Nekukura kuri kuita indasitiri yealuminium yemagetsi, indasitiri yeanode yekubikisa aluminium yave nzvimbo itsva yekudyara mari, kugadzirwa kweanode yekubikisa aluminium kuri kuwedzera, petroleum coke ndiyo inonyanya kushandiswa muanode yekubikisa aluminium, uye ma index ayo achava nemhedzisiro yakati pamhando yezvigadzirwa.
Zviri mukati mesarufa
Huremu hwesarufa mupetroleum coke hunonyanya kuenderana nehunhu hweoiri isina kuchekwa. Kazhinji, kana huwandu hwesarufa mupetroleum coke hwakaderera, kushandiswa kweanode kunoderera nekuwedzera kwehuwandu hwesarufa, nekuti sarufa inowedzera mwero wekukanda kweasphalt uye inoderedza porosity yekubika kweasphalt. Panguva imwe chete, sarufa inosanganiswawo netsvina yesimbi, zvichideredza Catalysis netsvina yesimbi kudzvinyirira reactivity yecarbon dioxide uye reactivity yemhepo yecarbon anodes. Zvisinei, kana huwandu hwesarufa hwakanyanya, huchawedzera brittleness yekupisa kwecarbon anode, uye nekuti sarufa inonyanya kushandurwa kuita gas phase muchimiro chemaoxides panguva ye electrolysis process, ichakanganisa zvakanyanya electrolysis environment, uye kumanikidzwa kwekuchengetedza nharaunda kuchave kukuru. Pamusoro pezvo, sulfuration inogona kuumbwa pa anode rod Iron film, zvichiwedzera kudonha kwevoltage. Sezvo kupinzwa kwemafuta asina kuchekwa munyika yangu kuri kuramba kuchiwedzera uye nzira dzekugadzirisa dzichiramba dzichivandudzika, maitiro e sarufa isina kusimba haadzivisiki. Kuti vagadzirire shanduko muzvinhu zvakagadzirwa, vagadziri veanode yakabikwa kare pamwe neindasitiri yearuminiyamu yemagetsi vakaita shanduko dzakawanda dzetekinoroji uye kufambira mberi kwetekinoroji. Kubva kuanode yakabikwa kare yemuno muChina. Sekuferefeta kwemakambani ekugadzira, petroleum coke ine sulfur content inosvika 3% inogona kunyudzwa zvakananga mu calcium.
Zvinhu zvekutevera
Zvinhu zvinotevedzana zviri mu petroleum coke zvinosanganisira Fe, Ca, V, Na, Si, Ni, P, Al, Pb, nezvimwewo. Nekuda kwemafuta akasiyana-siyana emafuta ekuchenesa petroleum, kuumbwa uye huwandu hwezvinhu zvinotevedzana zvakasiyana zvikuru. Zvimwe zvinhu zvinotevedzana zvinounzwa kubva mumafuta asina kucheneswa, akadai seS, V, nezvimwewo. Zvimwe simbi dzealkali nesimbi dzealkaline zvichaunzwawo, uye huwandu hwedota huchawedzerwa panguva yekufambisa nekuchengetedza, senge Si, Fe, Ca, nezvimwewo. Hunhu hwezvinhu zvinotevedzana zviri mu petroleum coke hunokanganisa zvakananga hupenyu hwebasa re anode dzakabikwa kare uye mhando uye giredhi rezvigadzirwa zve electrolytic aluminum. Ca, V, Na, Ni nezvimwe zvinhu zvine simba guru re catalytic pa anodic oxidation reaction, iyo inokurudzira selective oxidation ye anode, zvichiita kuti anode idonhedze slag nema blocks, uye inowedzera kushandiswa kwakanyanya kwe anode; Si naFe zvinonyanya kukanganisa mhando ye primary aluminium, uye huwandu hweSi hunowedzera. Ichawedzera kuoma kwealuminium, inoderedza conductivity yemagetsi, uye kuwedzera kwehuwandu hweFe kune simba guru pa plasticity uye corrosion resistance ye aluminum alloy. Kana zvabatanidzwa nezvinodiwa chaizvo zvekugadzira zvemabhizinesi, huwandu hwezvinhu zvidiki zvakaita seFe, Ca, V, Na, Si, uye Ni mu petroleum coke hunofanira kuganhurirwa.
