UHP Ultra-High Power Graphite Electrode Iinkcukacha
I-UHP (i-Ultra-High Power) ye-graphite electrode yimathiriyeli engundoqo eqhubayo kumashishini anamhlanje esinyithi, eyilelwe ukumelana nomthwalo ogqithisileyo wangoku. Ngokuqhelekileyo zisetyenziselwa umbane we-arc furnace steelmaking kunye ne-high-end-end alloy smelting, kunye neenzuzo zabo zokusetyenziswa kwamandla aphantsi kunye nokuzinza okuphezulu kubenza babe yinto ebalulekileyo ekuphuculeni ishishini.
I. Inkcazo engundoqo kunye neeNzuzo zokuSebenza
-Indawo engundoqo: Iyakwazi ukumelana noxinaniso lwangoku olungaphezulu kwe-25 A/cm² (ukuya kuma-40 A/cm²), ukuzuza ukunyibilika okusebenzayo ngobushushu obuphezulu be-arcs obungaphezulu kwe-3000°C obuveliswe phakathi kwencam ye-electrode kunye nentlawulo yesithando somlilo. Ziyinxalenye engundoqo ye-ultra-high power electric arc furnaces (EAFs) kunye neziko lokusulungekisa.
-Iiparamitha zokuSebenza eziphambili:
- I-Conductivity yoMbane: Ukuxhathisa ≤ 6.2 μΩ·m (ezinye iimveliso eziphezulu eziphantsi njenge-4.2 μΩ·m), ziphakame kakhulu kunee-electrode eziqhelekileyo zamandla aphezulu (HP);
- Amandla omatshini: Amandla e-Flexural ≥ 10 MPa (amalungu angafikelela kwi-MPa engama-20), akwazi ukumelana neempembelelo zokutshaja kunye nokungcangcazela kwe-electromagnetic;
- Ukuzinza kwe-Thermal: I-Coefficient yokwandiswa kwe-thermal kuphela i-1.0-1.5 × 10⁻⁶/℃, ayinakwenzeka ukukrazula okanye i-spalling phantsi kokufudumeza ngokukhawuleza kunye nokupholisa;
- Iimpawu zeMichiza: Umxholo we-ash ≤ 0.2%, ubuninzi be-1.64-1.76 g / cm³, i-oxidation enamandla kunye nokumelana nokubola, okubangelwa ukusetyenziswa okuncinci ngetoni yensimbi.
II. Inkqubo yeMveliso enguNdoqo kunye neMathiriyeli ekrwada
- Izinto ezingundoqo ze-Raw: Ukusebenzisa i-100% ye-petroleum-high-quality-based coke yenaliti (ukuqinisekisa ukwandiswa okuphantsi kunye ne-conductivity ephezulu), idibaniswe ne-modified medium-temperature pitch binder (i-softening point 108-112 ° C) kunye ne-quinoline ephantsi enganyibilikiyo (QI ≤ 0.5%). - Inkqubo enguNdoqo: Inkqubo ibandakanya ukuxuba isithako kunye nokuxova → ukubumba i-extrusion → ukubala (kabini) → ukufakwa koxinzelelo oluphezulu (kube kanye kumzimba we-electrode, kathathu kwikhonkco) → igraphitization (inkqubo yomgca ngaphezulu kwe-2800℃) → ukusetyenzwa ngoomatshini. Ukulawulwa kweqondo lokushisa ngokuchanekileyo kunye nokulungiswa kweparameter kuqinisekisa ukuchaneka kwemveliso (ukunyamezela ngokuthe tye ± 10mm / 50m) kunye nokuzinza kokusebenza.
- Inkqubo ye-Innovation: Inkqubo ephuculweyo "ye-impregnation enye, i-calcination emibini" inciphisa umjikelezo wemveliso ngeentsuku ze-15-30 xa kuthelekiswa neendlela zendabuko, ukunciphisa iindleko malunga ne-2000 RMB / ton, ngelixa igcina ukuxhathisa ukothuka kwe-thermal.
III. Iimeko zeSicelo eziPhambili
- Ummandla oPhambili: I-AC / DC i-ultra-high power electric arc furnace steelmaking, esetyenziselwa ukuveliswa kwensimbi ephezulu ye-alloy kunye nentsimbi ekhethekileyo, ukuphucula ukusebenza kakuhle kwe-smelting ngaphezu kwe-30% kunye nokunciphisa ukusetyenziswa kwamandla nge-15% -20%;
- Izicelo ezongeziweyo: Ukunyibilika kwezinto eziphezulu eziphezulu ezifana ne-silicon ye-industrial, i-ferrosilicon, kunye ne-yellow phosphorus kwii-arc eziphantsi kwamanzi, kunye nokuveliswa kweemveliso zokushisa eziphezulu ezifana ne-corundum kunye ne-abrasives, ukulungelelaniswa neenkcukacha ezahlukeneyo zombane wombane (ububanzi obuyi-12-28 intshi, i-200000000000000000000-1200 yangoku umthamo we-2200-200 yangoku).
IV. Ixabiso leShishini kunye neeNdlela zoPhuhliso
- Ixabiso eliPhambili: Ukuqhuba inguqu yombane we-arc steelmaking ukuya kwiinkqubo "ezikhawulezayo, ezicocekileyo, kunye nokusebenza kakuhle", yinto ephambili yokugcina amandla kunye nokunciphisa ukukhutshwa kwishishini lentsimbi kunye nokujongana neentlawulo zekhabhoni. Isabelo sayo semarike kulindeleke ukuba sidlule i-60% yemfuno ye-graphite electrode epheleleyo ngo-2025, ngexabiso elimalunga ne-18,000 RMB / ton;
- Ulwalathiso lwezobuchwephesha: Ugxininiso kwi-graphene coating modification (ukunciphisa ukuchasana noqhagamshelwano nge-40%), i-silicon carbide i-composite composite reinforcement, imveliso ehlakaniphile (i-digital twin process simulation), kunye noqoqosho lwesetyhula (izinga lokubuyisela uthuli 99.9% + inkunkuma yokubuyisela ukushisa), ukuqhubela phambili ukuphucula ubomi kunye nobuhlobo bendalo.
