Kupanga ndi Kumanga kwa Kupitiriza Kumangirira Kutentha Kwambiri Kumangirira Annealing Furnace Lining kwa Strip Steel
Mwachidule:
Njira yopangira galvanizing yotentha imagawidwa m'magulu awiri: kukopera pamzere ndi kunja kwa mzere kutengera njira zosiyanasiyana zochizira. Mng'anjo yopititsira patsogolo yotentha yopitilira zitsulo za strip ndi chida choyatsira chomwe chimatenthetsa mbale zoyambira zoviyitsa zotenthetsera panthawi yakukolezera. Malinga ndi njira zosiyanasiyana kupanga, Mzere zitsulo mosalekeza otentha-kuviika galvanizing ng'anjo annealing akhoza kugawidwa m'magulu awiri: ofukula ndi yopingasa. Ng'anjo yopingasa kwenikweni imakhala yofanana ndi ng'anjo yowongoka mosalekeza, yomwe ili ndi magawo atatu: ng'anjo yoyaka moto, ng'anjo yochepetsera, ndi gawo lozizirira. Ng'anjo yowongoka imatchedwanso ng'anjo ya nsanja, yomwe imapangidwa ndi gawo lotenthetsera, gawo lonyowa, ndi gawo lozizira.
Lining dongosolo la Mzere zitsulo mosalekeza annealing ng'anjo
ng'anjo zopangira nsanja
(1) Gawo lotenthetsera (ng'anjo yotenthetsera) limagwiritsa ntchito mpweya wamafuta amafuta ngati mafuta. Zowotcha gasi zimakonzedwa molingana ndi kutalika kwa khoma la ng'anjo. Chitsulo chachitsulo chimatenthedwa molowera komwe kumachokera ku gasi wang'anjo komwe kumapereka mpweya wofooka wa okosijeni. Kutentha gawo (preheating ng'anjo) ndi kapangidwe kavalo, ndi pamwamba ake ndi mkulu kutentha zone kumene nozzles burner anakonza ndi kutentha kwambiri ndi kuthamanga kwa mpweya scouring, kotero ng'anjo khoma akalowa utenga opepuka refractory zipangizo, monga CCEFIRE mkulu aluminium kuwala njerwa, kashiamu kutchinjiriza njerwa, ndi matenthedwe matabwa silika. Kutentha gawo la (preheating ng'anjo) otsika kutentha zone (kuvula zitsulo kulowa zone) ali ndi kutentha otsika ndi otsika otaya mpweya scouring liwiro, kotero CCEWOOL ceramic CHIKWANGWANI zigawo zambiri ntchito ngati zipangizo akalowa khoma.
Miyeso ya khoma la gawo lililonse ndi motere:
A. Pamwamba pa gawo Kutentha (preheating ng'anjo).
Njerwa za CCEFIRE za aluminiyamu zopepuka zopepuka zimasankhidwa ngati chinsalu chapamwamba cha ng'anjo.
B. Gawo la Kutenthetsera (ng'anjo yotenthetsera) yotentha kwambiri (zoni yowotcha)
Kutentha kwapamwamba kwa zone nthawi zonse kumakhala ndi zigawo zotsatirazi:
Njerwa za CCEFIRE High Aluminiyamu Zopepuka (zotentha zapakhoma)
Njerwa zotsekera za CCEFIRE
CCEWOOL kashiamu silicate matabwa (ozizira pamwamba pa khoma akalowa)
Malo otentha otsika amagwiritsa ntchito ma modules a CCEWOOL ceramic fiber (voliyumu ya 200Kg/m3) yokhala ndi zirconium pakupanga.
