Eyona nto isetyenziswayo ekuveliseni i-electrode yegraphite yi-calcined petroleum coke.Ngoko ke luhlobo luni lwe-coke ye-petroleum e-calcined olufanelekileyo ukuveliswa kwe-electrode yegraphite?
1. Ukulungiswa kwe-coking oil ekrwada kufuneka kuhambelane nomgaqo wokuvelisa icoke yepetroleum ekumgangatho ophezulu, kwaye ukuleyibhelishwa kwecoke yepetroleum ekumgangatho ophezulu kufuneka kube nesakhiwo esine-fibrous ngakumbi.Ukwenziwa kwemveliso kubonisa ukuba ukongeza i-20-30% ye-coke ye-thermal yokuqhekeka kwe-coke kwi-coking yeoli ekrwada inomgangatho ongcono, onokuhlangabezana neemfuno zemveliso ye-graphite electrode.
2. Ukuqina okwaneleyo kolwakhiwo.
Idayamitha ekrwada yokucolwa kwangaphambili, ukunyibilika, ukutyumza ixesha lokunciphisa ukucolwa, kuhlangatyezwana neemfuno zokwakheka kobungakanani beenkozo zesikwere.
3. Ukutshintshwa kwevolumu ye-coke kufuneka ibe yincinci emva kokuphuka, enokunciphisa uxinzelelo lwangaphakathi kwimveliso ebangelwa ukubuyisela umva kwemveliso ecinezelekileyo kunye nokunciphisa inkqubo yokugaya kunye ne-graphitization.
4. I-Coke kufuneka ibe lula kwi-graphitization, iimveliso kufuneka zibe nokuchasana okuphantsi, ukuhanjiswa okuphezulu kwe-thermal kunye ne-coefficient ephantsi yokwandiswa kwe-thermal.
5. I-coke volatilization kufuneka ibe ngaphantsi kwe-1%,Umba oguquguqukayo ubonisa ubunzulu be-coking kwaye uchaphazela uluhlu lweempawu.
6. I-Coke kufuneka yosiwe kwi-1300 ℃ ngeeyure ze-5, kwaye ubunzima bayo bokwenyani kufuneka bungabi ngaphantsi kwe-2.17g / cm2.
7. Umxholo wesulfure kwi-coke akufanele ube ngaphezu kwe-0.5%.
UMntla Melika kunye noMzantsi Melika ngabona bavelisi abakhulu bepetroleum coke kwihlabathi, ngelixa iYurophu ikwazi ukwanelisa icoke yepetroleum.Abavelisi abakhulu be-petroleum coke e-Asia yi-Kuwait, i-Indonesia, i-Taiwan kunye ne-Japan kunye namanye amazwe kunye nemimandla.
Ukusukela ngeminyaka yoo-1990, ngophuhliso olukhawulezayo loqoqosho lwaseTshayina, imfuno ye-oyile ibisanda unyaka nonyaka.
Xa umyinge wokwenziwa kwe-oyile ekrwada usanda kakhulu, isixa esikhulu se-petroleum coke, imveliso ephuma kwi-oyile ekrwada yokusulungekiswa, ngokuqinisekileyo iya kuveliswa.
Ngokokusasazwa kommandla wemveliso ye-petroleum coke e-China, ummandla osempuma we-China ukwinqanaba lokuqala, ubala ngaphezu kwe-50% yesiphumo esipheleleyo se-petroleum coke e-China.
Ilandelwa ngummandla osemntla-mpuma kunye nommandla osemntla-ntshona.
Umxholo wesulfure we-petroleum coke udlala indima ebalulekileyo kwisicelo kunye nexabiso, kwaye ukuveliswa kwe-petroleum coke ye-graphitized kunqunyelwe yimimiselo engqongqo yendalo engaphandle, ethintela ukutshiswa kwe-petroleum coke kunye nomxholo ophezulu wesulfure kwiindawo ezininzi zokucoca kunye nezityalo zamandla kwi ilizwe.