Zvinhu zvinoshanduka-shanduka
Kuwanda kwehuwandu hwemafuta anoputika mu petroleum coke kunoratidza kuti chikamu chisina kubikwa chinotakurwa zvakanyanya. Kuwanda kwehuwandu hwemafuta anoputika kunokanganisa huwandu hwemafuta anoputika uye kuderedza goho remafuta anoputika, asi huwandu hwakakodzera hwemafuta anoputika hunobatsira kuti mafuta anoputika anyure mu petroleum coke. Mushure mekunge mafuta anoputika anyure mu petroleum coke pakupisa kwakanyanya, huwandu hwemafuta hunoderera. Sezvo vashandisi vakasiyana vaine zvavanotarisira zvakasiyana nezvemafuta anoputika, pamwe chete nezvinodiwa chaizvo nevagadziri nevashandisi, zvinotarisirwa kuti mafuta anoputika haafanire kudarika 10%-12%.
Dota
Zvinhu zvisina kupiswa (trace elements) zvinosara mushure mekunge chikamu chinotsva chepetroleum coke chapiswa zvachose kana tembiricha yakakwira ye850 degrees uye mhepo ichitenderera zvinonzi ash. Chinangwa chekuyera ash ndechekuona huwandu hwezvinhu zvisina kuchena (trace elements) kuti zvakadii, kuitira kuongorora mhando yepetroleum coke. Kudzora huwandu hweash kuchadzorawo zvinhu zvisina kuchena. Kuwanda kweash kuchakanganisa mhando yeanode pachayo nearuminiyamu yekutanga. Pamwe chete nezvinodiwa chaizvo zvevashandisi uye mamiriro chaiwo ekugadzirwa kwemabhizinesi, zvinorayirwa kuti huwandu hweash hahufanirwe kudarika 0.3%-0.5%.
Hunyoro
Manyuko makuru emvura mu petroleum coke: Chekutanga, kana coke tower yaburitswa, petroleum coke inoburitswa mudziva re coke ichichekwa ne hydraulic; chechipiri, kubva pakuona kwekuchengetedzeka, mushure mekunge coke yaburitswa, petroleum coke isina kutonhodzwa zvakakwana inofanira kupfapfaidzwa kuti itonhore. Chechitatu, petroleum coke inounganidzwa mumhepo yakashama mumadziva e coke nenzvimbo dzekuchengetera zvinhu, uye hunyoro hwayo huchakanganiswawo nemamiriro ekunze; chechina, petroleum coke ine maumbirwo akasiyana uye kugona kwakasiyana kwekuchengetedza hunyoro.
Zviri muCoke
Hukuru hwechimedu chepetroleum coke hune simba guru pakubuda kwechinhu chaicho, kushandiswa kwesimba uye calcium coke. Petroleum coke ine huwandu hwakawanda hwehupfu hwecoke inorasikirwa necarbon yakawanda panguva yekupiswa kwemafuta. Kupfura nezvimwe zvinhu zvinogona kukonzera matambudziko akadai sekupwanyika kwemuviri wechoto nekukurumidza, kupisa zvakanyanya, kuvharika kwevharuvhu inoburitsa mvura, kupwanywa kwe calcined coke nyore nyore, uye kukanganisa hupenyu hwe calciner. Panguva imwe chete, huwandu hwechokwadi, huwandu hwepombi, porosity, uye simba re calcined coke, Resistivity uye oxidation performance zvine simba guru. Zvichienderana nemamiriro chaiwo ekugadzirwa kwepetroleum coke yemumba, huwandu hwehupfu hwecoke (5mm) hunodzorwa mukati me30%-50%.
Zvakabikwa nekokkok
Shot coke, inozivikanwawo se spherical coke kana shot coke, yakaoma, yakakora uye haina maburi, uye inowanikwa muchimiro che spherical molded masses. Pamusoro pe shot coke yakatsetseka, uye chimiro chemukati hachienderane nekunze. Nekuda kwekushaikwa kwemaburi pamusoro, kana uchikanya ne binder coal tar pitch, zvinonetsa kuti binder ipinde mukati me coke, zvichikonzera kusununguka kwe bonding uye kukanganisa mukati. Pamusoro pezvo, thermal expansion coefficient ye shot coke yakakwira, izvo zvinogona kukonzera thermal shock cracks kana anode yabikwa. Petroleum coke inoshandiswa mu anode yakabikwa kare haifanirwe kunge iine shot coke.
