Ukusetshenziswa kwama-recarburizers ahlukahlukene
I-Carburizer iyinto yamakhemikhali engathuthukisa ngempumelelo umphumela we-carbonization wezinto zokwakha kanye nemvelo ye-metallurgical.Kunama-carburizer amaningi asetshenziswa embonini yensimbi neyensimbi.Ama-recarburizer ahlukene ngezinjongo ezahlukene anemiphumela ehlukene.
1. I-graphite recarburizer yokwenziwa
I-raw material eyinhloko ye-graphite yokwenziwa i-powder calcined petroleum coke, lapho i-pitch (noma i-pregelatinization ehlanzekile ye-organic) yengezwa njenge-binder, bese kunezelwa inani elincane lezinye izinto ezisizayo.Ngezinto ezihlukahlukene zokusetshenziswa, iyacindezelwa futhi yakhiwe, bese icutshungulwa endaweni engafaki i-oxidizing ku-2500-3000 ° C ukuze yenziwe i-graphitized.Ngemuva kokwelashwa kokushisa okuphezulu, okuqukethwe komlotha, isulfure negesi kuyancipha kakhulu.
Ngenxa yenani eliphezulu lemikhiqizo ye-graphite yokwenziwa, iningi lama-graphite recarburizers asetshenziswa kakhulu lisebenzisa izinto ezigaywe kabusha njengama-chips, ama-electrodes alahlwayo namabhulokhi e-graphite lapho kukhiqizwa ama-electrode egraphite ezindaweni ezisunguliwe ukuze kwehliswe izindleko zokukhiqiza.Lapho kuncibilika i-iron ductile, ukuze ikhwalithi ye-metallurgical ye-cast iron ibe phezulu, i-recarburizer kufanele ibe yi-graphite yokwenziwa.
Ukusetshenziswa kwe-graphite recarburizer: I-graphite recarburizer ingathuthukisa ukwakheka kwe-metallographic of castings, ikhiqize ngokushesha umgogodla we-graphite kunsimbi ecijile, ifinyeze isikhathi se-carbonization, futhi ithuthukise umphumela we-carbonization.
2. I-petroleum coke recarburizer
I-petroleum coke iyi-recarburizer esetshenziswa kabanzi, futhi i-petroleum coke iwumkhiqizo wokucwenga uwoyela ongahluziwe.Uwoyela osele kanye ne-petroleum pitch etholwe ngokufakwa kwe-pressurized noma i-vacuum distillation ingasetshenziswa njengezinto zokusetshenziswa zokwenziwa kwe-petroleum coke, futhi i-petroleum coke ingatholakala ngemva kokupheka.Ukukhishwa kwe-petroleum coke eluhlaza kungaphansi kwenani likawoyela ongahluziwe, futhi okuqukethwe okungcolile kwe-petroleum coke eluhlaza kuphezulu, ngakho ngeke kusetshenziswe ngokuqondile njenge-carburizer futhi kufanele kubalwe kuqala.I-petroleum coke eluhlaza inezipontshi, inaliti, i-granular kanye nezimo eziwuketshezi.
Ukusetshenziswa kwe-petroleum coke recarburizer: I-petroleum coke recarburizer ingakhuphula ngempumelelo izinga lokushisa lesithando, ayikwazi nje ukwandisa izinga lokushisa lomlilo, kodwa futhi ithuthukise isivuno se-metallurgical, ithuthukise futhi ithuthukise imvelo enokhahlo ye-metallurgical.
3. I-Coke ne-Anthracite
Enqubweni yokwenza insimbi ye-arc yomlilo kagesi, i-coke noma i-anthracite ingangezwa njenge-recarburizer.Insimbi encibilikisiwe yesithando somlilo esincibilikisayo ayivamisile ukusetshenziswa njenge-recarburizer ngenxa yomlotha wayo omningi nokuqukethwe okuguquguqukayo.I-calciner ibalwa nge-anthracite, futhi izinga lokushisa lokubala liyi-1200-1300.I-granular emnyama, i-metallic luster, i-fixed carbon 85-93, isulfure emaphakathi kanye nokuqukethwe kwe-nitrogen.
Ukusetshenziswa kwe-calcined coal recarburizer: Inhloso ye-calcined coal recarburizer ukukhulisa ngempumelelo ikhabhoni kanye nokunciphisa isikhathi se-carbonization.Ukusetshenziswa kwe-calcined coal recarburizer kungonga isikhathi ngempumelelo.
