Dab tsi yog lub ntsiab lus ntawmferrosilicon nitride hmoov?
Ferrosilicon nitride yog ib qho khoom siv hlau ua khoom siv. Hauv cov txheej txheem steel smelting, ferrosilicon nitride tuaj yeem tsis tsuas yog muab cov nitrogen rau cov hlau molten, tab sis kuj tshem tawm cov pa ntau dhau hauv cov hlau molten, thiab muaj cov nyhuv deoxidation zoo. Ntxiv rau kev siv los ua deoxidizer hauv steel smelting, ferrosilicon nitride kuj yog cov khoom siv raw rau silicon nitride ceramics. Nws muaj qhov zoo ntawm qhov kub thiab txias thiab hardness. Txhawm rau kom txhua tus nkag siab tob, cia peb txheeb xyuas qhov tshwm sim ntawm ferrosilicon nitride. Nws coj lub ntsiab lus li cas?
| Khoom | N | Si | Fe | O | Dej | granularity |
| FeSi3N 4 | 28-32% | 48-52% | 12-17% | 2.5% max | 0.3% max | 0-50mm Tshwj xeeb granularity tuaj yeem kho tau |
Ferrosilicon nitride yog dav siv nyob rau hauv ntau lub teb chaws tsim. Nws tuaj yeem txhim kho qhov qhib thiab thaiv kev ua tau zoo ntawm blast furnace av nkos thiab ua tau raws li qhov xav tau ntawm blast furnace tapping. Nws yog ib qho tseem ceeb ntawm cov niaj hnub loj blast furnace phom av nkos thiab ntxiv rau cov khoom siv hlau trench. Ib qho me me ntawm ferrosilicon nitride tuaj yeem ua kom cov hlau ntws tau zoo ntawm cov hlau trench high-ceev.
Nyob rau hauv steelmaking, granular ferrosilicon nitride yog siv nyob rau hauv zus tau tej cov oriented silicon steel. Nws muaj peev xwm ntxiv ib qho nyiaj ntawm nitrogen rau molten hlau nyob rau hauv ib qho kev ruaj khov. Tus nqi ntawm ferrosilicon nitride siv nyob rau hauv Tuam Tshoj mus txog ntau pua tons hauv ib xyoos. Kev nce qib ntawm smelting thev naus laus zis tau ua rau txoj kev loj hlob sai ntawm lub zog siab micro-alloyed steel ntau lawm hauv kuv lub tebchaws.
Lub ntsiab txhawb zog microalloying ntsiab ntawm hlau yog vanadium, niobium, m, thiab titanium. Tom qab suav, sib piv, n, thiab daim ntawv thov tsim tawm tiag tiag, FeV50+FeSi3N4 micro-alloying tov yog siv los tsim HRB400 steel tuav. Tus nqi alloying yog 127.61 yuan qis dua tus nqi ntawm FeV50-ton steel ib leeg, thiab 44.21 yuan qis dua tus nqi ntawm VN12 micro-alloyed steel. Yog tias cov cuab yeej no tau nrov, nws yuav yog qhov tseem ceeb rau cov tuam txhab tsim cov hlau tsim kom txo tau cov nqi thiab ua kom muaj txiaj ntsig zoo. Ferrosilicon nitride, raws li cov khoom pheej yig uas muab cov khoom siv nitrogen, muaj cov ntawv thov zoo hauv lwm hom hlau yav tom ntej.
Hauv cov ntsiab lus, qhov tseem ceeb ntawm ferrosilicon nitride tau sau tseg rau txhua tus. Nws yog siv nyob rau hauv ntau lub teb chaws tsim thiab yog ib tug zoo additive khoom. Txawm li cas los xij, kev smelting ntawm ferrosilicon nitride tsis yog qhov yooj yim, thiab tsis zoo ferrosilicon nitride kuj muaj kev cuam tshuam zoo rau kev smelting. Peb lub tuam txhab muab ntau hom ferrosilicon nitride nrog cov qauv ua tiav thiab cov lus qhia tshwj xeeb kom tau raws li koj xav tau. Yog tias koj xav paub ntau ntxiv, thov hu rau peb thiab peb yuav muab cov ntaub ntawv ntxiv rau koj.
Ferrosilicon nitride yog cov khoom siv ferroalloy feem ntau yog tsim los ntawm Si3N4, nrog rau cov hlau dawb, uas tsis yog-silicon nitride, thiab lwm yam khoom me me.
Kev lag luam ferrosilicon nitride rau refractory yog cov hmoov dawb los yog xim av, thaum cov hlau ua ferrosilicon nitride yog cov dawb dawb granular.
Granular ferrosilicon nitride feem ntau yog siv hauv silicon-oriented steel lossis lwm yam hlau (xws li HRB400 rebar) uas siv nitrides los txhim kho lub zog.
