Indlela Yokucwenga Yekhabhoni Ephezulu Yekhabhoni Encibilikisa I-Carbon Ferrochrome ephansi ephansi

I-Chrome ore icwengisa i-carbon ferrochrome ephezulu: lapho kucwengwa i-carbon ferrochrome ephezulu nge-chrome ore, i-slag yokucwenga ine-viscosity enkulu nendawo yokuncibilika ephakeme, futhi izinga lokushisa lenqubo yokuncibilika kufanele libe phezulu. Ngakho-ke, ukusetshenziswa kwamandla kuphezulu, ukuphila komugqa wesithando somlilo kufushane, futhi okuqukethwe kwekhabhoni akulula ukwehla. I-oxygen efutha i-carbon ferrochrome ephezulu inokuphakama okukhulu, njengokukhiqiza okuphezulu, izindleko eziphansi, izinga eliphezulu lokutakula. Njengamanje, indlela yokukhiqiza yendabuko noma indlela yokushisa ye-electro-silicon. Indlela yokushisa ye-Electrosilicon iwukwenza i-alkaline slag esithandweni sikagesi ngaphansi kwesimo se-silicon ku-silicon chromium alloy ukunciphisa i-chromium nama-iron oxides, ukuze kukhiqizwe ikhabhoni ferrochrome ephansi.

Ukucwengwa okufutha umoya-mpilo kwe-carbon ferrochrome ephansi: Indlela yokufutha komoya-mpilo yokucwenga i-carbon ferrochrome ephansi usebenzisa okokusebenza iyisiguquli, ngakho sibizwa ngokuthi indlela yokuguqula. Ngokwezindlela ezehlukene zokuphakelwa komoyampilo, ukuvunguza komoyampilo kungahlukaniswa kube izinhlobo ezine zokuvunguza emaceleni, ukuvuthela phezulu, ukuvunguza okuphansi kanye nokuvunguza kabili phezulu naphansi. Izwe lethu lamukela indlela yokuguqula ephezulu kakhulu. Indlela yokufutha umoya-mpilo iwukuvuthela umoya-mpilo ngqo oketshezini olunekhabhoni ephezulu ye-ferrochrome ukuze ikhishwe i-carburid futhi ikhiqize i-carbon ferrochrome ephansi. Izakhi eziyinhloko ku-carbon ferrochrome ephezulu yi-chromium, i-iron, i-silicon ne-carbon, konke okungaba yi-oxidised. Umsebenzi oyinhloko we-oxidation evuthela i-carbon ferrochrome ephezulu ukukhipha i-carbonise nokugcina i-chromium. Lapho i-oxygen ivuthela oketshezini oluphezulu lwe-carbon ferrochrome, ngoba okuqukethwe kwe-chromium ne-iron kubala ngaphezu kuka-90% yenani eliphelele le-alloy, ngakho-ke i-oxidation yokuqala ye-chromium ne-iron, bese-ke, lawa ma-oxide azokhishwa. i-silicon ku-alloy. Ngenxa ye-oxidation ye-chromium, insimbi ne-silicon, izinga lokushisa lechibi elincibilikile likhuphuka ngokushesha, futhi ukusabela kwe-decarburisation kukhula ngokushesha. Uma izinga lokushisa liphezulu, lithandeka kakhulu ekuphenduleni kwe-decarburisation, futhi lingavimbela ukusabela kwe-oxidation ye-chromium, futhi ukwehla kwekhabhoni ku-alloy kungancipha.
