I-alloy ye-FeCrAl ixhaphake kakhulu kwiindawo zokufudumeza ngombane.

Ngenxa yokuba ineenzuzo ezininzi, ewe ikwanazo neengxaki, masiyifunde.

Iingenelo:

1, Ubushushu bokusetyenziswa emoyeni buphezulu.

Ubushushu obuphezulu benkonzo ye-HRE alloy kwi-iron-chromium-aluminium electrothermal alloy bunokufikelela kwi-1400℃, ngelixa obo be-Cr20Ni80 alloy kwi-nickel-chromium electrothermal alloy bunokufikelela kwi-1200℃.

2, Ubomi benkonzo ende

Phantsi kobushushu obufanayo obuphezulu benkonzo emoyeni, ubomi be-Fe-Cr-Al element bunokuba bude ngokuphindwe kabini ukuya kane kunobo be-Ni-Cr element.

3, Umthwalo ophezulu womphezulu

Ngenxa yokuba i-Fe-Cr-Al alloy ivumela ubushushu obuphezulu benkonzo kunye nobomi benkonzo ende, umthwalo womphezulu wecandelo unokuba phezulu, nto leyo engenzi nje kuphela ukuba ubushushu bunyuke ngokukhawuleza, kodwa ikwagcina izinto ze-alloy.

4, Ukumelana okuhle kwe-oxidation

Isakhiwo sefilimu ye-Al2O3 oxide esenziwe phezu komphezulu we-Fe-Cr-Al alloy sincinci, sinamathele kakuhle kwi-substrate, kwaye akulula ukubangela ungcoliseko ngenxa yokusasazeka. Ukongeza, i-Al2O3 ine-resistivity ephezulu kunye nendawo yokunyibilika, nto leyo egqiba ukuba ifilimu ye-Al2O3 oxide inokumelana okuhle kakhulu ne-oxidation. Ukumelana ne-carburizing kukwangcono kune-Cr2O3 eyenziwe kumphezulu we-Ni-Cr alloy.

5, Ubunzima obuncinci obuthile

Ubunzima obuthile be-Fe-Cr-Al alloy buncinci kunobo be-Ni-Cr alloy, oko kuthetha ukuba kungabizi kakhulu ukusebenzisa i-Fe-Cr-Al alloy kune-Ni-Cr alloy xa kusenziwa izinto ezifanayo.

6, Ukumelana okuphezulu

Ukumelana kwe-Fe-Cr-Al alloy kuphezulu kune-Ni-Cr alloy, ngoko ke izinto ze-alloy ezinkulu zinokukhethwa xa kuqulunqwa izinto, nto leyo eluncedo ekwandiseni ubomi benkonzo yezinto, ingakumbi kwiingcingo ze-alloy ezincinci. Xa kukhethwa izinto ezineenkcazo ezifanayo, kokukhona ukumelana okuphezulu, kokukhona izinto ezininzi ziya kugcinwa, kwaye kokukhona indawo yezixhobo kwi-oven iya kuba ncinci. Ukongeza, ukumelana kwe-Fe-Cr-Al alloy akuchaphazeleki kangako kukusebenza okubandayo kunye nonyango lobushushu kunaleyo ye-Ni-Cr alloy.

7, Ukumelana okuhle kwesalfure

I-iron, i-chromium kunye ne-aluminium zinokumelana kakuhle nokugqwala kwi-atmosphere equlethe i-sulfur kwaye xa umphezulu ungcoliswe zizinto ezine-sulfur, ngelixa i-nickel kunye ne-chromium ziya kukhukuliseka kakhulu.

8, Ixabiso eliphantsi

I-iron-chromium-aluminium ixabisa kancinci kune-nickel-chromium kuba ayinayo i-nickel enqabileyo.

Iingxaki:

1, Amandla aphantsi kubushushu obuphezulu

Ukuqina kwayo kuyanda xa ubushushu bunyuka. Xa ubushushu bungaphezulu kwe-1000℃, izinto ziya kutsaleka kancinci ngenxa yobunzima bazo, nto leyo eya kubangela ukuguquka kwento.

2, Kulula ukufumana ubuqhophololo obukhulu

Emva kokusetyenziswa kubushushu obuphezulu ixesha elide kwaye kupholiswe esitovini, iba buthathaka njengoko iinkozo zikhula, kwaye ayinakugotywa xa ibanda.

3, Imagnethi

I-alloy ye-fecral ayizukuba nemagnethi engaphezulu kwama-600°C.

4, Ukumelana nokugqwala kubuthathaka kune-nicr alloy.

Ukuba unolwazi oluthe kratya, wamkelekile ukuba uxoxe nathi.

Singavelisa malunga neetoni ezingama-200 zeemveliso ze-fecral alloy, ukuba uyayifuna, nceda uzive ukhululekile ukuqhagamshelana nathi.
