Ngotshintsho oluqhubekayo kwintsimi yemizi-mveliso ye-ripples, i-DC yokunyibilikisa iziko kunye neenzuzo zayo ezizodwa kunye nethemba elibanzi lophuhliso, ngokuthe ngcembe ivela njengenkwenkwezi eqaqambileyo ukukhokela inkqubela phambili yobugcisa boshishino.
Okwangoku kushishino metallurgical isicelo DC izimbiwa ubushushu eziko ukususela 1970 waqala ukuphuhlisa iteknoloji entsha. Uzinzo lwe-arc yomlilo we-DC, ugxininiso lwamandla, ukusebenza kakuhle kwe-thermal, kunye nokusetyenziswa kwamandla aphantsi, ukusetyenziswa kwe-electrode encinci, ingxolo ephantsi yokusebenza, imveliso ephezulu.
Ngaphandle, ngo-1984 eMzantsi Afrika iye yakha umthamo 40MVA high carbon ferrochrome eziko ngqo langoku. China 70-80 iminyaka 1800-8000kvA ferrosilicon, lesilicon yoshishino, silicomanganese, ferrochrome, unyango inkunkuma eqinileyo DC izimbiwa ubushushu eziko (i-electrode enye ezantsi) kunye DC steelmaking eziko iphumelele amava athile ayimpumelelo, kwiminyaka yakutshanje, China iye yakhiwe kwaye yafakwa kwi. imveliso DC eziko ikakhulu:
12500-33000kvA Silicon-Manganese DC Mineral Heat Furnace(4 electrode)
I-12500-16500kvA iSilicon ePhakamileyo ye-DC yeMinerali yoBufudumezi beMinera (ii-electrode ezi-4)
I-12500kvA iSilicon Barium DC Iziko lobushushu leMinerali (ii-electrode ezi-4)
12500kvA iSilicon Zirconium DC Iziko lobushushu leMinerali(ii-electrode ezi-4)
10000-16000kw Industrial Silicon DC Mineral Heat Furnace(4 electrode)
9000kw Ferrochrome DC Mineral Heat Furnace(4 electrode)
I-30000kw i-Titanium Slag DC yeMineral Heat Furnace(isiseko se-electrode)
Uphuhliso lweziko lokunyibilikisa lwe-DC lumele ukutsibela phambili okukhulu kwinkqubela phambili yobuchwepheshe. Xa kuthelekiswa nesithando somlilo seminerali ye-AC yemveli, iingenelo zayo ziyabonakala. Ngokumalunga nokusebenza kakuhle kwamandla, isithando sokunyibilikisa i-DC siya kuguqulwa sibe ngamandla obushushu aphuculwe kakhulu. Amanani okwenene abonisa ukuba izinga lokusetyenziswa kwamandla limalunga ne-20% ephezulu kuneziko lemveli, elinciphisa kakhulu ilahleko yamandla kwaye lifake impembelelo enamandla yokunciphisa iindleko zemveliso kunye nokuphucula ukusebenza kakuhle kwezoqoqosho. Kwangaxeshanye, i DC izimbiwa ubushushu eziko ubonisa uzinzo ebalaseleyo kunye nokulawulwa ngexesha lokusebenza, kwaye uyakwazi ukulawula ngokuchanekileyo iimeko zokusabela eziko, ngaloo ndlela ukuqinisekisa uphuculo oluzinzileyo kumgangatho wemveliso kunye nokwanda okuthe chu kwimveliso.
Ngokutsho kwedatha ekhoyo, uthelekiso olubanzi lwezalathi zemveliso yeDC kunye nesithando somlilo se-AC, imveliso yesithando somlilo se-DC, ukusetyenziswa kwamandla kunye nezinye izikhombisi zingcono kakhulu kuneziko le-AC, ukwanda kwemveliso kungenxa yokunciphisa ukusetyenziswa kwamandla okunyibilikisa. kunye nokuphuculwa kwamandla ombane wesiphumo esidibeneyo seziphumo.
Okwangoku DC eziko 4 electrode, 6 electrode kunye nezinye uphuhliso lobuchwepheshe multi-electrode, ngakumbi ebonisa iingenelo ezicacileyo DC izimbiwa eziko ukunyibilikisa ferroalloys, yindlela engenakuphepheka yokonga amandla kunye ezinkulu-scale izimbiwa eziko. Ukongeza, ukudityaniswa kobuchwephesha obukrelekrele kwenza ukuba i-DC yokunyibilikisa idigri ye-automation ye-automation iphuculwe kakhulu, ukusebenza kulula ngakumbi kwaye kusebenza kakuhle, kuba imveliso yeshishini izise lula kakhulu.
Ngaxeshanye ingqikelelo yokhuselo lokusingqongileyo olunzulu, DC ukunyibilika eziko kwakhona ngenkuthalo ukwamkela trend eluhlaza amaxesha. Idatha efanelekileyo ibonisa ukuba i-DC yokunyibilika komlilo ekugcinweni kwamandla kunye nokusebenza kokunciphisa ukukhutshwa kuhle kakhulu, ukukhutshwa kongcoliseko kuncitshiswe kakhulu, kuba uphuhliso oluzinzileyo lube negalelo kumandla.
