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 eziphezulu, ama-athomu e-carbon ahlelwa ngendlela encane ye-graphite, ngakho 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, enye iwukusika imfucuza yama-electrode e-graphite, kanti enye ingumkhiqizo 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.
