Ferrosilicon yog ib hom ferroalloy uas yog tsim los ntawm kev txo cov silica los yog xuab zeb nrog coke nyob rau hauv muaj hlau.Tej qhov chaw ntawm hlau yog cov hlau los yog millscale.Ferrosilicons nrog silicon cov ntsiab lus txog li 15% yog tsim nyob rau hauv blast furnaces lined nrog acid hluav taws cib.Ferrosilicons nrog cov ntsiab lus ntau dua silicon yog tsim nyob rau hauv hluav taws xob arc rauv.Cov formulations ib txwm nyob rau hauv kev ua lag luam yog ferrosilicons nrog 60-75% silicon.Cov seem yog hlau, muaj li ntawm 2% muaj lwm yam xws li txhuas thiab calcium.Ib qho overabundance ntawm silica yog siv los tiv thaiv kev tsim ntawm silicon carbide.
Daim ntawv thov:
① Raws li deoxidizer thiab alloy tus neeg sawv cev hauv kev lag luam steelmaking
② Raws li inoculant thiab spheroidizing tus neeg sawv cev hauv cam khwb cia hlau
③As txo tus neeg sawv cev hauv ferroalloy ntau lawm
④Raws li tus neeg sawv cev hloov chaw hauv cov smelting ntawm magnesium
⑤ Hauv lwm qhov chaw ua haujlwm, milled lossis atomizing silicon hlau hmoov tuaj yeem siv tau raws li theem kev ncua.
