摘要:
针对电子产品对高耐蚀、深冲成形的加工使用需求，基于CSP短流程工艺开发了热镀锌深冲IF钢DC53D+Z-E。通过对深冲IF钢化学成分及冶炼工艺进行优化研究，并结合热轧高温终轧(900～940 ℃)、高温卷取(710～750 ℃)工艺，以及75%～85%冷轧压下率与830 ℃连续退火，成功制备出电子产品用热镀锌IF钢DC53D+Z-E。中性盐雾测试显示，镀层重量为80 g/m2的DC53D+Z-E钢板在377 h出现红锈，耐腐蚀性能良好。测试显示，DC53D+Z-E钢板屈服强度为150～180 MPa，延伸率为40%～48%，塑性应变比为2.3～3.5，满足手机中框、笔记本电脑键盘、电磁屏蔽罩等精密部件的加工使用要求。研究成果为CSP短流程生产电子产品用热镀锌深冲IF钢提供了技术方案。
Abstract:
Aiming at the processing and use requirements of electronic products for high corrosion resistance and deep drawing forming, DC53D+Z-E steel was developed based on CSP short process. By optimizing the chemical composition and smelting process of deep drawing IF steel, combined with hot rolling high temperature finish rolling (900~940 °C), high temperature coiling (710~750 °C) process, 75%~85% cold rolling reduction rate and 830 °C continuous annealing, hot-dip galvanized IF steel DC53D+Z-E for electronic products was successfully prepared. The tests show that the DC53D+Z-E steel plates with a coating weight of 80 g/m2 appear red rust after 377 h, indicating excellent corrosion resistance. The mechanical properties test shows that the yield strength of DC53D+Z-E steel plate is 150~180 MPa, the elongation is 40%~48%, and the plastic strain ratio is 2.3~3.5, which meets the processing requirements of precision parts such as mobile phone middle frame, notebook computer keyboard and electromagnetic shielding cover. This study provides a technical solution for the production of hot-dip galvanized deep-drawing IF steel for electronic products by CSP short process.
