Q: Dab tsi yog cov tseem ceeb ntawm kub-dip galvanized coils?
A: ultra-siab lub zog thiab lub teeb ci ntsa iab compatibility
Zoo heev corrosion
Txhim kho cov pwm thiab cov khoom zoo
Kev tiv thaiv ib puag ncig thiab cov txheej txheem hloov tau
Q: Qhov twg yog qhov zoo heev corrosion tsis kam ntawm kub-dip galvanized chev?
A: Metallurgical Kev Ua Haujlwm Ntawm Cov Txheej:
During the hot forming process, the galvanized layer diffuses with the steel substrate to form a zinc-iron alloy layer (Fe-Zn alloy, containing about 10%-11% Fe), and the coating adhesion is significantly better than that of ordinary hot-dip galvanized steel sheets. Salt spray tests show that the red rust resistance of double-sided 10μm zinc-iron alloy Cov txheej tuaj yeem ncav cuag ntau dua 800 teev, uas yog 1.}} 6 lub sij hawm ntawm cov kub dip-dip galvanizing (500 teev).
Corrosion Qhov cuab lub zog ntawm vuam Cheeb Tsam:
Thaum lub sij hawm kub stamping, cov oxide txheej tsim nyob ze ntawm Weld vim muaj kev kub ntxhov los ntawm cov khoom siv hluav taws xob ua kom pom tseeb (xws li cov cua sov
Q: Dab tsi yog qhov tsis zoo ntawm cov kub-dip galvanized coils?
A: Cov khoom siv siab thiab cov nqi ntau lawm
Txoj kev nqaim qhov rai, siab seem
Teeb meem hauv kev ua tiav tom ntej
Hydrogen embrittlement txoj kev pheej hmoo thiab kev sib tw sib tw
Q: Vim li cas thiaj yog tus nqi ntawm kub-dip Galvanized coils siab?
A: nruj kev tswj qhov kub:
Lub cua sov kub ntawm cov hlau phaj yuav tsum tau ua kom pom tseeb hauv thaj tsam ± 5 yog tias nws qis dua 880 degree, nws yuav ua rau tsis muaj kev cuam tshuam tsis txaus; Yog tias nws siab dua li 920 degree, nws yog ib qho yooj yim los tsim cov coarse nplej thiab txo qis kom tsawg dua li 3% los ntawm kev ntsuas kub tshaj plaws ntawm lub voj voog kub.
Cov pwm nrawm:
Thaum lub sij hawm kub stamping, cov pwm ua si kub ntau zaus hloov kho ib zaug (xws li H13} txog 20% .
Q: Vim li cas cov kev ua tom ntej ntawm cov kub-dip galvanized coils nyuaj?
A: Tsis muaj ib tsab ntawv nyeem qib ob:
Tom qab sib sau kub, lub hardness ntawm cov hlau phaj ncav tau ntau tshaj 45}}
Ntau vuam kev txwv:
Thaum vuam nrog cov phiaj hlau zoo tib yam, Laser Vuam lossis CMT CARD txheej txheem nyob ze ntawm cov qauv weld poob los ntawm 8 lab yuan .
