Muaj ntau ntau hom ferroalloys. Raws li tus qauv, cia peb kawm txog nws:
(1) Ib leeg ferroalloy. Ib qho hlau uas muaj ib qho alloying tsuas yog hu ua ib qho ferroalloy. Nws lub ntsiab ntau yam yog ferrosilicon, ferromanganese, ferrochromium, ferromolybdenum, ferrotitanium, ferrotungsten, muaj silicon, ferroboron, ferrovanadium, metallic manganese, thiab lwm yam;
(2) Composite ferroalloy. Alloys uas muaj ob los yog ntau tshaj alloying ntsiab yog hu ua composite ferroalloys. Nws lub ntsiab ntau yam yog silicon manganese alloy, silicon calcium alloy, thiab lwm yam;
(3) Nitrided khoom. Nitrided khoom tsim los ntawm nitriding nrog ferromanganese los yog ferrochromium hmoov nyob rau hauv kub kub. Nws lub ntsiab ntau yam yog ferromanganese nitride, ferrochromium nitride, thiab lwm yam;
(4) Oxide agglomerates. Oxide agglomerates yooj yim txo los ntawm cov hlau kuj tuaj yeem ncaj qha ntxiv rau cov kua hlau ua cov khoom siv hlau, xws li molybdenum oxide agglomerates. Raws li cov kev cai ntawm steelmaking, lub teb chaws kuj faib ntau yam khoom rau hauv ob peb hom. Muaj ntau pua tus qauv ferroalloy (cov qauv hauv tebchaws) muab los ntawm lub xeev hauv Suav teb. Ntawm cov ferroalloy ntau yam, zus tau tej cov ferroalloy nyob rau hauv peb lub cev ntawm silicon, manganese thiab chromium yog loj heev, accounting rau ntau tshaj 90 feem pua ntawm tag nrho cov zis ntawm ferroalloy.
