- Waxaan si sharaf leh u daahfurnay mid cusubGaraafyada Kaarboon Crucibleskaas oo bedelaya garaafyada dibadda laga keeno iyo birta isku dhafan. Alaabtani waxay leedahay sifooyinka soo socda:
- Waxqabadka kharashka ee tanGaraafyada Kaarboon Crucibleswaa in ka badan 50% ka sarreeya alaabta ajnabiga ah ee isku midka ah, tayada waa 3-5 jeer ka badan alaabta gudaha.
- TaniGaraafyada Kaarboon CruciblesLeh waxqabadka kulaylka wareejinta heer sare ah, oo la barbardhigi karo birta isku dhafan. Hufnaanta kulaylka sare, waxay badbaadin kartaa ilaa 1/3 tamar.
- Cimrigeeda oo dheeraaday (in ka badan saddex bilood) waxay yaraynaysaa wakhtiga dhimista. Waxay ka hortagtaa oksaydhka iyo daxalka.
- Alaabta waa sahlan tahay in la isticmaalo waxayna u baahan tahay hawl yar oo ay sameeyaan shaqaaluhu. Kaliya engegan si aad u codsato, looma baahna buraash ama dahaar, looma baahna kafeeye aluminium ama shubid.
- Sida loo sameeyo caaryada graphite, maxay yihiin hababka kala duwan ee naqshadaynta ee caaryada graphite? Aynu ka wada hadalno arrintanMustaqbalka WenzhouoCo., Ltd.
- Alaabta garaafyada waxaa ka mid ah electrodes graphitized, anodes graphitized,
baloogyada garaafyada, nadiif-sare, adag-adkay, iyo garaafka cufnaanta sare.
-Waxyaabaha ugu muhiimsan ee alaabta noocan ah waa petroleum coke ama pitch coke, kaas oo lagu sameeyo daawaynta kulaylka sare ee ka sarreeya 200 ℃ si loogu beddelo kaarboon amorphous graphite. Astaamaha ugu muhiimsan ee alaabta garaafyada ah waa C> 99%, ash <0.5%; koronto iyo kulayl aad u fiican; iyo iska caabin daxalka sare. Habka wax-soo-saarku waa mid adag oo dheer, badanaa wuxuu qaataa 40-60 maalmood.
- Alaabooyinka warshadda kaarboon waxa ay tilmaamayaan meelaha banaan ee la isticmaali karo isla markiiba ka dib marka la shido 1300°C. Alaabooyinkan waxaa loo qaybin karaa alaabada warshadda kaarboon ee dambaska hoose ee leh C>99% iyo alaabada warshadda karbon ee dambaska oo leh C>90%. Wareegga wax-soo-saarku inta badan waa 30 maalmood.
Xabagta ganacsiga macnaheedu waa badeecad la helay iyadoo si isku mid ah loogu qaso dhuxusha ololka dheer ee firidhsan iyo walxaha kookaha oo la isku dhejiyo, kuleyliya oo la qaso, lagana dhigo qaybo yaryar ama weel ku hoos jira uumi kulul oo aan la cadaadin ama kulayl kale. Alaabooyinkani waxay leeyihiin laba adeegsi oo muhiim ah: sida koronto-dubida joogtada ah iyo sida isku xidhka iyo shaabadeynta ee lagu dhejiyo blocks kaarboon. Habka wax soo saarka ee saxarka ganacsiga waa mid sahlan, wareegga wax soo saarka waa gaaban yahay, kharashkuna waa yar yahay.
- Electrodes graphitized waxaa loo isticmaalaa sida walxaha korantada warshadaha dhalada korontada si ay u dhalaaliyaan biraha kala duwan ee carbon, biraha non-ferrous, biraha dhif iyo biraha kale ee aan biraha. Electrodes-ka graphite waxa kale oo loo isticmaalaa dhalaaliyeyaasha qalabka wax lagu gooyo karbidhida sibidhka iyo soosaarka tuubooyinka dhalada quartz. Garaafyada korantada bannaan waxaa lagu shiidi karaa noocyo kala duwan oo tuubooyinka garaafyada iyo qolofyada garaafka.
- Garaafka saafiga ah waxaa lagu daaweeyaa kiimiko, waxaa lagu dhaqaa biyo, waxaana lagu bararaa heerkul sare si loo sameeyo walxaha garaafka fidsan ee dabacsan. Qalabkan tayada sare leh waxaa loo isticmaali karaa in lagu soo saaro alaabooyin kala duwan, sida warqad graphite, kartoon graphite, tube graphite, groove graphite, usha graphite, iwm. Si taas loo gaaro, habka sameynta ayaa loo baahan yahay, taas oo ah, isticmaalka farsamada qalab lagu soo saaro oo lagu farsameeyo alaabta garaafyada ee tilmaamo, qaabab, iyo cabbiro kala duwan. Waqtigan xaadirka ah, waxaa inta badan jira saddex hab oo samaynta: duubista samaynta, samaynta saxafada iyo samaynta extrusion.
