Raws li cov khoom siv tseem ceeb rau kev tsim steel niaj hnub no, ferroalloy siv nyiaj rau 2%-4% (20-40} kg) ntawm ib tuj ntawm steel ntau lawm. Nrog rau kev txhim kho tas mus li thiab nrawm ntawm kuv lub teb chaws txoj kev lag luam steel, ntau yam ntawm cov hlau txuas ntxiv nthuav dav thiab ua kom zoo dua qub. Kuj tseem muaj cov kev xav tau siab dua rau cov khoom siv ferroalloy, thiab lawv cov kev siv kuj txawv, xws li deoxidizers, alloying agents, casting nucleation inoculants, txo cov neeg ua hauj lwm, thiab lwm yam.
Nyob rau tib lub sijhawm, muaj ntau pua ntawm ferroalloy ntau yam raws li cov kev cai sib txawv rau steelmaking.
Ntawm lawv, peb loj series ntawmsilicon, manganesethiabchromiumaccount rau ntau tshaj 90% ntawm tag nrho cov zis ntawm ferroalloys, yog li silicon, manganese thiab chromium hu ua "peb seasoning kwv tij". Txij li thaum "Peb Cov Kwv Tij" yog qhov nyuaj thiab raug nqi los ua kom huv thiab siv rau hauv daim ntawv ntawm cov hlau sib txuas, lawv cov teebmeem yuav luag zoo ib yam li cov khoom ntshiab. Yog li ntawd, "Peb Cov Kwv Tij" yog feem ntau nyob rau hauv daim ntawv ntawm alloys xws li ferrosilicon, manganese-silicon, thiab ferrochromium. nyob thiab siv.
Lawv lub luag haujlwm hauv steelmaking yog raws li hauv qab no:
Manganese:Nce lub zog thiab hardness ntawm steel.
Silicon: Txhim kho lub elasticity thiab tensile lub zog ntawm steel, thiab txhim khu lub magnetic permeability ntawm hlau.
Chromium:ua rau cov hlau muaj kev tiv thaiv zoo corrosion thiab hnav tsis kam, thiab yog cov khoom siv tseem ceeb rau kev tsim cov hlau tsis muaj steel.
