Covzinc hlautxheej txheem ntau lawm feem ntau suav nrog cov kauj ruam hauv qab no:
Kev xaiv cov khoom siv raw: Kev tsim cov zinc hlau feem ntau yog siv cov khoom zoo uas tsis tshua muaj carbon steel hlau rods ua raw khoom.
Kev kos duab: Cov khoom siv raw yog kos rau hauv cov duab los ntawm kev kos duab. Cov kauj ruam no tuaj yeem txhim kho qhov tseeb ntawm cov hlau hlau, tab sis tus nqi siab thiab kev ua haujlwm tsawg.
Pickling thiab xeb tshem tawm: Yuav kom tshem tawm xeb thiab impurities ntawm qhov chaw, yuav tsum tau kho pickling.
Kub kub annealing: Annealing kev kho mob tuaj yeem txhim kho kev ua tau zoo thiab ductility ntawm cov hlau hlau.
Kub-dip galvanizing: Cov hlau kho hlau yog immersed nyob rau hauv molten zinc rau kub-dip galvanizing. Cov kauj ruam no yog qhov txuas tseem ceeb hauv kev tsim cov zinc hlau thiab tuaj yeem txhim kho corrosion kuj thiab kev pab cuam lub neej ntawm cov hlau hlau.
Txias: Yuav tsum txias txias tom qab galvanizing los xyuas kom meej tias zinc txheej yog ruaj khov rau cov hlau hlau.
