Ferroalloy yog ib qho tseem ceeb thiab tseem ceeb raw cov ntaub ntawv nyob rau hauv steel kev lag luam thiab mechanical casting kev lag luam.Nrog kev txhim kho tas mus li thiab nrawm ntawm Tuam Tshoj txoj kev lag luam steel, ntau yam thiab zoo ntawm cov hlau txuas ntxiv nthuav dav, ua kom muaj kev xav tau ntau dua rau cov khoom ferroalloy.
(1) Siv los ua Oxygen scavenger.Lub zog khi ntawm ntau yam hauv cov hlau molten rau oxygen, piv txwv li lub peev xwm deoxygenation, yog nyob rau hauv kev txiav txim ntawm lub zog los ntawm qaug zog mus rau lub zog: chromium, manganese, carbon, silicon, vanadium, titanium, boron, txhuas, zirconium, thiab calcium.Feem ntau siv deoxygenation hauv steelmaking yog hlau alloy muaj li ntawm silicon, manganese, txhuas, thiab calcium.
(2) Siv los ua tus neeg sawv cev alloying.Cov ntsiab lus los yog cov alloys siv los kho cov tshuaj muaj pes tsawg leeg ntawm steel rau alloying yog hu ua alloying agents.Feem ntau siv alloying ntsiab muaj xws li silicon, manganese, chromium, molybdenum, vanadium, titanium, tungsten, cobalt, boron, niobium, thiab lwm yam.
(3) Siv los ua tus neeg sawv cev nucleating rau casting.Txhawm rau hloov cov txheej txheem solidification, qee cov hlau alloys feem ntau yog ntxiv raws li siv lead ua nuclei ua ntej pouring, tsim cov chaw lis dej num, ua cov tsim graphite zoo thiab dispersed, thiab refining cov nplej, yog li txhim kho cov kev ua tau zoo ntawm cov casting.
(4) Siv los ua tus neeg sawv cev txo qis.Silicon hlau tuaj yeem siv los ua tus neeg sawv cev txo qis rau kev tsim cov ferroalloys xws li ferromolybdenum thiab ferrovanadium, thaum silicon chromium alloy thiab silicon manganese alloy tuaj yeem siv los txo cov neeg ua haujlwm rau kev ua kom zoo li nruab nrab mus rau qis carbon ferrochromium thiab nruab nrab rau qis carbon ferromanganese, raws li.
(5) Lwm lub hom phiaj.Hauv kev lag luam non-ferrous metallurgical thiab tshuaj lom neeg, ferroalloys kuj tau siv dav dav.
