1.What yog cov hom tseem ceeb ntawm substrates raws li yob cov txheej txheem?
Txias - rolled steel sawb / Steel Sawb
Nta: Qhov no yog qhov feem ntau siv thiab thawj substrate rau galvanized chev. Nws muaj ib qho chaw nyob ruaj khov, siab qhov tseeb qhov tseeb, thiab cov tuab sib txawv.
Cov Kev Siv: Siv rau hauv feem ntau cov ntawv thov uas xav tau cov khoom zoo nyob hauv lub cev thiab cov khoom siv hluav taws xob siab, thiab cov vaj tse vov tsev.
Kub - rolled steel sawb / Steel Sawb
Nta: Tus nqi them feem ntau qis dua li txias - rolled steel sawb, tab sis cov nplaim hluav taws xob muaj cov nplai thiab qhov chaw qis dua. Thaum siv raws li substrate, nws yog feem ntau pickled kom tshem tawm cov nplai.
Cov ntawv thov: feem ntau siv hauv cov ntawv thov uas muaj zog yog qhov yuav tsum tau tab sis muaj zog me tab sis muaj qee cov kab teeb tsa, cov thawv tsheb, thiab cov thawv ntim. Lo lus "kub {{{{- dip galvanizing"
2.Qhov hom twg muaj raws li cov khoom siv tshuab thiab siv?
Cov Khoom Lag Luam Hlau
Piv Txwv Code: Cq
Nta: Tsawg zog thiab nruab nrab muaj. Feem ntau siv rau kev khoov yooj yim los yog tsim.
Cov ntawv thov: Kev tso cua dav dav, ntim yooj yim, qis {{{{}}}}}}}}}} Ent cov vaj, thiab lwm yam.
Stamping Steel
Piv Txwv: DQ
Nta: Cov qauv zoo, haum rau kev siv pob zeb khov kho thiab sib sau ua ke.
Cov Ntawv Thov: Khoom Siv Vaj Tsev, Kev Siv Tsheb Sab Hauv, thiab lwm yam.
Sib sib sib zog nqus hlau hlau
Piv txwv li code: DDQ
Nta: Kev ua sib sib nqus sib sib nqus tau zoo heev, tiv taus kev tawg thaum ua tiav.
Cov Ntawv Thov: Tsheb tso tsheb hlau luam roj tsheb, tshuab ntxhua khaub ncaws nruas, thiab cov khoom sib sib zog nqus.
3.Qhov dab tsi yog qhov taw qhia tseem ceeb ntawm lub substrate?
Cov Khoom Siv Neeg Kho Tshuab:
Tos lub zog: kev ntxhov siab thaum twg cov khoom pib plastically deform.
Lub zog tensile: qhov kev ntxhov siab tshaj plaws cov khoom siv tuaj yeem tiv taus ua ntej tawg.
Elongation: ib qho kev ntsuas ntawm cov khoom siv cov plasticity; ntau dua qhov tseem ceeb qhia tau zoo dua.
Muaj peev xwm:
Yas strain piv Piv: Kev ntsuas ntawm cov khoom siv tiv thaiv kom thinning. Cov R qhov tseem ceeb tshaj qhia tau zoo dua- kev kos.
Ua Haujlwm Hardening Performance index: Kev ntsuas ntawm cov khoom siv muaj peev xwm nce lub zog thaum lub sijhawm ua. Siab dua n qhov tseem ceeb qhia cov kev sib txawv ntau dua qub thiab muaj txiaj ntsig zoo rau kev tawm dag zog hauv zos.
Zoo Tshaj:
Nto qhov tsis xws nyob rau hauv substrate (xws li khawb, pits, thiab suav nrog) tuaj yeem hloov ncaj qha rau saum galvanized, cuam tshuam cov tsos thiab zoo ntawm cov khoom kawg.
4.What yog lub logic qab cov khoom xaiv?
Cov khoom lag luam zoo tib yam: tus nqi qis, nruab nrab muaj peev xwm; Kev dim pa, cov qauv yooj yim.
Stamping / Sib sib zog nqus cov hlau: muaj kev ruaj khov ua, muaj zog nruab nrab, siv cov khoom hauv tsev, khoom siv hauv vaj tsev sab hauv, siv lub tsev sab hauv av.
5.Qhov cov ntsiab lus tseem ceeb hauv cov khoom xaiv?
Cov khoom siv hauv paus rau galvanized coils tsis yog ib qho, tab sis theej ua tiav tsev neeg ntawm cov ntaub ntawv hlau.
Lub "Galvanizing" tsuas yog ib qho kev tiv thaiv tiv thaiv nyob rau saum npoo, thaum lub hauv paus "thiab" lub zog, muaj peev xwm stamping muaj peev xwm, thiab lwm yam).
When selecting galvanized coils, the desired base material must be determined based on the end product's application (whether it will need to bear weight), processing method (simple bending or deep drawing), and service environment.
