Machubu owala a gasi amakonzedwa motsatira kutalika kwa ng'anjo. Chingwecho chimayenda ndikutenthedwa pakati pa mizere iwiri ya machubu owala a gasi. Ng'anjoyo imapereka mpweya wocheperako wa ng'anjo. Nthawi yomweyo, ntchito yabwino ya kupanikizika imasungidwa nthawi zonse. Chifukwa kukana kutentha ndi kutentha kwa ulusi wa CCEWOOL ceramic kumachepetsedwa kwambiri chifukwa cha kupanikizika kwabwino komanso mlengalenga wocheperako, ndikofunikira kuonetsetsa kuti kukana bwino moto ndi zotsatira zoteteza kutentha kwa ng'anjoyo ndikuchepetsa kulemera kwa ng'anjoyo. Komanso, ng'anjoyo iyenera kulamulidwa mosamala kuti isagwe kuti iwonetsetse kuti pamwamba pa mbale yoyambirira ya galvanized ndi yosalala komanso yoyera. Poganizira kutentha kwakukulu kwa gawo lochepetsera sikupitirira 950 ℃, makoma a ng'anjo ya gawo lonyowetsa (ng'anjo yochepetsera) amakhala ndi kapangidwe ka kutenthetsa kutentha kwambiri ka mabulangeti a CCEWOOL ceramic fiber kapena thonje lopangidwa pakati pa zigawo ziwiri zachitsulo chosagwira kutentha, zomwe zikutanthauza kuti bulangeti la ulusi wa CCEWOOL ceramic kapena wosanjikiza wa thonje limapangidwa pakati pa mbale ziwiri zachitsulo. Chipinda cha ceramic fiber chimapangidwa ndi zinthu zotsatirazi za ceramic fiber.
Chitsulo chosagwira kutentha pamwamba pa kutentha chimagwiritsa ntchito mabulangeti a CCEWOOL zirconium fiber.
Gawo lapakati limagwiritsa ntchito mabulangeti a CCEWOOL okhala ndi ulusi wa ceramic woyeretsedwa kwambiri.
Chigawo chomwe chili pafupi ndi mbale yachitsulo yozizira pamwamba pake chimagwiritsa ntchito thonje la CCEWOOL wamba wa ulusi wa ceramic.
Pamwamba ndi makoma a gawo lonyowetsa (ng'anjo yochepetsera) zimakhala ndi kapangidwe kofanana ndi komwe kali pamwambapa. Ng'anjoyo imasunga mpweya wochepetsera ng'anjo wokhala ndi 75% H2 ndi 25% N2 kuti igwirenso ntchito ngati chitsulo chopopera komanso kuchepetsa chitsulo chopopera pamwamba pa chitsulo chopopera.
(3) Gawo Loziziritsira: Machubu owala oziziritsidwa ndi mpweya amaziziritsa mzerewo kuyambira kutentha kwa ng'anjo (700-800°C) ya gawo lonyowetsa (ng'anjo yochepetsera) mpaka kutentha kwa zinc pot galvanizing (460-520°C), ndipo gawo loziziritsira limasunga mpweya wochepetsera ng'anjo.
Chipinda choziziritsira chimafanana ndi kapangidwe ka matailosi ka mabulangeti a CCEWOOL okhala ndi ulusi wa ceramic woyeretsedwa kwambiri.
(4) Kulumikiza magawo a gawo lotenthetsera (ng'anjo yotenthetsera), gawo lonyowetsa (ng'anjo yochepetsera), ndi gawo loziziritsira, ndi zina zotero.
Zomwe zili pamwambapa zikusonyeza kuti njira yothira zitsulo zozungulira zozizira isanayambe kuviika mu galvanizing iyenera kudutsa munjira zosiyanasiyana, monga kutenthetsa-kunyowetsa-kuzizira, ndipo njira iliyonse imachitika m'mapangidwe osiyanasiyana ndi zipinda zodziyimira pawokha za ng'anjo, zomwe zimatchedwa ng'anjo yotenthetsera, ng'anjo yochepetsera, ndi chipinda choziziritsira motsatana, ndipo amapanga gawo lopitilira la strip annealing (kapena ng'anjo yothira). Panthawi yothira, chitsulo chothira chimadutsa mosalekeza m'zipinda zodziyimira pawokha za ng'anjo zomwe zatchulidwa pamwambapa pa liwiro lalikulu la 240m/min. Pofuna kupewa kukhuthala kwa chitsulo chothira, magawo olumikizira amazindikira kulumikizana pakati pa zipinda zodziyimira pawokha, zomwe sizimangoletsa chitsulo chothira kuti chisakhuthale pamalo olumikizira zipinda zodziyimira pawokha za ng'anjo, komanso zimateteza kutsekedwa ndi kusungidwa kwa kutentha.
Zigawo zolumikizira pakati pa chipinda chilichonse chodziyimira pawokha zimagwiritsa ntchito zipangizo za ulusi wa ceramic ngati zipangizo zolumikizira. Zipangizo ndi kapangidwe kake ndi izi:
Chipindacho chimagwiritsa ntchito zinthu za CCEWOOL ceramic fiber ndi kapangidwe ka ulusi wonse wa ma module a ceramic fiber okhala ndi matailosi. Izi zikutanthauza kuti, pamwamba pa chipindacho pali ma module a CCEWOOL zirconium okhala ndi ulusi wa ceramic + mabulangeti a CCEWOOL wamba a ceramic fiber (pamwamba pozizira).
