Ferrosilicon Nitride (Si3N4 75-80%)

Ferrosilicon Nitride (feem ntau qhia tias yog fe₃sin₄ lossis fesiₓnᵧ) yog cov ntawv sau tshiab ferrro alloy tsim los ntawm qhov siab - kub ntawmFERRO Siliconthiab nitrogen. Nws ua ke qhov siab - qhov kub thiab txias ntawm cov khoom siv hlau hauv methollurgy, cov ntaub ntawv hauv tsev, thiab cov khoom siv hauv tsev, thiab refractories. Nws cov tseem ceeb tus nqi nyob hauv nws qhov siab- kub ua hauj, thiab qis kev nthuav dav, hais qhov kev ua tau zoo luv ntawm cov ntaub ntawv ua haujlwm hauv kev ua haujlwm dhau los.

Ferrosilicon nitrideyog hom tshiab ntawm cov khoom siv hluavtaws cov khoom siv hluavtaws, nrogSi3n4Raws li lub ntsiab tivthaiv, SI3N4 cov ntsiab lus ntawm txog 75% -80%, thiab tseem muaj 12% FE, SI dawb tsis ntau tshaj li 1%. Kev Lag Luam Fesin rau Refractory yog xim greyish lossis xim av, thiab fesi3n4 rau steelmaking yog greyish dawb granular. Vim tias nws muaj cov khoom siv si33n4, nws muaj qee cov khoom zoo ntawm SI3N4, xws li kev nthuav dav hluav taws xob, muaj kev nthuav dav zoo, thiab lwm yam.

Cov khoom siv refractory

Nws yog ib qho tseem ceeb tivthaiv ntawm lub zog kom sov cov coom dej Channel Castables thiab Taphole av, uas tuaj yeem txhim kho cov khoom siv hluav taws xob tsis kam thiab cov khoom siv tshuab hluav taws xob; Nws tuaj yeem txhim kho lub zog kub kub, oxidation tsis kam, corrosion tsis kam thiab nplawm cov av nkos muaj qhov ruaj khov zoo dua thiab ntsuas kub.

Steelmaking

Mas siv rau kev taw qhia cov kab zauv lossis lwm hom steel lossis lwm hom steel uas siv cov nitrides kom nce lub zog, xws li HRB400 steel tuav. Nws tuaj yeem tsim cov nitrogen rau Molten hlau, uas ua lub luag haujlwm ntawm cov nplej ua kom zoo thiab muaj zog thiab tawv ntawm cov hlau.

Deoxidation nyhuv

Deoxidizers:

nyiamFerrosilicon Deagidation, cov silicon dioxide generated los ntawm nws deoxidation cov tshuaj tiv thaiv muaj qhov yooj yim kom ntab thiab tshem tawm hauv cov hlau ua ke, cuam tshuam rau qhov zoo ntawm cov hlau. Txawm hais tias txhuas muaj lub peev xwm dazidation muaj zog, nws cov kev nqus tshwj xeeb yog cov me dua li ntawm cov hlau molten. Nws yog ib qho yooj yim rau oxidize thiab hlawv rau saum npoo ntawm molten hlau, nrog tus nqi siv tsawg. Tsis tas li ntawd, cov khoom lag luam deoxation aluminium txhuas muaj lub siab tawv thiab muaj zog, uas cuam tshuam rau cov xim ntawm Molten Steel thiab cov txheej txheem ntawm cov cuab yeej.Puas deoxidizersxws liSilicon Aluminium Barium CalciumMuaj cov nyhim zoo deoxidation zoo, uas tuaj yeem txo cov ntsiab lus oxygen hauv qib qis dua, tab sis tej zaum yuav muaj kev txwv hauv deoxidation ntawm qee qhov tshwj xeeb ntawm cov hlau.

Ferrosilicon Nitride:

Nws tuaj yeem hnov ​​mob nrog oxygen nyob rau hauv molten steel los tsim cov oxygen, thiab cov nitrogen tsim tawm, thiab tuaj yeem txhim kho cov roj av zoo.

Deoxidation Ceev

Cov ib txwm deoxidization:

Tom qab ntxiv ib txwm muajDeagidizersxws liferrosiliconThiab txhuas mus rau Molten hlau, nws siv qee lub sijhawm thiab nplawm cov mob kom nrawm nrog oxygen, thiab deoxidation yog qeeb. Piv txwv li, thaum txhuas yog deoxidized, vim nws cov kev nqus me me, nws yog qhov yooj yim kom ntab ntawm cov tshuaj tsw qab thiab oxidits thiab oxidete disavenation thiab deoxidation ceev.

Ferrosilicon Nitride:

Ferro silicon nitride dissolves sai sai nyob rau hauv Molten hlau thiab tuaj yeem nrawm tus txheej txheem Deagidation, txhim kho cov txheej txheem Deagidation, txhim kho kev ua haujlwm zoo, txhim kho lub sijhawm steelmaking luv.

Txhim Kho

Cov ib txwm deoxidization:

Muaj ib txwm deoxidizers xws li composite deoxidizers xws li Ferro Silicon,, lub luag haujlwm tseem sib xws, thiab lub luag haujlwm tseem ceeb tseem yog deoxidation.

Ferrosilicon Nitride:

Ntxiv rau kom muaj cov khoom lag luam deoxidation zoo, Ferro Silicon Nitride tseem tuaj yeem muab cov khoom lag luam nitrogen rau Molten Steel thiab ua si lub luag haujlwm hauv nitrogen cia. Nyob rau tib lub sijhawm, lub thawv silicon hauv nws kuj tuaj yeem ua lub luag haujlwm ntawm deoxidation thiab kev cia siab, uas pab txhawm rau txhim kho kev ua haujlwm ntawm cov hlau.

Rau cov ntawv thov refractory:Tsawg dua los yog sib npaug rau 0.074 hli (-200 mesh) yog qhov zoo tshaj plaws; Rau cov haujlwm siab dua, tsawg dua los yog sib npaug rau 0.045 hli (-325 mesh)

Rau steelmaking:3-10 hli lossis 10-50 mm hais yog nyiam dua rau kev tswj hwm zoo dua thiab tawm tswv yim tswj.