Umgangatho ophezulu kunye ne-sulphur petroleum coke ephantsi isetyenziswa kakhulu kwi-steel, i-aluminium kunye ne-carbon industry.Imfuno ekhulayo yokwandisa ixabiso le-petroleum coke ngamaxesha amaninzi.
Kwiminyaka yakutshanje, ukusetyenziswa okubonakalayo kwe-petroleum coke e-China kuyaqhubeka ukukhula ngesantya esiphezulu, kwaye imfuno ye-petroleum coke kuzo zonke iimarike zabathengi iyaqhubeka isanda.
I-Aluminiyam yenza ngaphezu kwesiqingatha sokusetyenziswa kwepetroleum coke eChina.Isetyenziswa kakhulu kwi-anode ebhakiweyo ngaphambili, kwaye imfuno yecoke yesulfure ephakathi kunye nesezantsi inkulu.
Iimveliso zekhabhoni zithatha malunga nesinye kwisihlanu semfuno yepetroleum coke, esetyenziswa kakhulu ekulungiseni iielectrode zegraphite.Iielectrode zegraphite eziphambili zinexabiso eliphezulu kwaye zinengeniso ephezulu.
Ukusetyenziswa kwepetroli kwenza malunga nesinye eshumini, kwaye iifektri zamandla, i-porcelain kunye neglasi zisebenzisa ngaphezulu.
Umlinganiselo wokusetyenziswa kweshishini lokunyibilikisa enye - yamashumi amabini, ukusetyenziswa kwentsimbi yokugaya intsimbi.
Ukongeza, imfuno yomzi-mveliso we-silicon ikwanamandla okubalelwa.
Inxalenye yokuthumela ngaphandle ithatha eyona nxalenye incinci, kodwa imfuno yepetroleum coke ekumgangatho ophezulu kwimarike yaphesheya isakufanele ukujongwa kuyo.Kukho nesabelo esithile se-coke ephezulu yesulfure, kunye nokusetyenziswa kokusetyenziswa kwasekhaya.
Ngophuhliso loqoqosho lwaseTshayina, iintsimbi zasekhaya zaseTshayina, izinyibilikisi ze-aluminium kunye nezinye iinzuzo zoqoqosho ziye zaphucuka ngokuthe ngcembe, ukuze kwandiswe imveliso kunye nomgangatho weemveliso, amashishini amakhulu amaninzi athe ngokuthe ngcembe athenge i-graphenized petroleum coking carbonizer.Imfuno yasekhaya iyakhula. Ngexesha elifanayo, ngenxa yeendleko eziphezulu zokusebenza, inkunzi enkulu yotyalo-mali kunye neemfuno eziphezulu zobugcisa kwimveliso yepetroleum coke yegraphitized, akukho mashishini amaninzi emveliso kunye noxinzelelo oluncinci olunokhuphiswano okwangoku, ngoko ke, imarike inkulu, ukubonelela encinci, kwaye unikezelo lulonke luphantse lube ngaphantsi kwemfuno.
Okwangoku, imeko yemarike yepetroleum yecoke yase China yile, intsalela yemveliso ye sulfur yepetroleum coke ephezulu, esetyenziswa ikakhulu njengamafutha;Imveliso yecoke yesulphur ephantsi yesulfure isetyenziswa ikakhulu kukwenziwa kwesinyithi kunye nokuthumela ngaphandle;Iimveliso zepetroleum zecoke ezikumgangatho ophezulu kufuneka zingeniswe kumazwe angaphandle.
Inkqubo ye-petroleum coke calcination yangaphandle igqitywe kwindawo yokucoca, i-petroleum coke eveliswa yi-refinery iya ngqo kwiyunithi yokubala ukubala.
Ekubeni kungekho sixhobo se-calcination kwii-refineries zasekhaya, i-petroleum coke eveliswa yi-refineries ithengiswa ngokuncinci.Okwangoku, i-petroleum coke yaseChina kunye ne-coal calcining iqhutyelwa kwishishini le-metallurgical, njengesityalo sekhabhoni, isityalo se-aluminium, njl.
