Eyona nto isetyenziswa kakhulu ekuveliseni i-graphite electrode yi-calcined petroleum coke. Ngoko ke loluphi uhlobo lwe-calcined petroleum coke olufanelekileyo ekuveliseni i-graphite electrode?
1. Ukulungiswa kwe-coking eluhlaza kufuneka kuhambelane nomgaqo wokuvelisa i-petroleum coke esemgangathweni ophezulu, kwaye ukulebhelisha i-petroleum coke esemgangathweni ophezulu kufuneka kube nesakhiwo esinamaqhina ngakumbi. Indlela yokuvelisa ibonisa ukuba ukongeza i-20-30% ye-thermal cracking residue coke kwi-coking eluhlaza oyile kunomgangatho ongcono, onokuhlangabezana neemfuno zemveliso ye-graphite electrode.
2. Amandla aneleyo olwakhiwo.
Ububanzi bezinto ezikrwada ngaphambi kokutyumza, ukunyibilika, ixesha lokutyumza ukunciphisa ukucolwa, ukuhlangabezana neemfuno zokudibanisa ubungakanani beenkozo zesikwere.
3. Utshintsho lomthamo we-coke kufuneka lube luncinci emva kokuqhekeka, nto leyo enokunciphisa uxinzelelo lwangaphakathi kwimveliso olubangelwa kukudumba kwemveliso ecinezelweyo kunye nokuncipha kwenkqubo yokosa kunye ne-graphitization.
4. I-Coke kufuneka ibe lula ukuyi-graphitization, iimveliso kufuneka zibe nokumelana okuphantsi, ukuqhuba okuphezulu kobushushu kunye ne-coefficient ephantsi yokwandiswa kobushushu.
5. Ukuguquguquka kweCoke kufuneka kube ngaphantsi kwe-1%,I-volatile matter ibonisa ubunzulu be-coking kwaye ichaphazela uthotho lweempawu.
6. I-Coke mayiyosiwe kwi-1300℃ kangangeeyure ezi-5, kwaye ubunzima bayo bokwenyani abufanele bube ngaphantsi kwe-2.17g/cm2.
7. Umxholo wesalfure kwi-coke akufuneki ube ngaphezulu kwe-0.5%.
UMntla Melika kunye noMzantsi Melika ngabavelisi abakhulu be-petroleum coke ehlabathini, ngelixa iYurophu ngokuyintloko izimele kwi-petroleum coke. Abavelisi abakhulu be-petroleum coke e-Asia yiKuwait, Indonesia, Taiwan kunye neJapan kunye namanye amazwe kunye nemimandla.
Ukususela ngeminyaka yoo-1990, ngenxa yophuhliso olukhawulezileyo loqoqosho lwaseTshayina, imfuno yeoyile ibikhula minyaka le.
Xa ubungakanani bokucubungula ioyile ekrwada busanda kakhulu, inani elikhulu le-petroleum coke, imveliso ephuma ekucoceni ioyile ekrwada, ngokuqinisekileyo liya kuveliswa.
Ngokwendlela esasazwa ngayo imveliso ye-petroleum coke eTshayina, ummandla wasempuma weTshayina ungowokuqala, ubala ngaphezulu kwama-50% emveliso iyonke ye-petroleum coke eTshayina.
Ilandelwa ngummandla wasempuma-mpuma kunye nommandla wasentshona-ntshona.
Umxholo wesalfure we-petroleum coke udlala indima ebalulekileyo ekusetyenzisweni kwayo nakwixabiso layo, kwaye ukuveliswa kwe-graphitized petroleum coke kuthintelwe yimithetho engqongqo yokusingqongileyo kwamanye amazwe, ethintela ukutshiswa kwe-petroleum coke enomxholo ophezulu wesalfure kwiindawo ezininzi zokucola kunye nezityalo zamandla kweli lizwe.
I-petroleum coke ekumgangatho ophezulu nene-sulfur ephantsi isetyenziswa kakhulu kwimizi-mveliso yentsimbi, i-aluminium kunye nekhabhoni. Ukwanda kwemfuno kunyusa ixabiso le-petroleum coke izihlandlo ezininzi.
