Ukuqonda Ukupheka Kanzima: Umhlahlandlela Ophelele

Lo mhlahlandlela unikeza incazelo eningiliziwe ye ukupheka kanzima, ehlanganisa izakhiwo zayo, izinhlelo zokusebenza, nezinselele ezihambisana nokusetshenziswa kwayo. Sizohlola umehluko phakathi kwamalahle okupheka aqinile nathambile, singene kunqubo ye ukupheka kanzima, futhi uhlole umthelela wayo ezimbonini ezihlukahlukene. Funda ukuthi ungakhetha kanjani uhlobo olulungile lwamalahle ngezidingo zakho ezithile futhi uthole izixazululo ezifanayo ukupheka kanzima izindaba ezihlobene.

Kuyini I-Hard Coking?

Ukupheka kanzima ibhekisela enqubweni yokukhiqiza i-coke ye-metallurgical kusuka kumalahle a-bituminous aphezulu, aphansi-sulphur. Lolu hlobo lwamalahle, lapho lungaphansi kwamazinga okushisa aphezulu lapho kungekho moya, lubhekana nenqubo ye-pyrolysis, luguquke lube yi-carbon material enamandla, enezimbotshana eyaziwa ngokuthi i-coke. “Ubulukhuni” bubhekisela emandleni angokwenyama kanye nobuqotho besakhiwo se-coke ewumphumela, okubalulekile ekusetshenzisweni kwayo ezithandweni eziqhumayo nezinye izinqubo zensimbi ezinezinga lokushisa eliphezulu. Izinga le-coke lithinta ngokuqondile ukusebenza kahle nokusebenza kwalezi zinqubo. Ukuqonda izici zamalahle omthombo kubalulekile ekukhiqizeni i-coke yekhwalithi ephezulu efanele izicelo ezifunwa kakhulu. Izinto ezinjengokuqukethwe kwamalahle okuguquguqukayo, okuqukethwe komlotha, nesibabule kunethonya kakhulu izici zomkhiqizo wokugcina.

Izakhiwo Zamalahle Ezifanele Ukuphekwa Okuqinile

Akuwona wonke amalahle afanelekile ukupheka kanzima. Amalahle afanelekile anezici ezithile. Lezi zici zibalulekile ekuqinisekiseni ukukhiqizwa kwe-coke ngamandla adingekayo kanye nokusebenza kabusha.

Izici Eziyinhloko:

• Okuqukethwe okuguquguqukayo okuphezulu: Lokhu kuqinisekisa ipulasitiki eyanele ngesikhathi senqubo yokupheka.
• Okuqukethwe kwesibabule esiphansi: Kubalulekile ukunciphisa ukukhishwa kwesibabule kanye nokugcina ikhwalithi yomkhiqizo wokugcina wensimbi.
• Okuqukethwe komlotha okufanelekile: Umlotha omningi ungenza buthaka isakhiwo se-coke.
• I-fluidity efanelekile kanye nezakhiwo zokuvuvuka: Lezi zakhiwo zinquma ukuthungwa namandla kwe-coke.

I-Hard Coking Process

I ukupheka kanzima inqubo ngokuvamile ihilela izigaba eziningana: ukulungiswa kwamalahle, ukushaja, ukupheka, nokucisha i-coke. Amalahle aqale agaywe futhi ahlanganiswe ukuze kuzuzwe izakhiwo ezidingekayo. Le ngxube ibe isifakwa kuhhavini we-coke, lapho ishiselwa khona kuze kufike emazingeni okushisa aphezulu (azungeze u-°C) lapho ungekho umoya. Le nqubo ixosha izinto eziguquguqukayo, ishiye insalela ye-carbon eqinile - i-coke. I-coke ibe isicishwa ukuze iphole ngaphambi kokuba ihanjiswe ukuze isetshenziswe. Ukusebenza kahle kwalolu hlelo kuba nomthelela omkhulu ezindlekweni kanye nekhwalithi yomkhiqizo wokugcina. Amasu okuthuthukisa, njengokuqapha ngokucophelela izinga lokushisa nengcindezi kuyo yonke inqubo, avame ukusetshenziswa.

Izicelo ze-Hard Coke

Ukusetshenziswa okuyinhloko kwe-hard coke kufana ne-ejenti yokunciphisa iziqhumiso zokwenziwa kwe-ayina. Amandla ayo aphezulu kanye ne-porosity kubalulekile ekusekeleni isisindo somthwalo esithandweni somlilo kanye nokwenza lula ukugeleza kwegesi okuphumelelayo. Ngaphezu kwalokho, ukusebenza kabusha kwayo kuqinisekisa ukuncishiswa okusebenzayo kwe-iron ore. Ngokwandayo, ucwaningo luyenziwa kwezinye izinhlelo zokusebenza, ukuhlola amandla alo kwezinye izinqubo ze-metallurgical ezisezingeni eliphezulu lokushisa kanye nezimboni ezithatha ikhabhoni.

Izinselele kanye Nezitayela Zesikhathi esizayo Ekuphekeni Okuqinile

I ukupheka kanzima imboni ibhekene nezinselelo ezimbalwa. Ukuhlangabezana nemithetho eqinile yezemvelo ehlobene nokukhipha isibabule kanye nekhwalithi yomoya kuyinkinga enkulu. Ucwaningo ngobuchwepheshe bokupheka obuhlanzekile nobusebenza kahle buyaqhubeka. Ukwengeza, ukuthola nokufinyelela amalahle ekhwalithi ephezulu kuya ngokuya kuba nzima. Ukuqamba okusha kumasu okuhlanganisa amalahle nezinye izinqubo zokuphekela kubalulekile ukuze kuhlangatshezwane nezidingo zesikhathi esizayo. Ukuthuthukiswa kwezinye izindlela ezisimeme esikhundleni se-coke ekwenzeni insimbi nakho kugxile ocwaningweni olukhulu.

Ukukhetha Ilahle Elilungile Lokupheka Okuqinile

Ukukhetha amalahle afanelekile ukupheka kanzima kubalulekile. Ukuqonda izidingo ezithile zohlelo lwakho lokusebenza kanye nezakhiwo zezinhlobo zamalahle ezihlukene kubalulekile. Lokhu kuhilela ukuhlaziya ngokucophelela izici zekhemikhali nezakhiwo zamalahle, kanye nokucatshangelwa kwezinto ezifana nezindleko nokutholakala. Xhumana nochwepheshe abanolwazi kulo mkhakha ukuze uqinisekise ukukhethwa kwamalahle alungele izidingo zakho.

Ukuze uthole ukwaziswa okwengeziwe nge-coke yekhwalithi ephezulu ye-metallurgical, vakashela I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd. Bangumhlinzeki oholayo we-coke ye-metallurgical neminye imikhiqizo esekwe ku-silicon.
