Mawu Oyamba
Njerwa za buluu za Alumina / Alumina zimapangidwa ndi mpira wosanjikiza wa alumina monga chopangira chachikulu, ufa wa corundum ultrafine monga chowonjezera, zinthu zakuthupi monga binder, pambuyo popanga ndi kuyanika, ndipo pamapeto pake zidawotchedwa mu uvuni wa 1750 ℃ wotentha kwambiri.Ndi m'gulu la njerwa zowala za corundum insulation, zinthuzi zimakhala ndi matenthedwe otsika a njerwa zotchinjiriza, komanso mphamvu yopondereza, Ndi njerwa yopepuka yotentha yomwe imatha kugwiritsidwa ntchito nthawi zonse pa 1700 ℃.Njerwa za Alumina zopanda mpira / Alumina kuwira njerwa ali ndi kutentha kwambiri kukana ndi kutentha kutchinjiriza ntchito, angagwiritsidwe ntchito mwachindunji ngati akalowa ntchito ya ng'anjo mkulu kutentha, kuchepetsa kulemera kwa ng'anjo thupi, kukonzanso dongosolo, kupulumutsa zipangizo, kupulumutsa mphamvu, adzakhala kupeza zotsatira zoonekeratu.
Njira
Kupanga kwa alumina dzenje mpira ndi pafupifupi motere: Choyamba, zopangira za aluminiyani anawonjezera mu kutaya mtundu arc ng'anjo kusungunuka mu madzi, ndiyeno ng'anjo anatayidwa pa ngodya inayake, kuti madzi osungunuka. amatuluka mu thanki kuthira pa liwiro linalake, ndipo madzi amayenda kudzera lathyathyathya nozzle 60 ° ~ 90 ndi kuthamanga kwa 0.6 ~ 0.8mpa mkulu liwiro airflow adzawombeza madzi otaya, ndiye aluminiyamu dzenje mpira.Mipira yopanda kanthu ya aluminiyamu nthawi zambiri imagawidwa m'miyeso isanu pambuyo poyang'ana ndipo mipira yosweka imachotsedwa ndi kupatukana kwamadzi.
Ubwino
1. Kutentha kwakukulu: Kutentha kwakukulu kofewa pansi pa katundu.Kuwotchanso mawaya kusintha mlingo ndi kochepa, ntchito yaitali.
2. Konzani dongosolo, kuchepetsa kulemera kwa ng'anjo: Tsopano ng'anjo yowotchera pogwiritsa ntchito zipangizo zosagwira kutentha kwambiri ndi njerwa zolemera, kuchuluka kwa 2.3-3.0g/cm, ndi njerwa za aluminium hollow mpira 1.3-1.5g /cm, wofanana kiyubiki mita voliyumu, ntchito alumina dzenje mpira njerwa akhoza kuchepetsa 1.1-1.9 matani kulemera.
3. Sungani zipangizo: Kukwaniritsa kutentha ntchito yomweyo, monga ntchito katundu wolemera njerwa corundum mtengo ndi aluminiyamu dzenje mpira njerwa mtengo ndi ofanana, komanso amafunika ndithu kutchinjiriza wosanjikiza zakuthupi refractory.Ngati kugwiritsa ntchito njerwa za alumina dzenje mpira, pa kiyubiki mita zitha kupulumutsa matani 1.1-1.9 a njerwa zolemera za corundum, zochulukirapo zitha kupulumutsa 80% ya zida zotchinjiriza moto.
4. Kupulumutsa mphamvu: Alumina dzenje mpira ali ndi makhalidwe zodziwikiratu matenthedwe kutchinjiriza, otsika matenthedwe madutsidwe, akhoza kuimba zabwino matenthedwe kutchinjiriza zotsatira, kuchepetsa kutentha umatulutsa, kusintha matenthedwe dzuwa, kuti apulumutse mphamvu.Mphamvu yopulumutsa mphamvu imatha kufika kuposa 30%.
