Ferro Silicon Nitride Rau Taphole Clay

Ferro Silicon Nitride rau Taphole Clay yog ib qho tshwj xeeb inorganic uas tsis yog -nws yog xim hlau additive engineered los txhim kho qhov kev ua tau zoo ntawm blast furnace taphole av nplaum ( phom av nplaum). Nrog rau grey rau grey-dub hmoov los yog granular daim ntawv, no multi-component compound muaj silicon nitride (Si₃N₄), hlau silicides (Fe₃Si, Fe₂Si), thiab trace silicon carbide (SiC), featuring tswj cov ntsiab lus hlau compatibility (17%){ av nplaum formulations. Tsim los rau siab heev- qhov kub thiab txias ib puag ncig ntawm blast furnace tapholes, nws txhim kho rab phom av nplaum lub zog, yaig tsis kam, qhib kev ua tau zoo, thiab tus nqi-kev ua tau zoo-ua rau nws yog ib qho tseem ceeb ntxiv rau cov tuam txhab steelmaking nrhiav kev ua haujlwm ruaj khov thiab txo cov nqi tu.

FeSi nitride, nrog nws qhov sib xyaw tshwj xeeb ntawm silicon nitride (Si₃N₄), hlau (Fe), thiab silicon (Si), ua raws li kev ua tau zoo hauv cov av nplaum. Thaum ntxiv rau hauv cov proportions meej (feem ntau 5-15% ntawm cov av nplaum sib tov), ​​nws txhim kho cov khoom tseem ceeb xws li:

 Siab - qhov kub thiab txias (tso kev ncaj ncees ntawm 1500-1600 degree)
 Resistance rau molten hlau / slag yaig
 Thermal shock resistance (nrog rau kev kub ceev ceev)
 Tswj sintering los tiv thaiv taphole tawg

 Chemical Composition (Qib- paub meej)

Peb Ferro Silicon Nitride rau Taphole Clay ua raws li cov qauv nruj nruj kom ntseeg tau tias kev ua haujlwm zoo ib yam hauv cov ntawv siv phom av nplaum. Hauv qab no yog cov ncauj lus kom ntxaws tshuaj muaj pes tsawg leeg (tag nrho cov txiaj ntsig yog qhov hnyav feem pua, %):

 Lub cev muaj zog & Customization

Cov Kev Xaiv Zoo:Hmoov, Granules, Lump (tsim rau taphole av nplaum sib tov yuav tsum)
Qhov ntau thiab tsawg:0 ~ 3mm, 10 ~ 60mm (tus qauv); Qhov ntau thiab tsawg muaj (1 ~ 10mm, 10 ~ 50mm, 100mesh, 200mesh, thiab lwm yam)
Ntim:Lub hnab ntim (nqus dej- tiv taus, tus qauv) lossis kev ntim khoom ntim (cov nruas kaw, lub hnab me me) los tiv thaiv oxidation thiab nqus dej noo thaum khaws cia / thauj
Qhov tsos:Grey rau grey-dub hmoov / granules (tsau dua li cov ntshiab silicon nitride vim yog cov ntsiab lus hlau)
Qhov tseem ceeb:Siab - kub stability (resist decomposition hauv qab 1400 degree), tau tshaj txhua hom taphole av nplaum formulations

1. Superior Erosion Resistance

Molten hlau thiab slag (1400-1500 degree) ua rau hnyav hnyav ntawm cov av nplaum. FeSi3N4 reacts nrog slag los tsim ib txheej tiv thaiv ntom ntom ntawm calcium silicate (CaSiO₃) thiab magnesium silicate (MgSiO₃), uas:
 Txo tus nqi yaig los ntawm 30-40% piv rau av nplaum nrogsilicon carbide
 Tswj taphole txoj kab uas hla stability (tseem ceeb rau kev tswj cov hlau ntws)
 Txuas lub neej kev pabcuam taphole los ntawm 8-12 teev mus rau 16-24 teev nyob rau hauv nruab nrab qhov cub tawg (1000-2000 m³)

2. Siab -Tsub Muaj Zog Retention

Ntawm qhov kub ntawm qhov cub ua haujlwm kub, ntau lub refractories poob lub zog. Ferro silicon nitride's Si₃N₄ theem khaws cia 80% ntawm nws chav - qhov kub thiab txias ntawm 1500 degree, kom ntseeg tau cov av nplaum:
 Resistant deformation nyob rau hauv molten hlau siab (tiv thaiv "bulging" tapholes)
 Ua kom muaj kev ncaj ncees thaum lub sij hawm rov tapping cycles (6-8 zaug ib hnub twg)
 Txo "blowouts" tshwm sim los ntawm av nplaum tawg

3. Tswj Sintering & Thermal Shock Resistance

Ferro silicon nitride tswj cov av nplaum txheej txheem sintering, tiv thaiv kom tsis txhob ntau dhau los yog tawg:
 Txo sintering kub los ntawm 50-100 degree, txo lub zog noj thaum lub sij hawm ua av nplaum
 Cov ntaub ntawv microcracks uas nqus thermal stress (los ntawm 1500℃rau ambient kub ntawm tappings)
 Minimizes spalling (flake detachment) los ntawm 50% piv rau av nplaum nrog ntshiab silicon nitride

4. Tus nqi -Kev ua tau zoo

Thaum cov ntshiab silicon nitride (Si₃N₄) muaj cov khoom zoo sib xws, nitride ferro silicon muab tus nqi zoo dua -kev ua tau zoo piv:
 30-50% pheej yig dua li ntshiab silicon nitride (vim cov ntsiab lus hlau txo cov nqi raw khoom)
 Cov kev xav tau tsawg dua (5-15% vs . 8-20% rau Si₃N₄) kom ua tiav qhov kev ua tau zoo
 Txo cov nqi tu tag nrho ntawm taphole los ntawm 20-25% ib xyoos ib zaug rau lub qhov cub tawg

5. Compatibility nrog av nplaum formulations

Ferro silicon nitride integrates seamlessly nrog ntau taphole av nplaum Cheebtsam (alumina, graphite, suab), kom ntseeg tau tias:
 Uniform dispersion (tseem ceeb rau kev ua tau zoo ib yam)
 Tsis muaj kev phiv tshuaj nrog cov binders (piv txwv li, phenolic resin)
 Kev hloov kho rau qhov cub- tej yam kev mob tshwj xeeb (piv txwv li, siab -slag vs. siab- hlau piv)
