在对比冷轧深冲钢的基础上 ,分析了工业试制的热轧深冲钢板的组织和性能。研究结果表明 :该钢的碳含量较低 ,相应的金相组织和晶粒度合适 ;厚度大于 2 mm的钢板未经冷轧和退火处理可达到与冷轧深冲钢板相当的成型性能 ,是代替冷轧深冲钢板冲压汽车零件的理想材料。该钢生产工艺简单 ,质量稳定 ,具有明显的经济效益和社会效益。 Based on the comparison of cold-rolled deep-drawn steel, the microstructure and properties of hot-rolled deep-drawn steel plate prepared by industrial trial were analyzed. The results show that: the carbon content of the steel is low, the corresponding metallurgical structure and grain size is appropriate; thickness of more than 2 mm of steel without cold-rolled and annealed to achieve the same cold forming and deep drawing steel forming performance is Replaces the ideal material for cold rolling deep drawing steel stamping automotive parts. The steel production process is simple, stable quality, with significant economic and social benefits.
