Ferrroalloys feem ntau yog siv raws li: Deagidizers: Tshem tawm cov pa los ntawm cov hlau molten los ntawm steelmaking steelmaking. Qee cov ferroalloys kuj tseem tuaj yeem tshem tawm lwm cov impurities nyob rau hauv cov hlau, xws li sulphur thiab nitrogen. Alloying Ntxiv: Cov ntsiab lus ntxiv rau cov hlau txhawm rau txhim kho cov yam ntxwv ntawm cov hlau raws li cov kev tsim ntawm qib tus qib. Inoculant: ntxiv rau molten hlau ua ntej caming los txhim kho cov qauv crystalline ntawm cov casting.
Qhov dav dav siv deoxidants hauv statmanpants yog manganese nrog silicon, ferromanganese thiab ferrosilicon. Muaj zog deoxidizers yog txhuas (txhuas- pcium), sicicon {{{}}} • zirconium, thiab lwm yam. Ferromanganese, Ferriachrome, ferrosilicon, ferrosilicon, ferromolsten, ferriapoly, ferroboron, thiab lwm yam. Ntau yam ferroalloys tseem muab faib ua ntau cov qib kawm nyob ntawm cov ntsiab lus ntawm alloy cov ntsiab lus lossis cov ntaub ntawv ntawm kev siv cov impurities yog txwv tsawg. Ferroalloys muaj ob lossis ntau lub ntsiab lus piav qhia yog hu ua composalalloys. Thaum siv hom ferrinoalloys, deoxidizing lossis alloying cov ntsiab lus ntxiv, tso cai rau kev siv nyiaj txiag dav dav thiab kev lag luam muaj cov peev txheej. Siv feem ntau: manganese silicon, sicalon zirmium, sici manganese aluminium, silicon {manganese calcium, tsawg dua lub ntiaj teb silicon hlau, thiab lwm yam.
Ntshiab hlau cov khoom sib ntxiv rau cov hlau nplaum muaj xws li txhuas, npib chromium, thiab lwm yam yooj yim rau cov moo thiab nio kuj siv los hloov cov ferroalloys. Tsis tas li ntawd, muaj nitred ferrroalloys, xws li nitrided ferriarollome thiab ferromanganese, raws li zoo li rhuab ferroalloys tov nrog cov neeg sawv cev cua sov.
