Pali njira ziwiri zazikulu zopangira ma ferroalloys, imodzi ndikugwiritsa ntchito mpweya wosakanikirana ndi njira zoyenera zosungunulira, ndipo ina ndiyo kuchepetsa metallothermic ndi zitsulo zina. Njira yakale nthawi zambiri imagwirizanitsidwa ndi ntchito zamagulu, pomwe yomalizayo imagwiritsidwa ntchito makamaka poyang'ana ma alloys apamwamba kwambiri omwe nthawi zambiri amakhala ndi mpweya wochepa.

Kuponyera zitsulo ndi njira yakale yomwe yakhala yofunika kwambiri pa chitukuko cha anthu kwa zaka zambiri. Kuchokera pakupanga ziboliboli zotsogola mpaka kupanga ma complex indus

Ferrosilicon ndi gawo lofunika kwambiri la ferroalloy lomwe limagwiritsidwa ntchito kwambiri muzitsulo zazitsulo ndi mafakitale opangira maziko. Nkhaniyi ifotokoza momveka bwino momwe ferrosilicon imapangidwira, kuphatikiza kusankha kwazinthu zopangira, njira zopangira, kuyenda kwadongosolo, kuwongolera bwino komanso kukhudza chilengedwe.

Aloyi ndi chosakaniza kapena cholimba chopangidwa ndi zitsulo. Momwemonso, ferroalloy ndi chisakanizo cha aluminiyamu chosakanikirana ndi zinthu zina monga manganese, alum.

Silicon metal ufa ndi gawo lofunikira kwambiri pamakampani opanga zitsulo. Amagwiritsidwa ntchito kwambiri ngati alloying alloying popanga mitundu yosiyanasiyana yazitsulo. Ndi mawonekedwe ake apadera komanso maubwino ake, ufa wachitsulo wa silicon umagwira ntchito yofunika kwambiri pakupititsa patsogolo ntchito zazitsulo. Nkhaniyi ikufuna kupereka kufufuza mozama kwa silicon chitsulo ufa wopangira zitsulo, kuwonetsa makhalidwe ake, ntchito, ndi ubwino womwe umapereka ku mafakitale azitsulo.

Silicon metal ufa ndi chinthu chofunika kwambiri cha mafakitale, chomwe chimagwiritsidwa ntchito kwambiri mu semiconductors, mphamvu ya dzuwa, ma alloys, labala ndi zina. M'zaka zaposachedwa, ndikukula mwachangu kwa mafakitale akumunsi, msika wapadziko lonse lapansi wa silicon metal powder wawonetsa chizolowezi chokhazikika.
