E-iav (fiberglass tsis muaj alkali)Kev tsim khoom hauv cov cub tawg yog ib qho txheej txheem nyuaj, kub siab yaj. Qhov kub yaj yog qhov tseem ceeb tswj cov txheej txheem, cuam tshuam ncaj qha rau qhov zoo ntawm iav, kev ua haujlwm yaj, kev siv hluav taws xob, lub neej ntawm lub cub tawg, thiab kev ua haujlwm ntawm cov fiber kawg. Qhov kub no feem ntau yog ua tiav los ntawm kev kho cov yam ntxwv ntawm nplaim taws thiab kev txhawb nqa hluav taws xob.
I. Kub yaj ntawm E-Iav
1. Qhov Kub Yaj Ntau:
Feem ntau, qhov kub ntawm E-iav uas yaj tag, ua kom pom tseeb, thiab sib xyaw ua ke yuav tsum tau kub heev. Qhov kub ntawm thaj chaw yaj (qhov chaw kub) feem ntau yog li ntawm 1500 ° C txog 1600 ° C.
Qhov kub tshwj xeeb ntawm lub hom phiaj nyob ntawm:
* Cov Khoom Siv Ua Ib Pawg: Cov qauv tshwj xeeb (piv txwv li, muaj fluorine, cov ntsiab lus boron siab/qis, muaj titanium) cuam tshuam rau cov yam ntxwv yaj.
* Tsim Lub Qhov Cub: Hom qhov cub, qhov loj me, kev ua haujlwm ntawm kev rwb thaiv tsev, thiab kev teeb tsa lub qhov cub.
* Lub Hom Phiaj Tsim Khoom: Qhov nrawm yaj thiab qhov zoo ntawm iav xav tau.
* Cov Khoom Siv Refractory: Qhov corrosion ntawm cov khoom siv refractory ntawm qhov kub siab txwv qhov kub siab.
Qhov kub ntawm thaj chaw ua kom zoo feem ntau qis dua qhov kub ntawm qhov chaw kub (kwv yees li 20-50 ° C qis dua) kom yooj yim tshem tawm cov npuas thiab ua kom iav sib xyaw.
Qhov kub ntawm qhov kawg ua haujlwm (forehearth) qis dua (feem ntau yog 1200 ° C - 1350 ° C), coj cov iav yaj mus rau qhov viscosity thiab ruaj khov rau kev kos duab.
2. Qhov Tseem Ceeb ntawm Kev Tswj Kub:
* Kev Ua Haujlwm Zoo: Qhov kub siab txaus yog qhov tseem ceeb rau kev ua kom tiav cov tshuaj tiv thaiv ntawm cov khoom siv (xuab zeb quartz, pyrophyllite, boric acid/colemanite, limestone, thiab lwm yam), yaj tag nrho cov xuab zeb, thiab tso pa tawm tag nrho. Qhov kub tsis txaus tuaj yeem ua rau cov khoom seem "raw" (cov khoom quartz tsis yaj), pob zeb, thiab cov npuas ntau ntxiv.
* Qhov Zoo ntawm Cov Iav: Qhov kub siab ua rau cov iav yaj kom du thiab sib npaug, txo cov qhov tsis zoo xws li cov hlua, cov npuas, thiab cov pob zeb. Cov qhov tsis zoo no cuam tshuam rau lub zog ntawm cov fiber, qhov nrawm ntawm kev tawg, thiab kev sib txuas.
* Viscosity: Kub ncaj qha cuam tshuam rau qhov viscosity ntawm cov iav yaj. Kev kos duab fiber xav kom cov iav yaj nyob hauv qhov ntau yam viscosity tshwj xeeb.
* Kev Xeb ntawm Cov Khoom Siv Refractory: Qhov kub siab dhau heev ua rau kev xeb ntawm cov khoom siv refractory hauv lub cub tawg (tshwj xeeb tshaj yog cov cib AZS uas tau siv hluav taws xob), ua rau lub cub tawg lub neej luv dua thiab ua rau muaj cov pob zeb refractory.
* Kev Siv Hluav Taws Xob: Kev tswj qhov kub thiab txias siab yog qhov tseem ceeb ntawm kev siv hluav taws xob hauv cov cub tawg (feem ntau suav txog ntau dua 60% ntawm tag nrho cov zog siv). Kev tswj qhov kub kom raug kom tsis txhob muaj qhov kub ntau dhau yog qhov tseem ceeb rau kev txuag hluav taws xob.
