Qhov loj me ntawm Nickel alloy hlau:

Peb muab cov khoom nyob rau hauv cov duab ntawm cov hlau, tiaj tus hlau, strip.Peb kuj tuaj yeem ua cov khoom siv raws li cov neeg siv khoom thov.

Kaj thiab dawb hlau-0.025mm ~ 3mm

Pickling hlau: 1.8mm ~ 10mm

Oxidized hlau: 0.6mm ~ 10mm

Flat hlau: thickness 0.05mm ~ 1.0mm, dav 0.5mm ~ 5.0mm

Txheej txheem:

Hlau: Cov khoom npaj → melting → re-melting → forging → kub dov → kho cua sov → kev kho deg → kos duab (dov) → tiav kev kho cua sov → tshuaj xyuas → pob → warehouse

Khoom nta ntawm nichrome hlau:

1) Zoo heev los tiv thaiv oxidation thiab txhua yam muaj zog ntawm qhov kub thiab txias;

2) High resistivity thiab qis kub coefficient ntawm kuj;

3) Zoo heev reelability thiab tsim kev ua tau zoo;

4) Zoo heev vuam kev ua tau zoo
