Imveliso kunye neempendulo

Ferrosiliconiveliswa ngokunciphisa i-silica okanye isanti ngecoke phambi kwentsimbi.Imithombo eqhelekileyo yentsimbi zintsimbi ezilahliweyo okanye i-millscale.IiFerrosilicons ezinomxholo we-silicon ukuya kuthi ga kwi-15% zenziwe kwiziko eliqhumayo elifakwe ngezitena zomlilo we-asidi.IiFerrosilicons ezinomxholo ophezulu we-silicon zenziwe kwi-oven arc yombane.Ukuqulunqwa okuqhelekileyo kwimarike yi-ferrosilicons kunye ne-15%, i-45%, i-75%, kunye ne-90% ye-silicon.Intsalela yintsimbi, malunga ne-2% ebandakanya ezinye izinto ezifana ne-aluminiyam kunye ne-calcium.Ubuninzi be-silica busetyenziselwa ukuthintela ukubunjwa kwe-silicon carbide.I-Microsilica yimveliso eluncedo.

I-mineral perryite ifana nei-ferrosilicon, kunye nokwakheka kwayo Fe5Si2.Xa idibana namanzi, i-ferrosilicon inokuvelisa kancinci i-hydrogen.Ukusabela, okukhawulezileyo phambi kwesiseko, kusetyenziselwa ukuveliswa kwe-hydrogen.Indawo yokunyibilika kunye noxinano lweferrosilicon kuxhomekeke kumxholo wesilicon, kunye neendawo ezimbini eziphantse zibe yi-eutectic, enye kufuphi ne-Fe2Si kunye neyesibini idibanisa uluhlu lwe-FeSi2-FeSi3.

Usebenzisa

Ferrosiliconisetyenziswa njengomthombo we-silicon ukunciphisa isinyithi kwii-oxides zazo kunye ne-deoxidize intsimbi kunye nezinye i-alloys ene-ferrous.Oku kuthintela ukulahleka kwekhabhoni kwintsimbi etyhidiweyo (ebizwa ngokuba kukuthintela ubushushu);i-ferromanganese, i-spiegeleisen, i-calcium silicides, kunye nezinye izinto ezininzi zisetyenziselwa injongo enye.Ingasetyenziselwa ukwenza ezinye ii-ferroalloys.I-Ferrosilicon ikwasetyenziselwa ukwenziwa kwesilicon, ukumelana nokutyiwa kunye nobushushu obuphezulu obuxhathisa i-silicon alloys, kunye nentsimbi yesilicon yee-electromotors kunye ne-transformer cores.Ukwenziwa kwesinyithi esityhidiweyo, i-ferrosilicon isetyenziselwa ukugonywa kwentsimbi ukukhawulezisa i-graphitization.Kwi-arc welding, i-ferrosilicon inokufumaneka kwezinye iingubo ze-electrode.

I-Ferrosilicon sisiseko sokwenziwa kwe-prealloys efana ne-magnesium ferrosilicon (MgFeSi), esetyenziselwa ukuveliswa kwentsimbi ye-ductile.I-MgFeSi iqulethe i-3-42% ye-magnesium kunye nexabiso elincinci leentsimbi ezinqabileyo zomhlaba.I-Ferrosilicon nayo ibalulekile njenge-additive to cast irons ukulawula umxholo wokuqala we-silicon.

I-Magnesium ferrosilicon iluncedo ekwenzeni amaqhuqhuva, anika i-iron eguquguqukayo.Ngokungafaniyo nentsimbi engwevu, eyenza iiflakthi zegraphite, i-iron ductile inamaqhuqhuva egraphite, okanye imingxuma, eyenza kube nzima ngakumbi ukuqhekeka.
