Ferrosilicon alloy la bu boole wen ak silisium, ñu koy jëfandikoo bu baax ci liggéeyum metalurgie.
I. Màndarga yu am solo
Dafay nuru ay gënn yu ñuul yu dóomu taal, am section croix bu nooy ak lustre metalik, di wane dëgër ak yàqu-yàqu.
Ak point de fusion bu tollu ci 1300-1400 degre, amna doole wàññiku ak effet alloying yu baax.
Grade yiñ gëna xam ñu ngi leen di xaaj ci limu silisium, lu ci melni 75# (72%-80% Si), 80# (78%-85% Si), ak 90# (85%-92% Si).
II. Valeur core
Ferrosilicon dafay dindi bu baax oxygen ak sulfur yi ci asiye buy seey, ci noonu muy gëna dëgëral, dëgër, ak baña yàqu ci macceer metalik yi, moo tax ñu tuddee ko "vitamine usine" ngir defar asiye.
Ñu ngi koy defaree ci macceer yu bees yu melni xeer silice ak concentré wen (wala asiye buñ jële) jaare ko ci fuur à arc électrique ci tàngoor wu kawe. Doxalin bi matna te ñu ngi koy jëfandikoo ci anam wu yaatu.
III. Matériel premier de production de ferrosilicon
Ibnu silisium:Xeer silisium mooy gëna am solo biy joxe silisium, te dafay laaj SiO2 bu ëpp wala bu tollu ci 97% ak ay mbalit yu néew (aluminium, kalsium, magnesium, ak ñoom seen).
Matériel premier biy joge ci wen:Concentré de minerail de fer wala des déchets de wen mooy joxe wen, biy boole ak silisium ngir sos alloy bi.
Agent buy wàññi:Macceer karbon yi ñooy njëkka wàññi silisium ci quartzite ci tàngoor wu metti. Njaxas yiñ gëna xam ñooy coke (carbon fixe bu ëpp wala tollu ci 85%) + këriñ (dafay gëna dooleel reaction bi).
Fluorspat:Yokk ci limu tuuti (1%-3% ci macceer premier bi) muy flux ngir wàññi point de fusion slag, gëna yombal fluidité slag, ak yombal dindi slag.
Lime:Yokk nañu ko ci anam wu war ngir yamale alkalinite slag, wàññi perte volatilisation silisium, ak yokk taxum recuperation.
