Ferrosilicon em i wanpela 'alloy' we ol i wokim long ain na silikon, na em i wanpela bikpela samting we planti manmeri i save yusim insait long wok bilong wokim ol metal.
I. Ol As samting
Em i luk olsem greis-blakpela hap wantaim gutpela kros-seksen na metalik lait, i soim strong na brukbruk.
Wantaim wanpela 'melting point' bilong samting olsem 1300-1400 digri, em i gat strongpela 'reducing properties' na gutpela 'alloying effects'.
Ol i save makim ol 'common gred' long 'silicon content', olsem 75# (72%-80% Si), 80# (78%-85% Si), na 90# (85%-92% Si).
II. As Veliu
Ferrosilicon i save rausim ol pipia bilong oksijen na salfa long ol 'molten steel' na tu i save strongim strong, hatpela, na strong bilong ol ain, na dispela i mekim na ol i kolim em "indastrial vaitamin" bilong wokim ain.
Em i kamap long ol samting olsem silika ston na ain konsentret (o skrap ain) long rot bilong hai-temperature smelting insait long ol lektrik ark oven. Dispela proses i bikpela pinis na planti manmeri i save yusim long skel.
III. Ferrosilicon Production Raw Materials
Silikon Sos:Silika ston em i nambawan samting we i save givim silikon, na i nidim SiO2 konten we i winim o wankain olsem 97% wantaim liklik pipia (aluminium, kalsium, magnesium, na ol narapela).
Ol Raw Materiel we i kam long ain:Ain ore konsentret o skrap ain i save givim ain, we i bung wantaim silikon long kamapim aloi.
Ejen bilong daunim:Ol samting bilong kabon i save daunim silikon long 'quartzite' long bikpela hat. Ol kombinesen we planti i save yusim em olsem 'coke' ('fixed carbon' i winim o wankain olsem 85%) + 'charcoal' (i save strongim 'reaction activity').
Fluorspar:Ol i putim liklik hap (1%-3% bilong olgeta 'raw materials') olsem wanpela 'flux' bilong daunim 'slag melting point', mekim 'slag' i ron gut, na helpim wok bilong rausim 'slag'.
Laim:Ol i putim sapos i gat nid long stretim 'slag alkalinity', daunim ol lus bilong 'silicon volatilization', na strongim 'recovery rates'.