Kwiminyaka yakutshanje, ukusetyenziswa okubonakalayo kwe-petroleum coke eTshayina kuyaqhubeka nokukhula ngesantya esiphezulu, kwaye imfuno ye-petroleum coke kuzo zonke iimarike zabathengi iyaqhubeka nokukhula.
I-aluminiyam ithatha ngaphezulu kwesiqingatha sayo yonke i-petroleum coke esetyenziswayo eTshayina. Isetyenziswa kakhulu kwi-anode ebhakiweyo kwangaphambili, kwaye imfuno ye-sulfur coke ephakathi nephantsi iphezulu.
Iimveliso zekhabhoni zimalunga nesinye kwisihlanu semfuno ye-petroleum coke, esetyenziswa kakhulu ekulungiseleleni ii-electrode ze-graphite. Ii-electrode ze-graphite eziphambili zinexabiso eliphezulu kwaye zinenzuzo enkulu.
Ukusetyenziswa kwepetroli kwenza malunga nesinye kwishumi, kwaye izityalo zamandla, iifektri zeporcelain kunye neeglasi zisebenzisa ngaphezulu.
Umlinganiselo wokusetyenziswa kweshishini lokunyibilikisa isinyithi usuka kwisinye ukuya kwishumi elinesibini, ukusetyenziswa kwesinyithi esenziwe ngentsimbi.
Ukongeza, imfuno yeshishini lesilicon nayo ibalulekile.
Inxalenye yokuthunyelwa kwamanye amazwe yeyona incinci kakhulu, kodwa imfuno ye-petroleum coke ekumgangatho ophezulu kwimarike yaphesheya isafanele ukujongwa phambili. Kukwakho nesabelo esithile se-high-sulfur coke, kunye nokusetyenziswa kwekhaya.
Ngophuhliso loqoqosho lwaseTshayina, iifektri zentsimbi zasekhaya zaseTshayina, abanyibilikisi be-aluminium kunye nezinye iingenelo zoqoqosho ziphucuke kancinci kancinci, ukuze kwandiswe imveliso kunye nomgangatho weemveliso, amashishini amaninzi amakhulu aye athenga kancinci kancinci i-graphenized petroleum coking carbonizer. Imfuno yasekhaya iyanda. Kwangaxeshanye, ngenxa yeendleko eziphezulu zokusebenza, imali enkulu yotyalo-mali kunye neemfuno zobugcisa eziphezulu ekuvelisweni kwe-graphitized petroleum coke, akukho mashishini maninzi emveliso kwaye uxinzelelo oluncinci lokhuphiswano okwangoku, ngoko ke, imakethi inkulu, unikezelo luncinci, kwaye unikezelo lulonke luphantse lube ngaphantsi kwemfuno.
Okwangoku, imeko yemarike ye-petroleum coke eTshayina kukuba, kukho iimveliso ze-petroleum coke ezine-sulfur eninzi, ezisetyenziswa kakhulu njengepetroli; Iimveliso ze-petroleum coke ezine-sulfur ephantsi zisetyenziswa kakhulu kwi-metallurgy nakwi-export; Iimveliso ze-petroleum coke eziphambili kufuneka zingeniswe kwamanye amazwe.
Inkqubo yokubala i-coke yepetroleum yangaphandle igqitywa kwindawo yokuhluza, i-coke yepetroleum eveliswa yindawo yokuhluza ingena ngqo kwiyunithi yokubala i-coke ukuze ihluzwe.
Ekubeni kungekho sixhobo sokubala i-calcination kwiindawo zokucola zasekhaya, i-petroleum coke eveliswa ziindawo zokucola ithengiswa ngexabiso eliphantsi. Okwangoku, i-petroleum coke yaseTshayina kunye ne-calcining yamalahle zenziwa kushishino lwesinyithi, olufana nezityalo zekhabhoni, izityalo ze-aluminium, njl.
