E-iav (alkali-dawb fiberglass)ntau lawm nyob rau hauv tank furnaces yog ib tug complex, high-temperature melting txheej txheem. Lub melting kub profile yog ib qho tseem ceeb ntawm cov txheej txheem tswj cov ntsiab lus, ncaj qha cuam tshuam cov iav zoo, melting efficiency, lub zog noj, rauv lub neej, thiab qhov kawg fiber ntau. Qhov ntsuas kub no feem ntau yog ua tiav los ntawm kev kho cov yam ntxwv ntawm cov nplaim taws thiab kev txhawb nqa hluav taws xob.

I. Melting Kub ntawm E-iav

1. Melting Temperature Range:

Qhov ua tiav melting, qhia meej, thiab homogenization ntawm E-iav feem ntau yuav tsum tau kub siab heev. Qhov feem ntau melting tsam (kub qhov chaw) kub feem ntau yog li ntawm 1500 ° C mus rau 1600 ° C.

Lub hom phiaj kub tshwj xeeb nyob ntawm:

* Batch Composition: Cov qauv tsim tshwj xeeb (xws li, muaj fluorine, cov ntsiab lus siab / qis boron, muaj cov titanium) cuam tshuam cov yam ntxwv ntawm melting.

* Kev tsim hluav taws xob: Lub tshuab hluav taws xob hom, qhov loj me, kev tiv thaiv kev ua haujlwm zoo, thiab kev teeb tsa lub qhov cub.

* Lub Hom Phiaj Ntau Lawm: Xav tau melting tus nqi thiab iav zoo yuav tsum tau.

* Cov Khoom Siv Refractory: Tus nqi corrosion ntawm cov ntaub ntawv refractory ntawm qhov kub siab txwv qhov kub siab.

Qhov fining cheeb tsam kub feem ntau yog me ntsis qis dua qhov kub qhov chaw (kwv yees li 20-50 ° C qis dua) kom yooj yim tshem tawm npuas thiab iav homogenization.

Qhov ua hauj lwm kawg (forehearth) kub yog qhov qis dua (feem ntau 1200 ° C - 1350 ° C), coj cov iav yaj mus rau qhov tsim nyog viscosity thiab ruaj khov rau kev kos duab.

2. Qhov tseem ceeb ntawm kev tswj qhov kub thiab txias:

* Melting Efficiency: Kev kub siab txaus yog qhov tseem ceeb rau kev ua kom tiav cov tshuaj tiv thaiv ntawm cov ntaub ntawv batch (quartz xuab zeb, pyrophyllite, boric acid / colemanite, limestone, thiab lwm yam), tag nrho cov xuab zeb yaj, thiab cov roj tso tawm. Qhov kub tsis txaus tuaj yeem ua rau "cov khoom siv raw" seem (cov khoom tsis muaj quartz), pob zeb, thiab npuas ntau ntxiv.

* Cov iav zoo: Cov kub kub txhawb kom pom tseeb thiab homogenization ntawm cov iav yaj, txo qhov tsis xws luag xws li hlua, npuas, thiab pob zeb. Cov teeb meem no cuam tshuam rau fiber ntau lub zog, tawg tus nqi, thiab txuas ntxiv.

* Viscosity: Kub ncaj qha cuam tshuam lub viscosity ntawm iav yaj. Kev kos duab fiber ntau xav kom cov iav yaj kom nyob rau hauv ib qho viscosity ntau yam.

* Cov Khoom Siv Hluav Taws Xob Corrosion: Kub kub ntau dhau ua rau cov khoom siv hluav taws xob ua kom sov (tshwj xeeb tshaj yog cov khoom siv hluav taws xob AZS), ua rau lub cub tawg luv thiab muaj peev xwm qhia cov pob zeb refractory.

