Silica Refractory Cib

Taw qhia

 

Silica cib yog cov khoom siv refractory nrog SiO₂ cov ntsiab lus ntau dua 93%, tsim los siv cov khoom siv silica nrog cov ntsiab lus SiO₂ tsis tsawg dua 96%. Nws yog tsim los ntawm cov txheej txheem xws li kev sib tov, molding, ziab, thiab tua, nrog rau cov ntxhia pob zeb thiab cov binders ntxiv thaum lub sij hawm tsim khoom. Qhov siab dua SiO₂ cov ntsiab lus, qhov siab dua qhov refractoriness. Additives xws li Fe₂O₃ thiab CaO ua raws li cov ntxhia pob zeb, thaum impurities xws li MgO, K₂O, thiab Na₂O degrade lub refractory qhov kub-kub kev ua tau zoo.

Cov ntxhia theem ntawm silica cib feem ntau yog tridymite thiab cristobalite, nrog me me ntawm residual quartz, ib theem iav tsim nyob rau hauv qhov kub thiab txias, thiab lwm yam txheej txheem complex. True density is a key indicator of crystalline transformation: a lower true density indicates a higher content of tridymite and cristobalite, less residual quartz, lower residual expansion, and slower strength degradation during use.

Silica cib yog cov khoom siv acidic refractory resistant rau corrosion los ntawm acidic slags los yog cov kev daws teeb meem tab sis yooj yim rau kev tawm tsam los ntawm alkaline tshuaj. Nws nthuav tawm lub siab load-bearing softening kub, feem ntau yog li ntawm 1640℃mus rau 1680 degree. Saum toj no 300 degree, nws tuav lub ntim stability ze rau nws melting point. Thaum rhuab mus rau 1450 degree, nws undergoes tag nrho ntim expansion ntawm 1.5% -2.2%, ua rau nws haum rau daim ntaub ntawv xws li:

'Carbonization Chambers ntawm coke qhov cub

'ru tsev thiab pas dej ua ke phab ntsa ntawm iav kilns

'High-temperature load-bearing Cheebtsam ntawm kub blast furnaces thiab charcoal roasters

Cov khoom no ua rau silica cib haum rau hauv ob sab phlu thermal kilns hauv ntau yam lag luam.

Qhov zoo

 

1. High Refractoriness thiab Load-Bearing Capacity
Silica bricks muaj siab refractoriness, feem ntau yog li ntawm 1670-1710 degree, thiab ib tug load softening kub ntawm 1640-1680 degree. Qhov no tso cai rau lawv kom muaj kev ncaj ncees nyob rau hauv high-temperature thiab hnyav-load tej yam kev mob, ua rau lawv haum rau cov khoom tseem ceeb nyob rau hauv kilns thiab furnaces.
2. Zoo heev Volume Stability ntawm qhov kub thiab txias
Tshaj li 300 degree, silica cib qhia qhov hloov pauv me me nyob ze rau lawv qhov melting point. When heated to 1450℃, they undergo a controlled total volume expansion (1.5%–2.2%), which helps form a dense, tight masonry structure and prevents thermal stress-induced cracking.
3. Kev tiv thaiv zoo tshaj rau Acid Media

Raws li acidic refractories, silica bricks yog heev resistant rau corrosion los ntawm acidic slags, kev daws, thiab gases (xws li, SiO₂-nplua nuj melts nyob rau hauv iav los yog steel ntau lawm). Qhov no ua rau lawv zoo tagnrho rau cov pa roj carbonization chambers hauv coke ncu, nrog rau cov iav kiln ru tsev thiab phab ntsa hauv pas dej.

4. Tsawg Thermal Expansion Coefficient
Silica bricks muaj cov thermal expansion coefficient tsawg, txo qhov kev pheej hmoo ntawm thermal spalling tshwm sim los ntawm kub hloov pauv sai. Qhov no txhim kho lawv cov kav ntev hauv ib puag ncig nrog cov cua sov thiab cua txias.
5. Zoo thermal conductivity

Piv nrog rau lwm cov refractories (xws li, fireclay cib), silica cib muab cov thermal conductivity ntau dua, ua kom muaj cua sov hloov mus rau hauv cov ntawv thov xws li kub kub blast furnace regenerators thiab charcoal roasters.

