Ferrosilicon yog ib qho hlau uas feem ntau yog tsim los ntawm silicon thiab hlau, feem ntau muaj li 70% mus rau 75% silicon thiab 25% mus rau 30% hlau. Nws yog ib qho tseem ceeb additive siv nyob rau hauv steel manufacturing thiab lwm yam metallurgical txheej txheem los txhim kho kev ua tau zoo ntawm steel.
Ferrosilicon feem ntau yog tsim los ntawm ore smelting thiab synthesis. Cov hauv qab no yog cov txheej txheem ntau lawm:
Mineral ua thiab crushing: Cov ntaub ntawv tseem ceeb rau ferrosilicon yog silica thiab hlau ore. Cov ores no yog thawj zaug ua tiav los ntawm kev siv txiaj ntsig thiab tom qab ntawd crushed rau hauv cov khoom me me.
Kev kho ua ntej: Ore hais yuav tsum tau kho ua ntej, xws li ziab, preheating, thiab coking, thiaj li yuav yooj yim dua rau hauv cov txheej txheem smelting tom ntej.
Smelting: Cov ore kho ua ntej raug xa mus rau qhov kub kub smelting rauv. Cov feem ntau siv yog hluav taws xob arc rauv los yog blast furnaces. Thaum qhov kub thiab txias, cov hlau thiab silicon hauv cov ore yuav raug txo thiab ua ke los ua ferrosilicon alloy.
Kev hloov kho alloy: Raws li qhov xav tau ntawm cov alloy muaj pes tsawg leeg thiab cov qauv zoo, nws yuav tsim nyog ntxiv lwm cov ntsiab lus alloying lossis ua lwm yam kev kho mob los kho cov muaj pes tsawg leeg ntawm ferrosilicon.
Casting thiab Forming: Molten ferrosilicon alloy yog nchuav rau hauv pwm rau casting, tsim cov duab thiab loj. Qhov no tuaj yeem ua rau hauv daim ntawv ntawm cov blocks, rods, lossis lwm yam duab, nyob ntawm qhov kawg siv.
Txias thiab solidification: Cov cam khwb cia ferrosilicon alloy yuav tsum tau ua kom txias thiab khov kho kom muaj kev ruaj ntseg thiab cov qauv thaum ua thiab siv tom ntej.
Cov saum toj no yog cov txheej txheem ntau lawm ntawm ferrosilicon, tab sis cov txheej txheem tsim khoom tshwj xeeb yuav txawv nyob ntawm cov chaw tsim khoom, cov khoom siv, thiab qib kev tshaj lij.
