Ferrosilicon feem ntau yog siv nyob rau hauv steelmaking vim nws yooj yim sib xyaw nrog oxygen los ua silicon dioxide. Silicon Dioxide (Sio2) ua ntau cov cua sov thaum nws muaj txiaj ntsig zoo rau kev nce siab rau kev kub ntxhov thaum deoxidation. Ferrosilicon kuj tseem siv tau los tsim lwm cov hlau thiab feem ntau siv hauv cov hlau tsis muaj roj, cov kabmob hlau, kub resistant hlau thiab hlau silicon hlau.
Ferrosilicon feem ntau siv los ua tus neeg sawv cev txo qis hauv kev tsim cov ferroalloys thiab hauv kev lag luam tshuaj lom neeg. Ferrosilicon yog siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steel. Kev siv tshuaj lom neeg nruab nrab ntawm silicon thiab oxygen yog muaj zog heev, yog li ferrosilicon yog lub zog deoxidizing hauv steelmaking thiab yog siv rau ntau hom kev deoxidation. Ntxiv ib qho nyiaj ntawm silicon rau cov hlau tuaj yeem ua rau nws muaj zog, hardingity thiab elasticity. Qhov no yog vim li cas nws yog siv nyob rau hauv kev tsim cov txheej txheem hlau (uas muaj cov hlau (ferrosilicon) thiab lub caij nplooj ntoo hlau (uas muaj 2.81-4.8% sillicon). Nws kuj tseem tuaj yeem txhim kho qhov zoo ntawm cov hlau, txo tus nqi thiab txuag hlau. Nws yog qhov tshwj xeeb tshaj yog qhov tshwj xeeb tshaj yog thaum tshem tawm cov oxides los ntawm cov hlau molten. Tsis tsuas yog muaj ferrosilicon tau pom tias tau tshem tawm cov oxides hauv steelmaking, tab sis nws tseem muaj cov txiaj ntsig ntawm kev ua hnyav thiab muaj zog.
