Uea FeCrAl

ʻO ka hao-chromium-aluminum uea he lōʻihi ke ola lawelawe, kiʻekiʻe ili haawe, maikaʻi oxidation kū'ē, kiʻekiʻe resistivity, haʻahaʻa kumu kūʻai, a me ka maikaʻi corrosion kū'ē i kiʻekiʻe wela. Uea FeCrAl He mea kūpono loa ia no ka hoʻohana ʻana i nā lewa i loaʻa i ka sulfur a me ka sulfide, a loaʻa ka māmā kikoʻī a me ka ʻili e hōʻike ana i kahi ʻano o nā mea maikaʻi e like me ka ukana kiʻekiʻe, ke ola lōʻihi o ka lawelawe ʻana, a me ke kumu kūʻai haʻahaʻa, ʻo ka hao-chromium-aluminum uea he mea hoʻomehana kūpono i ka ʻoihana. nā kapuahi uila, nā mea hana hale, a me nā mea hana infrared mamao.

Loaʻa i ka alloy nā waiwai mechanical maikaʻi a hiki ke kū i kekahi mau ikaika tensile a compressive. He paʻakikī koʻikoʻi a hiki ke pale aku i ka hopena o waho a ʻaʻahu i kekahi ʻano. Eia kekahi, loaʻa iā ia kahi helu heheʻe kiʻekiʻe a me nā waiwai hoʻonui wela maʻalahi, e ʻae iā ia e mālama i ke kūpaʻa maikaʻi ma nā wahi wela kiʻekiʻe.

Ma kaʻoihanaʻoihana, hoʻohana pinepineʻia i ka hanaʻana i nā mea hoʻomehana i nā kapuahi uila, nā mea hana wela, nā lako petrochemical, a me nā mea'ē aʻe. , etc. Eia kekahi, hoʻohana nui ʻia ʻo FeCrAl i nā mea uila, nā ʻāpana kaʻa a me nā māla ʻē aʻe.

Product Information

Nā mea kanu hoʻohui:

ʻO ka hui kemika o Uea FeCrAl Ua like penei:

1. ʻO ka hao (Fe): e helu ana ma kahi o 70% o ka haku mele, ʻo ia kekahi o nā mea nui o ka mea hoʻohui a hāʻawi i nā waiwai kumu o ka hui.

2. Chromium (Cr): e helu ana ma kahi o 25% o ka haku mele, e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion a me ka hana wela kiʻekiʻe o ka alloy.

3. Aluminum (Al): e helu ana ma kahi o 5% o ka haku mele, e hoʻomaikaʻi ai i ka pale ʻana o ka oxidation a me ke kūpaʻa wela kiʻekiʻe o ka alloy.

Hoʻoholo ka ʻenekini kemika o FeCrAl i nā ʻano o ka huila i kekahi ʻano, e like me ka resistivity, coefficient mahana o ke kūpaʻa, nā waiwai mechanical a me ke kūpaʻa corrosion.

Pono e hoʻomaopopo ʻia e ʻokoʻa paha ke ʻano kemika kikoʻī o ka alloy ma muli o ka mea hana a me nā kikoʻī huahana. ʻO ka mea i luna he ratio haku mele maʻamau. Ma nā noi maoli, ka haku mele o ka Uea FeCrAl hiki ke hoʻololi ʻia ma muli o nā pono kikoʻī a me nā koi.

Kino waiwai:

Loaʻa iā ia nā waiwai kino:

1. Density: ʻO ka nui e pili ana i 7.10g / cm³, he kiʻekiʻe kiʻekiʻe.

2. Ka helu hoʻoheheʻe: ʻO ka helu hoʻoheheʻe o ka mea hoʻoheheʻe e pili ana i 1500 ° C, kahi kiʻekiʻe o ka heheʻe.

3. ʻO ka hoʻonui ʻana o ka wela: ʻO ka mea hoʻonui wela o ka huila e pili ana i 13.5 × 10-6 / ° C, nona nā waiwai hoʻonui wela.

4. Thermal conductivity: He kiʻekiʻe ka hoʻoili wela o ka Alloy a hiki ke hana koke i ka wela.

5. Resistivity: He kiʻekiʻe ka pale ʻana o ka alloy a hiki ke hoʻohua i ka wela no ka wela.

6. Mechanical waiwai: Ua loaʻa i ka alloy kekahi ikaika tensile a me ka ikaika hua, a hiki ke pale aku i kekahi mau tensile a compressive ikaika.

7. Ke kū'ēʻana i ke kino: He maikaʻi ke kūpaʻaʻana o ka huila a hiki ke mālama i ka paʻa ma lalo o nāʻano kaiapuni likeʻole.

Ma muli o nā waiwai kino i luna, Uea FeCrAl kūpono ia no ka hana ʻana i nā mea hoʻomehana i nā wahi wela kiʻekiʻe, me ka coefficient mahana paʻa o ke kūpaʻa a me ke ola lawelawe lōʻihi.
