He mea maʻamau ka FeCrAl alloy ma ke kahua hoʻomehana uila.

No ka mea he nui kona mau pono, ʻoiaʻiʻo nō hoʻi nā hemahema, e aʻo iā ia.

Pono:

1, He kiʻekiʻe ka mahana hoʻohana i ka lewa.

ʻO ka mahana lawelawe kiʻekiʻe loa o ka HRE alloy i ka hao-chromium-aluminum electrothermal alloy hiki ke hiki i 1400 ℃, aʻo ka Cr20Ni80 alloy i ka nickel-chromium electrothermal alloy hiki ke hiki i 1200 ℃.

2,Loaʻa ke ola lawelawe

Ma lalo o ka mahana lawelawe kiʻekiʻe like i ka lewa, hiki ke ola o ka mea Fe-Cr-Al i 2-4 mau manawa ma mua o ko Ni-Cr element.

3, Haawe ili kiʻekiʻe

No ka mea hiki i ka Fe-Cr-Al alloy ke kiʻekiʻe o ka lawelawe lawelawe a me ka lōʻihi o ka lawelawe ʻana, hiki ke kiʻekiʻe ke kiʻekiʻe o ka haʻahaʻa o ka ʻili, ʻaʻole ia e piʻi wikiwiki ka mahana, akā mālama pū kekahi i nā mea hao.

4, maikaʻi oxidation kū'ē

ʻO ka Al2O3 oxide kiʻiʻoniʻoni i hana ʻia ma luna o ka ʻili o ka Fe-Cr-Al alloy he paʻa, he adhesion maikaʻi me ka substrate, a ʻaʻole maʻalahi ke kumu o ka pollution ma muli o ka lūlū ʻana. Eia kekahi, Al2O3 he kiʻekiʻe resistivity a me ka helu heheʻe, e hoʻoholo i ka Al2O3 oxide kiʻiʻoniʻoni i maikai oxidation kū'ē. ʻOi aku ka maikaʻi o ke kūpaʻa carburizing ma mua o Cr2O3 i hana ʻia ma ka ʻili o ka alloy Ni-Cr.

5,ʻuʻuku kiko'ī liʻiliʻi

ʻOi aku ka liʻiliʻi o ka ʻumekaumaha kikoʻī o ka alloy Fe-Cr-Al ma mua o ka alloy Ni-Cr, ʻo ia ka mea ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka alloy Fe-Cr-Al ma mua o ka alloy Ni-Cr i ka hana ʻana i nā ʻāpana like.

6, kiʻekiʻe resistivity

ʻOi aku ka kiʻekiʻe o ka pale o Fe-Cr-Al alloy ma mua o ka alloy Ni-Cr, no laila hiki ke koho ʻia nā mea hao nui i ka wā e hoʻolālā ai i nā ʻāpana, kahi mea e pono ai e hoʻolōʻihi i ke ola lawelawe o nā ʻāpana, ʻoi aku hoʻi no nā uwea alloy maikaʻi. Ke koho ʻia nā mea me nā kikoʻī like, ʻoi aku ka kiʻekiʻe o ka resistivity, ʻoi aku ka nui o nā mea e mālama ʻia, a ʻoi aku ka liʻiliʻi o ke kūlana o nā mea i loko o ka umu. Eia kekahi, ʻoi aku ka liʻiliʻi o ka resistivity o Fe-Cr-Al alloy e ka hana anu a me ka mālama wela ma mua o ka Ni-Cr alloy.

7, ʻO ke kūpaʻa sulfur maikaʻi

ʻO ka hao, ka chromium a me ka alumini ka maikaʻi o ka corrosion kū'ē i ka sulfur-containing ea a i ka wā e hoʻohaumia ʻia ai ka ʻili e nā mea i loaʻa i ka sulfur, ʻoiai e hoʻopau nui ʻia ka nickel a me ka chromium.

8, Kumukuai kūʻai

ʻOi aku ka maikaʻi o ka hao-chromium-aluminum ma mua o ka nickel-chromium no ka mea ʻaʻole i loaʻa i ka nickel liʻiliʻi.

Nā hemahema:

1, Haʻahaʻa ikaika i ke kiʻekiʻe wela

Piʻi kona plasticity me ka piʻi ʻana o ka mahana. Ke piʻi ka mahana ma luna o 1000 ℃, e hoʻolōʻihi ʻia ka mea ma muli o kona kaumaha ponoʻī, kahi e hoʻololi ai i ka mea.

2, maʻalahi e loaʻa i ka brittleness nui

Ma hope o ka hoʻohana ʻia ʻana i ka wela kiʻekiʻe no ka manawa lōʻihi a maʻalili i loko o ka umu ahi, lilo ia i mea palupalu i ka ulu ʻana o ka palaoa, ʻaʻole hiki ke hoʻopōloli ʻia i ke ʻano anuanu.

3, Magnetic

ʻAʻole ka magnetik ka Fecral alloy ma luna o 600°C.

4, ʻoi aku ka nāwaliwali o ka corrosion ma mua o ka alloy nicr.

Inā he ʻike hou aku kāu, e ʻoluʻolu e kūkākūkā me mākou.

Hiki iā mākou ke hana ma kahi o 200 tons fecral alloy products, inā makemake ʻoe, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
