Ukwenziwa kwe-graphitization, njengenkqubo ephambili yemveliso, kudla ngokwenziwa kwiintlobo ezine zezixhobo: i-Acheson graphitization furnace, i-internal series graphitization furnace, i-box-type graphitization furnace, kunye ne-continuous graphitization furnace. Uhlalutyo oluthile lulandelayo:
Isithando somlilo se-Acheson Graphitization
Njengesixhobo esiqhelekileyo semveli, isebenzisa umgaqo wokufudumeza ukumelana nobushushu ukunyusa ubushushu bube yi-2,800-3,000°C, nto leyo eyenza ifaneleke kwimveliso ye-graphite ecocekileyo kakhulu. Olu hlobo lwesithando lunesakhiwo esilula nesiqinileyo. Nangona kunjalo, luneengxaki ezifana nomjikelo wemveliso omde, ukusetyenziswa kwamandla aphezulu (malunga ne-4,000-4,800 kWh/t), kunye nokusebenza okuphantsi. Okwangoku, iinkampani ezifana nePutailai kunye neShanshan zisamkela kakhulu obu buchwephesha kwaye ziphucule ukusebenza kakuhle kwamandla ngokuphucula umlinganiselo wezixhobo zokulwa kunye nokuphucula isakhiwo sobushushu.
Isithando somlilo seGraphitization yothotho lwangaphakathi
Esi sithando somlilo sishushu ngokuthe ngqo ngee-electrode ngokwazo, sisusa isidingo sezixhobo zokumelana nobushushu. Sibonelela ngeenzuzo ezifana nokusebenza kakuhle kobushushu, ixesha elifutshane lokusebenzisa amandla (iiyure ezi-1-2 kuphela ngexesha lobushushu obuphezulu), kunye nokusetyenziswa kwamandla okuphantsi (malunga ne-3,300-4,000 kWh/t). Iintlobo zesithando somlilo ziquka uhlobo lwe-I, uhlobo lwe-U, uhlobo lwe-W, kunye nohlobo lwe-plum-blossom, apho uhlobo lwe-U lusetyenziswa kakhulu. Izityalo zekhabhoni eJamani, eMelika, naseJapan ziye zamkela obu buchwepheshe ngomlinganiselo omkhulu ukuvelisa ii-electrode ezinkulu ze-graphite ezinamandla aphezulu. Nangona kunjalo, ubushushu baso obukhulu besithando somlilo (malunga ne-2,800°C) buphantsi kancinci kunobo besithando somlilo sase-Acheson.
Isithando somlilo seGraphitization sohlobo lwebhokisi
Le teknoloji isebenzisa iipleyiti zekhabhoni okanye zegrafiti ukwakha isakhiwo sebhokisi, isebenzisa izinto ngokwazo njengesixhobo sokufudumeza esichaseneyo endaweni yezinto zemveli ezichaseneyo ezisekelwe kwi-coke. Ngokuphucula ukusasazwa kwentsimi yobushushu, kunciphisa ukusetyenziswa kwamandla. Nangona kunjalo, ijongene nemingeni efana ne-oxidation yezinto, ukusebenza kakuhle kobushushu obuphantsi, kunye nokusasazwa kobushushu obungalinganiyo ngaphakathi kwesithando. Iinkampani ezifana neHebei Kuntian kunye neShanshan Co., Ltd. zineepatenti ezifanelekileyo kwaye ziphucule ukuhambelana kwemveliso ngokuphucula ukutywinwa kwebhokisi kunye nokwenza ngcono i-power-on curve.
Isithando somlilo esiqhubekayo seGraphitization
Esi sithando somlilo sivumela ukondla izinto rhoqo, unyango oluphezulu (2,500-3,000°C), kunye nokukhupha ubushushu. Sibonelela ngeenzuzo ezifana nokusebenza kakuhle kwemveliso, ukusetyenziswa kwamandla aphantsi, kunye nenqanaba eliphezulu lokuzenzekelayo. Ulawulo lobushushu lufezekiswa ngokufudumeza okuxhathisayo (indlela yokufudumeza yangaphandle) okanye ukuzifudumeza ngokwakho (indlela yokufudumeza yangaphakathi). Nangona kunjalo, indlela yokufudumeza yangaphakathi inzima ngakumbi ukuyisebenzisa ngenxa yokuzifudumeza ngokwakho kunye nokuhamba kwezinto. Iinkampani ezifana neKuntian kunye neBTR zikhuthaza uphuhliso lobu buchwephesha, okulindeleke ukuba buthathe indawo yeendlela zemveliso ezikhawulezileyo kwixesha elizayo.
Iindlela Zoshishino Neengcebiso Zokukhetha Izixhobo
- Ukuphucula Ukusetyenziswa Kwamandla: Iifeni zangaphakathi zochungechunge kunye neefeni zohlobo lwebhokisi zinciphisa ukusetyenziswa kwamandla ngokunciphisa ukusetyenziswa kwezinto zokumelana, ngelixa iifeni eziqhubekayo zonyusa ukusebenza kakuhle ngokubuyisela ubushushu, zihambelana nemfuno yemveliso engabizi kakhulu phantsi kweenjongo zokungathathi cala kwekhabhoni.
- Ukuphucula Ukusebenza Kakuhle: Izitofu eziqhubekayo zivumela imveliso engaphazanyiswa iiyure ezingama-24, kunye nomthamo womgca omnye ofikelela kwiitoni ezili-10,000, ngaphezu kokuphindwe kathathu imveliso yezixhobo zemveli. Oku kuzenza zifaneleke kumashishini amakhulu ezinto ze-anode.
- Umgangatho weMveliso: Isithando somlilo sase-Acheson sisathandwa kakhulu kwimveliso yegrafiti ephezulu ngenxa yobushushu obufanayo obuphezulu, ngelixa isithando somlilo esiqhubekayo sihlangabezana neemfuno eziqinileyo zokungaguquguquki kwezixhobo zebhetri yamandla ngokulawula ubushushu ngokuchanekileyo.
- Ukuhlaziywa kobuchwepheshe: Iinkqubo ezintsha ezifana ne-microwave graphitization kunye ne-plasma graphitization ziphantsi kophando nophuhliso, ezinokuphula umda wobushushu be-3,000°C kwaye zinciphise ngakumbi amaxesha okucubungula kwixesha elizayo.