* Kev siv hluav taws xob: Kev tswj xyuas qhov kub thiab txias yog qhov tseem ceeb ntawm kev siv hluav taws xob hauv lub tank furnaces (feem ntau suav txog ntau dua 60% ntawm tag nrho cov khoom siv hluav taws xob). Kev tswj qhov kub thiab txias kom tsis txhob kub dhau yog qhov tseem ceeb rau kev txuag hluav taws xob.

II. Kev cai nplaim taws

Kev tswj cov nplaim hluav taws yog ib qho tseem ceeb ntawm kev tswj xyuas qhov kub thiab txias, ua kom muaj txiaj ntsig zoo, thiab tiv thaiv cov qauv hluav taws xob (tshwj xeeb tshaj yog cov yas). Nws lub hom phiaj tseem ceeb yog los tsim kom muaj qhov chaw zoo tshaj plaws kub thiab cua.

1. Cov Txheej Txheem Tseem Ceeb:

* Roj-rau-Air Ratio (Stoichiometric Ratio) / Oxygen-rau-Fuel Ratio (rau oxy-fuel systems):

* Lub hom phiaj: Ua tiav kev sib xyaw ua ke. Tsis tiav combustion khib nyiab roj, txo cov nplaim hluav taws kub, ua rau cov pa luam yeeb dub (soot) uas paug cov iav yaj, thiab clogs regenerators / heat exchangers. Cov huab cua ntau dhau tshem tawm cov cua kub tseem ceeb, txo cov thermal efficiency, thiab tuaj yeem ua kom cov yas oxidation corrosion.

* Kev Kho Kom Zoo: Tswj cov huab cua-rau-roj piv tau raws li qhov ntsuas roj flue (O₂, CO ntsiab lus).E-iavtank furnaces feem ntau tuav cov pa roj O₂ cov ntsiab lus nyob ib ncig ntawm 1-3% (me ntsis zoo siab combustion).

* Kev cuam tshuam ntawm huab cua: Cov huab cua-rau-roj piv kuj cuam tshuam rau lub qhov cub cua (oxidizing lossis txo), uas muaj qhov cuam tshuam tsis zoo rau tus cwj pwm ntawm qee yam khoom siv (xws li hlau) thiab iav xim. Txawm li cas los xij, rau E-iav (yuav tsum muaj xim tsis pom tseeb), qhov cuam tshuam no kuj yog me.

* Nplaim ntev thiab zoo li:

* Lub Hom Phiaj: Tsim cov nplaim hluav taws uas npog cov nplaum nplaum, muaj qee yam rigidity, thiab muaj kev sib kis tau zoo.

* Nplaim ntev vs. Nplaim luv:

* Ntev Nplaim: Npog ib cheeb tsam loj, qhov kub thiab txias yog qhov sib xws, thiab ua rau muaj thermal poob qis rau lub kaus mom. Txawm li cas los xij, qhov ntsuas kub hauv zos yuav tsis siab txaus, thiab kev nkag mus rau hauv thaj tsam "drilling" yuav tsis txaus.

* Cov nplaim taws luv: Muaj zog rigidity, siab kub hauv zos, muaj zog nkag mus rau hauv batch txheej, ua rau kom nrawm nrawm ntawm "cov ntaub ntawv raw." Txawm li cas los xij, kev pab them nqi tsis sib xws, yooj yim ua rau muaj cua sov hauv cheeb tsam (ntau tshaj qhov kub ntawm qhov chaw), thiab tseem ceeb thermal shock rau lub kaus mom thiab lub mis phab ntsa.

* Kev hloov kho: Ua tiav los ntawm kev kho lub kaum sab xis ntawm lub tshuab hluav taws xob, roj / cua tawm tshaj tawm (momentum ratio), thiab kev siv zog. Niaj hnub nimno tank furnaces feem ntau siv ntau theem adjustable burners.

* Nplaim taw qhia (lub kaum sab xis):

* Lub hom phiaj: Hloov cov cua sov kom zoo rau cov batch thiab iav yaj saum npoo, tsis txhob cuam tshuam cov nplaim taws ncaj qha rau ntawm phab ntsa lossis lub mis.

