Ka wehewehe nui
Hana ʻia ʻo FeCrAl alloy e kahi mea wela kiʻekiʻe, ferritic iron-chromium-aluminium alloy hiki ke hoʻohana ʻia i nā mahana a hiki i 1350 degere. ʻO nā noi maʻamau no 0Cr21Al6Nb e like me nā mea hoʻomehana uila i nā umu wela wela i ka mālama wela, nā seramika, ke aniani, ke kila, a me nā ʻoihana uila.
Hiʻona:
Me ka lōʻihi o ka lawelaweʻana i ke ola.ʻO ka wela wikiwiki.High thermal efficiency.Temperature uniformity. Hiki ke hoʻohana i ka vertically. Ke hoʻohana ʻia i ka volta helu, ʻaʻohe mea volatileuwea hoʻomehana uila. A he mea ʻē aʻe i ke kumu kūʻaiuwea nichrome. Hiki ke hoʻopilikinoʻia e like me nā koi o ka mea kūʻai
Hōʻike ʻia nā alloys FeCrAl e ka pale ʻana i ka oxidation maikaʻi loa a me ke ʻano kūpaʻa maikaʻi loa e hopena ai i ke ola o ka element lōʻihi.
Hoʻohana maʻamau lākou i nā mea hoʻomehana uila i nā umu ahi a me nā mea hana hale.
Fe-Cr-Al alloy me ke kiʻekiʻe resistivity a me ka lawelawe lawelawe ma mua o kēlā no ka NiCr alloy a he haʻahaʻa hoʻi ke kumu kūʻai.
Nā noi
0Cr21Al6 Iron-chrome-aluminium pale pale pale uila i hoʻohana nui ʻia no ka hana ʻana i nā mea hoʻomehana uila i nā mea pono home a me nā umu ahi. ʻO nā noi maʻamau he mau hao pālahalaha, mīkini hao, mea hoʻomehana wai, make molding plastic, hao hao, nā mea tubular sheathed metala a me nā mea pahu pahu.
wahi noi
Hoʻohana nui ʻia kā mākou huahana i nā lako hana wela, nā ʻāpana kaʻa, ka hao a me ka hana kila,
ʻoihana aluminika, nā mea hana metala, nā lako petrochemical, nā mīkini aniani, nā mīkini seramika,
mīkini meaʻai, mīkini lāʻau lapaʻau, a me ka ʻoihana ʻenehana mana.