(2) Mugawo lonyowa (ng'anjo yochepetsera), chubu chowunikira gasi chimagwiritsidwa ntchito ngati gwero la kutentha kwa ng'anjo yochepetsera mizere. Machubu owala a gasi amakonzedwa motsatira kutalika kwa ng'anjo. Mzerewu umayenda ndikutenthedwa pakati pa mizere iwiri ya machubu owala. Ng'anjoyi ikuwonetsa kuchepetsa mpweya wa ng'anjo. Pa nthawi yomweyi, ntchito yokakamiza yabwino imasungidwa nthawi zonse. Chifukwa kukana kutentha ndi kutchinjiriza matenthedwe a CCEWOOL ceramic CHIKWANGWANI kwambiri yafupika pansi pa kukanikiza zabwino ndi kuchepetsa mikhalidwe mlengalenga, m'pofunika kuonetsetsa wabwino kukana moto ndi kutentha kutchinjiriza zotsatira za akalowa ng'anjo ndi kuchepetsa ng'anjo kulemera. Komanso, ng'anjo ya ng'anjo iyenera kuyendetsedwa mosamalitsa kuti mupewe kutsika kwa slag kuwonetsetsa kuti pamwamba pa mbale yoyambirira yamalata ndi yosalala komanso yoyera. Poganizira kutentha pazipita gawo kuchepetsa si upambana 950 ℃, ndi akuwukha gawo la (kuchepetsa ng'anjo) ng'anjo makoma kutenga mkulu-kutentha kutchinjiriza wosanjikiza dongosolo CCEWOOL ceramic CHIKWANGWANI mabulangete kapena thonje sandwiched pakati pa zigawo ziwiri za zitsulo zosagwira kutentha, kutanthauza CCEWOOL ceramic CHIKWANGWANI bulangete kapena awiri thonje wosanjikiza mbale zitsulo zopakapaka. Ceramic fiber interlayer imapangidwa ndi zinthu zotsatirazi za ceramic fiber.
Chosanjikiza chachitsulo chosagwira kutentha pamtunda wotentha chimagwiritsa ntchito zofunda za CCEWOOL zirconium fiber.
Wosanjikiza wapakati amagwiritsa ntchito zofunda za CCEWOOL zoyera kwambiri za ceramic fiber.
wosanjikiza pafupi ndi ozizira pamwamba zitsulo mbale amagwiritsa CCEWOOL wamba ceramic CHIKWANGWANI thonje.
Pamwamba ndi makoma a gawo lonyowa (ng'anjo yochepetsera) amatengera mawonekedwe omwe ali pamwambapa. Ng'anjoyo imasunga mpweya wocheperako wa ng'anjo wokhala ndi 75% H2 ndi 25% N2 kuti azindikire kulumikizidwanso kwachitsulo chamzere ndikuchepetsa kwachitsulo okusayidi pamwamba pazitsulo.
(3) Chigawo choziziritsa: Machubu oziziritsidwa ndi mpweya amaziziritsa chingwe kuchokera ku ng'anjo yamoto (700-800 ° C) ya gawo lonyowa (ng'anjo yochepetsera) mpaka kutentha kwa zinki pot galvanizing (460-520 ° C), ndipo gawo loziziritsa limasunga mpweya wochepetsera ng'anjo.
Mzere wa gawo loziziritsa umakhala ndi matailosi a CCEWOOL zofunda zoyera kwambiri za ceramic fiber.
(4) Kulumikiza zigawo za gawo lotenthetsera (ng'anjo yowotchera), gawo lonyowa (ng'anjo yochepetsera), ndi gawo lozizira, ndi zina.
Zomwe zili pamwambazi zikuwonetsa kuti njira yowotchera zitsulo zoziziritsa kuzizira zisanayambe kuviika moto ziyenera kudutsa njira, monga kutenthetsa-kuzizira-kuzizira, ndipo ndondomeko iliyonse imachitika m'mapangidwe osiyanasiyana ndi zipinda zodziyimira pawokha, zomwe zimatchedwa ng'anjo yoyaka moto, ng'anjo yochepetsera, ndi chipinda chozizira motsatana, ndipo zimapanga chingwe cholumikizira mosalekeza. ng'anjo). Panthawi yopangira annealing, chitsulo chachitsulo chimadutsa mosalekeza m'zipinda zodziyimira pawokha zomwe tazitchula pamwambapa pa liwiro lalikulu la 240m / min. Pofuna kupewa makutidwe ndi okosijeni wa zitsulo zopangira zitsulo, zigawo zogwirizanitsa zimazindikira kugwirizana pakati pa zipinda zodziimira, zomwe sizimangolepheretsa zitsulo zachitsulo kukhala oxidized pamagulu a zipinda zodziyimira pawokha, komanso zimatsimikizira kusindikiza ndi kusunga kutentha.
