Intshayelelo kwi-Heating Alloys
Xa ukhetha izinto zokufudumeza, kukho iintlobo ezimbini ze-alloys ezihlala ziqwalaselwa:I-Nichrome(I-Nickel-Chromium) kunyeI-FeCrAl(Iron-Chromium-Aluminium). Nangona zombini zisebenza ngeenjongo ezifanayo kwizicelo zokufudumeza ezithintela ubushushu, zineempawu ezahlukeneyo ezenza zilungele iimeko ezahlukeneyo kunye nezicelo. Ukuqonda la mahluko kubalulekile ekukhetheni izixhobo ezifanelekileyo kwiimfuno zakho ezithile.
1. Ulwakhiwo kunye neempawu ezisisiseko
I-Nichrome yi-alloy ye-nickel-chromium edla ngokuba ne-80% ye-nickel kunye ne-20% ye-chromium, nangona kukho ezinye ii-ratios. Olu dibaniso lubonelela ngokumelana okuhle ne-oxidation kwaye lugcina amandla kumaqondo obushushu aphezulu. Ii-alloys ze-Nichrome zaziwa ngokuma kwazo kunye nokusebenza kwazo rhoqo kuluhlu olubanzi lwamaqondo obushushu.
Ii-alloys zeFeCrAl, njengoko igama lisitsho, zenziwe ngokuyintloko ngentsimbi (Fe) kunye nokongezwa okubalulekileyo kwe-chromium (Cr) kunye ne-aluminium (Al). Umxube oqhelekileyo unokuba yi-72% yentsimbi, i-22% ye-chromium, kunye ne-6% ye-aluminium. Umxholo we-aluminium ngokukodwa uphucula ukusebenza kwe-alloy kubushushu obuphezulu kunye nokumelana ne-oxidation.
2. Ukusebenza kobushushu
Omnye umahluko obalulekileyo ukho kumaqondo obushushu aphezulu okusebenza:
- I-Nichrome idla ngokusebenza ukuya kuthi ga kwi-1200°C (2192°F)
- I-FeCrAl inokumelana namaqondo obushushu afikelela kwi-1400°C (2552°F)
Oku kwenza i-FeCrAl ibe yeyona ilungileyo kwizicelo ezifuna ubushushu obugqithisileyo, ezifana nezitofu zoshishino okanye izixhobo zelebhu ezishushu kakhulu.
3. Ukumelana ne-Oxidation
Zombini ii-alloys zenza iileya ze-oxide ezikhuselayo, kodwa ngeendlela ezahlukeneyo:
- I-Nichrome yenza umaleko we-chromium oxide
- I-FeCrAl iphuhlisa umaleko we-aluminium oxide (alumina)
Umaleko we-alumina kwi-FeCrAl uzinzile ngakumbi kumaqondo obushushu aphezulu kakhulu, nto leyo enika ukhuseleko olungcono lwexesha elide kwi-oxidation kunye ne-corrosion. Oku kwenza i-FeCrAl ibe luncedo ngakumbi kwiindawo ezinezinto ezinokubangela i-corrosion.
4. Ukumelana nombane
I-Nichrome ngokubanzi ine-resistivity ephezulu yombane kune-FeCrAl, oko kuthetha ukuba:
- I-Nichrome inokuvelisa ubushushu obuninzi ngomlinganiselo ofanayo wamandla ombane
- I-FeCrAl ingadinga amandla ombane angaphezulu kancinci ukuze kufudunyezwe ngokulinganayo
Nangona kunjalo, ukumelana kwe-FeCrAl kuyanda kakhulu xa kujongwa ubushushu, nto leyo enokuba luncedo kwezinye iinkqubo zolawulo.
5. Iipropati zoomatshini kunye nokubumbeka kwazo
I-Nichrome ngokubanzi ithambile ngakumbi kwaye kulula ukuyisebenzisa kubushushu begumbi, nto leyo eyenza ukuba ikhetheke kwiimfuno ezifuna iimilo ezintsonkothileyo okanye ukugoba okuqinileyo. I-FeCrAl iba thambile ngakumbi xa ishushu, nto leyo enokuba luncedo ngexesha leenkqubo zokwenziwa kodwa inokufuna ukuphathwa okukhethekileyo kubushushu begumbi.
6. Izinto eziqwalaselwayo ngeendleko
Ii-alloys zeFeCrAl zihlala zibiza kancinci kuneNichrome kuba zithatha indawo yexabiso eliphantsii-nickelngentsimbi. Le nzuzo yexabiso, xa idibene nokusebenza okuphezulu kobushushu, yenza iFeCrAl ibe lukhetho olunomtsalane kwiintlobo ngeentlobo zezicelo zoshishino.
Kutheni Ukhetha Iimveliso Zethu zeFeCrAl?
Izinto zethu zokufudumeza zeFeCrAl zibonelela ngezi zinto zilandelayo:
- Ukusebenza kakuhle kakhulu kumaqondo obushushu aphezulu (ukuya kuthi ga kwi-1400°C)
- Ukumelana kakuhle kwe-oxidation kunye nokugqwala
- Ubomi benkonzo obude kwiimeko ezinzima kakhulu
- Enye indlela engabizi kakhulu kune-alloys esekelwe kwi-nickel
- Izisombululo ezenziwe ngokwezifiso kwiimfuno zakho zesicelo esithile
Nokuba uyila ii-oven zoshishino, iinkqubo zokufudumeza, okanye izixhobo ezikhethekileyo, iimveliso zethu ze-FeCrAl zibonelela ngokuqina nokusebenza okufunekayo kwiimeko ezifuna amandla.Qhagamshelana nathinamhlanje ukuze sixoxe ngendlela izisombululo zethu zeFeCrAl ezinokuhlangabezana ngayo neemfuno zakho zezinto zokufudumeza ngelixa ziphucula iindleko zakho zokusebenza.
