摘要

针对首钢冷轧薄板公司冷轧的0.3~2.5 mm无铬钝化耐指纹DX15D+Z普通低碳钢薄板生产过程出现的耐指纹膜厚度不均

辊印敏感形成印痕等质量问题

提出化学涂机逆涂报停、耐指纹膜厚控制、钝化辊印等工艺控制措施。生产结果表明

薄板成品96 h盐雾耐蚀性

表面电阻试验

烤漆附着力等性能均满足要求。

Abstract

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.
