Ferrosilicon yog hlau silicon alloy ua los ntawm smelting coke, steel shavings, quartz (los yog silica) raws li raw cov ntaub ntawv nyob rau hauv lub cub hluav taws xob.
Kev siv ferrosilicon:
(1) Ferrosilicon yog deoxidizer hauv kev lag luam steel. Hauv steelmaking, ferrosilicon yog siv rau nag lossis daus deoxygenation thiab diffusion deoxygenation. Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking.
(2) Siv los ua inoculant thiab spheroidizer hauv kev lag luam cam khwb cia hlau. Hauv kev tsim cov hlau ductile, silicon hlau yog ib qho tseem ceeb inoculant (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev.
(3) Siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen siab, tab sis cov pa roj carbon ntsiab lus ntawm siab silicon ferrosilicon kuj tsawg heev. Yog li ntawd, siab silicon ferrosilicon (los yog siliceous alloys) yog ib tug nquag siv los txo tus neeg sawv cev nyob rau hauv zus tau tej cov low-carbon ferroalloys nyob rau hauv lub ferroalloy kev lag luam.
(4) 75 # ferrosilicon feem ntau yog siv rau hauv cov txheej txheem kub kub smelting ntawm hlau magnesium hauv cov txheej txheem Pijiang. Rau txhua tuj ntawm cov hlau magnesium tsim, kwv yees li 1.2 tons ntawm ferrosilicon tau noj, uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau magnesium.
(5) Rau lwm lub hom phiaj. Silicon hlau hmoov, uas tau raug nplua hauv av los yog atomized, yuav siv tau raws li ib tug ncua sij hawm nyob rau hauv cov ntxhia ua kev lag luam.
(6) Nws tuaj yeem siv los ua txheej txheej rau vuam rods hauv kev lag luam vuam pas nrig. High silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam tshuaj los tsim cov khoom xws li silicone.
Metallic silicon, tseem hu ua crystalline silicon los yog muaj silicon, feem ntau yog siv los ua ib qho ntxiv rau cov hlau tsis muaj hlau. Hlau silicon yog ib yam khoom uas tsim los ntawm smelting quartz thiab coke nyob rau hauv lub cub hluav taws xob, nrog ib tug tseem ceeb Cheebtsam ntawm silicon cov ntsiab lus ntawm txog 98%, thiab lwm yam impurities xws li hlau, txhuas, thiab calcium.
Kev faib tawm ntawm cov hlau silicon feem ntau yog ua raws cov ntsiab lus ntawm peb lub ntsiab impurities, hlau, txhuas, thiab calcium, muaj nyob rau hauv cov khoom ntawm hlau silicon. Raws li cov ntsiab lus ntawm hlau, txhuas, thiab calcium hauv hlau silicon, nws tuaj yeem muab faib ua ntau qib xws li 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, thiab lwm yam.
