I-coke ye-petroleum e-calcined isetyenziswa kakhulu kwi-anode ebhakiweyo kwangaphambili kunye ne-cathode kwi-aluminium ye-electrolytic, i-recarburizer kwimveliso ye-metallurgical kunye ne-steel, i-graphite electrode, i-silicon yezimboni, i-phosphorus etyheli kunye ne-carbon electrode kwi-ferroalloy, njl.
Ngoko ke, zombini izityalo ze-aluminium ze-electrolytic, izityalo zekhabhoni ezizimeleyo kunye neendawo zokucoca ioyile zinika ingqalelo engakumbi kwinkqubela phambili kunye nophuhliso lwetekhnoloji ye-petroleum coke calcination.
Ekubeni i-coke ye-petroleum ene-calcined inemisebenzi emininzi kangaka, kuyimfuneko ukuphuhlisa izakhono ezintsha zokuvelisa ukuphucula ngakumbi ukusetyenziswa kwe-coke ye-petroleum ene-calcined.
Ingakumbi, isithando somlilo se-calcining sokwenza i-coke ye-petroleum ene-calcium eTshayina sisenendawo entle yophuhliso lobuchwephesha. Kubalulekile ukugxila ekusebenziseni izixhobo ezintsha, uphuhliso lwezitena ze-silica ezikumgangatho ophezulu, ukubuyiselwa kwezixhobo zobushushu obumdaka ngeendlela ezininzi, ukuphuculwa kokwenziwa kwezinto ngokuzenzekelayo, isithando somlilo sokomisa ngokwesayensi kunye nokusebenza okusemgangathweni, ukuze kwenziwe izinga lokusetyenziswa kwe-coke ye-petroleum ene-calcium liphakame.
Isiphumo sokusetyenziswa singcono, ukongeza kwisithando sokunyibilikisa ukuze kuphuhliswe ubomi bokukhula, imveliso ephezulu, ukhuseleko olukrelekrele lokusingqongileyo, isithando soshishino esinoqoqosho.
Ngokukodwa, kuyimfuneko ukudibanisa iteknoloji yokulinganisa amanani kunye nendlela yokwenza imveliso ukuze kuphuculwe ngokwesayensi umgangatho kunye neengxaki zobugcisa ze-coke ye-petroleum e-calcined yaseTshayina, ukuze kuncitshiswe ngakumbi iindleko zemveliso kwaye kuphuculwe ukusebenza kakuhle kwemveliso.
Umlinganiselo wesakhiwo seendleko zetha e-calcined eTshayina
Kwi-electrode yegrafiti esetyenziswa ekwenzeni intsimbi okanye kwi-anode paste (i-electrode yokunyibilikisa) esetyenziswa kwi-aluminium kunye ne-magnesium, ukuze ihlangabezane neemfuno ze-petroleum coke (i-coke), i-coke kufuneka ifakwe i-calcium.
Ubushushu be-calcination buhlala bumalunga ne-1300℃, ngenjongo yokususa i-volatiles ye-tar kangangoko kunokwenzeka.
Ngale ndlela, umxholo we-hydrogen we-petroleum coke reproducts unokuncitshiswa, inqanaba le-graphitization ye-petroleum coke linokuphuculwa, kwaye amandla obushushu aphezulu kunye nokumelana nobushushu kwe-graphite electrode kunokuphuculwa, kwaye ukuhanjiswa kombane kwe-graphite electrode kunokuphuculwa.
Ukutshiswa kwe-calcined kusetyenziswa kakhulu kwimveliso ye-graphite electrode, iimveliso ze-carbon paste, isanti yedayimani, imboni ye-phosphorus ekumgangatho wokutya, imboni ye-metallurgical kunye ne-calcium carbide, phakathi kwazo i-graphite electrode yeyona isetyenziswa kakhulu.
I-coke eluhlaza ingasetyenziselwa ngokuthe ngqo i-calcium carbide njengezinto eziphambili, i-silicon carbide kunye ne-boron carbide njengezinto zokusila ngaphandle kokubumba nokutsha.
Ingasetyenziswa ngqo njenge-coke ye-oven ye-metallurgical okanye i-blast oven wall lining carbon, ingasetyenziswa njengenkqubo yokuphosa i-coke exineneyo, njl.
Ingxelo yophando lwemarike ye-2020-2026 ye-China calcined petrolem coke enzulu malunga nemeko ekhoyo kunye nendlela eqhubekayo yophuhliso "isekelwe kuphando oluninzi lwemarike, ikakhulu ngokusekelwe kwi-National Bureau of Statistics, i-Ministry of Commerce kunye ne-National Development and Reform Commission, iziko lophando lophuhliso lweBhunga leSizwe, umbutho we-calcined coke industry, ulwazi oluhambelanayo noshicilelo lwe-calcined coke ekhaya nakwamanye amazwe, kunye nesiseko seeyunithi zophando lweshishini le-calcined coke ukubonelela ngolwazi oluneenkcukacha,
Idityaniswe nedatha yophando olunzulu lwemarike, esekelwe kwimpembelelo yangoku yoqoqosho olukhulu lwaseTshayina, imigaqo-nkqubo kunye namashishini amakhulu kwishishini le-coke, eli phepha ligxile ekusebenzeni ngokubanzi kweshishini le-coke kunye namashishini angaphantsi anxulumene nalo, kwaye lihlalutya kwaye liqikelele indlela yophuhliso kunye nethemba leshishini le-coke kwixesha elizayo.
Ingxelo ngemeko yangoku kunye nomkhwa wophuhliso lwemarike ye-coke e-calcined eTshayina ukususela ngo-2020 ukuya ku-2026 ekhutshwe yinethiwekhi yophando lweshishini inedatha efike ngexesha nepheleleyo, iitshathi ezityebileyo kunye nokucamngca okubonakalayo. Ngokusekelwe kuhlalutyo olunzulu kunye nokuqikelela imeko yangoku kunye nomkhwa wophuhliso lwemarike ye-coke e-calcined, ithemba lophuhliso lwexesha elizayo lweshishini le-coke e-calcined liye lafundwa.
Ukuze amashishini e-calcining coke asebenze kukhuphiswano olunzima lwemarike olukhoyo, kufuneka kubekho amathuba otyalo-mali, ukulungiswa okufanelekileyo kwesicwangciso seshishini;
Ukuze kukhethwe ithuba elifanelekileyo lotyalo-mali kubatyali-mali abanobuchule, ubunkokeli benkampani buya kwenza ucwangciso olunobuchule, bunike ulwazi lobuchwephesha bemarike kunye neengcebiso ezifanelekileyo zokubhekisela.
"Ingxelo yophando olunzulu kunye nenkqubela phambili yemarike ye-coke e-calcined yaseTshayina ka-2020-2026" yingxelo yobungcali ebaluleke kakhulu kumashishini anxulumene ne-coke e-calcined, iiyunithi zophando, iibhanki, oorhulumente, njl.njl., ukuze baqonde ngokuchanekileyo, ngokupheleleyo nangokukhawuleza indlela yophuhliso lwangoku lweshishini le-coke e-calcined kunye nokuqonda indlela yophuhliso olucwangcisiweyo lwamashishini.
