Zida za alumina zitha kugwiritsidwa ntchito pazida zotentha kwambiri komanso zogwiritsidwa ntchito kwambiri mumakampani opanga magetsi.

Mu makampani opanga magetsi otentha, zida nthawi zambiri zimawonongeka chifukwa cha kutentha kwambiri komanso kuwonongeka kwambiri, zomwe zimakhudza chitetezo cha makina onse. Kuti tithetse vutoli, ndikofunikira kupeza zipangizo zomwe zimatha kupirira kutentha kwambiri komanso kukana kuwonongeka. Zipangizo za alumina ceramic ndizoyenera kwambiri.

Alumina ceramic ndi mtundu wa alumina (Al2O3) ngati zinthu zopangira ceramic, pambuyo pokanikiza mouma, kenako kudzera mu kutentha kopitilira madigiri 1,700. Ma ceramic a alumina ali ndi mawonekedwe a conductivity yabwino, mphamvu yamakina, kukana kutentha kwambiri komanso kukana dzimbiri. Poyesedwa ndi Shanghai Institute of Silicate of the Chinese Academy of Sciences, kuuma kwake kwa Rockwell ndi HRA80-90, kuuma kwake ndi kwachiwiri pambuyo pa diamondi, kuposa kukana kwa chitsulo chosagwira ntchito komanso chitsulo chosapanga dzimbiri. Kukana kwa chitsulo cha manganese ndi kuwirikiza 266 kuposa chitsulo cha chromium chochuluka. Malinga ndi kafukufuku wathu wotsatira makasitomala kwa zaka zoposa khumi, pansi pa mikhalidwe yomweyi yogwirira ntchito, nthawi yogwirira ntchito ya zida imatha kukulitsidwa osachepera nthawi khumi.

Zida za alumina zitha kugwiritsidwa ntchito m'zida zotentha kwambiri komanso zogwiritsidwa ntchito kwambiri mumakampani opanga magetsi, monga mafani, ma rotor a pampu, zipolopolo, mapaipi, mipando, mphete zotsekera, ndi zina zotero. Zida izi zimafunika kupirira kutentha kwambiri, kuthamanga kwambiri komanso zinthu zowononga, kotero zimafunika kugwiritsa ntchito zipangizo zabwino zopewera kuwonongeka popanga.

Mu makampani opanga magetsi, mphero ya malasha ndiye chida chofunikira kwambiri, ndipo kugwiritsa ntchitozoumbaumba zosatha kuthaZingathandize kwambiri kukonza moyo wa ntchito ya mphero ya malasha, kenako ndikuwonetsetsa kuti makina onse a boiler akuyenda bwino. Izi sizingochepetsa nthawi yomwe zida sizikugwira ntchito, komanso zingathandize kuti makina a boiler azigwira ntchito bwino, komanso zimachepetsa mtengo wokonza zida, zomwe zikugwirizana ndi kufunafuna phindu lazachuma mumakampani opanga magetsi.

Tiyenera kudziwa kuti pogwiritsira ntchito zinthu zenizeni, zofunikira, zomwe zili mkati, momwe zimagwiritsidwira ntchito komanso momwe zimagwiritsidwira ntchito ziyenera kusankhidwa malinga ndi momwe zinthu zilili kuti zitsimikizire kuti zinthuzo zikugwira ntchito bwino komanso zotsatira zake ndi zabwino kwambiri.
