1. Ferrous hlau hais txog hlau thiab hlau alloys.Xws li steel, npua hlau, ferroalloy, cam khwb cia hlau, thiab lwm yam. Ob leeg steel thiab npua hlau yog alloys raws li hlau thiab nrog carbon raws li lub ntsiab ntxiv ntsiab, collectively hu ua hlau-carbon alloys.
Npua hlau yog hais txog cov khoom tsim los ntawm smelting hlau ore nyob rau hauv lub qhov cub tawg, uas yog tsuas yog siv rau steelmaking thiab casting.
Cov cam khwb cia hlau yog smelted nyob rau hauv ib tug hlau melting rauv, uas yog, cam khwb cia hlau (kua) yog tau, thiab cov kua cam khwb cia hlau yog cam khwb cia rau hauv ib tug casting, uas yog hu ua cam khwb cia hlau.
Ferroalloy yog ib qho alloy uas muaj hlau thiab silicon, manganese, chromium, titanium thiab lwm yam khoom.Ferroalloy yog ib qho ntawm cov khoom siv raw rau steelmaking.Nws yog siv los ua deoxidizer thiab alloying ntsiab additive rau steel thaum steelmaking.
2. Muab npua hlau rau steelmaking rau hauv steelmaking rauv thiab smelt nws raws li ib tug txheej txheem kom tau hlau.Cov khoom siv hlau muaj xws li ingots, nruam casting billets thiab ncaj qha mus rau hauv ntau yam hlau castings.Feem ntau hais lus, steel feem ntau yog hais txog cov hlau uas tau dov rau hauv ntau hom hlau.Hlau yog cov hlau ferrous tab sis steel tsis raws nraim sib npaug rau ferrous hlau.
3. Non-ferrous hlau, tseem hu ua non-ferrous hlau, xa mus rau cov hlau thiab alloys uas tsis yog ferrous hlau, xws li tooj liab, tin, lead, zinc, txhuas, thiab tooj dag, bronze, aluminium alloys thiab bearing alloys.Tsis tas li ntawd, chromium, npib tsib xee, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, thiab lwm yam kuj siv hauv kev lag luam.Cov hlau no feem ntau yog siv los ua cov hlau nplaum ntxiv los txhim kho cov khoom ntawm cov hlau.Ntawm lawv, tungsten, titanium, molybdenum, thiab lwm yam feem ntau yog siv los tsim riam.Carbide siv.
Cov hlau uas tsis yog-ferrous saum toj no yog tag nrho cov hu ua cov hlau, ntxiv rau cov hlau muaj txiaj ntsig: platinum, kub, nyiaj, thiab lwm yam thiab cov hlau tsis tshua muaj xws li hluav taws xob uranium, radium, thiab lwm yam.
