Khoom Description
Steelmaking thiab casting yog cov txheej txheem tseem ceeb hauv kev tsim khoom. Txhawm rau tsim cov hlau zoo, ntau yam ntsiab lus thiab cov alloys yog siv. Ferrosilicon yog cov hlau zoo li no uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau thiab casting txheej txheem.
Ferrosilicon yog ferro-alloy uas muaj hlau thiab silicon, nrog silicon cov ntsiab lus ntawm 15% mus rau 90%. Nws yog feem ntau siv los ua deoxidizer, vim nws nkag siab nrog cov pa oxygen ntxiv hauv cov hlau molten los ua silicon dioxide, uas yog insoluble hauv cov hlau molten thiab ntab rau saum npoo. Qhov no ua kom cov hlau tsim tau zoo thiab muaj cov khoom xav tau.
Ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying los txhim kho cov khoom siv ntawm cov hlau. Nws tuaj yeem ua rau kom muaj zog thiab tensile lub zog ntawm cov hlau, uas ua rau nws zoo tagnrho rau siv hauv kev tsim kho, tsheb, thiab lwm yam lag luam. Qhov sib ntxiv ntawm ferrosilicon nyob rau hauv cov txheej txheem steelmaking kuj txhim kho lub machinability thiab weldability ntawm cov hlau.
Hauv cov txheej txheem casting, ferrosilicon plays lub luag haujlwm tseem ceeb hauv kev tsim cov khoom zoo. Nws yog siv los txo cov ntsiab lus carbon hauv cam khwb cia hlau thiab nce cov ntsiab lus silicon, uas txhim kho lub zog, ductility, thiab corrosion kuj ntawm cov castings. Kev siv cov ferrosilicon hauv casting kuj txo qhov kev pheej hmoo ntawm qhov tsis xws luag, xws li porosity thiab tawg, uas tuaj yeem cuam tshuam rau kev ncaj ncees ntawm casting.
Ib qho ntawm feem ntau siv qib ntawm ferrosilicon hauv steelmaking thiab casting yog 72-75 ferrosilicon. Cov qib no muaj cov ntsiab lus silicon ntawm 72% mus rau 75%, ua rau nws zoo tagnrho rau kev siv cov hlau zoo. Nws muab cov khoom deoxidizing zoo heev thiab txhim kho cov khoom siv ntawm cov hlau, ua rau nws muaj zog, ruaj, thiab tiv taus hnav thiab tsim kua muag.
Zuag qhia tag nrho, ferrosilicon yog ib qho tseem ceeb hauv cov txheej txheem steelmaking thiab casting. Nws siv tsis tau tsuas yog txhim kho qhov zoo ntawm cov khoom tsim, tab sis kuj txhim kho cov efficiency thiab nqi-effectiveness ntawm cov txheej txheem tsim. Nrog rau qhov kev thov ntau ntxiv rau cov hlau zoo hauv ntau qhov kev lag luam, kev siv ferrosilicon zoo li yuav loj hlob ntxiv rau xyoo tom ntej.
Hauv kev xaus, kev siv ferrosilicon hauv steelmaking thiab casting tau hloov pauv kev lag luam tsim khoom. Cov alloy tau pab txhawb kev tsim cov hlau zoo, txhim kho nws cov khoom siv kho tshuab, lub cev, thiab tshuaj lom neeg. Nws yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom thiab tau ua pov thawj tias muaj txiaj ntsig zoo hauv ntau yam kev lag luam. Raws li kev lag luam kev lag luam txuas ntxiv mus, lub luag haujlwm ntawm ferrosilicon tau dhau los ua qhov tseem ceeb, thiab nws txoj kev siv yuav txuas ntxiv mus ntxiv.
