Yuav ua li cas kuaj zinc txheej thickness ntawm DX51D + Z steel coils?
A: Feem ntau siv txoj hauv kev suav nrog fluorescent X- kuaj kab hluav taws xob (tsis yog- kuaj kev puas tsuaj) thiab kev ntsuas gravimetric. Txoj kev gravimetric yuav tsum tau tshem cov zinc txheej nrog hydrochloric acid, xam cov zinc txheej hnyav raws li qhov sib txawv ntawm qhov hnyav ua ntej thiab tom qab tshem tawm, thiab tom qab ntawd hloov qhov no mus rau qhov tuab, ua raws li cov cai ntawm GB / T 1839-2008 tus qauv.
Dab tsi yog cov yam ntxwv ntawm cov khoom siv substrate ntawm DX51D + Z steel coils?
A: Lub substrate feem ntau yog tsawg-carbon aluminium-tua steel nrog cov ntsiab lus carbon tsawg, muaj cov khoom zoo stamping thiab dabtsi yog khoov tsim, tsim nyog rau kev ua cov khoom siv hauv tsev, kev tsim kho, thiab lwm yam.
Dab tsi yog cov ntawv thov tseem ceeb ntawm DX51D + Z steel coils?
A: Siv dav hauv kev tsim lub ru tsev, phab ntsa, thiab kev txhawb nqa; cua txias sab vaj huam sib luag thiab tshuab ntxhua khaub ncaws qhov rooj vaj huam sib luag hauv cov khoom siv hauv tsev; automotive lub cev qhov chaw thiab chassis Cheebtsam; thiab kuj yog substrate rau xim -coated steel ntawv.
What are the common surface quality grades of DX51D+Z steel coils?
A: Cov qhab nia muaj xws li FB (Flawless Finish). FB qib tso cai rau cov teeb meem me me xws li khawb me ntsis. Cov qib sib txawv sib txawv ntawm qhov sib txawv ntawm qhov tiav thiab tsim nyog rau cov khoom uas muaj qhov txawv txav.
Dab tsi yog vim li cas rau zinc txheej tev tawm DX51D + Z steel coils?
A: Yog vim li cas muaj xws li substrate deg oxidation, paug ntawm qhov txias dov emulsion, tsis tsim nyog annealing rauv cua sov, tsis tshua muaj txhuas cov ntsiab lus nyob rau hauv lub zinc lauj kaub, tsis txaus strip nkag kub, los yog tsis txaus theem txo.
