Iav tank furnaces sawv cev rau ib qho ntawm qhov xav tau tshaj plaws thermal ib puag ncig hauv kev tsim khoom niaj hnub, ua haujlwm tsis tu ncua rau 8 txog 12 xyoo ntawm qhov kub siab tshaj 1580 degree. Nyob rau hauv qhov kev txhoj puab heev no, molten alkali-silicate iav relentlessly corrodes thiab erodes furnace refractory phab ntsa. Xaiv qhov zoo fused cam khwb cia azs block qib yog ib qho tseem ceeb tshaj plaws engineering kev txiav txim siab rau glassmakers los tiv thaiv kev puas tsuaj ntawm phab ntsa washouts thiab kim kim iav tsis xws luag. Ntawm Topower Refractory, peb tsim thiab ua ntej sib sau ua ke high-density electrofused alumina-zirconia-silica (AZS) refractory blocks engineered kom xa siab tshaj corrosion tsis kam hla ntab, ntim, thiab tshwj xeeb iav melting furnaces thoob ntiaj teb.

Dab tsi yog Fused Cast AZS Block?
A fused cam khwb cia azs block, keeb kwm hu ua electrocast AZS los yog electrofused zircon-corundum refractory, yog tsim los ntawm fusing high-purity calcined alumina thiab hwm zircon xuab zeb (los yog desiliconized zirconia) nyob rau hauv ib qho hluav taws xob arc rauv ntawm kwv yees li 1900 degree. Lub homogenous molten yaj yog tom qab poured rau hauv engineered graphite los yog bonded-xuab zeb pwm, ua raws li los ntawm kev tswj qeeb txias nyob rau hauv insulating kieselguhr bins nyob rau hauv ob peb lub lis piam.
Mineralogically, solidified AZS refractories muaj peb theem sib txawv:
Baddeleyite (Monoclinic ZrO2): Thawj theem crystalline muab superior tshuaj inertia tiv thaiv corrosive molten iav.
Corundum (alpha-Al2O3): Interlocking dendritic skeleton muab tshwj xeeb cov qauv kub load-cov kabmob muaj zog.
Glassy Matrix Phase: High-silica vitreous theem (13% mus rau 16%) uas nyob rau hauv lub crystalline skeleton ciam teb, haum thermal expansion stresses thaum lub cub tawg kub.
Kev sib piv: AZS-33#, AZS-36#, thiab AZS-41#
Kev tiv thaiv corrosion, thermal shock kev ua tau zoo, thiab iav theem exudation kub ntawm AZS blocks nyob ntawm cov ntsiab lus zirconia (ZrO2). Hauv qab no yog cov ntaub ntawv pov thawj kev ntsuas los ntawm peb lub Hoobkas tsim cov qauv:

