Hana ʻia nā uea Fe-Cr-Al i ka hao chromium aluminum base alloys i loaʻa nā mea liʻiliʻi o nā mea reactive e like me ka yttrium a me ka zirconium a hana ʻia e ka hoʻoheheʻe ʻana, ka ʻōwili kila, forging, annealing, drawing, surface treatment, resistance control test, etc.
ʻO ka maʻiʻo alumini kiʻekiʻe, i hui pū ʻia me ka maʻiʻo chromium kiʻekiʻe e hiki ke piʻi ka mahana scaling i 1425ºC (2600ºF);
Ua hana ʻia ka uea Fe-Cr-Al e ka mīkini hoʻoluʻu ʻokoʻa kiʻekiʻe e hoʻomalu ʻia ai ka mana mana e ke kamepiula, loaʻa iā lākou ma ke ʻano he uea a me ka lipine.

FeCrAl Electrictrical Resistance ʻO nā mea hoʻomehana wela me ke kiʻekiʻe o ka uila ke kū'ē, he liʻiliʻi ke koena wela o ke kū'ē, kiʻekiʻe ka wela hana. maikaʻi corrosion kū'ē ma lalo o ke kiʻekiʻe wela, a oi loa kūpono no ka hoʻohana 'ana i loko o ke kinoea i loko o ka sulfur a me ka sulfides, kumu kūʻai haʻahaʻa, ua hoʻohana nui ia i loko o ka 'oihana umu uila, hale lako, mamao infrared mea pono hoʻomehana mea.
ʻAno FeCrAl:1Cr13AI4, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb, 0Cr27AI7Mo2 etc.

Palapala noi
ʻO kā mākou huahana (FeCrAl) hiki ke kūʻai ʻia a hoʻohana nui ʻia no ka hana ʻana i nā mea hoʻomehana e like me ka umu ahi, nā mea hoʻomehana kīwila, nā mea pale uila like ʻole a me ka locomotive braking resistor, nā lako infrared, liquefied gas infrared heat-resisting net, nā ʻano like ʻole. ka hoʻā ʻana a me ka hoʻomālamalama ʻana i nā electrodes a me nā resistors e hoʻoponopono ana i ka voltage no nā kaʻa a me nā mea ʻē aʻe i nā mīkini Metallurgical, lāʻau lapaʻau, kemika, keramika, uila, nā mea uila, aniani a me nā ʻoihana kīwila a ʻoihana ʻē aʻe.

Nā ʻano huahana a me ka laulā nui
uwea poepoe
0.010-12 mm (0.00039-0.472 iniha) loaʻa nā nui ʻē aʻe ma ke noi.

Lipine (uea paʻa)
Mānoanoa: 0.023-0.8 mm (0.0009-0.031 iniha)
Laulā: 0.038-4 mm (0.0015-0.157 iniha)
Lakiō laula/mānoanoa max 60, e pili ana i ka alloy a me ka hoʻomanawanui
Loaʻa nā nui ʻē aʻe ma ke noi.

Ke kū'ē uila hoʻomehana uea i ikaika antioxidant waiwai, akā, i kekahi mau kinoea i loko o ka umu e like me ka ea, kalapona, sulfur, hydrogen a me naikokene lewa, mau nō kekahi hopena ma luna o ia.

ʻOiai ua loaʻa i kēia mau uea hoʻomehana ka mālama antioxidant, ʻo ka lawe ʻana, ka wili ʻana, ka hoʻonohonoho ʻana a me nā kaʻina hana ʻē aʻe e hōʻeha i kekahi ʻano a hōʻemi i kona ola lawelawe.

I mea e hoʻonui ai i ke ola lawelawe, pono nā mea kūʻai aku e hana i ka mālama pre oxidation ma mua o ka hoʻohana ʻana. ʻO ke ʻano o ka hoʻomehana ʻana i nā mea hoʻohui i hoʻokomo piha ʻia i loko o ka ea maloʻo a hiki i ka mahana (lalo 100-200C ma mua o kona kiʻekiʻe e hoʻohana ana i ka mahana), mālama ʻia ka wela no 5 a 10 mau hola, a laila hoʻomaha mālie me ka umu.
