Intshayelelo kwi-Heating Alloys
Xa ukhetha izinto zokufudumeza, ii-alloys ezimbini zihlala ziqwalaselwa:Nichrome(Nickel-Chromium) kunyeFeCrAl(Iron-Chromium-Aluminiyam). Ngelixa zombini zisebenza ngeenjongo ezifanayo kwizicelo zokufudumeza ezixhathisayo, zineempawu ezahlukileyo ezibenza bafanelekele iindawo ezahlukeneyo kunye nokusetyenziswa. Ukuqonda lo mahluko kubalulekile ekukhetheni imathiriyeli efanelekileyo kwiimfuno zakho ezithile.
1.Ukubunjwa kunye neePropati eziSisiseko
I-Nichrome yi-nickel-chromium alloy ene-80% ye-nickel kunye ne-20% ye-chromium, nangona ezinye iireshion zikhona. Olu luhlu lunika ukuchasana okulungileyo kwi-oxidation kunye nokugcina amandla kumaqondo aphezulu. Ama-alloys e-Nichrome ayaziwa ngokubumba kwawo kunye nokusebenza okungaguqukiyo kuluhlu olubanzi lobushushu.
I-FeCrAl alloys, njengoko igama libonisa, ngokuyinhloko yenziwe ngentsimbi (Fe) kunye nezongezo ezibalulekileyo ze-chromium (Cr) kunye ne-aluminium (Al). Ukwakhiwa okuqhelekileyo kunokuba yi-72% yentsimbi, i-22% yechromium, kunye ne-6% ye-aluminium. Umxholo we-aluminiyam uphakamisa ngokukodwa ukusebenza kwe-alloy yobushushu obuphezulu kunye nokumelana ne-oxidation.
2.Ubushushu bokusebenza
Omnye owona mahluko ubalulekileyo ulele kubushushu bawo obuphezulu bokusebenza:
- I-Nichrome isebenza ngokumalunga ne-1200 ° C (2192 ° F)
-I-FeCrAl inokumelana namaqondo obushushu ukuya kuthi ga kwi-1400°C (2552°F)
Oku kwenza i-FeCrAl ibe yeyongamileyo kwizicelo ezifuna ukushisa okugqithisileyo, okufana neziko lamashishini okanye izixhobo zelabhoratri ezinobushushu obuphezulu.
3.I-Oxidation Resistance
Zombini ii-alloys zenza umaleko we-oxide okhuselayo, kodwa ngeendlela ezahlukeneyo:
- I-Nichrome yenza umaleko wechromium oxide
- I-FeCrAl iphuhlisa umaleko we-aluminium oxide (i-alumina).
I-alumina layer kwi-FeCrAl izinzile ngakumbi kumaqondo obushushu aphezulu kakhulu, inika ukhuseleko olungcono lwexesha elide ngokuchasene ne-oxidation kunye nokugqwala. Oku kwenza ukuba i-FeCrAl ixabiseke ngokukodwa kwindawo enezinto ezinokuthi zibe ngumhlwa.
4.Ukunyangwa koMbane
I-Nichrome ngokubanzi inokumelana nombane okuphezulu kune-FeCrAl, okuthetha ukuthi:
- I-Nichrome inokuvelisa ubushushu obuninzi kunye nomlinganiselo ofanayo wangoku
-I-FeCrAl inokufuna umsinga othe kratya wokufudumeza okulinganayo
Nangona kunjalo, ukuxhathisa kwe-FeCrAl konyuka kakhulu ngobushushu, obunokuba luncedo kwizicelo ezithile zolawulo.
5.IiPropati zoomatshini kunye nokuQuquleka
I-Nichrome idla ngokuba yi-ductile kwaye kulula ukusebenza nayo kwiqondo lobushushu begumbi, iyenza ikhetheke kwizicelo ezifuna iimilo ezintsonkothileyo okanye ukugoba okuqinileyo. I-FeCrAl iba yi-ductile ngakumbi xa ishushu, enokuba luncedo ngexesha leenkqubo zokuvelisa kodwa inokufuna ukuphathwa okukhethekileyo kwiqondo lokushisa.
6.Ukuqwalaselwa kweendleko
Iialloyi ze-FeCrAl zihlala zibiza ngaphantsi kwe-Nichrome kuba zithatha indawo ezibizayonickelngentsimbi. Le nzuzo yeendleko, idityaniswe nokusebenza okuphezulu kobushushu obuphezulu, yenza i-FeCrAl ibe lukhetho olunomtsalane kwizicelo ezininzi zamashishini.
