Kupanga ndi zochita

Ferrosiliconamapangidwa ndi kuchepetsa silika kapena mchenga ndi coke pamaso pa chitsulo.Magwero achitsulo ndi chitsulo chachitsulo kapena mphero.Ma Ferrosilicon okhala ndi silicon okwana pafupifupi 15% amapangidwa m'ng'anjo zophulika zomangika ndi njerwa zamoto za asidi.Ma Ferrosilicon okhala ndi silicon yapamwamba amapangidwa m'ng'anjo zamagetsi zamagetsi.Zomwe zimapangidwira pamsika ndi ma ferrosilicon okhala ndi 15%, 45%, 75%, ndi 90% silicon.Chotsaliracho ndi chitsulo, ndipo pafupifupi 2% imakhala ndi zinthu zina monga aluminium ndi calcium.Kuchuluka kwa silika kumagwiritsidwa ntchito poletsa mapangidwe a silicon carbide.Microsilica ndi chinthu chothandiza.

A mineral perryite ndi ofanana ndiferrosilicon, ndi kapangidwe kake Fe5Si2.Pokhudzana ndi madzi, ferrosilicon imatha kutulutsa haidrojeni pang'onopang'ono.Zomwe zimachitika, zomwe zimachulukitsidwa pamaso pa maziko, zimagwiritsidwa ntchito popanga haidrojeni.Malo osungunuka ndi kachulukidwe ka ferrosilicon zimadalira zomwe zili ndi silicon, zomwe zili ndi madera awiri omwe ali pafupi ndi eutectic, imodzi pafupi ndi Fe2Si ndi yachiwiri yozungulira FeSi2-FeSi3.

Ntchito

Ferrosiliconamagwiritsidwa ntchito ngati gwero la silicon kuchepetsa zitsulo kuchokera ku ma oxides awo komanso kutulutsa zitsulo ndi ma aloyi ena achitsulo.Izi zimalepheretsa kutaya kwa carbon ku chitsulo chosungunuka (chotchedwa kutsekereza kutentha);ferromanganese, spiegeleisen, calcium silicides, ndi zinthu zina zambiri amagwiritsidwa ntchito pa cholinga chomwecho.Atha kugwiritsidwa ntchito popanga ma ferroalloys ena.Ferrosilicon imagwiritsidwanso ntchito popanga silicon, zolimbana ndi dzimbiri komanso zosagwira kutentha kwambiri za silicon alloys, ndi chitsulo cha silicon pama electromotor ndi ma thiransifoma cores.Popanga chitsulo chosungunula, ferrosilicon imagwiritsidwa ntchito popanga chitsulo kuti ifulumizitse graphitization.Powotcherera arc, ferrosilicon imapezeka mu zokutira zina za elekitirodi.

Ferrosilicon ndi maziko opangira ma prealloys ngati magnesium ferrosilicon (MgFeSi), omwe amagwiritsidwa ntchito popanga chitsulo cha ductile.MgFeSi ili ndi 3-42% ya magnesiamu ndi zitsulo zochepa zapadziko lapansi.Ferrosilicon ndiyofunikiranso ngati chowonjezera chopangira zitsulo zowongolera zomwe zili mu silicon.

Magnesium ferrosilicon imathandiza kupanga timinofu tomwe timapanga timafupa tating'ono, zomwe zimapangitsa kuti chitsulo cha ductile chisasunthike.Mosiyana ndi chitsulo chotuwira, chomwe chimapanga ma graphite flakes, chitsulo cha ductile chimakhala ndi tinthu tating'onoting'ono ta graphite, kapena ma pores, omwe amapangitsa kuti kung'ambika kukhala kovuta kwambiri.

Ferrosilicon imagwiritsidwanso ntchito mu njira ya Pidgeon kupanga magnesium kuchokera ku dolomite.Chithandizo cha high-silicon ferrosilicon ndi wa hydrogen kolorayidi ndi maziko a kaphatikizidwe mafakitale trichlorosilane.

Ferrosilicon imagwiritsidwanso ntchito mu chiŵerengero cha 3-3.5% popanga mapepala a maginito ozungulira magetsi.
