Isingeniso kuma-Heating Alloys
Lapho ukhetha izinto zokushisa, kucatshangwa kaningi izinhlobo ezimbili ze-alloys:I-Nichrome(i-Nickel-Chromium) kanyeI-FeCrAl(I-Iron-Chromium-Aluminium). Nakuba zombili zisebenza ngezinjongo ezifanayo ekusetshenzisweni kokushisa okuvimbelayo, zinezici ezihlukile ezenza zifanelekele izindawo ezahlukene kanye nezinhlelo zokusebenza. Ukuqonda lokhu kungafani kubalulekile ekukhetheni izinto ezifanele izidingo zakho ezithile.
1. Ukwakheka kanye nezakhiwo eziyisisekelo
I-Nichrome iyi-alloy ye-nickel-chromium evame ukuqukethe i-nickel engu-80% kanye ne-chromium engu-20%, yize kukhona ezinye izilinganiso. Le nhlanganisela inikeza ukumelana okuhle ne-oxidation futhi igcina amandla emazingeni okushisa aphezulu. Ama-alloy e-Nichrome aziwa ngokwakheka kwawo kanye nokusebenza kwawo njalo ebangeni elibanzi lokushisa.
Ama-alloy e-FeCrAl, njengoba negama lisho, akhiwe ngokuyinhloko ngensimbi (Fe) enezengezo ezibalulekile ze-chromium (Cr) kanye ne-aluminium (Al). Ukwakheka okuvamile kungaba yi-72% yensimbi, i-22% ye-chromium, kanye ne-6% ye-aluminium. Okuqukethwe kwe-aluminium kuthuthukisa kakhulu ukusebenza kwe-alloy ekushiseni okuphezulu kanye nokumelana ne-oxidation.
2. Ukusebenza Kwezinga Lokushisa
Omunye wemehluko obaluleke kakhulu usemazingeni okushisa aphezulu okusebenza kwawo:
- I-Nichrome ivame ukusebenza cishe ku-1200°C (2192°F)
- I-FeCrAl ingamelana namazinga okushisa afinyelela ku-1400°C (2552°F)
Lokhu kwenza i-FeCrAl ibe ngcono kakhulu ezisetshenziswayo ezidinga ukushisa okukhulu, njengezitofu zezimboni noma imishini yelabhorethri eshisa kakhulu.
3. Ukumelana ne-Oxidation
Zombili lezi zinhlobo zakha izendlalelo ze-oxide ezivikelayo, kodwa ngezindlela ezahlukene:
- I-Nichrome yakha ungqimba lwe-chromium oxide
- I-FeCrAl ithuthukisa ungqimba lwe-aluminium oxide (alumina)
Ingqimba ye-alumina ku-FeCrAl izinzile kakhulu emazingeni okushisa aphezulu kakhulu, ihlinzeka ngokuvikelwa okungcono kwesikhathi eside ngokumelene nokugqwala nokugqwala. Lokhu kwenza i-FeCrAl ibe yigugu kakhulu ezindaweni ezinezinto ezingaba yingozi.
4. Ukumelana Nogesi
I-Nichrome ngokuvamile inokumelana okuphezulu kukagesi kune-FeCrAl, okusho ukuthi:
- I-Nichrome ingakhiqiza ukushisa okwengeziwe ngenani elifanayo lamandla kagesi
- I-FeCrAl ingadinga amandla kagesi angaphezulu kancane ukuze kufudunyezwe ngokulinganayo
Kodwa-ke, ukumelana kwe-FeCrAl kuyanda kakhulu ngokushisa, okungaba yinzuzo kwezinye izinhlelo zokusebenza zokulawula.
5. Izakhiwo Zomshini Nokwakheka Kwazo
I-Nichrome ngokuvamile ithambile kakhulu futhi kulula ukuyisebenzisa ekushiseni kwegumbi, okwenza kube ngcono kakhulu ekusetshenzisweni okudinga izimo eziyinkimbinkimbi noma ukugoba okuqinile. I-FeCrAl iba ithambile kakhulu uma ishiswa, okungaba wusizo ngesikhathi sezinqubo zokukhiqiza kodwa kungadinga ukuphathwa okukhethekile ekushiseni kwegumbi.
6. Izindleko Zokucatshangelwa
Ama-alloy e-FeCrAl ngokuvamile abiza kancane kune-Nichrome ngoba athatha indawo yezindleko ezibizayoi-nickelngensimbi. Le nzuzo yezindleko, kuhlanganiswe nokusebenza okuphezulu kokushisa okuphezulu, kwenza i-FeCrAl ibe ukukhetha okukhangayo kwezicelo eziningi zezimboni.
Kungani Kufanele Ukhethe Imikhiqizo Yethu Ye-FeCrAl?
Izinto zethu zokushisa ze-FeCrAl zinikeza:
- Ukusebenza okuphezulu kakhulu ekushiseni okuphezulu (kufika ku-1400°C)
- Ukumelana okuhle kakhulu nokugqwala kanye ne-oxidation
- Impilo yesevisi ende ezimweni ezimbi kakhulu
- Enye indlela engabizi kakhulu kune-alloys esekelwe ku-nickel
- Izixazululo ezenziwe ngezifiso zezidingo zakho ezithile zohlelo lokusebenza
Kungakhathaliseki ukuthi uklama izitofu zezimboni, izinhlelo zokushisa, noma imishini ekhethekile, imikhiqizo yethu ye-FeCrAl inikeza ukuqina nokusebenza okudingekayo ezindaweni ezidinga amandla amaningi.Xhumana nathinamuhla ukuze sixoxe ngendlela izixazululo zethu ze-FeCrAl ezingahlangabezana ngayo nezidingo zakho ze-element yokushisa ngenkathi kuthuthukiswa izindleko zakho zokusebenza.
