Ferrosilicon Fesi

Ferrosilicon (FeSi) yog ib qho alloy ntawm hlau thiab silicon uas yog feem ntau siv hauv steelmaking rau deoxidation thiab ua ib qho alloying tivthaiv. Elkem yog ib qho ntawm cov khoom lag luam loj tshaj plaws ntawm cov nqi hwm - qib ferrosilicon ferroalloys thoob ntiaj teb, thiab peb npaj txhij los pab koj txheeb xyuas cov khoom zoo tshaj plaws rau koj daim ntawv thov.

Ferrosilicon, feem ntau abbreviated FeSi, yog ib qho hlau-silicon alloy uas tseem muaj cov feem me me ntawm lwm cov ntsiab lus. Cov qib nrov tshaj plaws ntawm ferrosilicon muaj 75 wt% silicon ('FeSi75'), tab sis tus nqi tuaj yeem nyob ntawm 15-90 wt% nyob ntawm daim ntawv thov.

Qhov siab tshaj - zoo ferrosilicon yog tsim nyob rau hauv ib tug hluav taws xob arc rauv los ntawm kev txo silica nrog coke nyob rau hauv lub xub ntiag ntawm hlau (feem ntau muab tau los ntawm steel seem los yog hlau ore). Cov ferrosilicon feem ntau yog siv rau hauv daim ntawv ci, nws yog xim hlau- grey lumps, tab sis kuj muaj raws li pre- tsim briquettes.

Hauv steelmaking, ferrosilicon yog siv rau:

Khoom ua haujlwm- Ferrosilicon yog ib txoj hauv kev yooj yim ntawm kev ntxiv silicon ua cov khoom sib xyaw, txhawm rau txhim kho ntau yam khoom ntawm cov hlau kawg.

Slag txo- Hauv kev tsim cov hlau tsis muaj steel, muaj cov silicon txo cov chromium oxides hauv cov yaj, txhim kho kev rov zoo ntawm cov hlau chromium.

Deoxidation- Ferrosilicon muab sai sai - ua kom tshem tawm cov pa tawm ntawm cov yaj, yog li zam kom tsis txhob muaj kev suav nrog - tsim oxides thiab tsis txhob poob ntawm cov khoom tsim nyog.

Roj- Qee lub mills hlau ntxiv ferrosilicon rau yaj kom nws tuaj yeem raug hlawv kom tau cua sov rau hauv qhov cub, thiab txo cov nqi hluav taws xob.

Ferrosilicon feem ntau categorized raws li cov theem ntawm ntau yam me me, nyob ntawm seb daim ntawv thov. Cov pawg no suav nrog:

Tsawg-carbon ferrosiliconthiabultra- qis- carbon ferrosilicon- Siv kom tsis txhob rov- qhia carbon thaum lub sij hawm tsim cov hlau tsis muaj steel thiab hluav taws xob hlau.

Tsawg-titanium (siab-purity) ferrosilicon- Siv kom tsis txhob muaj TiN thiab TiC suav nrog hauv cov hlau hluav taws xob thiab qee cov hlau tshwj xeeb.

Tsawg-aluminium ferrosilicon- Siv kom tsis txhob tsim cov tawv Al₂O₃thiab Al₂O₃-CaO suav nrog hauv ntau hom hlau.

Tshwj xeeb ferrosilicon- Ib lub ntsiab lus dav dav uas suav nrog ntau yam ntawm tus kws txiav- ua cov khoom lag luam uas muaj lwm cov ntsiab lus alloying.
