Ndi zidutswa zingati zomwe zili mu toni ya njerwa zomangira? Kuwerengera bwanji?

(1) Kodi osankhidwa refractory Njerwa ndi njerwa zotsekereza zopepuka zopepuka kapena zolemetsa zolemera kwambiri zopinga kutentha. Njerwa zonyezimira zopepuka zopepuka zimatanthawuza njerwa zosasunthika zokhala ndi mphamvu zosakwana 1300Kg/m³. Njerwa zonyezimira zopepuka zimakhala ndi mawonekedwe otsika kachulukidwe, porosity yayikulu, kutsika kwamafuta, kusungirako bwino kutentha, ndi mphamvu zina zopondereza, motero zagwiritsidwa ntchito kwambiri pazida zochizira kutentha. Njerwa zolemera kwambiri zotentha kwambiri ndi njerwa zomangira zomwe zimakhala ndi kachulukidwe kochulukirapo kuposa 1800Kg/m³ ndipo ndizoyenera kugwiritsidwa ntchito pokhudzana ndi kutentha kwambiri. Pazida ziwirizi, choyamba muyenera kudziwa kuchuluka kwa njerwa zomwe mumasankha.

(2) Kukula ndi mawonekedwe a njerwa zomangira zomwe ziyenera kugulidwa ziyenera kudziwa ngati njerwa zomangira zomwe ziyenera kugulidwa ndi njerwa zomangira zooneka mwapadera kapena mitundu yodziwika bwino ya njerwa zomangira. Kupyolera mu chitsanzo, kukula ndi ndondomeko ya njerwa yotsutsa imatha kumveka ndipo kuchuluka kwake kungathe kuwerengedwa.

(3) Mawerengereni kulemera kwa unit wa njerwa refractory anagulidwa kuchokera kachulukidwe odziwika ndi kuchuluka kwa njerwa refractory molingana ndi chilinganizo ambiri ntchito powerengera kulemera kwa unit, ndi mawerengedwe njira ya unit kulemera = voliyumu x kachulukidwe, ndipo potsiriza kudziwa zingati. zidutswa za tani.
