Txhawm rau txhim kho cov deoxidation efficiency ntawmsilicon slagnyob rau hauv tus txheej txheem ntawmsteelmaking deoxidation, peb tuaj yeem pib los ntawm optimizing qhov zoo ntawm silicon slag nws tus kheej, kev txhim kho cov txheej txheem steelmaking thiab tsim nyog txuam lwm yam khoom. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
1. Tswj qhov zoo ntawm silicon slag
Ua kom cov ntsiab lus silicon:Silicon yog lub ntsiab tseem ceeb rau silicon slag deoxidation, thiab sim siv silicon slag nrog cov ntsiab lus siab silicon. Los ntawm optimizing cov txheej txheem ntawm silicon slag, xws li tswj qhov kub thiab txias, raw khoom piv, thiab lwm yam., ua kom cov ntsiab lus ntawm elemental silicon hauv silicon slag tuaj yeem txhim kho nws lub peev xwm deoxidation. Piv txwv li, nyob rau hauv tus txheej txheem ntawmsilicon hlausmelting, cov tshuaj tiv thaiv nyob rau hauv lub cub tawg yog precisely tswj los txhawb lub tiam thiab enrichment ntawm silicon, li no tau txais silicon slag nrog ib tug siab silicon ntsiab lus.
Txo cov ntsiab lus impurity:nruj me ntsis tswj cov ntsiab lus ntawm impurity ntsiab xws li sulfur, phosphorus, thiab carbon nyob rau hauv silicon slag. Cov impurities no tsis tsuas yog muaj kev cuam tshuam tsis zoo rau cov hlau zoo, tab sis kuj tseem tuaj yeem haus ib feem ntawm silicon thiab txo cov deoxidation efficiency ntawm silicon slag. Los ntawm ua ntej - kho silicon slag, xws li sib nqus sib nqus, flotation thiab lwm yam kev tshem tawm impurities, purity thiab deoxidation nyhuv ntawm silicon slag tuaj yeem txhim kho.
2. Txhim kho txoj kev ntxiv
Tsim nyog sijhawm ntxiv:Raws li cov yam ntxwv ntawm cov txheej txheem steelmaking, xaiv lub sijhawm tsim nyog ntxiv silicon slag. Feem ntau hais lus, ntxiv silicon slag ntawm theem thaum cov pa oxygen cov ntsiab lus ntawm cov hlau molten siab tuaj yeem ua rau nws ua rau muaj oxygen. Piv txwv li, ntxiv silicon slag nyob rau hauv lub lig tshuab theem ntawm converter steelmaking los yog lig oxidation theem ntawm hluav taws xob rauv steelmaking, thaum cov pa oxygen cov ntsiab lus nyob rau hauv lub molten steel yog kuj siab, yog conducive rau deoxidation nyhuv ntawm silicon slag.
Uniform dispersion:Siv cov cuab yeej pub noj kom tsim nyog thiab cov txheej txheem los xyuas kom meej tias cov silicon slag tuaj yeem sib npaug sib npaug hauv cov hlau molten. Piv txwv li, siv lub tshuab tshuab los txau silicon slag rau hauv cov hlau molten hauv daim ntawv ntawm cov khoom zoo tuaj yeem ua rau thaj chaw sib cuag ntawm silicon slag thiab molten steel, ua kom cov tshuaj tiv thaiv deoxidation, thiab txhim kho cov deoxidation efficiency.
3. Tswj molten steel tej yam kev mob
Kev tswj qhov kub thiab txias:Khaws ib qho chaw zoo molten steel kub. Yog tias qhov kub thiab txias dhau lawm, cov silicon hauv silicon slag yuav volatilize ntau dhau, txo nws cov nqi siv; Yog tias qhov ntsuas kub qis dhau, nws yuav cuam tshuam rau cov tshuaj tiv thaiv ntawm silicon thiab oxygen. Raws li cov txheej txheem steelmaking tshwj xeeb, kev tswj xyuas qhov kub ntawm cov hlau molten nyob rau hauv ib qho kev tsim nyog tuaj yeem txhim kho cov deoxidation efficiency ntawm silicon slag.
Kev ua haujlwm stirring:Ntxiv dag zog rau lub nplawm ntawm cov hlau molten. Los ntawm electromagnetic stirring, mechanical stirring thiab lwm txoj kev, cov hlau molten tuaj yeem ua tiav los txhawb kev sib cuag thiab cov tshuaj tiv thaiv ntawm silicon slag thiab oxygen hauv cov hlau molten. Kev sib xyaw kuj tuaj yeem ua rau cov khoom tsim tawm deoxidation (xws li silicon dioxide, thiab lwm yam) ntab thiab tso tawm sai li sai tau, txo nws cov seem hauv cov hlau molten, thiab txhim kho cov nyhuv deoxidation.
4. Tsim nyog ua ke ntawm lwm yam deoxidizers
Ua ke nrog muaj zog deoxidizers:Siv silicon slag nrog qee qhov muaj zog deoxidizers (xws li txhuas, calcium, thiab lwm yam). Aluminium thiab calcium muaj zog deoxidation muaj peev xwm. Ua ntej, ntxiv ib qho me me ntawm cov deoxidizer muaj zog kom txo qis cov ntsiab lus ntawm cov pa oxygen ntawm cov hlau molten, thiab tom qab ntawd ntxiv silicon slag ntxiv rau deoxidize thiab kho qhov muaj pes tsawg leeg ntawm cov hlau molten. Txoj kev sib xyaw deoxidation no tuaj yeem muab kev ua si tag nrho rau qhov zoo ntawm cov deoxidizers sib txawv thiab txhim kho tag nrho cov deoxidation efficiency.
Composite deoxidizer:Tsim thiab siv cov khoom sib xyaw deoxidizers raws li silicon slag, thiab ntxiv qee cov ntsiab lus lossis cov khoom sib txuas uas muaj txiaj ntsig zoo rau deoxidation thiab txhim kho cov hlau molten zoo, xws li magnesium, barium, thiab lwm yam, rau silicon slag. Cov ntsiab lus no tuaj yeem ua ke nrog silicon slag los txhim kho cov nyhuv deoxidation, thaum tseem txhim kho kev ua haujlwm ntawm slag thiab txhawb kev tawm ntawm cov khoom deoxidation.
5. Tiag - sijhawm saib xyuas thiab hloov kho
Online nrhiav tau:Siv cov thev naus laus zis tshawb nrhiav, xws li kev tsom xam spectral, oxygen cov ntsiab lus ntsuas, thiab lwm yam. Kho tus nqi thiab lub sij hawm ntawm silicon slag ntxiv nyob rau hauv lub sij hawm raws li qhov kev xeem tau los xyuas kom meej tswj cov txheej txheem deoxidation.
Cov ntaub ntawv tsom xam thiab optimization:Sau thiab txheeb xyuas cov ntaub ntawv hauv cov txheej txheem steelmaking, thiab sau cov kev cai thiab kev paub ntawm silicon slag deoxidation. Los ntawm kev txheeb xyuas cov ntaub ntawv, tshawb xyuas cov ntsiab lus tseem ceeb cuam tshuam rau kev ua haujlwm ntawm deoxidation, thiab ua tiav cov txheej txheem kev ua kom zoo thiab txhim kho kom tsis tu ncua txhim kho deoxidation efficiency ntawm silicon slag.
