Ukukhiqizwa nokusabela

I-Ferrosiliconikhiqizwa ngokunciphisa i-silica noma isihlabathi nge-coke phambi kwensimbi.Imithombo ejwayelekile ye-iron insimbi eyi-scrap noma i-millscale.Ama-Ferrosilicons anokuqukethwe kwe-silicon afika cishe ku-15% enziwa ezithandweni eziqhumayo ezifakwe izitini zomlilo ezine-asidi.Ama-Ferrosilicons anokuqukethwe okuphezulu kwe-silicon enziwa ezithandweni zikagesi ze-arc.Ukwakhiwa okujwayelekile emakethe ama-ferrosilicons ane-silicon engu-15%, 45%, 75%, kanye ne-90%.Okusele kuyinsimbi, cishe u-2% ohlanganisa ezinye izakhi ezifana ne-aluminium ne-calcium.Ukuchichima ngokweqile kwe-silica kusetshenziselwa ukuvimbela ukwakheka kwe-silicon carbide.I-Microsilica iwumkhiqizo owusizo.

I-mineral perryite ifana nei-ferrosilicon, nesakhiwo sayo esithi Fe5Si2.Lapho ithintana namanzi, i-ferrosilicon ingase ikhiqize kancane kancane i-hydrogen.Ukusabela, okusheshiswayo phambi kwesisekelo, kusetshenziselwa ukukhiqizwa kwe-hydrogen.Iphoyinti lokuncibilika kanye nokuminyana kwe-ferrosilicon kuncike kokuqukethwe kwayo kwe-silicon, enezindawo ezimbili ezicishe zibe yi-eutectic, eyodwa eduze ne-Fe2Si neyesibili ehlanganisa uhla lokubhaliwe lwe-FeSi2-FeSi3.

Isebenzisa

I-Ferrosiliconisetshenziswa njengomthombo we-silicon ukunciphisa izinsimbi kuma-oxides azo futhi ikhiphe insimbi namanye ama-alloys ayoni.Lokhu kuvimbela ukulahleka kwekhabhoni ensimbi encibilikisiwe (okubizwa ngokuthi ukuvimbela ukushisa);i-ferromanganese, i-spiegeleisen, i-calcium silicides, nezinye izinto eziningi zisetshenziselwa injongo efanayo.Ingasetshenziswa ukwenza amanye ama-ferroalloys.I-Ferrosilicon iphinde isetshenziselwe ukwenza i-silicon, ukumelana nokugqwala futhi ukumelana nokushisa okuphezulu kwe-silicon alloys, nensimbi ye-silicon yama-electromotor nama-transformer cores.Ekwenziweni kwensimbi eyinsimbi, i-ferrosilicon isetshenziselwa ukujova insimbi ukusheshisa i-graphitization.Ekushiseleni i-arc, i-ferrosilicon ingatholakala kwezinye zezingubo ze-electrode.

I-Ferrosilicon iyisisekelo sokwenziwa kwama-prealloys afana ne-magnesium ferrosilicon (MgFeSi), esetshenziselwa ukukhiqizwa kwe-ductile iron.I-MgFeSi iqukethe i-3-42% ye-magnesium kanye namanani amancane ezinsimbi zomhlaba ezingavamile.I-Ferrosilicon ibalulekile futhi njengesengezo sokuphonsa izinsimbi zokulawula okuqukethwe kokuqala kwe-silicon.

I-Magnesium ferrosilicon iwusizo ekwakhekeni kwamaqhuqhuva, anikeza insimbi eyi-ductile indawo yayo eguquguqukayo.Ngokungafani nensimbi empunga, eyakha ama- graphite flakes, i- ductile iron inamaqhuqhuva e-graphite, noma izimbotshana, ezenza kube nzima nakakhulu ukuqhekeka.

I-Ferrosilicon nayo isetshenziswa enqubweni yePidgeon ukwenza i-magnesium kusuka ku-dolomite.Ukwelashwa kwe-silicon ferrosilicon ephezulu nge-hydrogen chloride kuyisisekelo se-industrial synthesis ye-trichlorosilane.

I-Ferrosilicon iphinde isetshenziswe ngesilinganiso sika-3-3.5% ekwenzeni amashidi wesekethe kazibuthe yama-transformer kagesi.
