① ferrosilicon nitride (FeSiN) yog dab tsi?
Ferrosilicon nitride (FeSiN, silicon nitride ferro alloy) - yog cov khoom siv hlau kub kub, uas yog cov hlau thiab silicon alloy nrog cov ntsiab lus tswj ntawm bound nitrogen nyob rau hauv daim ntawv ntawm silicon nitride (Si₃N₄) theem. Nyob rau hauv industrial xyaum nws yog xam raws lirefractory khoom additive, siv los txhim kho cov qauv ntawm refractories thiab ua rau kom lawv tsis kam mus rau huab cua kub.
Nyob rau hauv cov txheej txheem steelmaking, FeSiN tsim ib theem ruaj khov nitride uas ua raws li lub hauv paus kev txhawb zog nyob rau hauv lub refractory matrix. Vim li no, cov khoom siv tau dav siv nyob rau hauv cov cheeb tsam uas muaj thermal thiab tshuaj lom neeg kev nyuaj siab, nrog rau cov hauv ob sab phlu ntawm lub cub tawg thiab hlau troughs.
② Vim li cas ferrosilicon nitride tseem ceeb rau kev tsim steel?
Nyob rau hauv cov xwm txheej ntawm niaj hnub steelmaking, qhov tseem ceeb tshaj plaws yog qhov ruaj khov ntawm cov ntaub ntawv refractory ntawm qhov kub thiab txias thiab qhov cuam tshuam ntawm slag. Kev sivsib npaug nitrogen alloythiab hom ntaub ntawvTsawg impurity silicon nitride alloytso cai rau kom nce qhov kev pab cuam lub neej ntawm lub hauv ob sab phlu.
FeSiN tsis yog ib qho ntxiv - nws yog ib qho kev ua haujlwm uas hloov cov microstructure ntawm refractory. Thaum lub sijhawm ua haujlwm, nws txhawb kev tsim cov nitride bonds, txo cov porosity thiab ua rau muaj kev tiv thaiv slag corrosion.
Hauv cov tshuab hluav taws xob tawg thiab cov tshuab tsim hlau, qhov no yog qhov tseem ceeb tshwj xeeb, vim tias muaj kev cuam tshuam hauv ob sab phlu ua rau lub tsev kaw thiab kev ua haujlwm siab.

④ Qhov twg yog ferrosilicon nitride siv nyob rau hauv steelmaking txheej txheem?
Hauv kev lag luam steel, FeSiN feem ntau yog siv los ua cov khoom siv ntxiv rau cov khoom siv refractory, tshwj xeeb tshaj yog nyob rau hauv cov tshuab uas muaj thermal thiab tshuaj lom neeg.
Nyob rau hauv qhov cub tawg, nws yog siv nyob rau hauv hearth linings, chutes thiab tapholes, qhov twg hlau thiab slag nyob rau hauv tas li kev sib cuag nrog lub refractory nto. Ntawm no FeSiN ua haujlwm zoo litaphole av nplaum additive FeSiN, txhim kho qhov ceev thiab ua haujlwm ntawm cov khoom siv rau kev yaig.
Hauv cov txheej txheem hlau casting, FeSiN yog siv rau hauv troughing tebchaw thiab ramming refractories, qhov uas nws yog ib qho tseem ceeb los xyuas kom meej cov qauv stability nyob rau hauv tam sim ntawd kub hloov. Kev tsim ntawm nitride theem txo qis tus nqi ntawm slag nkag mus thiab txo qhov kev puas tsuaj saum npoo.
FeSiN kuj tseem siv nyob rau hauv qhov kub thiab txias ntawm theem nrab metallurgy, qhov twg lub sij hawm ntev tshav kub tsis kam thiab tsis kam mus rau cyclic loads yuav tsum tau.
⑤ Kev sib piv ntawm FeSiN qib rau cov ntawv thov kev lag luam
FeSiN 30% nitrogen vs standard FeSiN
Cov version nrog 30% nitrogen muab ntau dua ntawm kev tsim ntawm nitride theem, uas ua rau kom lub zog ntawm cov refractories. Cov qib txheem muaj qhov sib txawv ntawm nitrogen ntau dua thiab cov yam ntxwv tsis ruaj khov.
