Kwinkqubo yokuvelisa i-graphitized petroleum coke, izixhobo ezahlukeneyo zifezekisa utshintsho olucwangcisiweyo lwezakhiwo ze-athomu yekhabhoni ngemigaqo yazo yenkqubo eyahlukileyo, kunye neengenelo kunye nokungalungi kwazo okubonakala kakhulu ekusetyenzisweni kwamandla, ukusebenza kakuhle, umgangatho wemveliso, kunye neendleko zokugcinwa kwezixhobo. Apha ngezantsi kukho uhlalutyo lwezixhobo eziphambili, kunye nemigaqo yazo, iingenelo kunye nokungalungi:

I. Isithando somlilo seGraphitization (Izixhobo eziPhambili)

Umgaqo:
Isithando somlilo se-graphitization sisebenzisa unyango lobushushu obuphezulu (ngokuvamile sifikelela kwi-2400-3000°C), sisebenzisa amandla okusebenza kobushushu ukukhuthaza ii-athomu ze-carbon ukuba zitshintshe ukusuka kwisakhiwo esineengqimba ezingalunganga ukuya kwisakhiwo sekristale ye-graphite ecwangcisiweyo, ngaloo ndlela sigqibezela inkqubo ye-graphitization. Ingongoma yaso ixhomekeke ekuboneleleni ngendawo ehlala ihleli nefanayo yobushushu obuphezulu ukuze kuvumeleke ukuhlelwa kwakhona kwesakhiwo see-athomu ze-carbon ngaphakathi kwe-petroleum coke.

Iingenelo:

• Umgangatho weMveliso oPhezulu: Ingavelisa i-graphitized petroleum coke enomxholo ophezulu wekhabhoni, i-sulfur ephantsi, kunye ne-nitrogen ephantsi, ihlangabezana neemfuno zococeko oluphezulu zee-carburizers kwimizi-mveliso yentsimbi ephezulu, intsimbi ekhethekileyo, kunye ne-metallurgical.
• Inkqubo Yokukhula: Njengezixhobo zemveli, indlela yayo yetekhnoloji izinzile kwaye ifanelekile kwimveliso enkulu.

Iingxaki:

• Ukusetyenziswa kwamandla aphezulu: Ukucubungula ngobushushu obuphezulu kufuna amandla ombane amaninzi, nto leyo ethetha malunga ne-50% yexabiso lilonke lemveliso yegrafiti yokwenziwa.
• Umjikelo Omde Wemveliso: Iifurniture ze-graphitization ezizinzileyo zifuna iintsuku ezili-10-20 zokuphola kunye nokukhupha izinto, nto leyo eyandisa umjikelo wemveliso iyonke.
• Iindleko Eziphezulu Zokugcinwa Kwezixhobo: Indawo enobushushu obuphezulu ikhawulezisa ukuguga kwezinto zesithando, nto leyo ebangela ukuba kufuneke ukulungiswa rhoqo.

II. Isithando somlilo esiqhubekayo seGraphitization (Izixhobo eziphuculweyo)

Umgaqo:
Isithando somlilo esiqhubekayo se-graphitization sisebenzisa uyilo lwendawo yobushushu obuguquguqukayo, olwenza ukuba i-petroleum coke ikwazi ukomisa, i-calcination, i-graphitization, kunye nezigaba zokupholisa ngokulandelelana njengoko ihamba kwisithando somlilo, ifezekisa imveliso eqhubekayo. Umongo wayo usekwe ekunciphiseni ixesha lokucubungula ngebhetshi nganye ngokuhamba kwezinto.

Iingenelo:

• Ukusebenza kakuhle kwemveliso: Ngaphandle kokuphazamiseka kombane, izinto zihlala zihamba ngaphakathi kwesithando somlilo, nto leyo enciphisa ixesha lokucubungula ngebhetshi nganye ukuya kwiiyure ezininzi ukuya kwiintsuku.
• Ukusetyenziswa kwamandla aphantsi kakhulu: Ngokuphucula ukusetyenziswa kobushushu nokunciphisa imijikelo yokufudumeza engafunekiyo, ukusetyenziswa kwamandla kwimveliso nganye kuyancitshiswa.
• Umgangatho weMveliso oZinzileyo: Ulawulo lwendawo yobushushu obuguqukayo lunciphisa ubushushu obugqithisileyo okanye ubushushu obungaphantsi kwendawo, nto leyo ephucula ukuhambelana kwemveliso.