Nco tseg: Tag nrho cov khoom AZS tau kuaj xyuas qhov tsis txaus ntseeg thiab 100% pob zeb diamond sib tsoo ntawm lub ntsej muag sib koom kom lav seamless iav tank installation.
Casting Void Technologies: RC, TC, RA, thiab VF piav qhia
Thaum lub sij hawm electrofusion solidification, kua contraction generates shrinkage voids (shrinkage kab noj hniav). Kev qhia txog qhov tsim nyog casting kab noj hniav orientation txiav txim lub neej kev pab cuam:
Tsis tu ncua Cast (RC): Lub shrinkage kab noj hniav nyob rau hauv lub Upper central ntim ntawm lub block. Used exclusively in low-wear zones, such as bottom paving under dense sub-layers or upper tuckstones.
Tilted Cast (TC): Cov pwm yog tilted thaum lub sij hawm pouring, hloov lub shrinkage kab noj hniav mus rau ib kawg ntawm lub block. Txhim kho nrog cov khoom hauv qab tig ntsej muag molten iav.
Semi-Void Dawb (RA): Features txo qis qhov khoob nyob ze ntawm qhov chaw sab nrauv, muab lub cev hnyav rau cov phab ntsa sab nrauv.
Tsis pub dawb (VF / WS): Lub taub hau casting yog oversized thiab tag nrho sawn tawm tom qab txias siv pob zeb diamond hlau saws. Qhov tshwm sim yog 100% khoom nrog xoom sab hauv voids, yuav tsum tau rau iav tank sidewall flux kab, electrode blocks, thiab caj pas faces.
Iav Tank Zoning & Xaiv cov khoom
Sib piv cov qib AZS tshwj xeeb thiab cov txheej txheem casting rau qhov sib txawv ntawm qhov chaw ua kom sov ua kom lub tank ua kom lub neej ntev dua thaum txhim kho cov peev txheej refractory:
1. Melting Tank Sidewall & Flux Kab
Cov iav-theem kab (flux kab) muaj kev kub siab thermal convection, mechanical nto nthwv dej, thiab concentrated tshuaj corrosion. Ntawm no,AZS-41# Tsis pub dawb (VF)blocks yog yuav tsum tau. Lub 40% zirconia concentration tsim ntom baddeleyite crystalline chains uas tiv thaiv cov iav ntxuav, tiv thaiv ntxov ntxov peb-theem ciam teb undercut.
2. caj pas thiab submerged hla
Lub caj pas txuas lub melting tank mus rau qhov kawg ua hauj lwm, tuav high-ceev molten iav ntws. Lub cheeb tsam tseem ceeb no xav tauAZS-41# Tsis pub dawb (VF)nrog pob zeb diamond-hauv av mating nto kom tshem tawm kev sib koom tes yaig thiab vortex drilling.
3. Paving thiab hauv qab kev tsim kho
Rau lub tank hauv qab paving,AZS-33# los yog AZS-36# (TC or VF)blocks yog ntsia rau ntau txheej av nplaum flux sub-hearths los yogsiab alumina cibfoundations, nquag txhawb nqa los ntawmcalcium aluminate cementcastable sealing txheej.
4. Superstructure, Crown Tuckstones & Breastwalls
Cov phab ntsa, qhov chaw nres nkoj caj dab, thiab tuckstones fim alkali vapors (Na2O, K2O) thiab batch plua plav nqa ntau dua li cov kua iav ncaj qha.AZS-33# (Regular or RA)muab zoo alkali vapor tsis kam thiab thermal spalling durability yam tsis muaj tus nqi hwm ntawm qib siab zirconia.
Iav Phase Exudation & Kev Tiv Thaiv Tsis Zoo
Ib qho tseem ceeb tshaj plaws kev txiav txim siab rau iav engineers yog iav theem exudation:
1. Cov txheej txheem Exudation
Nyob nruab nrab ntawm 1300℃thiab 1500 degree, lub high-silica vitreous theem nyob nruab nrab ntawm baddeleyite thiab corundum nplej expands thiab tawm hws tawm mus rau lub block nto nyob rau hauv capillary siab. Yog hais tias cov kua exuded no muaj cov roj yaj los yog impurities, nws detaches mus rau hauv lub khob yaj, tsim refractory knot defects, miv-scratches, thiab noob npuas.
2. Kev Ntsuas Zoo
Ntawm Topower Refractory, peb tswj nruj tswj hwm alkali (Na2O<= 1.3%) and iron oxide (Fe2O3 <= 0.10%) raw material limits. Lowering flux impurities increases the viscosity of the interstitial glass phase, raising the exudation starting temperature above 1420°C to 1450°C. This ensures clean, defect-free glass melting during initial furnace commissioning.
Pre-Assembly, Pob Zeb Diamond Machining & Sourcing
Vim hais tias iav tank tsim tso cai rau qhov sib koom ua ke tsis dav dua 0.5 hli, kev ua cov refractory meej yog qhov tseem ceeb:
Pob zeb diamond Machining: Tag nrho cov molten-contact thaiv ntsej muag undergo precision CNC pob zeb diamond planers thiab nto grinders kom paub meej meej flatness thiab txoj cai-lub kaum ntse ntse.
1: 1 Lub Hoobkas Qhuav Pre-Assembly: Ua ntej lub thawv ntim khoom, peb cov kws tshaj lij sib sau ua ke tag nrho lub tank sidewalls, caj pas, thiab doghouse arches ntawm qib tshuaj ntsuam pem teb hauv peb lub hoobkas. Txhua qhov thaiv yog suav nrog, sau nrog cov duab kos duab, thiab pom zoo los ntawm cov neeg soj ntsuam xyuas.
Export Ntim: Txhua lub tshuab thaiv yog qhwv hauv cov dej tsis muaj pov thawj, ruaj nrog steel banding, thiab ntim rau hauv kev cai-tsim muaj zog fumigated ntoo crates.
Transparent Sourcing: Nqe & Yuav Ua Li Cas
Topower Refractory muab kev txhawb nqa engineering rau kev tsim lub cub tawg tshiab, kho qhov txias, thiab hloov kub kub kub:

Cov lus nug nquag
Vim li cas AZS-41# nyiam rau iav melting tank sidewalls tshaj AZS-33#?
AZS-41# muaj ntau dua 40% ZrO2, tsim kom muaj kev sib txuas txuas ntxiv ntawm cov khoom siv hluav taws xob tsis zoo-resistant baddeleyite. Nyob rau hauv cov kab hluav taws xob sab saud uas cov iav convective tam sim no thiab cov tshuaj lom neeg tawg tau siab tshaj, AZS-41# muab txog li 40% lub neej ua haujlwm ntev dua AZS-33#, tiv thaiv lub tank tsis ua haujlwm ntxov.
Dab tsi ua rau hlwv thiab pob zeb tsis xws luag los ntawm AZS refractory blocks?
Cov pob zeb thiab pob zeb tsis xws luag feem ntau yog los ntawm cov iav ua ntej lub sij hawm exudation los yog ntxhib corundum grain ntxuav tawm. Thaum cov hlau los yog cov alkali siab ua kom tawm hws tawm ntawm lawv cov vitreous theem ntawm qhov kub thiab txias, cov kua nplaum ua npuas thiab cov pob txha tsis muaj zog hauv cov iav ribbon. Topower tuav Fe2O3 qis dua 0.10% txhawm rau tshem tawm qhov kev pheej hmoo no.
Yuav fused cam khwb cia AZS blocks raug txiav los yog drilled on-site thaum lub installation?
Vim lub siab baddeleyite siv lead ua hardness (Mohs 8.5 txog 9), on-site qhuav txiav yog ze li ntawm tsis yooj yim sua thiab txaus ntshai thermal shock tawg. Tag nrho cov block trimming, beveling, thiab qhov drilling (xws li bubbler lossis electrode qhib) yuav tsum ua kom tiav ntawm peb lub Hoobkas siv cov cuab yeej siv tshuab pob zeb diamond-tipped nrog cov dej txias tas li.
