Ferro Silicon hmoov yog ib hom ferroalloy uas yog tsim los ntawm lub rooj sab laj thiab silicon. Cov ferrosilicon yog nyiaj grey thiab feem ntau yog siv los ua cov inoculants thiab nodulizers hauv kev lag luam casting thiab deoxidizer hauv steelmaking. Nws yog tsuas yog siv hauv kev tsim cov hlau thiab cam khwb cia hlau thiab tsim cov hlau zoo. Ferro Silicon yog siv los tshem tawm cov pa tawm ntawm cov hlau kom zoo dua qub thiab ua haujlwm ntev. Peb cov neeg siv khoom kuj tseem siv Ferro Silicon los tsim cov khoom ua ntej xws li Magnesium Ferro Silicon (FeSiMg). Nws yog siv los hloov cov hlau melted malleable hlau.
Daim ntawv thov:
1. siv los ua deoxidizer thiab tsis kam ua cov hlau ua.
2. siv los ua inoculant thiab nodulizer hauv kev lag luam casting.
3.siv raws li alloy caij additives.
