Njerwa za Alumina Refractory mu Viwanda Zitsulo

Alumina refractory njerwa ndi mtundu wa zinthu refractory ntchito mu makampani zitsulo. Njerwazi zimapangidwa ndi aluminiyamu, chinthu chomwe chimalimbana kwambiri ndi kutentha, dzimbiri, komanso kutha. Njerwa za aluminiyamu zimagwiritsidwa ntchito m'makampani opanga zitsulo kupanga zingwe ndi zotchingira ng'anjo, ng'anjo, ndi zida zina zotentha kwambiri. Njerwa za aluminiyani zimalimba kwambiri ndipo zimapereka kutsekemera kwapamwamba kwambiri komanso kukana dzimbiri. Njerwazi zimatha kupirira kutentha mpaka 2000°C (3632°F). The zakuthupi mkulu matenthedwe madutsidwe kumathandiza kuchepetsa kugwiritsa ntchito mphamvu ndi kuonjezera dzuwa. Njerwa za alumina refractory zimakhala ndi mlingo waukulu wa kukana kwa mankhwala, ndipo zimatha kupirira chilengedwe chowononga cha kupanga zitsulo. Zinthuzi zimalimbananso kwambiri ndi abrasion ndi kuvala, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito potentha kwambiri. Njerwa za alumina refractory zimapezeka m'mawonekedwe ndi makulidwe osiyanasiyana, kuphatikiza midadada, ma cubes, ndi matabwa. Njerwazo zimatha kudulidwa ndikupangidwa kuti zigwirizane ndi miyeso yeniyeni ya ng'anjo kapena ng'anjo. Njerwazi zimagwiritsidwa ntchito poyala makoma, denga, ndi pansi pa nyumbayo. Alumina refractory njerwa nthawi zambiri amagwiritsidwa ntchito muzitsulo ndi maziko. Amagwiritsidwa ntchito kuyika makoma, pansi, ndi denga la ng'anjo, ng'anjo, kapena zipangizo zina. Njerwazi zimagwiritsidwanso ntchito pazinthu zina monga kuyika makoma a ng'anjo zophulika, ma ladles, ndi zosinthira. Njerwa za alumina refractory nthawi zambiri zimapangidwa kuchokera kusakaniza kwa alumina, silika, ndi magnesia. Njerwazo zimawotchedwa potentha kwambiri kuti zipange zinthu zowundana komanso zolimba. Njerwazi zimathanso kuphatikizidwa ndi zida zina, monga silicon carbide, kuti ziwonjezere kukana kwa zinthuzo kuti zisawonongeke komanso kuvala. Alumina refractory njerwa ndizofunikira kwambiri pamakampani azitsulo. Pamene mafakitale azitsulo akupitirizabe kusintha ndi kupanga zatsopano, kugwiritsa ntchito njerwazi kudzakhala kofala kwambiri. Njerwazi zimapereka kutentha kwapamwamba kwambiri komanso kukana kwa dzimbiri, zomwe zimawapangitsa kukhala abwino kwambiri pakupanga zitsulo.