Cov khoom siv raw

Silica (quartz) nrog qhov tsawg kawg ntawm SiO₂ cov ntsiab lus ntawm 96% yog thawj cov khoom siv raw. Cov impurities xws li Al₂O₃, Fe₂O₃, CaO, MgO, K₂O, thiab Na₂O yog nruj me ntsis tswj kom tsawg dua los yog sib npaug li 4% kom tsis txhob degrading high-temperature kev ua tau zoo.

Raw khoom npaj:

Silica raw cov ntaub ntawv xws li vein quartz, quartzite, thiab quartz sandstone raug xaiv rau lawv cov purity siab, tsis muaj impurity cov ntsiab lus, thiab cov ntsiab lus hlau tsawg. Cov khib nyiab silica cib lossis hmoov tuaj yeem raug crushed thiab tshuaj xyuas kom rov siv dua li cov khoom siv raw. Mineralizers thiab burnout additives kuj suav nrog:

Cov mineralizers:Alumina, hlau oxide, magnesium oxide

Burnout additives:Carbon hmoov, graphite

Moulding:

Mechanical Moulding:Cov ntaub ntawv raw khoom tau muab sib xyaw rau hauv qhov sib piv thiab mechanically pressed siv cib presses los yog hydraulic presses. Txoj kev no yog qhov ua tau zoo thiab raug nqi, ua rau nws tsim nyog rau kev tsim khoom loj.

Phau ntawv Molding:Cov cib yog xuas tes ua los ntawm cov pwm, muab qhov yooj yim rau cov duab thiab qhov ntau thiab tsawg. Qhov no yog qhov zoo tagnrho rau cov khoom me me lossis cov ntawv tshwj xeeb.

Kev ziab:

Tom qab molding, cib blanks yuav tsum tau qhuav kom tshem tawm noo noo. Kev ziab yuav tsum tau ua tib zoo tswj raws li tus nqi, qhov kub thiab txias, thiab qhov cua kom tiv thaiv kev tawg lossis deformation vim qhov ziab tsis sib xws.

Kev tua hluav taws:

Thaum tshav kub kub:Qhuav cib blanks yog maj mam rhuab nyob rau hauv ib lub kiln kom tiv thaiv thermal shock-induced cracking.

Soaking theem:Qhov kub thiab txias tas li yog tswj xyuas kom ua tiav SiO₂ polymorphic transformation, txhim kho cov khoom ntom thiab lub zog.

Theem cua txias:Kev ua kom txias qeeb txo qhov kev ntxhov siab sab hauv los ntawm kev hloov kub ceev.

Silica cib yog qhov zoo rau cov kev siv tshwj xeeb vim lawv cov khoom tshwj xeeb:

Coke qhov cub:Siv rau hauv cov khoom xws li carbonization thiab combustion chambers, silica bricks tiv taus kub, siab, thiab tshuaj yaig, ua kom lub qhov cub coke ua haujlwm zoo.

Iav Kilns: Silica bricks yog dav siv nyob rau hauv lub melting cheeb tsam, clarification cheeb tsam, thiab regenerator ntawm iav kilns. Lawv tiv thaiv corrosion los ntawm molten iav thiab kub-kub los, ncua lub kiln lub neej kev pab cuam.

Kub Blast Furnaces:Nyob rau hauv qhov kub thiab txias zoo li lub qhov rooj thiab lub qhov cub phab ntsa, silica cib muab qhov kub thiab txias zog thiab ntim ruaj khov, ua kom lub qhov cub ua haujlwm tau zoo.

Hlau thiab Non-ferrous Metallurgy:Hauv cov kua qaub qhib-hearth thiab hluav taws xob furnaces, silica cib ua cov ntaub ntawv hauv ob sab phlu thiab phab ntsa, tiv taus acidic slag corrosion thiab kub-kub yaig.

Ceramic Kiln:Siv rau hauv cov khoom xws li lub ru tsev thiab phab ntsa, silica cib tiv taus qhov kub thiab txias thermal hloov pauv thaum lub sij hawm hluav taws xob ceramic, tswj cov khoom zoo.

Qhov zoo:

High Refractoriness:1690-1710 degree, haum rau huab cua kub ib puag ncig

Acid Resistance:Withstands acidic slag corrosion, zoo tagnrho rau acid-based industrial kilns

High-Temperature Strength:Khaws cov qauv kev ruaj ntseg nyob rau hauv lub sij hawm thermal kev nyuaj siab

Zoo heev thermal conductivity:Txhawb nqa kev hloov pauv kom zoo thiab kub tsis sib xws

Volume Stability:Minimizes deformation thaum lub sijhawm ua haujlwm kub kub
