Cov lus qhia luv luv:
Tsawg aluminium ferrosilicon yog ib hom ferrosilicon, cov ntsiab lus aluminium yog qhov qis dua li ntawm cov ferrosilicon dav, thiaj li hu ua cov txhuas qis thiab silicon, silicon hauv cov nyiaj, nrog cov xim hlau, vim hais tias silicon yog yooj yim los ua ke nrog oxygen los ua silicon dioxide, yog li lub sijhawm ntawm ferrosilicon feem ntau siv rau hauv steelmaking deoxidizer, vim tias SiO2 tsim nyob rau tib lub sij hawm muab ntau ntawm tshav kub, nyob rau tib lub sijhawm DNA, txhawm rau txhim kho kev qhia zoo ntawm molten steel kub kuj zoo.

SIV:
(1) Ferrosilicon yog qhov tseem ceeb deoxidizer hauv kev lag luam steelmaking. Hauv kev siv hlau ua, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. Lub cib hlau kuj tseem siv los ua tus neeg saib xyuas kev tiv thaiv hauv kev siv hlau ua yeeb yam.
(2) Siv raws li inoculant thiab spheroidizing tus neeg sawv cev hauv cam khwb cia hlau kev lag luam. Hauv kev tsim cov hlau ductile, 75 ferrosilicon yog qhov tseem ceeb inoculant (los pab precipitate graphite) thiab tus neeg sawv cev spheroidizing.
(3) Siv los ua tus neeg sawv cev txo qis hauv kev ua haujlwm ntawm ferroalloy. Tsis tsuas yog muaj cov tshuaj lom neeg nruab nrab ntawm silicon thiab oxygen yog qhov zoo, tab sis kuj muaj cov pa roj carbon ntsiab lus ntawm siab silicon ferrosilicon yog qhov tsawg heev. Yog li ntawd, siab silicon ferrosilicon (los yog siliceous alloy) yog ib qho kev txo qis cov neeg sawv cev siv hauv kev tsim cov roj carbon tsawg kawg hauv kev ua lag luam ferroalloy.
(4) 75 ferrosilicon feem ntau siv nyob rau hauv cov txheej txheem ntawm kev kub-siab smelting ntawm magnesium nyob rau hauv cov txheej txheem pijiang. Cov hlau nplaum hauv CaO. MgO yog hloov pauv, thiab li ntawm 1.2 tons ntawm ferrosilicon yog noj rau txhua qhov tuj ntawm cov khoom lag luam magnesium, uas yog lub luag haujlwm tseem ceeb hauv kev tsim cov dej magnesium.
(5) Rau lwm lub hom phiaj. Pulverized lossis atomized ferrosilicon hmoov yuav siv tau los ua ntu ncua ntawm cov ntxhia ua kev lag luam.
(6) Hauv kev lag luam hauv tshuab hluav taws xob electrode tuaj yeem siv cov txheej txheem electrode. Lub siab silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam chemical los tsim silicone thiab lwm yam khoom.
