Khoom Description
Ntawm ntau cov ntaub ntawv alloy,ferrosiliconundoubtedly occupies ib qho tseem ceeb txoj hauj lwm.
Silicon hlau, hauv cov ntsiab lus yooj yim, yog cov hlau alloy uas muaj hlau thiab silicon. Nws txoj kev yug me nyuam tsis yog qhov xwm txheej, tab sis ua tib zoo ua tib zoo los ntawm cov txheej txheem thev naus laus zis tshwj xeeb.
Cov txheej txheem tsim khoom siv coke, steel shavings, quartz (los yog silica) ua cov ntaub ntawv tseem ceeb, thiab siv lub tshuab hluav taws xob smelting kom tau txais qhov tshwj xeeb hlau silicon alloy.
Ib qho laj thawj tseem ceeb vim li cas ferrosilicon muaj ntau yam kev siv hauv thaj chaw xws li steelmaking yog nws cov khoom siv tshuaj. Vim qhov yooj yim synthesis ntawm silicon dioxide los ntawm silicon thiab oxygen, ferrosilicon tau dhau los ua ib qho zoo heev deoxidizer hauv steelmaking. Thaum ferrosilicon ntxiv rau cov hlau, nws tuaj yeem hnov mob sai sai nrog cov pa oxygen, ua ke kom ua tiav deoxygenation.
Tsis tas li ntawd xwb, tseem muaj lub luag haujlwm tseem ceeb ntxiv hauv cov txheej txheem deoxidation no. Ntawd yog, cov cua kub ntau yuav raug tso tawm thaum lub sijhawm SiO2 tiam. Qhov no tsis yog ib qho yooj yim tso tawm ntawm tshav kub, nws muaj ntau lub ntsiab lus hauv cov txheej txheem steelmaking. Ntawm qhov tod tes, qhov cua sov no tuaj yeem ua lub luag haujlwm zoo hauv kev nce qhov kub ntawm cov hlau molten thaum deoxidating. Qhov nce hauv molten steel kub muaj qhov cuam tshuam tseem ceeb ntawm kev ua tiav ntawm steelmaking thiab zoo ntawm cov hlau. Qhov kub siab dua pab ntau yam kev cuam tshuam hauv cov hlau molten kom tshwm sim ntau dua, txhawb kev tshem tawm cov impurities thiab homogenization ntawm hlau.
siv nyob rau hauv steelmaking txheej txheem
Tsis tas li ntawd, tus yam ntxwv ntawm ferrosilicon no kuj ua rau nws hloov tsis tau hauv qee cov txheej txheem steelmaking. Tus nqi thiab kev siv ntawm ferrosilicon tuaj yeem sib txawv nyob ntawm qhov sib txawv steelmaking txoj kev thiab qib steel, tab sis nyob rau hauv txhua rooj plaub, ferrosilicon ntxiv ib qho tseem ceeb pab rau cov txheej txheem steelmaking nrog nws cov khoom tshwj xeeb.
Hauv kev siv tswv yim, kev tswj xyuas zoo thiab muaj pes tsawg leeg ntawm ferrosilicon kuj tseem ceeb heev. Cov khoom zoo ferrosilicon yuav tsum muaj qhov tsim nyog silicon thiab hlau cov ntsiab lus sib piv, nrog rau cov ntsiab lus qis dua. Tsuas yog nyob rau hauv txoj kev no nws tuaj yeem ua kom nws qhov kev ua tau zoo hauv cov txheej txheem steelmaking.
Nrog rau kev txhim kho tas mus li thiab kev vam meej ntawm kev lag luam steel, qhov kev thov rau ferrosilicon kuj tseem nce ntxiv. Cov kws tshawb fawb thiab cov tuam txhab tsim khoom tseem niaj hnub siv zog los tshawb nrhiav ntau dua, tus phooj ywg zoo ib puag ncig, thiab txuag hluav taws xob ferrosilicon ntau lawm thev naus laus zis kom tau raws li kev lag luam loj hlob.
