilikiseni i-pig iron, scrap steel, nezinto ezigaywe kabusha.Nakuba okuqukethwe kwekhabhoni yensimbi yengulube kuphezulu, izindleko ziphakeme kakhulu kunezinsimbi ezilahliwe.Ngakho-ke, ukusetshenziswa kwe-recarburizer kungakhuphula inani lensimbi yensimbi futhi kunciphise inani lensimbi yengulube, ukuze kuncishiswe izindleko zokuphonsa.
Izigaba ze-carburizers:
I-graphite recarburizer isho ukuguqulwa kwesakhiwo samangqamuzana emikhiqizo yekhabhoni ngokusebenzisa izinga lokushisa eliphezulu noma ezinye izindlela, futhi kukhona ukuhlelwa okuvamile.Kulolu hlelo lwama-molecular, ibanga le-molecular of carbon libanzi, elivumela ukubola nokwakheka kunsimbi encibilikisiwe noma insimbi.zenuzi.Ama-graphite recarburizer okwamanje asemakethe ngokuvamile avela ezindleleni ezimbili, eyodwa ukusika imfucuza yama-electrode e-graphite, kanti enye iwumkhiqizo we-graphitization we-petroleum coke emazingeni angama-3000.

I-carburizer esekwe emalahleni ingumkhiqizo obalwa ngaphansi kwezimo zokushisa okuphezulu kusetshenziswa i-anthracite njengempahla eluhlaza.Inezici zokuqukethwe okuphezulu kwekhabhoni engaguquki, ukumelana ne-oxidation eqinile nokuqukethwe okuphansi kwezinto eziyingozi.Ingasetshenziswa njenge-ejenti yokunciphisa inqubo yokuncibilikisa.Ngesikhathi senqubo yokwenza insimbi yesithando somlilo se-arc, i-coke noma i-anthracite ingangezwa njenge-carburizer lapho ishaja.
