摘要
介绍了热轧双相钢在汽车板"以热代冷"进程中的发展情况、国内外主要热轧双相钢产品的化学成分和性能,及其在车身结构及车轮上的应用情况,同时指出,依托短流程薄规格生产工艺技术优势,进一步提高热轧双相钢的生产稳顺性、组织性能稳定性、成品的板形和表面质量,将是实现汽车结构用低成本热轧双相钢开发生产的重要研发方向。
The development situation of hot-rolled DP steel in "replacing cold rolled automobile sheet products by hot rolled one" and the application of hot-rolled DP steel in vehicle body structure and wheels were intro- duced. The chemical composition and properties of main DP steels produced at home and abroad were de- scribed. According to the performance requirements of high strength steel for automotive structural parts and process characteristics of compact production line, further improving production stability, structure property stability, strip shape and surface quality will become the key direction of research and development of low-cost hot-rolled DP steel for automobile manufacture.
