Khoom Description
Ferrosilicon yog ib qho khoom siv nrov siv hauv kev tsim khoom ntawm ntau yam khoom siv hlau. Ib qho ntawm ntau hom ferrosilicon yog FeSi72. Cov hlau no feem ntau siv rau hauv cov ntawv thov casting, tshwj xeeb tshaj yog rau kev tsim cov khoom zoo cam khwb cia hlau.
FeSi72 yog ferroalloy uas muaj 72% silicon thiab 28% hlau. Qhov piv ntawm silicon rau hlau muab cov alloy nws cov khoom tshwj xeeb. Cov ntsiab lus ntawm silicon siab ua rau cov hlau tsis muaj zog oxidation, uas pab tiv thaiv kev tsim ntawm impurities thaum lub sij hawm casting txheej txheem.
Tsis tas li ntawd, cov ntsiab lus ntawm silicon siab kuj ua rau kom lub fluidity ntawm cov hlau molten, uas txhim kho cov txheej txheem casting.
Kev siv FeSi72 hauv kev siv casting muaj ntau qhov zoo. Ua ntej, cov alloy muaj peev xwm ua tau zoo heev los txo cov ntsiab lus carbon ntawm cov cam khwb cia hlau. Qhov no yog vim muaj cov ntsiab lus silicon siab, uas ua rau cov pa roj carbon monoxide hauv cov hlau molten los ua silicon carbide. Cov silicon carbide ces precipitates tawm ntawm cov hlau molten thiab raug tshem tawm nrog lub slag, tawm hauv qab ib tug cam khwb cia hlau cov khoom uas muaj ib tug tsawg carbon ntsiab lus.
Qhov thib ob, kev siv FeSi72 hauv kev siv casting tuaj yeem ua rau cov khoom cam khwb cia hlau nrog cov khoom siv kho kom zoo dua qub. Qhov sib ntxiv ntawm cov hlau rau cov hlau molten tuaj yeem ua rau lub zog tensile, hardness, thiab hnav tsis kam ntawm cov khoom kawg. Qhov no yog vim hais tias cov ntsiab lus ntawm silicon siab ntawm cov alloy pab txhim kho lub peev xwm ntawm cov hlau molten kom solidify tusyees, uas ua rau ib yam khoom uas muaj tsawg defects.
Tsis tas li ntawd, FeSi72 kuj tuaj yeem siv los tswj cov qoob loo loj ntawm cov khoom cam khwb cia hlau. Qhov no yog vim hais tias cov silicon nyob rau hauv lub alloy ua raws li ib tug nucleating tus neeg sawv cev, txhawb kev tsim ntawm me me grain loj. Cov qoob loo me me tuaj yeem ua rau cov ductility thiab toughness ntawm cov hlau cam khwb cia, ua rau nws tiv taus ntau dua rau kev tawg thiab lwm yam kev puas tsuaj.
Ntxiv rau nws siv hauv kev siv casting, FeSi72 kuj tseem siv rau hauv kev tsim cov khoom hlau. Cov hlau yog siv hauv steelmaking los txhim kho cov khoom ntawm cov khoom kawg. Piv txwv li, qhov sib ntxiv ntawm FeSi72 rau hlau tuaj yeem ua rau muaj kev nce hauv cov hlau tsis kam tiv thaiv corrosion thiab oxidation, nrog rau nws tag nrho lub zog thiab toughness.
Los xaus, FeSi72 yog ib qho zoo heev ferroalloy nrog ntau qhov zoo rau kev siv hauv kev siv casting. Cov ntsiab lus ntawm silicon siab ntawm cov hlau muaj kev txhim kho corrosion, fluidity thaum lub sij hawm casting txheej txheem, kev tswj zoo ntawm cov nplej loj ntawm cov khoom kawg, txo cov ntsiab lus carbon, thiab cov khoom siv kho tshuab zoo dua. Kev siv cov hlau no hauv kev siv casting thiab steelmaking tsis yog tsuas yog muaj txiaj ntsig tab sis kuj raug nqi. Yog li ntawd, qhov kev thov rau FeSi72 yog ib hnub zuj zus. Nws yog ib qho tseem ceeb hauv kev lag luam niaj hnub no thiab nws qhov tseem ceeb tsis tuaj yeem hais dhau los.
Nyob rau hauv xaus, ferrosilicon yog ib qho tseem ceeb alloy nyob rau hauv niaj hnub kev lag luam, thiab FeSi72 yog ib qho ntawm feem ntau siv hom ferrosilicon. Nws cov khoom ua rau nws yog ib qho tseem ceeb hauv ntau daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv casting thiab steelmaking. Kev siv cov hlau no ua rau cov khoom zoo nrog cov khoom siv kho kom zoo dua qub, ua rau nws muaj txiaj ntsig zoo los txhim kho kev ua haujlwm ntawm cov khoom hlau ferrous. Raws li kev lag luam loj hlob thiab hloov kho tshiab, qhov kev thov rau FeSi72 zoo li yuav loj hlob ntxiv, thiab nws qhov tseem ceeb yuav raug xav hauv txhua lub ces kaum ntawm kev tsim khoom.
