Sei ma electrode e graphite ane simba rakawanda achidhura zvakanyanya?

Mutengo wepamusoro wema electrodes e graphite ane simba rakawanda unobva pamutengo wepamusoro wezvinhu zvakagadzirwa, maitiro akaoma ekugadzira, zvakanakira kushanda, uye simba rekushandisa zvinhu. Ongororo yakadzama ndeiyi inotevera:

1. Mitengo Yakakwira Yezvinhu Zvisina Kugadzirwa
   Zvinhu zvikuru zvekushandisa ma electrode e graphite ane simba rakawanda i needle coke ne petroleum coke, ne needle coke iri chinhu chakakosha. Needle coke ine fibrous texture, low thermal expansion coefficient, uye nyore kushandisa graphitization, zvichiita kuti ive chinhu chakanakira kugadzira ma electrode e graphite ane simba rakawanda kana kuti ane simba rakawanda. Zvisinei, maitiro ayo ekugadzira akaomarara, ane zvipingamupinyi zvehunyanzvi, uye kuwanikwa kwepasi rose kunoramba kuripo, zvichikonzera mitengo yakakwira nguva dzose. Pamusoro pezvo, petroleum coke, chimwe chinhu chakakosha, chinokanganiswa nekuchinja kwemusika uye mitengo yemafuta asina kucheneswa, nemitengo iri kukwira mumakore achangopfuura. Kukwira uku kwemitengo yezvinhu zvisina kucheneswa kunokwidza zvakananga mari yekugadzira ma electrode e graphite ane simba rakawanda.

2. Maitiro Ekugadzira Akaoma
   Kugadzirwa kwema electrode e graphite ane simba rakawanda kunosanganisira matanho akawanda, anosanganisira calcination yezvinhu zvisina kugadzirwa, kusanganisa, kuumba, kubika, kuisirwa mudumbu, graphitization, uye machining. Danho rega rega rinoda kudzora zvakanyanya ma process parameters kuti ive nechokwadi chekuti chigadzirwa chakanaka. Graphitization, danho rinokosha, rinoda kurapwa patembiricha inodarika 2,000°C kuti ishandure chimiro chezvinhu zvekabhoni kuita makristaro e graphite, zvichiwedzera conductivity yemagetsi uye kuramba kupisa kwakanyanya. Maitiro aya haasi ekushandisa simba chete asiwo anoda mari yakawanda mumidziyo, zvichiwedzera mari yekugadzira.

3. Zvakanakira Kushanda Kwakakosha
   Maelectrode egrafiti ane simba guru kwazvo anoratidza hunhu hwakanaka, hwakadai sekusasimba kwakaderera, kusimba kwakakwira, kusasimba kweoxidation, kushivirira kupisa kwakanyanya, uye kushandiswa kushoma. Kusimba kwadzo kunowanzova pakati pe4-6 μΩ·m, zvichiita kuti magetsi ashande zvakanaka mumaovheni emagetsi kuti agadzire kupisa kwakakwana kwekunyungudutsa simbi nekunatswa kwayo. Zvichienzaniswa nemaelectrode egrafiti ane simba rakawanda uye ane simba guru, mavari esimba guru anogona kutsungirira kusimba kwakakwirira kwemagetsi, kuderedza nguva yekunyungudutsa simbi yakasakara, kuderedza kushandiswa kwemagetsi, uye kuvandudza kushanda zvakanaka kwekugadzira. Mabhenefiti aya anoita kuti kushandiswa kwawo kwakapararira mukugadzira simbi, kugadzirwa kwephosphorus yero, kunyungudutsa silicon mumaindasitiri, nedzimwe nzvimbo, zvichiwedzera kudiwa kwakasimba kwemusika.

4. Maitiro eKudiwa kweZvipo
   Mumakore achangopfuura, kumukazve kweindasitiri yesimbi pasi rose uye kukura nekukurumidza muzvikamu zvitsva zvesimba nezvinhu zvepamusoro zvakakurudzira kudiwa kwakanyanya kwema electrode e graphite ane simba rakawanda. Zvisinei, zvichidziviswa nekuwanikwa kwezvinhu zvakagayiwa zvishoma uye maitiro akaoma ekugadzira, kukura kwezvinhu kwave kunonoka, zvichiwedzera kusawirirana pakati pezvinodiwa. Zvichienderana neizvi, mitengo yema electrode e graphite ane simba rakawanda yakakwira zvega.
