Q: Dab tsi yuav tsum tau txiav txim siab thaum yuav khoom txias -rolled coils?
A: Cov ntsiab lus tseem ceeb: qib khoom, thickness (nrog rau kev kam rau siab), qhov dav, qhov ntev / coil hnyav, qib nto, cov qauv siv tau, cov khoom siv kho tshuab, khoom xa tuaj (annealed / hardened), thiab ntim khoom.
Q: Dab tsi yog qhov kev xa khoom rau txias -rolled coils?
A: Tej yam kev mob:
Annealed (mos): Code M, zoo yas, haum rau stamping;
Hard: Code H, siab zog, haum rau cov yam ntxwv qhov chaw uas tsis xav tau kev sib sau;
Daim tawv nqaij dhau: Code S, daim ntawv zoo, du nto.
Q: Dab tsi yog qhov yuav tsum tau ntim rau txias -rolled coils?
A: Cov txheej txheem ntim khoom: sab hauv hauv ob sab phlu nrog xeb-cov ntaub ntawv pov thawj / yas zaj duab xis, txheej txheej nrog cov hlua khi, kaum tiv thaiv (kom tiv thaiv ntug kev puas tsuaj), thiab lub tes tsho tiv thaiv rau lub kauj coil; rau kev thauj mus los hauv hiav txwv, yuav tsum muaj dej noo-cov ntaub ntawv pov thawj thiab fumigated ntoo pallets (rau kev xa tawm).
Q: Dab tsi yog kev ceev faj rau khaws cia txias -rolled coils? A: ① Khaws rau hauv qhov chaw qhuav, qhov dej zoo - qhov cua nkag rau hauv tsev (cov av noo ≤60%); ② Khaws kom deb ntawm qhov chaw acidic, alkaline, thiab ntsev tsuag; ③ Khaws cov coils vertically kom tsis txhob compression thiab deformation; ④ Tsis tu ncua tshuaj xyuas cov ntim thiab tshem tawm txhua qhov chaw puas tsuaj sai.
Q: Dab tsi cuam tshuam rau tus nqi ntawm cov khoom txias-rolled coils?
A: Cov yam tseem ceeb: raw khoom kub- dov coil nqi, cov nqi ua haujlwm (annealing/leveling), qib/precision, specifications (khoom kim heev rau nyias / nqaim cov ntaub ntawv), kev lag luam thiab kev thov, nqi tsheb thauj mus los, thiab txheej / deg kho.
