CCEFIRE® DEHA Series High alumina refractory njerwa ndi mtundu wa ndale refractory zakuthupi ndi zotayidwa zopitirira 48%. Njerwa zapamwamba za alumina zimapangidwa kudzera kuwerengetsera ndi kuumba kuchokera ku bauxite ndi zida zina zokhala ndi aluminiyamu wambiri. Malinga ndi zomwe zili mu alumina mu njerwa yayikulu ya aluminiyamu, kukana kwake kwa moto, kukana kwa katundu, mphamvu zopondereza ndi zizindikiro zina zimasiyanasiyana.
Ubwino Wazinthu Wokhazikika
Kulamulira mwamphamvu kwa zipangizo
Sungani zonyansa, onetsetsani kuti kutentha kumachepa, ndikuwongolera kutentha
1. Kukhala ndi maziko olimba akulu, zida zaukatswiri zamigodi, ndi kusankha kokhwimitsa zinthu.
2. Zopangira zomwe zikubwera zimayesedwa poyamba, ndiyeno zopangira zoyenerera zimasungidwa m'malo osungiramo zinthu zosankhidwa kuti zitsimikizire chiyero chawo.
3. Zida za CCEFIRE High alumina njerwa zimakhala ndi zonyansa zochepa zomwe zimakhala ndi oxides zosakwana 1%, monga chitsulo ndi zitsulo za alkali. Chifukwa chake, njerwa za CCEFIRE High alumina zimakhala ndi kukana kwakukulu.
Kuwongolera njira zopangira
Chepetsani zomwe zili mumipira ya slag, onetsetsani kuti kutentha kumatsika, ndikuwongolera magwiridwe antchito amafuta
1. Dongosolo la batching lathunthu limatsimikizira kukhazikika kwa kapangidwe kazinthu zopangira komanso kulondola kwabwino mu chiŵerengero cha zinthu zopangira.
2. Pokhala ndi mizere yopangira makina apamwamba kwambiri padziko lonse lapansi ya ng'anjo zotentha kwambiri, ng'anjo zamoto, ndi ng'anjo zozungulira, njira zopangira kuchokera kuzinthu zopangira kupita kuzinthu zomalizidwa zimayendetsedwa ndi makompyuta, ndikuwonetsetsa kuti zinthu zili bwino.
3. ng'anjo zodzitchinjiriza, kuwongolera kutentha kokhazikika, kutsika kwa kutentha kwa CCEFIRE Njerwa zapamwamba za alumina, magwiridwe antchito abwino kwambiri otenthetsera kutentha, osakwana 0.5% pakusintha kwa mzere wokhazikika, mtundu wokhazikika, komanso moyo wautali wautumiki.
4. Maonekedwe osiyanasiyana a njerwa zapamwamba za alumina amatha kupangidwa molingana ndi mapangidwe. Ali ndi miyeso yolondola ndi cholakwika cha +1mm ndipo ndi yabwino kuti makasitomala ayike.
Kuwongolera khalidwe
Onetsetsani kachulukidwe kachulukidwe ndikuwongolera magwiridwe antchito amatenthedwe
1. Kutumiza kulikonse kumakhala ndi woyang'anira khalidwe lodzipatulira, ndipo lipoti loyesa limaperekedwa asananyamuke katundu kuchokera ku fakitale kuti atsimikizire kuti malonda a kunja kwa katundu aliyense wa CCEFIRE.
2. Kuwunika kwa gulu lachitatu (monga SGS, BV, etc.) kumavomerezedwa.
3. Kupanga kumayenderana ndi chitsimikizo cha ASTM Quality Management System.
4. Kupaka kunja kwa katoni iliyonse kumapangidwa ndi zigawo zisanu za mapepala a kraft, ndi ma CD akunja + pallet, oyenera kuyenda mtunda wautali.
Makhalidwe Odziwika
1. Kukana
The refractoriness wa CCEFIRE mkulu aluminiyanje njerwa ndi wapamwamba kuposa wa dongo refractory njerwa ndi theka-silica njerwa, kufika 1750 ~ 1790 ℃, amene ndi mtundu wapamwamba kalasi refractory zipangizo.
2. Katundu kufewetsa kutentha
Popeza zopangidwa ndi aluminiyamu mkulu Al2O3 mkulu, zosafunika zochepa, ndi magalasi ochepa fusible, katundu kufewetsa kutentha ndi wapamwamba kuposa wa njerwa dongo, koma chifukwa mullite makhiristo sapanga dongosolo maukonde, katundu kufewetsa kutentha akadali osati mkulu monga silika njerwa.
3. Slag kukana
Njerwa za CCEFIRE zokhala ndi aluminiyamu zambiri zimakhala ndi Al2O3 zambiri, pafupi ndi zinthu zosalowerera ndale, kotero zimatha kukana kukokoloka kwa asidi slag ndi slag zamchere. Chifukwa cha zomwe zili mu SiO2, kukana kwa alkaline slag ndikocheperako kusiyana ndi acid slag.
Njerwa zazitali za aluminiyamu zomwe zimakhala ndi kukhazikika kwamafuta ambiri, kukana kwambiri kuposa madigiri a 1770, kukana bwino kwa slag, komwe kumagwiritsidwa ntchito ngati ng'anjo yamagetsi yamagetsi, ng'anjo yamagetsi, ng'anjo yotentha, ladle, chitsulo chosungunuka, ng'anjo ya simenti, ng'anjo yamagalasi ndi ng'anjo ina yotentha. Amagwiritsidwa ntchito kwambiri pakupanga chitsulo, kupanga zitsulo, makampani opanga mankhwala, simenti ndi mafakitale ena.
