Ipuleti Lokumboza I-Alumina: Izicelo Eziyinhloko Zokuvikela Nokusebenza Kahle Kwezimboni

Embonini, ukuguguleka, amazinga okushisa aphezulu, kanye nokugqwala kwamakhemikhali kuvame ukunciphisa isikhathi sokuphila kwemishini futhi kuvimbele ukusebenza kahle.ipuleti lokufakwa kwe-alumina—yenziwe nge-Al₂O₃ emsulwa kakhulu futhi eshisiwe ngaphezu kuka-1700°C—ixazulula la maphuzu obuhlungu. Ngobunzima be-Rockwell obungu-80-90 HRA kanye nokumelana nokuguguleka okuphindwe izikhathi ezingu-266 kunokwensimbi ye-manganese, isibe yinto eyinhloko ezimbonini ezibalulekile. Nazi izinhlelo zayo eziyinhloko nokuthi kungani kuyitshalomali oluhlakaniphile lwamabhizinisi oluhlose ukunciphisa izindleko nokukhulisa ukuzinza.

1. Izicelo Zezimboni Eziyinhloko

Amapuleti e-Alumina asebenza kahle kakhulu ezindaweni ezinzima, okwenza abe semqoka ezindaweni lapho imishini ibekezelela khona ukungqubuzana okuqhubekayo, ukushayisana, noma ukushisa okukhulu. Nazi izindlela ezisetshenziswa kakhulu:

Imboni Yamandla Okushisa Namalahle

Ama-conveyor amalahle, ama-pulverizer, kanye namapayipi omlotha ondizayo ezitshalweni zamandla ezishisayo nasezimayini abhekene nokuguguleka okukhulu okuvela ezinhlayiyeni zamalahle. Ama-liners ensimbi endabuko ayaguga ngezinyanga, okubangela isikhathi sokungasebenzi esibizayo. Ama-liners e-Alumina andisa isikhathi sokuphila kwezingxenye ngokufika izikhathi eziyi-10, okwenza iminyaka yokusebenza okuqhubekayo ibe yiminyaka. Ukumelana kwawo nokushisa okuphezulu okungu-1700°C nakho kufaneleka ezinhlelweni zamabhoyila kanye neziteshi zokukhipha umlotha.

Imikhakha Yensimbi, Usimende kanye Nezimayini

Ekukhiqizweni kwensimbi, ama-alumina liner avikela ama-tapholes esithando somlilo, ama-ladle, kanye nemilomo yokuguqula ekugugulekeni kwensimbi encibilikisiwe kanye ne-slag, okwandisa impilo yenkonzo ngo-50%. Ezitshalweni nasezimayini zesimende, zibeka umugqa kuma-chutes, ama-crusher, kanye nemishini yokugaya, zivikela ekushayweni yi-ore kanye ne-clinker. Amapayipi okumba afakwe i-alumina anciphisa ukuguguleka kakhulu, avimbele ukuvuza futhi akhulise ukuphuma kwawo.

Izimboni Zamakhemikhali Nezingilazi

Izitshalo zamakhemikhali zithembele kuma-alumina liners ukuze zithole amaphampu, imikhumbi yokusabela, kanye namapayipi aphatha ama-asidi agqwalisayo, izisekelo, kanye nama-slurry. Zimelana ne-sulfuric acid egxilile kanye nezinye izinto eziqinile, zigwema ukuvuza kanye nokungcola komkhiqizo. Ekwenziweni kwengilazi, ukumelana kwazo nokushisa okungu-1600°C kuzenza zilungele ama-lining esithando, zilondoloze imishini futhi ziqinisekise ikhwalithi yengilazi ehambisanayo.

Ukusetshenziswa Okukhethekile

Ngaphandle kwezimboni eziyinhloko, amapuleti e-alumina ahlanzekile kakhulu (99% Al₂O₃) asebenza kumavesti avikela izinhlamvu zempi (ukuvikelwa kwezinga 3-6) kanye nezimoto ezihlomile—ukwakheka kwazo okulula kuthuthukisa induduzo ngaphandle kokulahlekelwa ukuphepha. Ezindaweni zokukhiqiza izinsimbi, zibeka ama-chutes kanye nama-crucible, zimelana nokuguguleka kwensimbi encibilikisiwe kanye nezinqubo zokubumba ezizinzile.
