2. Cov Txheej Txheem
Muaj meej
Puas yog nws haum rau kev sib sib zog nqus duab, ncab, lossis cov kab khoov? (DC01 yog qeb stamping dav dav; cov ntu nyuaj yuav tsum DC04 / DC06.)
Puas muaj tsawg kawg nkaus khoov radius (piv txwv li, 1t tuab sib haum rau R1mm) ua tau raws li qhov yuav tsum tau ua?
Lo lus nug tseem ceeb:
"Yog tias wrinkles lossis cov kab nrib pleb tshwm sim thaum lub thwj, nws puas yog cov teeb meem khoom lossis pwm?"
Nto Zoo
Puas yog qhov saum npoo ua tiav ntawm cov coil txias kom du, thiab puas muaj qee yam tsis xws li khawb lossis oxidation me ntsis?
Dab tsi yog cov nplaum ntawm zinc txheej ntawm dc 01+}} z galvanized chev (piv txwv li, puas yooj yim tev tawm)?
3. Cov txheej txheem galvanized (piv txwv li, dc 01+ z)
Puas yog zinc txheej hnyav hnyav (piv txwv li, z60, z80) ntsib txoj kev tiv thaiv corrosion corrosion?
Galvanizing hom: Hot-Dip Galvanizing (GI) lossis electroplated galvanizing (piv txwv li)?
Lo lus nug tseem ceeb:
"Rau DC01 galvanized chev rau kev siv sab nraum zoov, yog z60 lossis z120 ntau dua zinc txheej?"
4. Qhov ntev thiab thev taus
Puas yog cov tuab tuab tiv thaiv (xws li, ± 0.05mm) Raws li qhov yuav tsum tau ua?
Puas yog tus coil dav thiab xws li, 508mm lossis 610 hli) sib xws nrog cov kab ntau lawm?
Lo lus nug tseem ceeb:
"Vim li cas cov tuab tuab tuab dua cov nominal tuab? Nws yuav cuam tshuam cov khoom siv?"
5. Cov khoom lag luam zoo
Puas yog qhov kev ua tau zoo sib txawv ntawm cov pob zeb (xws li tensile zog ± 20mpa) tswj tau?
Puas muaj qhov tsis xws luag xws li ntug nrib pleb thiab suav nrog?
Lo lus nug tseem ceeb:
"Los ntawm tib pawg ntawm DC01, qee cov coils tsis yog stamping zoo. Kuv tuaj yeem daws teeb meem li cas?"
6. Tus nqi thiab kev sib cav
Puas muaj qib ntxiv rau lwm tus (piv txwv li, spcc) siv?
Yuav ua li cas thiaj li yuav tsum ua rau cov nqi hauv tsev (piv txwv li, ib-tuj cov nyiaj cheb)?
Lo lus nug tseem ceeb:
"DC01 thiab SPCC muaj kev ua tau zoo sib xws. Lawv puas tuaj yeem sib xyaw?"
7. Cov Qauv thiab Ntawv Pov Thawj
Nws puas ua raws li EN 10130, JIS G 3141 (SPCC), lossis ASTM cov qauv?
Puas muaj kev lag luam automotive kev lag luam ntawv pov thawj (piv txwv li, ITAF 16949)?
8. Cov Kev Xav Tshwj Xeeb
Kev ua Vuam kev ua lag luam: Hlau me muaj kev pheej hmoo weldability, tab sis yuav tsum paub txog kev pheej hmoo ntawm Weld Porosity hauv Zinc Txheej (Galvanized DC01).
Paintability: Puas yog xav tau kev kho mob tshwj xeeb (xws li phosphating) txhawm rau txhim kho cov xim nplaum?
Cov Neeg Siv Cov Lus Nug
"DC01 yog dab tsi yog qhov twg DC04? Kuv yuav xaiv rau kuv ib feem?"
DC01 yog tsim nyog rau yooj yim stamping, thaum DC04 tau ntau dua elongation (rau kev kos duab sib sib zog nqus).
"Kuv ntsuas qhov zinc txheej tuab ntawm DC01 galvanized coils?"
Siv cov hau kev gravimetric (G / M²) lossis x-tshav fluorescence tuab gauges.
"Yog DC01 tawg thaum lub sijhawm stamping ib qho khoom siv lossis cov txheej txheem teeb meem?"
Ua ntej, tshuaj xyuas seb cov ntaub ntawv elongation ua tau raws li cov lus qhia tshwj xeeb, tom qab ntawd kho cov tuag ntshiab lossis lubrication.
Lub ntsiab
Qhov kev txhawj xeeb tseem ceeb ntawm cov neeg siv yog: "Tau DC01 tau raws li kuv cov kev xav tau ntawm tus nqi zoo tshaj?" Thaum xaiv cov ntaub ntawv, nws pom zoo kom qhia meej:
Daim ntawv thov (stamping, khoov, vuam, thiab lwm yam)
Kev xav tau kev ua tau zoo (lub zog, ductility, nto zoo)
Tus nqi them nyiaj (seb cov qib yuav tau txais)
Rau Galvanized DC01, kev saib xyuas ntxiv yuav tsum tau them rau kev tiv thaiv corrosion tiv thaiv thiab cov txheej txheem zinc.
