Khoom Description
Ferrosilicon, uas yog cov khoom siv ntau yam ntxiv hauv kev lag luam steel, feem ntau yog siv los ua tus neeg sawv cev txo qis. Nws yog qhov paub tseeb tias kev txo qis yog qhov tseem ceeb tshaj plaws hauv kev tsim cov hlau, thiab txo cov hlau oxide (Fe2O3) rau hlau (Fe) yog cov tshuaj tiv thaiv tseem ceeb tshaj plaws hauv cov txheej txheem. Ferrosilicon, thaum ntxiv rau cov hlau kub sib tov, reacts nrog cov pa oxygen tam sim no hauv cov kua hlau thiab hloov mus rau hauv hlau thiab silicon dioxide (SiO2).
Ferrosilicon muaj ob peb qhov zoo ua tus txo tus neeg sawv cev ntxiv. Ua ntej, nws tau yooj yim muaj thiab yog ib qho txiaj ntsig zoo rau lwm cov tshuaj txo qis xws li coke thiab thee. Thib ob, nws muaj qhov txo qis thiab tuaj yeem txo cov hlau oxide tam sim no hauv cov hlau kub sib tov zoo. Thirdly, nws yog ib qho yooj yim mus use thiab yuav tsum tau dosed kom raug nyob rau hauv lub steelmaking txheej txheem. Thaum kawg, nws tsim cov ntsiab lus tsis tshua muaj leej faj nyob rau hauv cov khoom kawg, yog li txo qhov kev cuam tshuam ib puag ncig ntawm steel ntau lawm.
Ib qho ntawm cov kev siv tseem ceeb ntawm ferrosilicon raws li tus neeg sawv cev txo qis yog nyob rau hauv kev tsim cov hlau stainless. Stainless hlau muaj tsawg kawg yog 10% chromium thiab paub txog nws lub zog siab, tiv thaiv corrosion, thiab kev zoo nkauj. Nyob rau hauv cov txheej txheem steelmaking rau stainless hlau, ferrosilicon yog ntxiv rau cov hlau kub sib tov kom txo tau cov chromium oxide tam sim no nyob rau hauv cov hlau. Chromium yog ib qho ntawm cov hlau nyuaj tshaj plaws los txo, thiab ferrosilicon yog ib qho ntawm ob peb cov neeg ua haujlwm txo qis uas tuaj yeem txo cov chromium oxide rau chromium.
Lwm daim ntawv thov ntawm ferrosilicon raws li ib tug txo tus neeg sawv cev additive yog nyob rau hauv zus tau tej cov silicon hlau. Silicon hlau yog cov khoom siv tseem ceeb hauv kev lag luam hluav taws xob, kev tsim hluav taws xob hnub ci, thiab hauv kev tsim cov txhuas alloys. Ferrosilicon ntxiv rau cov hlau kub sib tov kom txo cov silica (SiO2) tam sim no, yog li tsim cov khoom siv silicon.
Ferrosilicon kuj tseem siv los ua deoxidizer hauv cov txheej txheem steelmaking. Deoxidation yog ib kauj ruam tsim nyog hauv steelmaking kom tshem tawm cov pa oxygen uas tsis xav tau hauv cov kua hlau thaum lub sij hawm melting txheej txheem. Ferrosilicon reacts nrog cov pa oxygen tam sim no hauv cov hlau kub los ntawm kev tsim silicon dioxide, uas ntab mus rau saum npoo ntawm cov hlau molten. Tsis tas li ntawd, silicon ua los ntawm cov tshuaj tiv thaiv nrog oxygen ua ib txheej nyias ntawm cov hlau molten, tiv thaiv kev oxidization ntxiv.
Hauv kev xaus, ferrosilicon yog ib qho tseem ceeb txo tus neeg sawv cev ntxiv hauv kev lag luam steel. Nws qhov kev txo qis qis, kev ua tau zoo, thiab kev cuam tshuam ib puag ncig qis ua rau nws muaj txiaj ntsig zoo rau lwm cov neeg ua haujlwm txo qis. Ferrosilicon yog siv feem ntau hauv kev tsim cov hlau tsis muaj steel thiab silicon hlau, thiab nws kuj yog siv los ua deoxidizer hauv cov txheej txheem steelmaking. Nws ntau daim ntawv thov thiab yooj yim ntawm kev siv tau ua ferrosilicon yog ib qho ntawm cov neeg nyiam tshaj plaws hauv kev lag luam steel.
