1. Needle Coke: Urugero rusanzwe rw'igabanuka rike n'ubucucike bukabije
- Imiterere y'imiterere: Ishinge rya coke rigaragaza imiterere y'imigozi cyangwa ndende ifite imyenge miremire ya elliptical itondetse mu buryo bukurikiranye. Iyi miterere igaragaza ubushobozi bwiza bwo kwiyongera mu gihe cyo gukaraba.
- Kugabanuka kwa Calcination:
- Ingano ya coke ifite igipimo cyo kugabanuka gito, ubusanzwe kiri hagati ya 10% na 20%. Imiterere yayo ya fibre igabanya ubukana binyuze mu gukosora molekile no kuziba imyenge mu gihe cy'ubushyuhe bwinshi, mu gihe imiterere y'imyenge igabanya umwanya wo kugabanuka gukabije, bityo bigabanura igipimo cyo kugabanuka muri rusange.
- Urugero, kuri calcination ya 1300°C, kugabanuka k'ingano ya needle coke bishobora kuba kimwe cya kabiri cy'uko sponge coke imeze, bitewe n'ubushobozi bwayo bwo gukwirakwiza ubushyuhe mu buryo bumwe.
- Ubucucike nyakuri:
- Ingano ya koke ifite ubucucike nyabwo buri hejuru, muri rusange ikaba igera kuri 2.10–2.15 g/cm³. Ibi bigaragaza urwego rwayo rwo hejuru rwa graphitization n'imiterere yayo y'ubucucike bunini, bifitanye isano rya hafi n'imiterere y'ibice bya karuboni mu miterere yayo ya fibre.
- Ubushakashatsi bwerekana ko ubucucike nyakuri bwa needle coke buri hejuru ya 5%–10% ugereranyije na sponge coke, bitewe n’uko hari inenge nke mu miterere yabyo ndetse no kwiyongera cyane kwa karuboni.
2. Sponge Coke: Urugero rusanzwe rw'igabanuka ry'ubucucike n'ubucucike buke nyakuri
- Imiterere y'imiterere: Isosi ya sponge ifite imyenge, isa n'isosi, ifite imyenge idasa neza kandi ikwirakwira, inkuta ntoya kandi zoroshye.
- Kugabanuka kwa Calcination:
- Imboga ya sponge iragabanuka cyane, ubusanzwe iri hagati ya 30% na 50%. Imiterere yayo ifite imyenge idasobanutse ikunze kugwa mu gihe cyo gukaraba bitewe no kurekura kw'imyenge no gushyuha cyane, bigatuma igabanuka cyane.
- Urugero, ku bushyuhe bwa 1200°C, kugabanuka k'umuvuduko wa sponge coke bishobora kurenga 40%, biruta kure cyane ibya needle coke.
- Ubucucike nyakuri:
- Ikinyobwa gisa n'ikinyobwa gifite ubucucike buke cyane, muri rusange kiri hagati ya 1.90 na 2.05 g/cm³. Ibi biterwa n'umubare munini w'imyenge isigaye hamwe n'imiterere idahwitse y'ibice bya karuboni mu miterere yabyo, bigatera inenge nyinshi za kristu.
- Ugereranyije na needle coke, ubucucike nyakuri bwa sponge coke bushobora kuba buri hagati ya 10% na 15%, bitewe no kudakora neza.
3. Shot Coke: Ifite imiterere iri hagati ifite ubucucike buri hagati n'ubucucike nyakuri
- Imiterere y'imiterere: Ishusho y'umuhondo isa n'iy'uruziga cyangwa imeze nk'iy'ibumba, ifite ubuso bukomeye n'imyenge mike, igaragaza imiterere iri hagati y'ishusho y'umuhondo na iy'ibara ry'umuhondo.
- Kugabanuka kwa Calcination:
- Ubusanzwe, icyuma cya shot coke gifite igipimo cyo kugabanuka kiri hagati ya 20% na 30%. Imiterere yacyo y’uruziga igabanuka bitewe n’ubushyuhe bw’ubuso mu gihe cyo gukaraba, ariko imiterere y’imbere mu ruhu igabanya uburebure bw’urumuri.
- Urugero, kuri calcination ya 1250°C, ingano y'igabanuka rya shot coke ishobora kuba 25%, ikagera hagati y'iya needle coke na sponge coke.
- Ubucucike nyakuri:
- Muri rusange, ubucucike bw'ingufu bungana na 2.00 na 2.10 g/cm³. Ubucucike bwayo buruta ubw'ingufu za sponge ariko buri hasi ugereranije na 1.50, bigatuma ubucucike bw'ingufu bungana na 1.50.
- Ubushakashatsi bwerekana ko ubucucike nyakuri bwa shot coke buri hejuru ya 5% ugereranyije n’ubwa sponge coke ariko 3%–5% ugereranyije n’ubwa needle coke.
Isesengura ryimbitse ry'imibanire y'imiterere n'umutungo
- Uburyo bwo kugabanya ubukana:
- Imiterere ya fibrous ya needle coke igabanya inzira zo gucikagurika, ikagabanya umuvuduko wayo wo gucikagurika; imiterere y'imyenge ya sponge coke itera gucikagurika cyane bitewe no kugwa kw'imyenge; imiterere y'uruziga rwa shot coke igera ku gucikagurika ku rugero ruciriritse binyuze mu gukaza ubuso.
- Uburyo nyakuri bw'ubucucike:
- Ubucucike nyakuri bufitanye isano itaziguye no kwiyongera kw'imiterere ya kristu. Imiterere y'urwego rwa karuboni rwashyizweho hamwe n'ubucucike buke bwa nelexle coke bitera ubucucike bwinshi bw'ukuri; imiterere idakora neza n'imyenge isigaye ya sponge coke bigabanya ubucucike nyakuri; shot coke igaragaza imiterere iri hagati.
- Inama ku bijyanye no kunoza imikorere:
- Ku bijyanye n'ikoreshwa risaba kugabanuka guke no kuba ryinshi cyane (urugero, electrodes za grafiti zifite imbaraga nyinshi), ni byiza gukoresha imashini zikoresha icyuma cya elegitoroniki;
- Ku bikoresho bihendutse kandi bifite ubushobozi buke bwo gukora (urugero, lisansi), sponge coke cyangwa shot coke bishobora kuba byiza kurushaho;
- Guhindura ubushyuhe bwa calcination (urugero, hejuru ya 1300°C) n'umuvuduko wo gushyushya (urugero, munsi ya 50°C/min) bishobora kunoza ubucucike nyakuri no kugabanuka kwa needle coke.
