FeCrAl 0Cr21Al6Nb Tsis kam cua sov hlau rau kev lag luam cua sov khoom
Kev piav qhia txog khoom
FeCrAl 0Cr21Al6Nb Resistance Heating Wire yog ib qho hlau chromium aluminium alloy uas ua tau zoo heev rau kev siv hluav taws xob hauv kev lag luam uas xav tau kev tiv thaiv oxidation zoo heev thiab kev ua haujlwm ntev ntawm qhov kub siab.
Cov hlau no muaj cov chromium, txhuas thiab niobium, tsim ib txheej alumina tiv thaiv thaum lub sijhawm ua haujlwm kub siab. Cov txheej oxide no txhim kho kev tiv thaiv oxidation thiab ntev lub neej ua haujlwm ntawm cov khoom cua sov.
Nrog rau kev tiv thaiv hluav taws xob ruaj khov thiab kev tiv thaiv cua sov zoo heev, 0Cr21Al6Nb FeCrAl hlau yog siv dav rau kev tsim cov khoom siv cua sov rau lub cub tawg, cov cua sov hluav taws xob, cov kilns thiab cov khoom siv ua thermal.
Kev Tshuaj Xyuas Nominal
21.00 Cr, 6.00 Al, Bal. Fe
Qhov kub ua haujlwm siab tshaj plaws: 1350ºC.
Kub yaj: 1500ºC
Fais fab Resistivity: 1.45 micro ohm / m
Tau siv dav dav ua cov khoom siv cua sov hauv cov cub tawg thiab cov cub hluav taws xob.
Muaj lub zog kub tsawg dua li Tophet alloys tab sis qhov kub siab dua.
