Indlela yokuSungula yeCarbon Ferrochrome ephezulu yokuNyibilikisa ePhakathi-phantsi kweCarbon Ferrochrome

I-Chrome ore yokucokisa i-carbon ferrochrome ephezulu: xa ucoca i-carbon ferrochrome ephezulu nge-chrome ore, i-slag yokucokisa ine-viscosity enkulu kunye neqondo eliphezulu lokunyibilika, kwaye ubushushu benkqubo yokunyibilikisa kufuneka bube phezulu. Ngoko ke, ukusetyenziswa kwamandla kuphezulu, ubomi belinen yesithando somlilo bufutshane, kwaye umxholo wekhabhoni akulula ukuhla. Ioksijini evuthela i-carbon ferrochrome ephezulu inokuphakama okukhulu, okufana nemveliso ephezulu, ixabiso eliphantsi, izinga eliphezulu lokubuyisela. Okwangoku, indlela yokuvelisa yemveli okanye indlela yokushisa ye-electro-silicon. Indlela yokufudumala ye-Electrosilicon kukwenza i-alkaline slag kwiziko lombane phantsi kwemeko yesilicon kwi-silicon chromium alloy ukunciphisa i-chromium kunye neeoksidi zentsimbi, ukuze kuveliswe i-carbon ferrochrome ephantsi.

Ukuvuthelwa kweoksijini yokusulungekiswa kwe-carbon ferrochrome ephantsi: Indlela yokuvuthela i-oxygen yokucokisa i-carbon ferrochrome ephantsi kusetyenziswa isixhobo sisiguquli, ngoko ibizwa ngokuba yindlela yokuguqula. Ngokweendlela ezahlukeneyo zobonelelo lweoksijini, ukuvuthela kweoksijini kunokohlulwa kube ziindidi ezine zokuvuthela emacaleni, ukuvuthela phezulu, ukuvuthela ezantsi kunye nokuvuthela kabini phezulu nasezantsi. Ilizwe lethu lamkela eyona ndlela iphezulu yokuguqula umoya. Indlela yokuvuthela ioksijini kukuvuthela ioksijini ngokuthe ngqo kulwelo olunekhabhoni ephezulu yeferrochrome ukuyenza idecarburised kwaye ivelise ikhabhoni ephantsi yeferrochrome. Izinto eziphambili kwi-carbon ferrochrome ephezulu yi-chromium, isinyithi, i-silicon kunye nekhabhoni, enokuthi yonke i-oxidised. Owona msebenzi uphambili we-oxidation uvuthela i-carbon ferrochrome ephezulu kuku-decarbonise kunye nokugcina ichromium. Xa ioksijini ivuthelwe kulwelo lwe-ferrochrome ephezulu yekhabhoni, kuba umxholo wechromium kunye ne-akhawunti yentsimbi ngaphezu kwe-90% yexabiso lilonke le-alloy, ngoko ke, i-oxidation yokuqala yechromium kunye nentsimbi, kwaye ke, ezi oxides ziya kuba oxidised off. i-silicon kwi-alloy. Ngenxa ye-oxidation ye-chromium, isinyithi kunye ne-silicon, iqondo lobushushu lechibi elinyibilikisiweyo landa ngokukhawuleza, kwaye ukusabela kwe-decarburisation kukhula ngokukhawuleza. Ukuphakama kweqondo lobushushu, kokukhona kuthandeka ngakumbi kwimpendulo ye-decarburisation, kwaye inokuthintela ukusabela kwe-oxidation yechromium, kwaye okukhona i-carbon esezantsi kwi-alloy inokuncipha.
