China kuwala kulemera mkulu zotayidwa matenthedwe kutchinjiriza njerwa fakitale ndi opanga | Rongsheng

Kufotokozera Kwachidule:

Njerwa yapamwamba ya aluminiyamu ndi mtundu wa refractory, chigawo chachikulu chomwe ndi Al2O3. Ngati zomwe zili mu Al2O3 ndizoposa 90%, zimatchedwa njerwa ya corundum. Chifukwa cha zinthu zosiyanasiyana, miyezo ya mayiko osiyanasiyana sikugwirizana kwathunthu. Mwachitsanzo, m'mayiko a ku Ulaya, malire otsika a Al2O3 opangidwa ndi alumina refractories apamwamba ndi 42%. Ku China, okhutira Al2O3 mu mkulu aluminiyanje njerwa zambiri anawagawa m'makalasi atatu: kalasi I - Al2O3 okhutira> 75%; kalasi II - zomwe zili mu Al2O3 ndi 60-75%; kalasi III - Al2O3 zili 48-60%.

Ntchito:

Njerwa zapamwamba za aluminiyamu zimagwiritsidwa ntchito kwambiri pomanga ng'anjo zamkati zamafakitale, monga ng'anjo zophulika, ng'anjo zotentha zotentha, ng'anjo yamagetsi yamagetsi, reverberator, ng'anjo ya simenti yozungulira ndi zina zotero. Kupatula apo, njerwa zazikulu za alumina zimagwiritsidwanso ntchito kwambiri ngati njerwa zosinthira, choyimitsa choponyera mosalekeza, njerwa za nozzle, etc.

Zam'mbuyo: Njerwa za JM23 zotentha kwambiri za mullite zotsekereza njerwa

Ena: Njerwa Yapamwamba ya Alumina Bubble Refractory
