FeCrAl alloy yakajairika mumagetsi kupisa munda.

Nekuti ine akawanda mabhenefiti, hongu zvakare ine zvayakaipira, rega kuidzidza.

Zvakanakira:

1,Tembiricha yekushandisa mumhepo yakakwira.

Iyo yakanyanya kupisa tembiricha yeHRE alloy mu iron-chromium-aluminium electrothermal alloy inogona kusvika 1400 ℃, nepo iyo yeCr20Ni80 alloy mu nickel-chromium electrothermal alloy inogona kusvika 1200 ℃.

2, Hupenyu hurefu hwebasa

Pasi peiyo tembiricha yebasa repamusoro mumhepo, hupenyu hweFe-Cr-Al hunogona kuita 2-4 nguva yakareba kupfuura iyo yeNi-Cr element.

3,Mutoro wepamusoro wepamusoro

Nekuti Fe-Cr-Al alloy inobvumira tembiricha yepamusoro uye hupenyu hurefu hwesevhisi, chikamu chepamusoro chinotakura chinogona kunge chakakwira, izvo zvisingaite chete kuti tembiricha ikwire nekukurumidza, asi zvakare inochengetedza alloy zvinhu.

4, Yakanaka oxidation kuramba

Iyo Al2O3 oxide firimu chimiro chakaumbwa pamusoro peFe-Cr-Al alloy yakasungirirwa, ine yakanaka adhesion ne substrate, uye haisi nyore kukonzera kusvibiswa nekuda kwekupararira. Uye zvakare, Al2O3 ine yakakwira resistivity uye yekunyungudika, iyo inosarudza kuti Al2O3 oxide firimu ine yakanakisa oxidation kuramba. Iyo carburizing kuramba iri nani pane Cr2O3 yakaumbwa pamusoro peNi-Cr alloy.

5,Diki chaiyo giravhiti

Iyo chaiyo gravity yeFe-Cr-Al alloy idiki pane iyo yeNi-Cr alloy, zvinoreva kuti zvine mari yakawanda kushandisa Fe-Cr-Al alloy pane Ni-Cr alloy paunenge uchigadzira zvimwe chete zvikamu.

6, High resistivity

Iyo resistivity yeFe-Cr-Al alloy yakakwirira kupfuura iyo yeNi-Cr alloy, saka yakakura alloy zvinhu zvinogona kusarudzwa paunenge uchigadzira zvikamu, izvo zvinobatsira kurebesa hupenyu hwesevhisi yezvikamu, kunyanya kune yakanaka alloy waya. Kana zvinhu zvine zvirevo zvakafanana zvakasarudzwa, iyo yakakwirira yekudzivirira, iyo yakawanda zvinhu ichaponeswa, uye diki nzvimbo yezvikamu muchoto ichave. Mukuwedzera, iyo resistivity yeFe-Cr-Al alloy haina kukanganiswa nekushanda kunotonhora uye kupisa kupisa kupfuura iyo yeNi-Cr alloy.

7, Yakanaka sarufa kuramba

Simbi, chromium nearuminiyamu zvine kusimba kwakanaka kwekuora kumhepo ine sulfuri uye kana pamusoro pasvibiswa nezvinhu zvine sarufa, nepo nickel nechromium zvichanyungudutswa zvakanyanya.

8,Cheap mutengo

Iron-chromium-aluminium yakachipa zvakanyanya pane nickel-chromium nekuti haina nickel shoma.

Zvakaipa:

1,Simba rakaderera pakupisa kwakanyanya

Plasticity yaro inowedzera nekuwedzera kwekushisa. Kana tembiricha iri pamusoro pe1000 ℃, zvinhu zvacho zvinotambanuka zvishoma nezvishoma nekuda kwehuremu hwayo, izvo zvinokonzeresa deformation yechinhu.

2, Zviri nyore kuwana brittleness yakakura

Mushure mekushandiswa pakupisa kwepamusoro kwenguva yakareba uye yakanyoroveswa muchoto, inova brittle sezvo zviyo zvinokura, uye hazvigone kukotama mukutonhora.

3, Magnetic

Fecral alloy ichave isiri-magnetic pamusoro pe600 ° C.

4, Corrosion kuramba haina kusimba pane nicr alloy.

Kana uine rumwe ruzivo, unogamuchirwa kukurukura nesu.

Tinogona kugadzira anenge 200 matani fecral alloy zvigadzirwa, kana uchida, ndapota inzwa wakasununguka kutibata nesu.