* Kho: Kho lub suab (ntu) thiab yaw (kab rov tav) lub kaum sab xis ntawm rab phom burner.

* Pitch Angle: cuam tshuam cov nplaim hluav taws sib cuam tshuam nrog pawg pawg ("licking the batch") thiab kev pab cuam ntawm cov yaj. Ib lub kaum sab xis uas qis dhau (nplaim qis dhau mus) tuaj yeem ua rau lub ntsej muag yaj lossis pawg pawg, ua rau cov khoom thauj uas cuam tshuam rau phab ntsa ntawm lub mis. Lub kaum sab xis uas siab dhau (nplaim taws dhau mus) ua rau muaj kev ua haujlwm thermal tsawg thiab cua sov ntau dhau ntawm cov yas.

* Yaw Lub kaum ntse ntse: cuam tshuam cov nplaim hluav taws faib thoob plaws lub qhov cub dav thiab qhov chaw kub kub.

2. Lub Hom Phiaj ntawm Kev Tswj Hluav Taws Xob:

* Tsim Qhov Chaw Kub Kub: Tsim qhov chaw kub siab tshaj plaws (kub qhov chaw) nyob rau sab nraub qaum ntawm lub tank melting (feem ntau tom qab doghouse). Qhov no yog qhov chaw tseem ceeb rau cov iav kom meej meej thiab homogenization, thiab ua raws li "lub cav" tswj cov iav yaj ntws (los ntawm qhov chaw kub kub ntawm lub charger thiab ua haujlwm kawg).

* Uniform Melt Surface Cua sov: Tsis txhob tso cua sov hauv cheeb tsam los yog qis qis, txo qis convection tsis sib xws thiab "qhov chaw tuag" tshwm sim los ntawm qhov kub thiab txias.

* Tiv Thaiv Cov Qauv Hluav Taws Xob: Tiv thaiv cov nplaim hluav taws kub hnyiab ntawm phab ntsa thiab lub mis, tsis txhob muaj cua sov hauv cheeb tsam uas ua rau kom nrawm dua qhov corrosion.

* Ua kom muaj cua sov zoo: Ua kom zoo tshaj plaws ntawm cov hluav taws xob hluav taws xob thiab hluav taws xob hloov hluav taws xob los ntawm cov nplaim hluav taws mus rau cov khoom siv thiab cov iav yaj.

* Ruaj khov Temperature Field: Txo qhov hloov pauv kom ruaj khov iav zoo.

III. Integrated Control ntawm Melting Temperature thiab Flame Regulation

1. Qhov kub thiab txias yog lub hom phiaj, nplaim taws yog qhov txhais tau tias: nplaim taws tswj hwm yog thawj txoj hauv kev los tswj qhov kub thiab txias hauv qhov cub, tshwj xeeb tshaj yog qhov chaw kub thiab txias.

2. Kev ntsuas kub thiab kev tawm tswv yim: Kev ntsuas kub tsis tu ncua yog ua los ntawm cov thermocouples, infrared pyrometers, thiab lwm yam khoom siv nyob rau ntawm qhov chaw tseem ceeb hauv qhov cub (batch charger, melting zone, hot spot, fining zone, forehearth). Cov kev ntsuas no ua lub hauv paus rau kev kho cov nplaim taws.

3. Tsis Siv Neeg Tswj Systems: Niaj hnub nimno loj-scale tank furnaces dav siv DCS/PLC systems. Cov tshuab no cia li tswj cov nplaim taws thiab qhov kub thiab txias los ntawm kev kho qhov tsis xws li roj ntws, combustion air flow, burner angle/dampers, raws li preset kub curves thiab real-time ntsuas.

4. Cov txheej txheem sib npaug: Nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug ntawm kev ua kom cov iav zoo (siab kub melting, zoo clarification thiab homogenization) thiab tiv thaiv lub cub tawg (tsis txhob kub dhau, nplaim taws) thaum txo kev siv hluav taws xob.
