Cov laj thawj tseem ceeb ntawm kev ntxiv ferrosilicon hauv cov txheej txheem steelmaking yog raws li hauv qab no:
Cov khoom siv hlau: Ferrosilicon yog cov khoom siv hlau uas muaj silicon thiab hlau. Ntxiv ferrosilicon tuaj yeem ua kom paub cov ntsiab lus ntawm silicon thiab hlau rau hauv cov hlau. Silicon yog ib qho zoo deoxidizer uas tuaj yeem hnov mob nrog oxygen los tsim silicon dioxide thiab tshem tawm cov pa tawm ntawm cov hlau molten, yog li txo cov pa oxygen hauv cov hlau thiab txo cov qib oxidation. Nyob rau tib lub sijhawm, silicon tuaj yeem txhim kho cov dej ntws thiab dej ntawm cov hlau molten, uas yog qhov zoo rau cov txheej txheem pouring thiab solidification ntawm molten steel.
Tshem tawm cov impurities: Silicon hauv ferrosilicon tuaj yeem tsim cov tshuaj tsis haum nrog cov khoom tsis zoo xws li phosphorus thiab sulfur, txhawb kev sib cais ntawm cov impurities los ntawm cov hlau molten thiab purifying nws. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm converter steelmaking, ntxiv ib qho tsim nyog tus nqi ntawm ferrosilicon tuaj yeem txo cov phosphorus cov ntsiab lus hauv cov hlau molten.
Kho cov alloy muaj pes tsawg leeg: Cov ntsiab lus hlau hauv ferrosilicon kuj tuaj yeem kho qhov muaj pes tsawg leeg ntawm cov hlau molten. Hlau muaj qee yam cuam tshuam rau lub zog thiab hardness ntawm steel. Los ntawm kev ntxiv ferrosilicon, cov ntsiab lus hlau hauv molten steel tuaj yeem tswj tau thiab hloov kho kom tau raws li cov qib steel tshwj xeeb thiab cov ntawv thov.
Nws yuav tsum raug sau tseg tias tus nqi thiab lub sijhawm ntawm kev ntxiv ferrosilicon yuav tsum tau txiav txim siab raws li cov txheej txheem steelmaking tshwj xeeb thiab qib steel yuav tsum tau ua. Hauv cov txheej txheem steelmaking, kev tswj xyuas meej ntawm qhov sib ntxiv ntawm ferrosilicon tuaj yeem txhim kho qhov zoo ntawm cov hlau molten, txhim kho nws cov khoom, thiab ua tau raws li cov khoom siv tshwj xeeb.
