Cov tshuaj sib xyaw ua ke ntawm silicon thiab oxygen yog zoo li ntawd ferrosilicon yog siv los ua deoxidizer (nag lossis daus deoxidization thiab diffusion deoxidization) hauv kev lag luam steelmaking. Dhau ntawm cov hlau rimmed thiab semi-tua steel, cov ntsiab lus silicon hauv steel yuav tsum tsis pub tsawg dua 0.10%. Silicon tsis tsim cov carbides hauv steel, tab sis tshwm sim ua cov khoom tov rau hauv ferrite thiab austenite. Silicon ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog ntawm cov tshuaj muaj zog thiab tus nqi ntawm kev ua haujlwm txias deformation thiab ua kom tawv tawv, tab sis nws txo qhov nro thiab plasticity ntawm hlau. Qhov cuam tshuam rau steel hardenability yog nruab nrab, tab sis tuaj yeem txhim kho steel tempering stability thiab oxidation tsis kam, yog li ferrosilicon yog siv los ua tus neeg sawv cev hauv cov hlau ua haujlwm kev lag luam. Silicon kuj muaj cov txheej txheem ua haujlwm siab dua, muaj cov thermal conductivity thiab lub zog sib nqus tau zoo heev. Muaj qee qhov nqi ntawm silicon hauv steel, tuaj yeem txhim kho qhov permeability ntawm steel, txo hysteresis poob thiab eddy tam sim no poob. Hluav taws xob cov hlau muaj 2% ~ 3% Si, tab sis yuav tsum muaj titanium thiab boron cov ntsiab lus tsawg. Kev txuas ntxiv ntawm silicon hauv cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbide thiab txhawb nqa cov nag lossis daus thiab spheroidization ntawm graphite. Silicon magnesium hlau yog ib tus neeg sawv cev spheroidizing ntau. Ferrosilicon muaj barium, zirconium, strontium, bismuth, manganese, tsis tshua muaj lub ntiaj teb, thiab lwm yam., Siv los ua tus neeg sawv cev inbreeding hauv cam khwb cia hlau ntau lawm. Lub siab silicon hlau yog qhov ua kom txo qis rau kev tsim cov pa roj carbon monoxide qis hauv ferroalloy kev lag luam.
