Inkcazo ngokubanzi
I-alloy ye-FeCrAl yenziwe ngubushushu obuphezulu, i-ferritic iron-chromium-aluminium alloy enokusetyenziswa kumaqondo obushushu ukuya kwi-1350degrees. Usetyenziso oluqhelekileyo lwe0Cr21Al6Nb zinjengombaneinto yokufudumezas kwiziko lobushushu obuphezulu kunyango lobushushu, iiseramikhi, iglasi, intsimbi, kunye namashishini ombane.
Uphawu:
Ngobomi benkonzo ende.Ukufudumala ngokukhawuleza.Ukusebenza kakuhle kwe-thermal.Ubushushu obufanayo. Inokusetyenziswa ngokuthe nkqo. Xa isetyenziswa kwi-voltage elinganisiweyo, akukho nto iguquguqukayo.Lukhuseleko lokusingqongileyo ucingo lokufudumeza kombane. Kwaye enye indlela yocingo lwe-nichrome ebiza kakhulu.Inokwenziwa ngokwezifiso ngokweemfuno zabathengi
Iialloyi ze-FeCrAl ziphawulwa ngokumelana ne-oxidation okugqwesileyo kunye nozinzo oluhle kakhulu olukhokelela kubomi obude.
Ngokuqhelekileyo zisetyenziswa kwizinto zokufudumeza zombane kwiziko loshishino kunye nezixhobo zasekhaya.
I-alloy ye-Fe-Cr-Al ene-resistivity ephezulu kunye nobushushu bokusebenza kunoko kwe-NiCr alloy kwaye inexabiso eliphantsi.
Usetyenziso
0Cr21Al6 Iron-chrome-aluminium resistor strip isetyenziswa ngokubanzi ukwenza izinto zokufudumeza zombane kwizixhobo zasekhaya kunye neziko lemizi-mveliso. Usetyenziso oluqhelekileyo zii-ayini ezisicaba, oomatshini boku-ayina, izifudumezi zamanzi, ukubumba iplastiki kuyafa, iiayini zokudambisa, izinto zetsimbi ezigqunywe nge-tubular kunye nezinto zekhatriji.
indawo yesicelo
Iimveliso zethu zisetyenziswa kakhulu kwizixhobo zonyango lobushushu, iinxalenye zemoto, ukwenziwa kwentsimbi kunye nentsimbi,
ishishini aluminiyam, izixhobo metallurgical, izixhobo petrochemical, oomatshini iglasi, oomatshini ceramic,
oomatshini bokutya, oomatshini bamayeza, kunye noshishino lobunjineli bamandla.
