孔凡庆, 程晓杰, 贾松, et al. Development of Chromium-Free Passivating and Finger-Mark Proofing Hot-Dip Zinc-Coated Steel Sheet[J]. Special Steel, 2014, 35(3): 33-35.DOI:
According to the quality issues including finger-mark proofing firm thickness un-uniform
roll marks sensitiveness to form marks etc. in production of chromium-free passivating and finger-mark proofing cold-rolled 0. 3 〜2. 5 mm sheet of DX15D +Z plain carbon steel at Shougang Cold Rolling Sheet Co
the process control measures such as stop of reverse coating of chemical coating machine
control of finger-mark proofing firm thickness of sheet and passivated roll marks etc. are put forward. Production results show that the sheet products salt spray corrosion resistance for 96 h
the surface electric resistance and the baking varnish adhesive etc. properties all meet the requirement.