Zigawo zolumikizirana pakati pa chipinda chilichonse chodziyimira pawokha zimagwiritsa ntchito zida za ceramic monga zida zokutira. Zida ndi mamangidwe ake ndi awa:
Chingwecho chimatengera zinthu za CCEWOOL ceramic fiber komanso mawonekedwe athunthu a fiber fiber modules. Ndiko kuti, kutentha pamwamba pa akalowa ndi CCEWOOL zirconium okhala ndi ceramic fiber modules + matailosi CCEWOOL wamba ceramic fiber mabulangete (ozizira pamwamba).
Chopingasa kapangidwe ng'anjo
Malingana ndi zofunikira zosiyanasiyana zamakono za gawo lililonse la ng'anjo yopingasa, ng'anjoyo ikhoza kugawidwa m'magawo asanu: gawo la preheating (PH gawo), gawo lotentha lopanda oxidizing (NOF gawo), gawo lonyowa (gawo lochepetsera kutentha kwa chubu; gawo la RTF), gawo lozizira mofulumira (gawo la JFC), ndi gawo loyendetsa (TDS gawo). Zomangamanga zenizeni ndi izi:
(1) Gawo la preheating:
Pamwamba pa ng'anjo ndi makoma a ng'anjo amatengera ng'anjo yophatikizika yokhala ndi ma CCEWOOL ceramic fiber modules ndi mabulangete a ceramic fiber. Chophimba chotsika chotsika chimagwiritsa ntchito mabulangete a CCEWOOL 1260 ophimbidwa mpaka 25mm, pomwe malo otentha amagwiritsa ntchito midadada ya CCEWOOL ya zirconium yokhala ndi fiber. Kuyika pazigawo zotentha kwambiri kumatenga bulangeti la CCEWOOL 1260, ndipo malo otentha amagwiritsa ntchito ma module a ceramic fiber.
Pansi pa ng'anjoyo amatengera kuyika kophatikizana kwa njerwa zadongo zopepuka ndi ma module a ceramic fiber; mbali zotsika kutentha zimatengera kapangidwe ka njerwa zadongo zopepuka komanso ma module a ceramic okhala ndi zirconium, pomwe mbali zotentha kwambiri zimatengera mawonekedwe a njerwa zadongo zopepuka ndi ma module a ceramic fiber.
(2) Palibe gawo la kutentha kwa okosijeni:
Pamwamba pa ng'anjoyo amatengera kapangidwe kake ka ceramic fiber modules ndi mabulangete a ceramic fiber, ndipo kumbuyo kumatengera mabulangete 1260 a ceramic fiber.
Mbali zofala za makoma a ng'anjo: ng'anjo yopangidwa ndi ng'anjo yopangidwa ndi CCEFIRE yopepuka njerwa ya aluminiyamu yopepuka + CCEFIRE njerwa zotentha zotentha zotentha (kuchuluka kwa voliyumu 0.8kg/m3) + CCEWOOL 1260 mabulangete a ceramic fiber + CCEWOOL calcium silicate board.
Zowotcha pamakoma a ng'anjo zimatengera kapangidwe ka ng'anjo ya ng'anjo ya CCEFIRE yopepuka yopepuka ya alumina njerwa + CCEFIRE njerwa zopepuka zotenthetsera matenthedwe (kuchuluka kwa voliyumu 0.8kg/m3) + 1260 CCEWOOL mabulangete a ceramic fiber + CCEWOOL calcium silicate board.
(3) Chigawo chonyowa:
Pamwamba pa ng'anjoyo pamakhala ng'anjo yopangidwa ndi mabulangete a CCEWOOL ceramic fiberboard.
