Indlela yokunciphisa ukusetyenziswa kwe-electrode
Kwiminyaka yakutshanje, kunye nophuhliso olunamandla loshishino lwentsimbi yaseTshayina yombane, kunye neemfuno zokonga amandla kunye neengcali zokunciphisa ukusetyenziswa kunye nabaphengululi ekhaya nakwamanye amazwe baqukumbela ezinye iindlela ezisebenzayo ngolu hlobo lulandelayo:
1.I-Anti-oxidation mechanism of water spray graphite electrode
Ngophando lovavanyo, ukutshiza isisombululo se-anti-oxidation kumphezulu wee-electrode kubonakalise ngcono kakhulu ekumiseni ukusuka kwicala le-oxidation ye-graphite electrode, kwaye amandla okulwa ne-oxidation anyuka ngamaxesha angama-6-7.Emva kokusebenzisa le ndlela, ukusetyenziswa kwe-electrode kuye kwehla ukuya kwi-1.9-2.2kg yokunyibilikisa itoni yentsimbi.
2.I-electrode eHollow
Kwiminyaka yakutshanje, iNtshona Yurophu neSweden ziye zaqalisa ukusebenzisa i-electrode engenanto xa kuveliswa iziko lentsimbi ekrwada ye-ferroalloy.Ii-electrodes eziHollow, imilo yesilinda, zihlala zingenanto ngaphakathi zitywinwe ngegesi engasebenziyo.Ngenxa yobunzulu, iimeko zokubhaka ziyaphucuka kwaye zenze amandla e-electrode abe phezulu.Ngokuqhelekileyo, inokugcina i-electrodes ngama-30% -40%, ukuya kuma-50% kakhulu.
3.DC isithando somlilo
I-DC electric arc furnace luhlobo olutsha lwesithando sombane esinyibilikisayo esandula ukuphuhliswa kwihlabathi kwiminyaka yakutshanje.Ukusuka kwidatha epapashwe phesheya, i-DC arc furnace yenye yezona ndlela zisebenzayo zokunciphisa ukusetyenziswa kwe-electrode.Ngokuqhelekileyo, ukusetyenziswa kwe-electrode kungancitshiswa malunga ne-40% ukuya kwi-60%.Ngokweengxelo, ukusetyenziswa kwe-electrode yegraphite ye-DC enkulu ye-ultra-high power furnace yombane iye yancitshiswa yaba yi-1.6kg / t.
I-4.Ubuchwephesha bokugquma ubuso be-Electrode
Itekhnoloji yokwambathisa i-Electrode yitekhnoloji elula nesebenzayo yokunciphisa ukusetyenziswa kwe-electrode, ngokuqhelekileyo inokunciphisa ukusetyenziswa kwe-electrode malunga ne-20%.Izinto ezisetyenziswa ngokuqhelekileyo zokugquma i-electrode ziyi-aluminium kunye nezixhobo ezahlukeneyo ze-ceramic, ezinokumelana ne-oxidation eqinile kumaqondo aphezulu kwaye inokunciphisa ngokufanelekileyo ukusetyenziswa kwe-oxidation ye-electrode side surface.Indlela yokugcoba i-electrode ikakhulu ngokutshiza kunye nokugaya, kwaye inkqubo yayo ilula kwaye kulula ukuyisebenzisa.Yeyona ndlela isetyenziswa ngokuqhelekileyo yokukhusela i-electrode.
5.I-electrode efakwe ngaphakathi
Dip electrode kwisisombululo sekhemikhali ukubangela ukusebenzisana kweekhemikhali phakathi kwendawo ye-electrode kunye nee-arhente zokuphucula ukuxhathisa kwe-electrode kwi-oxidation ephezulu yobushushu.Olu hlobo lwee-electrode lunokunciphisa ukusetyenziswa kwe-electrode malunga ne-10% ukuya kwi-15%.
