Qhov loj me:
Peb muab cov khoom nyob rau hauv cov duab ntawm cov hlau, tiaj tus hlau, strip.We tuaj yeem txhawb customization;
Bright, annealed, mos hlau-0.025mm ~ 5mm
Acid pickeling dawb 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:
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
