Daim ntawv thov ntawmferrosilicon nitride hmoovhauv phom av nplaum
Ferrosilicon nitride yog cov khoom siv feem ntau siv hauv cov hlau smelting vim nws muaj nitrogen thiab tseem yog ib qho tseem ceeb raw khoom rau smelting high-nitrogen steel. Ferrosilicon nitride kuj tseem muaj qhov kub thiab txias tsis kam thiab muaj cov ntawv thov zoo hauv qee cov ntaub ntawv kub kub refractory. Cannon av nplaum yog siv los thaiv lub taphole. Cov hlau molten nyob rau hauv lub taphole tsis tsuas yog muaj zog corrosive zog tab sis kuj muaj qhov kub thiab txias. Daim ntawv thov ntawm ferrosilicon nitride yuav tsis tsuas yog tsis cuam tshuam qhov muaj pes tsawg leeg ntawm cov hlau molten, tab sis kuj txhim kho Txhim kho qhov kub-kub kuj ntawm rab phom av nplaum.

Cannon av nplaum yog cov khoom siv carbon-bonded refractory rau blast furnace tapholes. Raws li blast furnaces loj hlob mus rau qhov loj thiab ntev lifespan, cannon av nplaum tau hloov los ntawm ib tug yooj yim consumable refractory khoom mus rau ib tug functional refractory khoom. Txij li thaum tsuas yog nce SiC cov ntsiab lus hauv cov av nkos los txhim kho nws qhov kub thiab txias tsis tuaj yeem ua tau raws li qhov yuav tsum tau siv rau kev siv hluav taws xob tawg, ferrosilicon nitride, yog hom tshiab ntawm cov khoom siv tsis-oxide refractory raw khoom, muaj cov khoom zoo sintering, tshuaj stability, thiab siab. thermal tsis kam. lub xeev lub zog thiab thermal conductivity.
Piv nrog rau qhov sib ntxiv ntawm SiC los yog Si3N4 rau hauv cov av nkos, qhov kub-kub flexural zog ntawm cov av nkos ntxiv rau hauv cov av nkos tau raug txhim kho mus rau qhov sib txawv ntawm qhov kub thiab txias; thiab Fe-Si3N4 tuaj yeem decompose ntawm qhov kub thiab txias los tsim N2 roj. Tsim diffuse micro-pores, uas yog qhov zoo rau kev txhim kho cov drillability ntawm rab phom av nplaum.
Tus yuam sij rau daim ntawv thov ntawm Fe-Si3N4 nyob rau hauv pothole av nplaum yog txawv ntawm SiC thiab Si3N4 nyob rau hauv lub xub ntiag ntawm ductile particle reinforcement Fe thiab intermetallic compound Fe3Si nyob rau hauv Fe-Si3N4. Fe3Si txhawb kev sintering ntawm pothole av nkos thiab kev hloov ntawm -Si3N4 rau -Si3N4, txhim kho lub zog sib txuas ntawm oxide / non-oxide.
Los ntawm cov kev soj ntsuam luv luv saum toj no, kuv ntseeg tias txhua tus neeg muaj kev nkag siab zoo dua ntawm kev ua haujlwm ntawm ferrosilicon nitride hauv cov av nplaum av. Tom qab ferrosilicon nitride ntxiv rau cannon av nplaum, nws yuav hnov mob nrog cov molecules hauv cannon av nplaum, yog li txhim kho kev ua haujlwm ntawm cov av nplaum cannon. Lub zog sib txuas yog qhov tsim nyog rau kev txhim kho kev ua haujlwm ntawm cannon av nplaum. Ferrosilicon nitride yog ib yam khoom uas tau maj mam siv dav hauv khw. Yog tias koj xav paub ntau ntxiv lossis xav yuav, thov hu rau peb.
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.
