Ingxubevange ye-FeCrAl ivame kakhulu endaweni yokushisisa ugesi.

Ngoba inezinzuzo eziningi, yiqiniso futhi inobubi, ake uyifunde.

Izinzuzo:

1, izinga lokushisa lokusetshenziswa emkhathini liphezulu.

Izinga lokushisa eliphezulu lesevisi ye-HRE ingxubevange ye-iron-chromium-aluminium electrothermal alloy lingafinyelela ku-1400℃, kuyilapho lelo lika-Cr20Ni80 ingxubevange ku-nickel-chromium electrothermal alloy lingafinyelela ku-1200℃.

2,Impilo ende yesevisi

Ngaphansi kwezinga lokushisa elifanayo lesevisi ephezulu emkhathini, impilo yesici se-Fe-Cr-Al ingaba yinde ngokuphindwe izikhathi ezingu-2-4 kunento ye-Ni-Cr.

3, Umthwalo ophezulu wamanzi

Ngenxa yokuthi i-Fe-Cr-Al alloy ivumela izinga lokushisa eliphezulu lesevisi nempilo ende yesevisi, umthwalo wengxenye yengxenye ungaba phezulu, ongenzi nje kuphela ukuthi izinga lokushisa likhuphuke ngokushesha, kodwa futhi ligcina izinto ze-alloy.

I-4, ukumelana okuhle kwe-oxidation

Isakhiwo sefilimu ye-Al2O3 oxide esakhiwe ebusweni be-Fe-Cr-Al alloy sihlangene, sinokunamathela okuhle ne-substrate, futhi akulula ukubangela ukungcola ngenxa yokuhlakazeka.Ngaphezu kwalokho, i-Al2O3 ine-resistivity ephezulu kanye nephuzu elincibilikayo, elinquma ukuthi ifilimu ye-Al2O3 oxide inokumelana okuhle kakhulu kwe-oxidation.Ukumelana ne-carburizing nakho kungcono kune-Cr2O3 eyenziwe ebusweni be-Ni-Cr alloy.

5,Amandla adonsela phansi amancane

Amandla adonsela phansi athile engxubevange ye-Fe-Cr-Al mancane kunalawo engxubevange ye-Ni-Cr, okusho ukuthi ukonga kakhulu ukusebenzisa ingxubevange ye-Fe-Cr-Al kunealloy ye-Ni-Cr lapho kwenziwa izingxenye ezifanayo.

6, ukumelana okuphezulu

I-resistiveivity ye-Fe-Cr-Al alloy iphakeme kune-alloy ye-Ni-Cr, ngakho-ke izinto ze-alloy ezinkulu zingakhethwa uma uklama izingxenye, okuzuzisayo ukwandisa impilo yesevisi yezingxenye, ikakhulukazi izintambo ze-alloy emihle.Lapho izinto zokwakha ezinezincazelo ezifanayo zikhethiwe, ukuphakama kwe-resistant, izinto eziningi zizosindiswa, futhi indawo encane yezingxenye esithandweni sizoba.Ngaphezu kwalokho, ukumelana ne-Fe-Cr-Al alloy akuthinteki kangako ekusebenzeni okubandayo nokwelashwa kokushisa kunaleyo ye-Ni-Cr alloy.

7,Ukumelana okuhle nesibabule

I-ayoni, i-chromium ne-aluminium zikwazi ukumelana nokugqwala okuhle emkhathini oqukethe isulfure nalapho indawo engaphezulu ingcoliswa izinto ezinesulfure, kuyilapho i-nickel ne-chromium kuzoguguleka kakhulu.

8,Intengo eshibhile

I-Iron-chromium-aluminium ishibhe kakhulu kune-nickel-chromium ngoba ayinayo i-nickel eyivelakancane.

Ububi:

1, Amandla aphansi ekushiseni okuphezulu

Ipulasitiki yayo iyanda ngokunyuka kwezinga lokushisa.Uma izinga lokushisa lingaphezu kuka-1000 ℃, izinto zizokwelula kancane ngenxa yesisindo sazo, okuzodala ukuwohloka kwesici.

2,Kulula ukuthola ukuqina okukhulu

Ngemva kokusetshenziswa ekushiseni okuphezulu isikhathi eside futhi kupholiswe esithandweni, kuba brittle njengoba okusanhlamvu kukhula, futhi akukwazi ukugoba esimweni esibandayo.

3, Magnetic

Ingxubevange ye-Fecral ngeke ibe yizibuthe ngaphezu kuka-600°C.

4, Ukumelana nokugqwala kubuthakathaka kune-nicr alloy.

Uma unolwazi oluthe xaxa, wamukelekile ukuxoxa nathi.

Singakhiqiza amathani angama-200 imikhiqizo ye-fecral alloy, uma uyidinga, sicela ukhululeke ukuxhumana nathi.
