FeCrAl alloy yog ib qho khoom siv ntau heev hauv kev siv hluav taws xob.

Vim tias nws muaj ntau yam zoo, tau kawg nws kuj muaj qhov tsis zoo, cia peb kawm txog nws.

Cov txiaj ntsig:

1, Qhov kub thiab txias siv hauv huab cua siab heev.

Qhov kub siab tshaj plaws ntawm HRE alloy hauv hlau-chromium-aluminium electrothermal alloy tuaj yeem ncav cuag 1400 ℃, thaum Cr20Ni80 alloy hauv nickel-chromium electrothermal alloy tuaj yeem ncav cuag 1200 ℃.

2, Lub neej ntev kev pabcuam

Nyob rau hauv tib lub kub siab hauv huab cua, lub neej ntawm Fe-Cr-Al tuaj yeem ntev dua 2-4 npaug ntawm Ni-Cr.

3, Kev thauj khoom siab

Vim tias Fe-Cr-Al alloy tso cai rau qhov kub thiab txias siab thiab lub neej ntev, qhov hnyav ntawm cov khoom siv tuaj yeem siab dua, uas tsis yog tsuas yog ua rau qhov kub nce sai dua, tab sis kuj tseem txuag cov khoom siv alloy.

4, Kev tiv thaiv oxidation zoo

Cov qauv zaj duab xis Al2O3 oxide uas tsim rau ntawm qhov chaw ntawm Fe-Cr-Al alloy yog compact, muaj kev nplaum zoo nrog lub substrate, thiab tsis yooj yim ua rau muaj kuab paug vim muaj kev tawg. Tsis tas li ntawd, Al2O3 muaj qhov tsis kam siab thiab qhov chaw yaj, uas txiav txim siab tias zaj duab xis Al2O3 oxide muaj kev tiv thaiv oxidation zoo heev. Qhov kev tiv thaiv carburizing kuj zoo dua li Cr2O3 uas tsim rau ntawm qhov chaw ntawm Ni-Cr alloy.

5, Me me tshwj xeeb gravity

Qhov hnyav tshwj xeeb ntawm Fe-Cr-Al alloy yog me dua li ntawm Ni-Cr alloy, uas txhais tau tias nws pheej yig dua los siv Fe-Cr-Al alloy dua li Ni-Cr alloy thaum ua cov khoom sib xws.

6, Kev tiv taus siab

Qhov resistivity ntawm Fe-Cr-Al alloy siab dua li ntawm Ni-Cr alloy, yog li cov khoom siv alloy loj dua tuaj yeem xaiv thaum tsim cov khoom, uas yog qhov zoo rau kev ua haujlwm ntev ntawm cov khoom, tshwj xeeb tshaj yog rau cov hlau alloy zoo. Thaum cov ntaub ntawv nrog tib cov lus qhia raug xaiv, qhov siab dua qhov resistivity, ntau cov khoom yuav raug cawm, thiab qhov me dua qhov chaw ntawm cov khoom hauv lub cub tawg yuav yog. Tsis tas li ntawd, qhov resistivity ntawm Fe-Cr-Al alloy tsis cuam tshuam los ntawm kev ua haujlwm txias thiab kev kho cua sov dua li ntawm Ni-Cr alloy.

7, Zoo sulfur tsis kam

Hlau, chromium thiab txhuas muaj kev tiv thaiv corrosion zoo rau huab cua uas muaj sulfur thiab thaum qhov chaw muaj kuab paug los ntawm cov tshuaj sulfur, nickel thiab chromium yuav raug eroded hnyav.

8, Tus nqi pheej yig

Hlau-chromium-aluminium pheej yig dua li nickel-chromium vim tias nws tsis muaj nickel tsawg.

Qhov Tsis Zoo:

1, Lub zog qis thaum kub siab

Nws qhov plasticity nce ntxiv nrog rau qhov kub nce. Thaum qhov kub siab tshaj 1000 ℃, cov khoom yuav maj mam ncab vim nws qhov hnyav, uas yuav ua rau lub ntsiab lus deformation.

2, Yooj yim kom tau txais brittleness loj

Tom qab siv rau qhov kub siab ntev thiab txias hauv lub cub tawg, nws yuav tawg yooj yim thaum cov noob loj hlob, thiab nws tsis tuaj yeem khoov tau thaum txias.

3, Sib Nqus

Fecral alloy yuav tsis yog hlau nplaum tshaj 600 ° C.

4, Kev tiv thaiv corrosion yog weaker dua li nicr alloy.
