Ukuhambahamba kweLizwe le-UHP ye-UHP ye-ENGRODS: Isikhokelo esibanzi se-STEEL SIRSINIS

Eli nqaku libonelela ngokunzulu kwihlabathi elinamandla e-Ultra-ephezulu (UHP) I-ECRADRESS ENGRODSE, izinto ezibalulekileyo kwi-Steelmaking yanamhlanje. Siza kuphonononga iipropathi zabo, izicelo, iinkqubo zokwenza imveliso, kunye nokuqwalaselwa okuphambili ekuthengweni kwempahla. Ukuba ubandakanyeka kwimveliso yentsimbi, izixhobo ze-ARC zombane (EAF), okanye ukuthengwa kweemveliso zegrafu, eli nqaku libalulekile ekufundeni okusebenzayo, ekusebenziseni umgca osebenza kakuhle wokusebenza kunye nomgca osezantsi wokusebenza. Ukusuka ekuqondeni amabakala ahlukeneyo okukhetha umthengisi ofanelekileyo, sikufihlile.

1. Ithini i-Uhp igraphite ye-EHPRODS kwaye kutheni zibalulekile?

I-UHP (Amandla e-Ultra-ephezulu) Ii-electrodes ze-encrodes zizinto ezifunekayo kwiziko lombane ze-ARC Baqhuba oombane obukhulu obufunekayo ukuze banyibilike inyibilikisi kunye nentsimbi ecocekileyo. Amandla abo okumelana nobushushu obukhulu, uxinzelelo lwangoku, kunye neengcambu zekhemikhali zenza ukuba babe nakho kwimveliso yentsimbi yanamhlanje. Uphawu oluphambili lwe-Uhp ye-Uhp i-electrodes kukungasebenzi kakuhle.

Ezi ze-electrodes zikhonaIsetyenziselwa ikakhuluKwi-Ultra-ephezulu yamandla e-Arc ye-Arc I-UHP ye-UHP ye-UHP yenziwa kwizinto eziphezulu eziphezulu, i-Petroleum Coke kwayeInaliti coke, phantsi kwenkqubo yenkqubo equka ukubhaka, ukunikezelwa kunye nokulungelelanisa imizobo. Le nkqubo ikhokelela kwiimvelisongei-thermal kunye noomatshiniIpropathi, ibaluleke kakhulu ekusebenzeni kakuhle nangokuthembekileyo. IukuxinanakwayeUkomelela kwamatshiniYiba negalelo kubomi benkonzo ende.

2. Ingaba ibanga le-IHP ye-elektrode ichaphazela njani intsebenzo yentsimbi?

IIbangayeigrafu electrodeImpembelelo kakhuluintsebenzoKwi-EAF. I-UHP ye-IHP ye-Eictrodes, emele iphezuluIbanga, Nika ukwenziwa kombane okuphezulu kunye nombane ophantsiukumelanaXa kuthelekiswa namandla aphezulu (i-HP) kunye namandla aqhelekileyo (RP) electrodes. Oku kuguqulela kumandla amakhulu okusebenza, ukunciphisa ukusetyenziswa kwe-electrode, ekugqibeleni, iindleko zemveliso ezisezantsi.

Ukukhetha ngokuchanekileyoIbanga, njengeI-UHP igrafu, kunjalochazekaUkukhupha izikoukusebenza kakuhle. NgaphezuluIbangaI-Electrode, ngelixa ekuqaleni ibiza kakhulu, inokukhokelela kwisongela ixesha elide lolondolozo ngenxa ye-wovan yayo kwaye iphuculweintsebenzoekufumaneni iindawo zokubulala iinsimbi. Ukhetho oluchanekileyo lunokunciphisa kwakhona i-Dowantime elinxulumene nokuqhawula ukoyikwa kwe-elektrode okanye ukunxiba kwangaphambili, ngaloo ndlela benyuka imveliso epheleleyo kwiintsimbiishishini.

3. Zeziphi izixhobo eziphambili zegrafiki ye-Uhp ye-EHPRODSODS?

Uhpigrafu electronikizikhonaisetyenzisiwe ngokubanzikwiziko le-ARC elinamandla e-ARC (i-imeyile) yokuvelisaIntsimbi esemgangathweni ephezulukwayealloyizitithi. Zikwasetyenziswa nakwimililo ye-ladle ukuyahlaziyamolonintsimbikwaye uhlengahlengise ubume bekhemikhali. Ngaphaya kokutsala, bafumana izicelo zokunyibilikisa ezinye izinyithi kunye neimvelisokwizinto ezingezizo ezingezizo.

Ngokukodwa,I-Uhp igraphite ye-Ocportrode isiceloIinkqubo zokufikelela kwiinkqubo ezifuna ubushushu obungaphezulu kakhulu kunye nolawulo oluchanekileyo, njengeUkuveliswa kwezinto ze-alloykunye neentsimbi ezikhethekileyo. Ukukwazi kwabo ukuphathaUkuxinana okwangokuNgaphezu kwe-25 A / CM² ibenza balungele ezi zicelo zifunwayo.

4. Ukuqonda inkqubo yokwenziwa kwemveliso ye-UHP ye-elektroniki.

Iukuvelisaye-UHPigrafu electronikiyinkqubo entsonkothileyo ebandakanya amanqanaba aliqela aphambili. Iqala ngokukhetha ngononopheloluhlazaizixhobo, ikakhuluI-Petroleum Cokekunye ne-coal tetch. Ezi zixhobo zixutywe, zenziwe zibe yimilo oyifunayo, kwayeibhakwekumaqondo obushushu aphezulu. Iimvelisoifakwe i-graphithiingono.

Ukulandela ukubhaka, i-electrodeUkungavavanywangepile yokuphucula kwaboukuxinananamandla. Inqanaba lokugqibela yigraphiction, apho i-electros ishushu kakhuluamaqondo obushushu aphezulu. Le nkqubo inika indawo yokugqibelaimvelisoNgombane wayo ophantsiukumelana, phezuluukuqhubela phambili kwe-thermal, kunye ne-oxidation elungileyoukumelana.

I-5. Uhp vs. hp vs. I-Information ye-Electrodes: Yintoni umahluko?

Umahluko ophambili phakathi kwe-UHP, HP, kwayeAmandla rhoqo igrafu electronikiUbuxoki kukoyisa kwabo ngombane kunye nokukwazi ukuphatha uxinzelelo lwangoku. I-UHP ye-IHP ye-Eictrodes iyonakala ephantsi kwaye inokumelana noxinzelelo lwangoku, lubenza balungele ezona zinto zifuna umsebenzi we-EAF. I-HP Electrode inike ibhalansi phakathi kokusebenza kunye neendleko, ngelixa i-rp electrodesIsetyenziselwa ikakhulukwizicelo eziphantsi.

Ukukhetha phakathi kwezi ntlobo kuxhomekeke kwicandelo elithileimfunekoye-EAF kunye nohlobo lweintsimbiukuveliswa.I-UHP igrafuI-electrodes lukhetho olukhethiweyo lweemveliso eziphezulu,Intsimbi esemgangathweni ephezuluimveliso.
