Indlela yokunciphisa ukusetshenziswa kwama-electrode
Eminyakeni yamuva nje, ngokuthuthukiswa okunamandla kwemboni yensimbi yesithando somlilo waseChina, kanye nezidingo zochwepheshe bokonga nokunciphisa ukusetshenziswa kwamandla kanye nezazi ekhaya nakwamanye amazwe baphetha ezinye zezindlela eziphumelelayo kanje:
I-1.I-anti-oxidation mechanism ye-spray yamanzi i-graphite electrode
Ngocwaningo lokuhlola, ukufafaza isixazululo se-anti-oxidation ebusweni bama-electrode sekufakazele ukuthi kungcono kakhulu uma umiswa kusuka ku-oxidation eseceleni ye-graphite electrode, futhi amandla e-anti-oxidation anda izikhathi ezi-6-7. Ngemuva kokusebenzisa le ndlela, ukusetshenziswa kwe-electrode kwehle kwafinyelela ku-1.9-2.2kg ukuncibilikisa ithani lensimbi.
2.I-electrode engenalutho
Eminyakeni yamuva, iNtshonalanga Yurophu neSweden aqale ukusebenzisa ama-electrode angenalutho ekukhiqizeni iziko lensimbi ye-ferroalloy. Ama-electrode angenalutho, umumo wesilinda, ngokuvamile awanalutho ngaphakathi avalwe ngegesi engasebenzi. Ngenxa yokungabi nalutho, izimo zokubhaka ziba ngcono futhi zenze amandla e-electrode abe phezulu. Ngokuvamile, ingonga ama-electrode ngo-30% -40%, kuze kufike ku-50% kakhulu.
3.DC isithando somlilo
I-DC electric arc furnace iwuhlobo olusha lwesithando somlilo esincibilikisa i-arc esisanda kwakhiwa emhlabeni eminyakeni yamuva nje. Kusukela kudatha eshicilelwe phesheya, i-DC arc furnace ingenye yezindlela eziphumelela kakhulu zokunciphisa ukusetshenziswa kwama-electrode. Ngokuvamile, ukusetshenziswa kwama-electrode kungancishiswa cishe ngo-40% kuya ku-60%. Ngokwemibiko, ukusetshenziswa kwe-graphite electrode yesithando somlilo esinamandla amakhulu we-DC yehliswe kwaba ngu-1.6kg/t.
4.Electrode surface enamathela ubuchwepheshe
Ubuchwepheshe be-Electrode coating ubuchwepheshe obulula nobusebenzayo bokunciphisa ukusetshenziswa kwama-electrode, ngokuvamile bunganciphisa ukusetshenziswa kwama-electrode cishe ngama-20%. Izinto zokumboza ze-electrode ezivame ukusetshenziswa ziyi-aluminium kanye nezinto ezihlukahlukene zobumba, ezinokumelana ne-oxidation okuqinile emazingeni okushisa aphezulu futhi zinganciphisa ngempumelelo ukusetshenziswa kwe-oxidation yendawo eseceleni ye-electrode. Indlela yokugcoba i-electrode ngokuyinhloko ngokufafaza nokugaya, futhi inqubo yayo ilula futhi kulula ukuyisebenzisa. Kuyindlela evame ukusetshenziswa kakhulu yokuvikela ama-electrode.
5.I-electrode efakiwe
Gcoba ama-electrode esixazululweni samakhemikhali ukuze ubangele ukusebenzisana kwamakhemikhali phakathi kwendawo ye-electrode nama-ejenti ukuze kuthuthukiswe ukumelana kwe-electrode ku-oxidation yezinga lokushisa eliphezulu. Lolu hlobo lwama-electrode lunganciphisa ukusetshenziswa kwama-electrode cishe ngo-10% kuya ku-15%.
