Qhov loj me:
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.
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
