FeCrAl alloy 0cr21al6Nb Spiral uila hiln pumehana wili pumehana
0Cr21Al6Nbhe hao-chromium-aluminium alloy (FeCrAl alloy) no ka hoʻohana ʻana i nā mahana a hiki i 1350°C (2550°F). ʻO ka huila me nā hiʻohiʻona o ka resistivity kiʻekiʻe, ka helu haʻahaʻa haʻahaʻa o ke kūpaʻa uila, ka mahana hana kiʻekiʻe, ke kūpaʻa oxidation maikaʻi ma lalo o ke kiʻekiʻe kiʻekiʻe. Hiki ke like me kanthal A1, Alloy875, Resistohm 145, Aluchrom0, Alchrome875, MWS-875, Stablohm875.
Hoʻohana nui ʻia ia i ka umu uila ʻoihana, nā mea uila hale a me nā mea uila mamao infrared.
E like me nā mea hoʻomehana panel, nā mea hoʻomehana infrared, nā papa hoʻomehana, i nā mea hoʻomehana pahu, nā mea hoʻomehana mālama, nā mea hoʻomehana seramika no ka kuke ʻana i nā pā, nā mea kilns, nā radiators, i loko o ka quartz tube heaters no ka hoʻomehana ākea, nā mea hoʻoheheʻe, nā umu toaster, nā mea hoʻomaloʻo infrared ʻoihana, nā coils ma ka ceramic molded. pulupulu no ka kuke ʻana i nā pā me nā ʻuala seramika a pēlā aku.
