Cov nyhuv ntawm kev ntxiv ferrosilicon nitride rau qhov zoo ntawm cov hlau

Ferrosilicon nitrideyog ib qho additive nyob rau hauv steel smelting thiab feem ntau yog siv nyob rau hauv lub casting ntawm ib co tshwj xeeb steels. Ferrosilicon nitride muaj qhov kub thiab txias tsis kam thiab tseem yog cov khoom siv raw ntau heev hauv kev teeb tsa ntawm cov phom phom av nplaum. Qhov sib ntxiv ntawm ferrosilicon nitride tsis tsuas yog ntxiv cov nitrogen uas yuav tsum tau rau cov hlau molten, tab sis cov silicon hauv nws kuj tuaj yeem cuam tshuam nrog cov pa hauv cov hlau molten kom tshem tawm cov pa ntau dhau. Qhov sib ntxiv ntawm silicon tuaj yeem ua rau muaj txiaj ntsig zoo rau cov hlau. Qee qhov kev txhim kho. Cia peb saib qhov cuam tshuam ntawm qhov sib ntxiv ntawm ferrosilicon nitride ntawm steel zoo.

silicon:
Silicon tuaj yeem yaj hauv ferrite thiab austenite los txhim kho qhov nyuaj thiab lub zog ntawm cov hlau. Nws cov nyhuv yog qhov thib ob rau phosphorus thiab muaj zog dua cov ntsiab lus xws li manganese, nickel, chromium, tungsten, molybdenum, thiab vanadium.

Silicon tuaj yeem txo qhov ntom ntom, thermal conductivity, thiab hluav taws xob conductivity ntawm hlau. Nws tuaj yeem txhawb cov coarsening ntawm ferrite nplej thiab txo cov quab yuam. Nws nyhav kom txo cov anisotropy ntawm cov siv lead ua, ua kom magnetization yooj yim dua thiab txo cov hlau nplaum tiv thaiv. Nws tuaj yeem siv los tsim hluav taws xob hlau, yog li qhov sib nqus hysteresis poob ntawm silicon steel los xij yog tsawg. Silicon tuaj yeem nce qhov sib nqus permeability ntawm ferrite, ua rau cov ntawv hlau muaj zog sib nqus induction ntau dua nyob rau hauv qhov tsis muaj zog hlau nplaum. Txawm li cas los xij, silicon txo qhov sib nqus induction ntawm cov hlau nyob rau hauv cov hlau nplaum muaj zog. Silicon muaj zog deoxidizing zog, yog li txo qhov kev laus ntawm cov hlau nplaum.

nitrogen:
Lub corrosion kuj ntawm steel tsis pom tseeb, tab sis nitriding nto ntawm cov hlau tsis tsuas yog tsub kom nws hardness thiab hnav tsis kam, tab sis kuj txhim kho nws corrosion kuj.

Txij li thaum nitride precipitates ntawm cov ciam teb nplej, nws tuaj yeem txhim kho qhov kub-kub lub zog ntawm cov qoob loo ciam teb thiab ua kom lub zog nkag ntawm cov hlau.

Residual nitrogen hauv cov hlau me me tuaj yeem ua rau muaj hnub nyoog brittleness. High-nitrogen steel muaj qhov zoo tshwj xeeb ntawm cov khoom siv dav xws li lub zog, tawg toughness, hnav tsis kam, hlau nplaum, thiab corrosion kuj.

Hauv cov ntsiab lus, peb tau qhia rau koj txog qhov cuam tshuam ntawm qhov sib ntxiv ntawm ferrosilicon nitride ntawm steel zoo. Tsuas yog los ntawm kev nkag siab cov no tuaj yeem ua tau zoo dua nws cov txiaj ntsig hauv kev siv tswv yim yav tom ntej. Cov ntsiab lus ntawm ntau yam khoom siv hauv cov khoom siv ntxiv hauv cov txheej txheem steel smelting yuav tsum tau tswj nruj me ntsis. Ntau dhau los yog tsawg dhau ntawm cov ntsiab lus ntxiv yuav cuam tshuam rau qhov zoo ntawm cov hlau. Rau cov kev paub dhau los thiab thev naus laus zis ntawm cov neeg ua haujlwm tsim kho, Lawv tag nrho cov kev xeem nruj.

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.
