Nhanganyaya kune Heating Alloys
Pakusarudza zvinhu zvekudziya zvinhu, maviri alloys anowanzo fungwa:Nichrome(Nickel-Chromium) uyeFeCrAl(Iron-Chromium-Aluminum). Nepo ese ari maviri achishandira zvinangwa zvakafanana mukudzivirira kudziyisa maapplication, ane akasiyana hunhu anoita kuti akwane kune akasiyana nharaunda uye mashandisirwo. Kunzwisisa misiyano iyi kwakakosha pakusarudza zvinhu zvakafanira kune zvaunoda chaizvo.
1.Composition uye Basic Properties
Nichrome is a nickel-chromium alloy kazhinji ine 80% nickel uye 20% chromium, kunyange mamwe maratio aripo. Uku kusanganiswa kunopa kumira kwakanaka kune oxidation uye inochengetedza simba pakupisa kwakanyanya. Nichrome alloys anozivikanwa nekuumbwa kwawo uye kuita zvinoenderana pahupamhi hwekushisa.
FeCrAl alloys, sezita rinoratidza, anonyanya kuumbwa nesimbi (Fe) ine akakosha ekuwedzera echromium (Cr) uye aluminium (Al). Chimiro chakajairika chinogona kunge chiri 72% iron, 22% chromium, uye 6% aluminium. Iyo aluminium yemukati inonyanya kuwedzera alloy's yepamusoro-tembiricha kuita uye oxidation kuramba.
2.Temperature Performance
Imwe yemisiyano yakanyanya kukosha iri mukupisa kwavo kwakanyanya kushanda:
- Nichrome inowanzoshanda kusvika ku1200 ° C (2192 ° F)
- FeCrAl inogona kumira tembiricha inosvika 1400°C (2552°F)
Izvi zvinoita kuti FeCrAl ive yepamusoro kune zvikumbiro zvinoda kupisa kwakanyanya, senge vira remaindasitiri kana midziyo yemurabhoritari inopisa.
3.Oxidation Resistance
Ose maalloys anoumba inodzivirira oxide layer, asi kuburikidza nenzira dzakasiyana:
- Nichrome inoumba chromium oxide layer
- FeCrAl inogadzira aluminium oxide (alumina) layer
Iyo alumina layer muFeCrAl yakagadzikana zvakanyanya pakupisa kwakanyanya, ichipa zvirinani zvenguva refu dziviriro kubva kune oxidation uye ngura. Izvi zvinoita kuti FeCrAl ive yakakosha munzvimbo dzine zvinokwanisa kuita corrosion elements.
4.Electric Resistivity
Nichrome kazhinji ine yakakwirira yemagetsi resistivity kupfuura FeCrAl, zvinoreva:
- Nichrome inogona kuburitsa kupisa kwakawanda nehuwandu hwakafanana hwezvino
- FeCrAl inogona kuda zvishoma zvazvino zvekudziya kwakaenzana
Zvisinei, FeCrAl's resistivity inowedzera zvakanyanya nekushisa, izvo zvinogona kubatsira kune mamwe maitiro ekutonga.
5.Mechanical Properties uye Formability
Nichrome inowanzoita ductile uye iri nyore kushanda nayo patembiricha yekamuri, zvichiita kuti zvive zvakanaka kune maapplication anoda maumbirwo akaomarara kana mabhendi akaomarara. FeCrAl inova yakawanda ductile kana ichipisa, izvo zvinogona kubatsira panguva yekugadzira maitiro asi zvingada yakakosha kubata pakamuri tembiricha.
6.Cost Kufunga
FeCrAl alloys anowanzo kudhura zvishoma pane Nichrome nekuti anotsiva anodhuranickelnesimbi. Iyi mutengo mukana, yakasanganiswa neyepamusoro-tembiricha kuita, inoita FeCrAl sarudzo inokwezva kune akawanda maindasitiri maapplication.
Sei Kusarudza Yedu FeCrAl Zvigadzirwa?
Yedu FeCrAl yekudziya zvinhu inopa:
- Yepamusoro-yepamusoro tembiricha kuita (kusvika 1400 ° C)
- Yakanakisa oxidation uye corrosion kuramba
- Hupenyu hurefu hwebasa mumamiriro akanyanya
-Inodhura-inoshanda imwe kune nickel-based alloys
-Customizable mhinduro kune yako chaiyo application zvaunoda
Kunyangwe iwe uri kugadzira mafirita emaindasitiri, masisitimu ekudziya, kana midziyo yakakosha, zvigadzirwa zvedu zveFeCrAl zvinopa kusimba uye kuita kunodiwa kune nharaunda dzinoda.Taura nesunhasi kuti tikurukure kuti mhinduro dzedu dzeFeCrAl dzinogona sei kusangana nezvinodiwa zvako zvekudziya uku uchikwirisa mitengo yako yekushandisa.
