DX51D + Z steel coil txhais li cas?
A: "DX51D" yog European tus qauv txias- dov qis- carbon steel puag khoom qib, sawv cev rau kev ua haujlwm txias txias thiab lub zog nruab nrab. "+Z" qhia tias kub -dip galvanizing. Yog tias ua tiav nrog cov lej xws li Z100 lossis Z275, nws sawv cev rau zinc txheej hnyav ntawm 100g thiab 275g ib square meter, feem.
Dab tsi yog cov qauv DX51D + Z steel kauj ua raws li?
A: Nws feem ntau ua raws li European tus qauv EN 10346, thaum tseem ua tau raws li cov qauv thoob ntiaj teb xws li ASTM A653. Hauv kev siv hauv tsev, GB / T 2518 specifications rau kub -dip galvanized steel nplooj ntawv thiab strips feem ntau hais txog.
Dab tsi yog qhov kev sib raug zoo ntawm DX51D + Z thiab SGCC qib?
A: Lawv cov khoom zoo sib xws. DX51D + Z sib haum rau European tus qauv, thaum SGCC yog Japanese tus qauv kub-dip galvanized steel qib. Ob leeg yog tsawg-cov pa roj carbon kub- cov khoom siv galvanized thiab feem ntau siv sib hloov hauv cov ntawv thov dav dav.
Dab tsi yog cov kauj ruam tseem ceeb hauv kev tsim khoom ntawm DX51D + Z steel coils?
A: Cov kauj ruam tseem ceeb yog: uncoiling → vuam → pretreatment → annealing rauv cua sov → kub -dip galvanizing hauv zinc da dej → txias → xov → passivation thiab oiling → coiling. Qee cov txheej txheem tuaj yeem hloov kho raws li qhov xav tau ntawm qhov chaw.
Dab tsi yog zinc txheej thickness ntawm DX51D + Z steel coils?
A: Cov txheej txheem zinc txheej hnyav li ntawm 20 mus rau 275 g / m², sib haum rau lub thickness ntawm kwv yees li 3 mus rau 39 μm. Cov kev qhia tshwj xeeb muaj xws li Z80, Z100, thiab Z275, uas tuaj yeem xaiv raws li qhov yuav tsum tau muaj kev tiv thaiv corrosion.
