摘　　要：在包钢CSP生产线上,采用低C-Mn钢成分设计,以控轧控冷工艺批量生产了7000余吨540MPa热轧双相钢。该产品厚度3.5～13mm,组织为铁素体+马氏体,分别用于轿车车轮、重型卡车车轮的轮辐及汽车大梁等,其使用性能良好,能满足汽车车轮的减重要求。More than 7000t 540MPa grade dual - phase hot rolled strips designed with low C - Mn were produced using the control rolling and cooling process in Baotou CSP line. The thickness of the dual- phase strips was 3.5 -13mm with the microstructures of ferrite ＋ martensite, which were applied to manufacture the wheel disk of the car, heave -duty truck and beam. Good formability of the steel was obtained, and the requirement of reducing wheel weight was met.
