kev siv ferro silicon
1. Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Nyob rau hauv lub teeb steel, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation.
2. High-silicon ferrosilicon lossis siliceous alloy yog siv los ua tus neeg sawv cev txo qis rau kev tsim cov pa roj carbon monoxide qis hauv kev lag luam ferroalloy. Ferrosilicon tuaj yeem siv los ua ib qho inoculant rau cov hlau nplaum, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus ntawm graphite, thiab txhim kho cov khoom ntawm cam khwb cia hlau.
3. Ferrosilicon hmoov tuaj yeem siv tau raws li lub sijhawm ncua kev lag luam hauv kev lag luam ntxhia thiab ua txheej txheej rau vuam rods hauv kev lag luam electrode.
4. Ferrosilicon feem ntau yog siv nyob rau hauv high-kub smelting txheej txheem ntawm magnesium hlau nyob rau hauv Pijiang txoj kev ntawm magnesium smelting, hloov cov magnesium nyob rau hauv CaO.MgO, thiab noj txog 1.2 tons ntawm ferrosilicon rau txhua tuj ntawm magnesium hlau tsim, uas plays a lub luag haujlwm tseem ceeb hauv kev tsim cov hlau magnesium.
5. Lwm yam kev siv. Finely hauv av los yog atomized ferrosilicon hmoov yuav siv tau raws li ib tug ncua sij hawm nyob rau hauv cov ntxhia ua kev lag luam. Nws tuaj yeem siv los ua txheej txheej rau vuam rods hauv kev lag luam electrode. High-silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam tshuaj los ua cov khoom xws li silicone.
Cov yam ntxwv ntawm ferro silicon
Kev lag luam: Hauv qee qhov kev thov, kev siv ferrosilicon tuaj yeem txo cov nqi.
Microstructure: Ferrosilicon tuaj yeem txo lub qhov ncauj dawb, txhim kho qhov sib luag ntawm cov qauv ntoo khaub lig, txhawb kev tsim ntawm A-hom graphite, nce cov eutectic pawg, thiab txo kev sib cais.
Kev txhim kho kev ua haujlwm: Kev siv ferrosilicon tuaj yeem txhim kho lub zog thiab toughness ntawm cov khoom.
Kev sib raug zoo ntawm qhov ntom ntom thiab cov ntsiab lus silicon: Qhov ceev ntawm ferrosilicon nce nrog kev nce ntawm silicon cov ntsiab lus. Cov cuab yeej no tuaj yeem siv los txiav txim siab sai npaum li cas ntawm silicon hauv ferrosilicon.
Kev cais: Vim muaj qhov sib txawv loj ntawm qhov ceev ntawm txhua theem hauv ferrosilicon, ferrosilicon alloys yog qhov yooj yim rau kev sib cais, uas ua rau qhov sib txawv ntawm cov ntsiab lus silicon ntawm sab sauv thiab qis ntawm cov hlau ingot yuav ntau dua 20%. Qhov ntau dua qhov tuab ntawm cov hlau ingot, ntev lub sij hawm solidification, thiab qhov loj dua qhov sib cais tshwm sim.
Chalking nyiam: ferrosilicon nrog silicon cov ntsiab lus ntau dua 33.46% muaj chalking nyiam, tshwj xeeb tshaj yog ferrosilicon nrog 50% ~ 60% silica muaj ntau dua pulverization nyiam.
Tshuaj stability: Ferrosilicon yog cov khoom lag luam ruaj khov.
Deoxidation thiab alloying: Hauv kev lag luam steelmaking, ferrosilicon yog siv los ua deoxidizer thiab alloying tus neeg sawv cev. Nws muaj cov tshuaj lom neeg muaj txiaj ntsig zoo nrog oxygen thiab yog lub zog oxygen absorber, uas tuaj yeem siv rau nag lossis daus thiab diffusion deoxygenation. Tsis tas li ntawd, ferrosilicon txhim kho cov morphology ntawm inclusions thiab txo cov roj cov ntsiab lus hauv cov hlau molten, yog li txhim kho cov hlau zoo, txo cov nqi thiab txuag hlau.
