Ukukhiqizwa Ukusingathwa yokusansimbi

Omunye imikhakha eyinhloko umnotfo yokusansimbi. Inikeza impahla eluhlaza, nezinye eziningi izimboni. Idoyelo futhi izinsimbi non-ayoni kudingeka cishe kuyo yonke indawo. Futhi amanani lezi izinto zokusetshenziswa zikhulisa nsuku zonke. Amandla amanani, yebo, abe nomthelela obonakalayo intengo yemikhiqizo steel. Kodwa indima ebalulekile ekwakhekeni nokukhiqizwa kwezincwadi imfucuza udlala amanani.

Futhi kule yokusansimbi ka yabo lilikhulu. Akulesi izindawo ezinkulu futhi ngaleyo ndlela ukungcolisa umoya compounds ezinobuthi, amanzi nomhlabathi. Futhi ngesikhathi esifanayo ku izindleko zendawo yokuhlala yabo, isitoreji kanye zokuhamba we elikhulu ekwehliseni izindleko zokukhiqiza wamabhizinisi Metallurgical. Kodwa lokhu kudla aqukethe eziningi izakhi engasetshenziswa njengoba izinto zokusetshenziswa yesibili. Futhi lapho indlela yenkosi, ezifana imfucumfucu Metallurgical kungenziwa yaphenduka umthombo engenayo.

Lezi imfucumfucu umphumela we sokuncibilikisa steel, yensimbi waphonsa noma ferroalloys. Futhi okuqukethwe izingxenye amaminerali ezahlukene, okungabandakanya yensimbi, kungase kube ephakeme kuzo ngisho kuka ku imikhando zemvelo efanayo. Futhi ngenxa cwaningo enganele isakhiwo nezakhiwo sludges kunenkinga nge yokusetshenziswa kabusha yabo.

Thola okungenani slag steelmaking. Lezi ukukhiqizwa udoti kabusha e eziningi Izigayo steel namafektri ibe slag lufinyelele ezingeni eliphezulu. Ngenxa yale njongo "ezomile" imikhiqizo kazibuthe ngokwahlukana etholwe emva okubuhlungu slag. Umkhiqizo ewusizo etholwe emva le ndlela yokwelapha, amawolintshi igazi kubhekwe metal emikhulu futhi lokubolekwa bensimbi Silica ingilazi. Iron-ahlanganiswe slag Ukwakheka kuyinto kangako. Futhi ngenxa nokunonophala ngesikhathi izitshalo Sinter zamathani slag ekhiqizwa mayelana 40 kg metal. Imikhiqizo asele imfucuza, aqukethe amabala amancane kuphela noma yensimbi oxide kufakwa ikhaba.

Kodwa kukhona ubuchwepheshe letisebentisekako kwandzisa lwati we steel slag. Ngosizo lezi imfucumfucu bengathola imikhiqizo ezintathu. Eyokuqala umkhiqizo metal. Kungaba mayelana 10% of the mass slag. Kuyinto, ngaphandle metallic yensimbi, iqukethe ukungcola okuncane ingilazi, silicates futhi carbonates. Wakhe briquetted wathunyelwa smelter yesibili. Owesibili lime iron oxide umkhiqizo. Kumayelana 22% wezindleko. Iron kulo mkhiqizo kancane. Ngokwengxenye enkulu, liphethe namaminerali ahlukahlukene. Lokhu wustite, magnetite, maghemit, goethite, hematite, hydrated umcako, yensimbi ne-calcium carbonates, kanye magnesium calcium ferrites. Lo mkhiqizo kungasetshenziswa njengendlela izinga okusezingeni feed impahla ekukhiqizeni yensimbi Sinter fluxed. Futhi abaseleyo, okuyinto mayelana 68% ewela Silica umkhiqizo. ingxenye yayo main siqukethe namaminerali: silicates, spinels, tridymite, ingilazi silicate nemikhiqizo lime hydration. Le mikhiqizo imfucuza futhi awulona ize. umkhiqizo silicate isetshenziswa ngokuyinhloko ukwakhiwa, usimende noma eminye imikhiqizo cementitious.

Ungase futhi uthathe ukukhiqizwa slag ferromanganese, aqukethe izakhi eziningi ezibalulekile. Lokhu amawolintshi okusansimbi egazini ferromanganese kanye metallic, silicates, hydroxides, oxides lokubolekwa, manganese nensimbi carbonates, ingilazi silicate, kanye nemikhiqizo ye crystallization yayo. Ososayensi baye basungula indlela lapho ukuziphatha ezomile adonsela phansi lokuhlushwa lezi ubuthi. Ngenxa yalokho lezi imfucumfucu unike amandla imikhiqizo ezintathu.

Eyokuqala yalezi kakhulu okusansimbi manganese ukugxilisa ingqondo. Uyaca ingqikithi slag kungaba uvuke kuya 17%. Lo mkhiqizo iqukethe izingxenye kazibuthe kanye non-magnetic yensimbi, manganese, Cohen yensimbi kanye Alloys ahlukahlukene nge okuqukethwe ngama-manganese nensimbi obuhlukahlukene, futhi oxides yabo futhi hydroxides. Sebenzisa Lo mkhiqizo kungaba ukwenziwa ferromanganese.

Umkhiqizo yesibili i-isihlabathi silicate. Half of the Imininingwane slag isisindo ewela kuye. isihlabathi silicate bahlanganisa ikakhulu asebenza ngebhethri, cristobalite, tridymite, ingilazi kanye silicates. Kusukela ke ungakwazi ukukhiqiza silicomanganese noma esisebenzisa njengophawu yokwakha.

Labo abasele abanga-33% livela othulini ubumba-carbonate. It yakhiwa silicates fake ihlukaniswe, carbonates, ingilazi namanye amaminerali. Lokhu uthuli isetshenziselwa ukukhiqiza usimende. Akhona namanye amaningi yalolu hlobo udoti, okuyinto kungabazuzisa kanjani abantu.
