High carbonferrochromendi imodzi mwa ferroalloys wamba opangidwa ndipo pafupifupi ntchito kupanga zitsulo zosapanga dzimbiri ndi mkulu chromium zitsulo.Kupanga kumachitika makamaka m'maiko omwe ali ndi miyala yamtengo wapatali ya chromite.Magetsi otsika mtengo komanso ochepetsera amathandizanso kuti mpweya wa ferrochrome ukhale wolimba.Ukadaulo wodziwika bwino womwe umagwiritsidwa ntchito ndi kusungunula kwa arc pansi pamadzi mu ng'anjo za AC, ngakhale kusungunula kwa arc mu ng'anjo za DC kukuchulukirachulukira.Njira yaukadaulo yotsogola kwambiri yomwe ili ndi gawo lochepetseratu imangogwiritsidwa ntchito ndi wopanga m'modzi.Njira zopangira zakhala zopatsa mphamvu komanso zopangira zitsulo pogwiritsa ntchito njira zapamwamba monga kuchepetsa, kutentha, kuphatikizika kwa ore, ndi kugwiritsa ntchito mpweya wa CO.Zomera zomwe zakhazikitsidwa posachedwapa zimawonetsa zoopsa zomwe zingatheke powononga chilengedwe komanso thanzi lantchito.

Zoposa 80% za ferrochrome zomwe zimatuluka padziko lapansi zimagwiritsidwa ntchito popanga zitsulo zosapanga dzimbiri.Chitsulo chosapanga dzimbiri chimadalira chromium chifukwa cha mawonekedwe ake komanso kukana kwake ku dzimbiri.Pafupifupi chromium muzitsulo zosapanga dzimbiri ndi 18%.FeCr imagwiritsidwanso ntchito pamene ikufunika kuwonjezera chromium ku carbon steel.FeCr yochokera ku South Africa yotchedwa "charge chrome" ndipo yopangidwa kuchokera ku ore ya chrome yamtengo wapatali imagwiritsidwa ntchito kwambiri popanga zitsulo zosapanga dzimbiri.Mpweya wa carbon FeCr wopangidwa kuchokera ku miyala yamtengo wapatali yomwe imapezeka ku Kazakhstan (pakati pa malo ena) imagwiritsidwa ntchito kwambiri pa ntchito zapadera monga zitsulo zaumisiri pomwe chiŵerengero chapamwamba cha Cr mpaka Fe n'chofunikira.

Kupanga ferrochrome kwenikweni ndi ntchito yochepetsera kutentha kwambiri kwa carbothermic.Chrome ore (osayidi wa chromium ndi chitsulo) amachepetsedwa ndi coke (ndi malasha) kuti apange iron-chromium-carbon alloy.Kutentha kwa njirayi kumaperekedwa makamaka kuchokera ku arc yamagetsi yomwe imapangidwa pakati pa nsonga za maelekitirodi pansi pa ng'anjo ndi ng'anjo ya ng'anjo mu ng'anjo zazikulu kwambiri zotchedwa "ng'anjo zamadzi."Monga dzina limatanthawuzira kuti ma elekitirodi atatu a carbon a ng'anjo amamizidwa mu bedi lomwe limakhala lolimba komanso lamadzimadzi osakaniza opangidwa ndi kaboni wolimba (coke ndi / kapena malasha), zolimba za oxide zopangira (ore ndi fluxes) komanso madzi a FeCr aloyi ndi madontho osungunuka a slag omwe akupangidwa.Pakusungunula, magetsi ambiri amadyedwa.Kugogoda kwa zinthu kuchokera ku ng'anjo kumachitika pang'onopang'ono.Pamene ng'anjo yosungunuka yokwanira yachulukana, bowolo limabowoledwa ndipo zitsulo zosungunuka ndi slag zimatuluka pansi pa ng'anjoyo n'kukhala ozizira kapena ladle.Ferrochrome imakhazikika m'magulu akuluakulu, omwe amaphwanyidwa kuti agulitse kapena kukonzedwanso.
