CCEFIRE® DEHA Series High alumina refractory njerwa ndi mtundu wa zinthu zosaloledwa zotsalira zomwe zili ndi zotayidwa zoposa 48%. Mkulu aluminiyamu refractory njerwa amapangidwa kudzera calcination ndi akamaumba ku bauxite ndi zipangizo zina zopangira ndi zili mkulu wa aluminiyamu. Malinga ndi zomwe zili ndi alumina mumitengo yayitali kwambiri ya alumina, kuyimitsa kwake moto, kutsitsimutsa katundu, mphamvu zowonongera komanso zizindikilo zina ndizosiyanasiyana.
Khola lazamalonda
Kulamulira mosamalitsa kwa zopangira
Sungani zodetsa, onetsetsani kuchepa kwamatenthedwe, ndikuwongolera kukana kutentha
1. Ali ndi maziko akulu a miyala, zida zamigodi zaluso, komanso kusankha zinthu zopitilira muyeso.
2. Zipangizo zomwe zikubwera zimayesedwa kaye, kenako zida zoyenerera zimasungidwa mnyumba yosungira kuti muwonetsetse kuti ndi yoyera.
3. Zipangizo za CCEFIRE Njerwa za alumina zapamwamba zimakhala ndi zosakwanira zochepa zosakwana 1% ya oxides, monga chitsulo ndi zitsulo za alkali. Chifukwa chake, njerwa za CCEFIRE High zimakhala ndi kukonzanso kwakukulu.
Kupanga njira zowongolera
Kuchepetsa zili slag mipira, kuonetsetsa otsika matenthedwe madutsidwe, ndi kusintha matenthedwe kutchinjiriza ntchito
1. Makina osinthira kwathunthu amatsimikizira kukhazikika kwa zopangira ndikulondola kwabwino pazowonjezera.
2. Ndi makina otsogola otsogola padziko lonse lapansi owotchera otchinga kwambiri, ng'anjo zotsekera, ndi ng'anjo zowotchera, njira zopangira kuchokera kuzinthu zopangira mpaka zotsirizidwa zimayang'aniridwa ndi makina apakompyuta, kuwonetsetsa kuti mankhwala ndi abwino.
3. Ng'anjo yamagetsi, kutentha kwamphamvu, kutsika kwamatenthedwe a CCEFIRE Njerwa zapamwamba za alumina, magwiridwe antchito abwino kwambiri, ochepera 0,5% pakusintha kwamuyaya, mtundu wokhazikika, komanso moyo wautali.
4. Mitundu yosiyanasiyana ya njerwa zapamwamba za alumina zimatha kupangidwa molingana ndi kapangidwe kake. Ali ndi kukula kwakukulu ndi cholakwika cha + 1mm ndipo ndiosavuta kuti makasitomala aziyika.
Kuwongolera kwamakhalidwe
Onetsetsani kuchuluka kwake ndikukwaniritsa magwiridwe antchito otentha
1. Katundu aliyense amakhala ndi woyang'anira wabwino wodzipereka, ndipo lipoti loyesa limaperekedwa isananyamuke zinthu kuchokera ku fakitala kuti zitsimikizire kuti kutumiza kwa CCEFIRE kulikonse.
2. Kuyendera gulu lachitatu (monga SGS, BV, ndi zina) kumavomerezedwa.
3. Kupanga kumatsata malinga ndi chitsimikizo cha kasamalidwe kabwino ka ASTM.
4. Kuyika kwakunja kwa katoni iliyonse kumapangidwa ndi zigawo zisanu za kraft pepala, ndi ma phukusi akunja + mphasa ,, oyenera mayendedwe ataliatali.
Makhalidwe Apadera
1. Refractoriness
Refractoriness of CCEFIRE high alumina bricks is more than that of dongo refractory bricks and semi-silika bricks, ukufika 1750 ~ 1790 ℃, womwe ndi mtundu wa zida zapamwamba zotsika.
2. Kutentha kwachangu
Popeza mankhwala okhala ndi alumina okwera amakhala ndi Al2O3 yambiri, zosowa zochepa, komanso magalasi ocheperako, kutentha kochepetsera katundu kumakhala kwakukulu kuposa njerwa zadongo, koma chifukwa makhiristo mullite samapanga maukonde, kutentha kwakanthawi kocheperako sikokwanira njerwa za silika.
3. Kukaniza kwa slag
Njerwa za CCEFIRE zamtundu wa alumina zimakhala ndi Al2O3 yambiri, pafupi ndi zinthu zosaloledwa, zomwe zimatha kukana kukokoloka kwa slag ya acid ndi slagine. Chifukwa cha zomwe zili mu SiO2, kukana kwa slagine slag ndikofooka kuposa acid slag.
Mkulu aluminiyamu njerwa yodziwika ndi mkulu matenthedwe bata, mkulu refractoriness pamwamba madigiri 1770, chabwino slag kukana, makamaka ntchito magetsi ng'anjo pamwamba, kutsinde ng'anjo, otentha kuphulika ng'anjo, ladle, chitsulo chosungunula, uvuni simenti, uvuni galasi ndi zina matenthedwe ng'anjo akalowa. Chimagwiritsidwa ntchito kupanga chitsulo, kupanga zitsulo, makampani mankhwala, simenti ndi mafakitale ena.