II. Kev Tswj Hluav Taws
Kev tswj nplaim taws yog ib txoj hauv kev tseem ceeb ntawm kev tswj qhov kub thiab txias ntawm lub cub tawg, ua kom lub cub tawg yaj tau zoo, thiab tiv thaiv cov qauv ntawm lub cub tawg (tshwj xeeb tshaj yog lub hau). Nws lub hom phiaj tseem ceeb yog los tsim kom muaj qhov kub thiab txias zoo tshaj plaws.
1. Cov Kev Cai Tswjfwm Tseem Ceeb:
* Qhov Sib Piv ntawm Roj thiab Huab Cua (Stoichiometric Ratio) / Qhov Sib Piv ntawm Oxygen thiab Roj (rau cov tshuab oxy-fuel):
* Lub Hom Phiaj: Ua kom tiav qhov kev kub hnyiab tag nrho. Kev kub hnyiab tsis tag nrho yuav ua rau roj nkim, txo qhov kub ntawm nplaim taws, tsim cov pa luam yeeb dub (sot) uas ua rau cov iav yaj tsis huv, thiab txhaws cov khoom siv rov ua dua tshiab / cov khoom sib pauv cua sov. Cov pa ntau dhau coj cov cua sov mus, txo qhov ua haujlwm thermal, thiab tuaj yeem ua rau cov hlau oxidation xeb ntxiv.
* Kev Kho Kom Zoo: Tswj qhov sib piv ntawm huab cua thiab roj raws li kev tshuaj xyuas roj flue (O₂, CO cov ntsiab lus).E-iavcov cub tawg feem ntau tswj cov pa roj flue O₂ ntawm kwv yees li 1-3% (kev sib xyaw ua ke zoo me ntsis).
* Kev Cuam Tshuam Rau Huab Cua: Qhov sib piv ntawm huab cua thiab roj kuj cuam tshuam rau huab cua ntawm lub cub tawg (oxidizing lossis txo qis), uas muaj cov teebmeem me me rau tus cwj pwm ntawm qee yam khoom siv (xws li hlau) thiab xim iav. Txawm li cas los xij, rau E-iav (xav tau qhov tsis muaj xim pob tshab), qhov kev cuam tshuam no yog me me xwb.
* Qhov Ntev thiab Duab ntawm nplaim taws:
* Lub Hom Phiaj: Tsim ib lub nplaim taws uas npog qhov chaw yaj, muaj qee qhov rigidity, thiab muaj kev sib kis tau zoo.
* Hluav Taws Ntev vs. Hluav Taws Luv:
* Hluav Taws Ntev: Npog thaj chaw loj, qhov kub faib sib npaug zos, thiab ua rau muaj kev poob siab tsawg dua rau lub kaus mom. Txawm li cas los xij, qhov kub siab tshaj plaws hauv zos yuav tsis siab txaus, thiab kev nkag mus rau hauv thaj chaw "drilling" tej zaum yuav tsis txaus.
* Hluav Taws Luv: Muaj zog rigidity, kub hauv zos siab, nkag mus rau hauv cov txheej batch, ua rau yaj sai ntawm "cov khoom siv raw." Txawm li cas los xij, kev npog tsis sib npaug, yooj yim ua rau kub dhau (qhov kub tshaj plaws), thiab muaj kev kub ntxhov loj rau lub kaus mom thiab phab ntsa ntawm lub mis.
* Kev Kho Kom Haum: Ua tiav los ntawm kev kho lub kaum sab xis ntawm rab phom hlawv, qhov ceev ntawm roj/cua tawm (qhov sib piv ntawm lub zog), thiab qhov sib hloov ntawm lub zog. Cov cub tawg niaj hnub no feem ntau siv cov cub tawg uas kho tau ntau theem.
* Kev Taw Qhia Hluav Taws (Lub Kaum):
* Lub Hom Phiaj: Hloov cua sov mus rau qhov chaw ua haujlwm thiab qhov chaw yaj iav kom zoo, zam kom tsis txhob muaj nplaim taws ncaj qha rau ntawm lub kaus mom lossis phab ntsa ntawm lub hauv siab.