Ukuphonononga imbali yophuhliso lwe-DC yokunyibilika kwesithando somlilo, asinakuzibamba kodwa simangaliswe ngumsebenzi onzima kunye nobulumko obukhazimlisiweyo babaphandi kunye neenjineli. Ukusuka kwintsholongwane yengqikelelo yokuqala, ukuya kuphuculo oluqhubekayo kunye nokwenza ngcono itekhnoloji, inyathelo ngalinye lokubila kunye nobulumko babo. Umzekelo, xa uphuhlisa isithando sokunyibilikisa i-DC, ishishini liye laphucula ngempumelelo iiparamitha zombane kunye nezixhobo zesithando somlilo kunye nolwakhiwo emva kovavanyo oluninzi kunye nophuculo, ukuze umzimba wesithando somlilo ukwazi ukumelana neemeko ezinzima ezifana nobushushu obuphezulu kunye noxinzelelo oluphezulu. ngexesha elifanayo, ukusebenza kwee-electrode kunye nezinye izinto eziphambili ziye zaphuculwa kakhulu.
Ukujonga phambili, isithando somlilo seminerali ye-DC kulindeleke ukuba sifezekise impumelelo enkulu kunye nophuhliso:
Okokuqala, iteknoloji entsha iya kukhuthaza ukusebenza kakuhle kwamandla kunye nokuzinza kwe-DC yokunyibilika komlilo ukuze kuphuculwe ngakumbi, kuncede amashishini ukunciphisa iindleko zemveliso kunye nokuphucula ukukhuphisana kwimarike.
Okwesibini, uphuhliso lweziko lokufudumeza izimbiwa ze-DC luya kuthatha ithuba lobukrelekrele bokwenziwa, idatha enkulu kunye nezinye iindlela zobuchwepheshe ezikrelekrele ukuqonda ukubekwa kweliso kwexesha lokwenyani kunye nokulawulwa ngokuzenzekelayo kweemeko zokunyibilika kweziko, ukukhawulezisa ukusetyenziswa kwezixhobo ezincedisayo ezikrelekrele, kubandakanya i-AI ekrelekrele. ukucokisa, iplagi yamehlo evulekileyo yerobhothi, irobhothi yokudibanisa i-electrode, umatshini wokungqungqa ozenzekelayo, irobhothi yokuhlola, isixhobo sokucinga sobushushu obuphezulu eziko, isixhobo sokucoca ngokuzenzekelayo, inkqubo yokuphosa eqhubekayo, kunye nezinye izixhobo ezincedisayo eziphucukileyo, ukuze kuphuculwe ukusebenza kakuhle kwemveliso, ukunciphisa amandla. ukusetyenziswa, ukuphucula umgangatho wemveliso, kwaye baqonde ubukrelekrele kunye nohlaza inkqubo yemveliso.
Ukongeza, imimandla yesicelo se-DC yokunyibilikisa isithando somlilo nayo iya kwandiswa, ngaphezu kokudlala indima ebalulekileyo kwishishini lesinyithi, kulindeleke ukuba isetyenziswe ngokubanzi kushishino lweekhemikhali, izixhobo kunye nezinye iindawo, ezinegalelo kwinkqubela phambili kunye nophuhliso. yamashishini amaninzi.
Ukusetyenziswa okuyimpumelelo kwe-DC kwiziko lobushushu beminerali kuzise inzuzo ebalulekileyo kunye namathuba ophuhliso kwishishini lokunyibilikisa. Ngokusebenzisa uhlaziyo oluqhubekayo kunye nenkqubela phambili yezobuchwepheshe, sinesizathu sokukholelwa ukuba i-DC iya kuqhubeka idlala indima ebalulekileyo kwixesha elizayo, ukukhuthaza uphuhliso oluqhubekayo kunye nenkqubela phambili yetheknoloji yokushisa izimbiwa, ukunyibilikisa itekhnoloji yokuphucula kunye nokubonelela ngesithuba esingenamkhawulo sophuhliso. yeemveliso ezintsha, ukuze icandelo lemizi-mveliso lizise imbonakalo ebanzi kunye nophuhliso oluzinzileyo lwekamva.
Ngamafutshane, i-DC yezimbiwa eziko lobushushu kunye neenzuzo zayo ezizodwa kunye nethemba elibanzi lophuhliso, iya kuqhubeka idlala indima ebalulekileyo kwintsimi yezoshishino yexesha elizayo, kwaye yenza igalelo elikhulu kwinkqubela yoshishino kunye nophuhliso oluzinzileyo. Sijonge phambili kwizinto ezintsha kunye neempumelelo zokukhuthaza iteknoloji yesithando somlilo seminerali ye-DC ukuya kwincopho entsha!