Iingxaki:

• Ubunzima Bezixhobo Eziphezulu: Ulawulo oluchanekileyo lwesantya sokuhamba kwezinto, ukusasazwa kwendawo yobushushu, kunye nezinye iiparameter ziyafuneka, nto leyo ebeka umda ophezulu wobugcisa.
• Utyalo-mali oluphezulu lokuqala: Iindleko zokwakha zomgca wemveliso oqhubekayo ziphezulu kunezo zezixhobo zebhatshi zemveli.

III. I-Ultrafine Grinder (Izixhobo eziNcedisayo)

Umgaqo:
I-grinder ye-ultrafine isebenzisa ukungqubana okukhawulezayo, ukucheba, kunye nokukhupha ukuze ityumze i-coke ye-petroleum eyenziwe nge-graphitized ibe ngamasuntswana anobukhulu be-micron (umz., i-200 mesh), ihlangabezana neemfuno zobukhulu bamasuntswana kwizicelo ezithile ezifana nezongezo zerabha.

Iingenelo:

• Ulawulo Oluchanekileyo Lobungakanani Beenxalenye: Ingavelisa iipowders ezicolekileyo kakhulu eziqala kwi-0.001-0.1mm, ezihlangabezana neemfuno zemarike eziphezulu.
• Uyilo oluphantsi lokunxiba: Ukusebenzisa izixhobo ze-alloy eziqinileyo kakhulu xa kusiliwa iihamile kunye neeringi zegiya kwandisa ubomi bezixhobo.
• Ukwenziwa kwezinto ngekhompyutha okuphezulu: Iinkqubo zokwahlulahlula kunye nokuqokelela ezidibeneyo zinciphisa ukungenelela ngesandla, ziphucula uzinzo lwemveliso.

Iingxaki:

• Ukusetyenziswa Kwamandla Okwandayo Ngokucocwa Kobungakanani Beenxalenye: Ukusila ukuya kumanqanaba e-micron kufuna igalelo eliphezulu lamandla, nto leyo enyusa ukusetyenziswa kwamandla kwimveliso yeyunithi.
• Iindleko Eziphezulu Zezixhobo: Izixhobo ze-alloy ze-Superhard kunye neenkqubo zokwahlulahlula ngokuchanekileyo zinegalelo kutyalo-mali lokuqala oluphezulu.

IV. Isithando Somlilo Sokunyibilikisa Isinyithi (Izixhobo Zonyango Lwangaphambi Konyango)

Umgaqo:
Isithando somlilo esibizwa ngokuba yi-calcination siphatha i-petroleum coke eluhlaza malunga ne-1300°C ukususa izinto eziguquguqukayo nokunyusa umxholo wekhabhoni, nto leyo ebonelela ngezinto ezisemgangathweni ophezulu zokwenziwa kwe-graphitization elandelayo. Isiseko saso sisekulawuleni ubushushu be-calcination kunye nexesha lokuthintela ukutsha okugqithisileyo.

Iingenelo:

• Umgangatho wezinto eziluhlaza ophuculweyo: Ukuchithwa kwe-calcination kunciphisa i-volatile matter kwaye kwandisa amandla oomatshini, okwenza i-petroleum coke ifaneleke ngakumbi kwi-graphitization.
• Ukuhambelana Okuqinileyo Kwenkqubo: Ingacubungula i-petroleum coke eluhlaza evela kwimithombo eyahlukeneyo, ivumela ukwahlukahluka kwezinto eziluhlaza.

Iingxaki:

• Ukusetyenziswa kwamandla aphezulu: Ukufudumeza rhoqo ukuze kusetyenziswe i-calcination kumaqondo obushushu aphezulu kwandisa iindleko zamandla.
• Uxinzelelo Olubalulekileyo Kwindalo Esingqongileyo: Ukutsha kwezinto eziguquguqukayo kunokuvelisa ungcoliseko, nto leyo efunekayo (exhasa) iinkqubo zonyango lwegesi yomsila.

V. Iingcebiso zokuthelekisa nokukhetha izixhobo

Iingcebiso zokukhetha:

• Beka phambili isithando sokufakelwa i-graphitization ukuba umgangatho ophezulu wemveliso kunye nozinzo zibaluleke kakhulu, kwaye ubuthathaka beendleko buphantsi.
• Khetha i-furnace ye-graphitization eqhubekayo ukuba ukuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa ukusetyenziswa kwamandla zezona zinto ziphambili.
• I-grinder ye-ultrafine ibaluleke kakhulu xa ijolise kwiimarike zepowder ezinobukhulu obuphezulu be-micron.
• Isithando somlilo se-calcination, njengesixhobo sonyango lwangaphambi konyango, kufuneka silungiselelwe ngokuguquguquka ngokusekelwe kumgangatho wezinto eziluhlaza.
