Zog tag nrho cov hlau Coils Dub Annealed Nta:
Cov Qauv Qauv: Ntsib GB / T 700-2006 Q235b Yuav Tsum Tau
Cov yam ntxwv xwm txheej xwm txheej xwm txheej: Tsis muaj annealing tom qab dov txias, khaws cov yam ntxwv ua haujlwm tawv
Nto Kho: Black Oxide Zaj Duab Xis (tsis yog pickled, tsis muaj txheej)
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Muaj lub zog muaj zog, cov xim muaj zog
Dub Annealed Crfh cov txheej txheem nta:
Txias Rolling Compression Ratio: 60%-80}% (txiav txim siab qhov kawg hardness)
DA Roughness: Ra 1.2-2.5 μm
Cov Qauv Hlau: Ferrite + Cov Poj Niam (Cov Qauv Deformation (txias)
Residual kev ntxhov siab: Xav tau kev tswj hwm los ntawm cov txheej txheem flattening

Q235 Tag nrho cov tawv tawv CBA coil ua kev tiv thaiv
Nias:
Haum rau kev xuas nrig ntaus yooj yim tsuas yog (aperture ntau dua lossis sib npaug ntawm phaj tuab)
Pom zoo poj niam: 8%-10}}% phaj tuab
Yuav tsum muaj hardness tuag hlau xws li SKD11
Cov txheej txheem vuam:
Pom zoo cov ris tsho tiv thaiv vuam (Mag)
Preheating kub: {100-150℃(thaum phaj tuab> 6mm)
Kev nyuaj siab pab txhawb kev pab txhawb nqa tom qab vuam (xws li 300℃× 1h)
Nto Kho:
Sandblasting yog yuav tsum tau ua ntej phosphating (sa2.5 qib)
Cov neeg pom zoo uas yuav tsum tau muab cov tshuab hluav taws xob ua kom tawg yooj yim zaj duab xis yog 60-80 μm
