0Cr15Al5 FeCrAl Alloy Heat Resistance Waya fun Ileru Alapapo Iṣẹ
Resistance waya ti wa ni maa lo ni resistor. Atako wa ni ifarada kekere lori iwọn ati iye resistance itanna
1) Ohun elo ti o wa:
Cr20Ni80, Cr30Ni70, Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr20Ni25, NiCr25FeAlY, Cr13Al4, Cr21Al4, Cr14Al4, Cr20Al4, Cr21Al6, Cr25Al6, Cr25Al1 .
2) Apẹrẹ:
Waya, rinhoho, tẹẹrẹ, dì, okun
3) Nipa wa:
A tun le ṣe apẹrẹ ati iṣelọpọ ni ibamu si ibeere rẹ. Shanghai Tankii Alloy Material Co., Ltd jẹ amọja ni iṣelọpọ ti Ni-Cr Alloy, Cu-Ni Alloy, Fechral, okun waya thermocouple, nickel mimọ ati awọn ohun elo alloy pipe miiran ni irisi okun waya, rinhoho, ọpa, igi ati awo.
4) Ohun kikọ alloy:
Ferritic alloys gba laaye lati de awọn iwọn otutu ilana ti 2192 si 2282F,
Ni ibamu si iwọn otutu resistance ti 2372F. Gbogbo awọn ohun alumọni ferritic ni isunmọ ipilẹ ipilẹ kanna: 20 si 25% ti chromium, 4.5 si 6% ti aluminiomu, iwọntunwọnsi jẹ irin. Diẹ ninu wọn ni ni afikun ilẹ toje, bi yttrium tabi silicium. Awọn alloy wọnyẹn ti o ni eto ferritic, a ṣe akiyesi, lẹhin itọju kan ni iwọn otutu ti nṣiṣẹ giga, idagbasoke pataki ti ọkà ati ojoriro ti awọn carbide chromium ni ipele awọn isẹpo ọkà. Eyi nfa idamu ti o pọ si ti resistance, paapaa nigbati o ba tun wa ni iwọn otutu ibaramu.
