Cov hlau 875Sib Nqus Sib Nqus Fecral Hlau Zoo Daim Ntawv Ruaj Ntseg Rau Precision Resistor
 
Kev Piav Qhia Dav Dav

Cov xov hlau Fe-Cr-Al yog ua los ntawm cov hlau chromium txhuas puag alloys uas muaj cov khoom me me xws li yttrium thiab zirconium thiab tsim los ntawm kev smelting, steel dov, forging, annealing, kos duab, kev kho qhov chaw, kev tswj kev tiv thaiv, thiab lwm yam.
Cov ntsiab lus txhuas siab, ua ke nrog cov ntsiab lus chromium siab cia qhov kub thiab txias tuaj yeem ncav cuag 1425ºC (2600ºF);
Cov hlau Fe-Cr-Al tau tsim los ntawm lub tshuab ua kom txias ceev ceev uas lub zog tswj hwm los ntawm lub khoos phis tawj, lawv muaj nyob rau hauv cov hlau thiab cov ribbon (strip).

FeCrAl Electrictrical Resistance Cov hlau ua kom sov nrog cov hluav taws xob resistivity siab, qhov kub thiab txias coefficient ntawm kev tsis kam yog me me, qhov kub ua haujlwm siab. zoo corrosion tsis kam nyob rau hauv qhov kub siab, thiab tshwj xeeb tshaj yog tsim rau siv hauv cov roj uas muaj sulfur thiab sulfides, tus nqi qis, nws yog dav siv hauv kev lag luam hluav taws xob cub tawg, khoom siv hauv tsev, deb infrared ntaus ntawv zoo tagnrho cua sov khoom.
FeCrAl hom: 1Cr13AI4, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb, 0Cr27AI7Mo2 thiab lwm yam. Series hluav taws xob tiaj tus siv, hluav taws xob hluav taws xob

Daim Ntawv Thov
Peb cov khoom (FeCrAl) cov khoom siv hluav taws xob kub siab muaj peev xwm muag tau thiab siv dav rau kev ua cov khoom siv cua sov xws li lub cub tawg muaj kev lag luam, cov khoom siv cua sov pej xeem, ntau yam hluav taws xob resistors thiab locomotive braking resistor, cov khoom siv infrared, cov roj liquefied infrared heat-resisting net, ntau hom igniting thiab radiating electrodes thiab voltage-regulating resistors rau motors thiab lwm yam hauv Metallurgical machinery, kev kho mob, tshuaj lom neeg, ceramics, electronics, hluav taws xob khoom siv, iav thiab lwm yam kev lag luam pej xeem lossis kev lag luam.

Muaj lwm qhov ntau thiab tsawg rau kev thov.

Cov hlau hluav taws xob tiv taus cua sov muaj cov khoom tiv thaiv antioxidant muaj zog, tab sis ntau yam roj hauv cov cub tawg xws li huab cua, carbon, sulfur, hydrogen thiab nitrogen tseem muaj qee qhov cuam tshuam rau nws.

Txawm hais tias cov xov hlau cua sov no tau muaj kev kho mob antioxidant, kev thauj mus los, kev sib txuas, kev teeb tsa thiab lwm yam txheej txheem yuav ua rau puas tsuaj rau qee qhov thiab txo nws lub neej kev pabcuam.

Yuav kom txuas lub neej ua haujlwm ntev dua, cov neeg siv khoom yuav tsum tau ua kev kho mob ua ntej oxidation ua ntej siv. Txoj kev yog cua sov cov khoom sib xyaw uas tau teeb tsa tag nrho hauv huab cua qhuav kom txog qhov kub (qis dua 100-200C dua li qhov kub siab tshaj plaws), khaws cia cua sov rau 5 txog 10 teev, tom qab ntawd txias qeeb nrog lub cub tawg.
