Electrode yeGraphite chikamu chakakosha cheEAFsteelmaking, asi inongotarisa chikamu chidiki chemutengo wekugadzira simbi. Zvinotora 2 kg ye graphite electrode kugadzira tani yesimbi.
Sei uchishandisa ma electrode e graphite?
Electrode yeGraphite ndiyo inonyanya kushandisa simbi yekupisa muchoto chearc. EAFs inyanzvi yekunyungudutsa tsvina kubva mumotokari dzekare kana midziyo yemumba kuti igadzire simbi itsva.
Mari yekuvaka chigadziko chemagetsi che arc furnace yakaderera pane yepurasitiki yechinyakare. Machira epurasitiki echinyakare anogadzira simbi kubva musimbi uye anoshandisa marasha ekubikisa semafuta. Zvisinei, mutengo wekugadzira simbi wakakwira uye kusvibiswa kwezvakatipoteredza kwakakomba. Zvisinei, EAF INOSHANDISA simbi dzakasara nemagetsi, izvo zvisingakanganisi nharaunda zvakanyanya.
Electrode yegrafiti inoshandiswa kuunganidza electrode nechifukidziro chechoto kuti zvive zvese, uye electrode yegrafiti inogona kushandiswa kumusoro nekudzika. Mvura inozopfuura nemu electrode, ichigadzira arc inodziya zvakanyanya inonyungudutsa simbi yakapwanyika. Electrodes anogona kusvika 800mm (2.5ft) mudhayamita uye kusvika 2800mm (9ft) muhurefu. Huremu hwepamusoro hunopfuura matani maviri.
Kushandiswa kwe graphite electrode
Zvinotora makirogiramu maviri (4.4 pounds) ema graphite electrodes kuti pagadzirwe tani yesimbi.
Tembiricha ye graphite electrode
Musoro we electrode uchasvika 3,000 degrees Celsius, hafu yekupisa kwezuva pamusoro. Electrode yakagadzirwa ne graphite, nekuti graphite chete ndiyo inogona kutsungirira kupisa kwakanyanya kudaro.
Wobva watenderedza chitofu parutivi rwacho wodurura simbi yakanyungudutswa mumadhiramu makuru. Chirongo chacho chinozoendesa simbi yakanyungudutswa kuchinhu chinogadzirwa nesimbi, icho chinoshandura marara akadzokororwa kuita chigadzirwa chitsva.
Electrode yeGraphite inoshandisa magetsi
Maitiro aya anoda magetsi akakwana kuti ape simba muguta rine vanhu 100,000. Muchoto chemagetsi chemazuva ano, kunyunguduka kwega kwega kunowanzotora maminetsi makumi mapfumbamwe uye kunogona kugadzira matani zana nemakumi mashanu esimbi, zvakakwana kugadzira mota zana nemakumi maviri nemashanu.
Zvinhu zvisina kugadzirwa
Needle coke ndiyo inonyanya kushandiswa pakugadzira ma electrodes, ayo anotora kusvika mwedzi mitatu kusvika mitanhatu kuti agadziriswe. Maitiro aya anosanganisira kugocha nekuisazve mudumbu kuti coke ishandurwe kuita graphite, akadaro mugadziri.
Kune ma "needle coke" anoshandiswa mupetroleum uye "needle coke" anoshandiswa mumarasha, ese ari maviri anogona kushandiswa kugadzira ma "graphite electrodes". "Pet coke" inongobva mu "petroleum refine", nepo "coal-to-coke" inogadzirwa ne "coal tar" inoitika panguva yekugadzira coke.
