Khoom Description
Nyob rau hauv lub ntiaj teb no ntawm cov ntaub ntawv, muaj ib tug tshwj xeeb hav zoov - ferro silicon nitride. Nws yog tsim los ntawm Si3N4, nrog rau cov hlau dawb, tsis muaj nitrided silicon hlau, thiab lwm yam khoom me me.
Silicon hlau nitride muaj ob hom qauv. Refractory qib silicon hlau nitride yog grey dawb (los yog tshuaj yej xim av) hmoov, thaum hlau ua qib silicon hlau nitride yog grey dawb granular khoom.
Cov khoom no muaj ntau yam khoom tshwj xeeb. Ua ntej, nws cov hluav taws kub tsis kam ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv refractory, muaj peev xwm tswj kev ruaj ntseg hauv qhov kub thiab txias. Thib ob, lub zog thiab hardness ntawm silicon hlau nitride kuj ua rau nws siv dav hauv kev lag luam.
Ferro silicon nitride plays lub luag haujlwm tseem ceeb hauv cov txheej txheem steelmaking. Nws tuaj yeem txhim kho qhov zoo ntawm cov hlau thiab txhim kho nws cov kev ua tau zoo.
Hauv lwm qhov chaw, ferro silicon nitride kuj ua lub luag haujlwm tseem ceeb uas tsis tuaj yeem kwv yees. Nws corrosion kuj thiab hnav tsis kam ua rau nws haum rau ntau qhov chaw hnyav.
Hauv cov ntsiab lus, silicon hlau nitride yog cov khoom siv ntau yam, thiab nws cov khoom tshwj xeeb ua rau nws muaj cov ntawv thov tseem ceeb hauv ntau qhov chaw. Nws plays lub luag hauj lwm irreplaceable nyob rau hauv ob qho tib si refractory ntaub ntawv thiab steelmaking.
Cov khoom siv
Ferro silicon nitride feem ntau muaj ob hom: hmoov thiab granular. Powdered silicon hlau nitride yog siv nyob rau hauv clogging av nkos ntawm loj blast furnaces. Nws qhov sib ntxiv tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov av nkos thiab ua kom lub zog ruaj khov ntawm lub qhov cub tawg.
Granular silicon nitride hlau yog tsuas yog siv nyob rau hauv oriented silicon steel los yog lwm yam steel qib uas yuav tsum tau nitrides los txhim kho lub zog, xws li HRB400 steel tuav. Nws qhov muaj nyob tuaj yeem txhim kho lub zog thiab kev ua haujlwm ntawm cov qib steel no.
Ob leeg hmoov thiab granular silicon hlau nitride ua lub luag haujlwm tseem ceeb hauv lawv cov teb.