* Kev Kho Kom Zoo: Kho lub suab (ntsug) thiab yaw (kab rov tav) ntawm rab phom hlawv.
* Lub kaum sab xis ntawm lub nplaim taws: Cuam tshuam rau qhov nplaim taws sib cuam tshuam nrog pawg khoom ("licking the batch") thiab kev npog ntawm qhov chaw yaj. Lub kaum sab xis uas qis dhau (hluav taws nqes mus rau hauv qab) yuav ua rau qhov chaw yaj lossis pawg khoom puas tsuaj, ua rau muaj kev thauj mus los uas ua rau lub phab ntsa ntawm lub hauv siab xeb. Lub kaum sab xis uas siab dhau (hluav taws nce mus rau saum toj) ua rau muaj kev ua haujlwm thermal qis thiab ua rau lub hau kub dhau.
* Yaw Angle: Cuam tshuam rau kev faib hluav taws thoob plaws qhov dav ntawm lub cub tawg thiab qhov chaw kub.
2. Lub Hom Phiaj ntawm Kev Tswj Hluav Taws:
* Tsim Ib Qho Chaw Kub Rational: Tsim thaj chaw kub tshaj plaws (qhov chaw kub) nyob rau sab nraub qaum ntawm lub tank yaj (feem ntau tom qab lub tsev dev). Qhov no yog thaj chaw tseem ceeb rau kev ua kom iav ntshiab thiab homogenization, thiab ua haujlwm ua "cav" tswj cov dej iav yaj (los ntawm qhov chaw kub mus rau lub batch charger thiab qhov kawg ua haujlwm).
* Kev Ua Kub Sib Npaug Ntawm Qhov Chaw Yaj: Tsis txhob ua kom sov dhau lossis txias dhau, txo qhov sib xyaw tsis sib xws thiab "cheeb tsam tuag" uas tshwm sim los ntawm qhov kub thiab txias.
* Tiv Thaiv Cov Qauv Rauv: Tiv thaiv kom tsis txhob muaj nplaim taws rau ntawm lub kaus mom thiab phab ntsa ntawm lub hauv siab, zam kev kub hnyiab uas ua rau muaj kev xeb sai.
* Kev Hloov Kub Zoo: Ua kom muaj kev ua haujlwm zoo tshaj plaws ntawm kev hloov cua sov thiab cua sov los ntawm nplaim taws mus rau qhov chaw thiab iav yaj.
* Qhov Kub Ruaj Khoov: Txo qhov kev hloov pauv kom ntseeg tau tias cov iav zoo ruaj khov.
III. Kev Tswj Xyuas Kub Thiab Kev Tswj Hluav Taws Kub Ua Ke
1. Kub yog Lub Hom Phiaj, Nplaim yog Qhov Txhais Tau: Kev tswj nplaim yog txoj hauv kev tseem ceeb rau kev tswj qhov kub thiab txias hauv lub cub tawg, tshwj xeeb tshaj yog qhov chaw kub thiab qhov kub.
2. Kev Ntsuas Kub thiab Kev Tawm Tswv Yim: Kev saib xyuas kub tas mus li yog ua los ntawm kev siv cov thermocouples, infrared pyrometers, thiab lwm yam cuab yeej uas muab tso rau ntawm qhov chaw tseem ceeb hauv lub cub tawg (batch charger, melting zone, hot spot, fining zone, forehearth). Cov kev ntsuas no ua lub hauv paus rau kev hloov kho nplaim taws.
3. Cov Txheej Txheem Tswj Xyuas Tsis Siv Neeg: Cov cub tawg loj niaj hnub no siv cov txheej txheem DCS/PLC. Cov txheej txheem no tswj hwm nplaim taws thiab kub los ntawm kev kho cov yam ntxwv xws li roj ntws, cua ntws, lub kaum sab xis / dampers ntawm lub cub tawg, raws li cov kab ntsuas kub ua ntej thiab kev ntsuas lub sijhawm tiag tiag.
4. Kev Sib Npaug ntawm Cov Txheej Txheem: Nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug zoo tshaj plaws ntawm kev ua kom cov iav zoo (yaj thaum kub heev, ua kom pom tseeb zoo thiab sib npaug) thiab tiv thaiv lub cub tawg (tsis txhob kub dhau, nplaim taws sib tsoo) thaum txo kev siv hluav taws xob.
