摘要
在热连轧生产线上，以510MPa级钢坯轧制590MPa级汽车大梁钢。结果表明，当终轧温度较低（820～840℃）．卷取温度为610-640℃时，含钒微合金钢取得了较佳的沉淀强化与细晶强化成效，产品综合性能满足工业应用要求。
In hot rolling production line, 510MPa grade-level billet was used to roll 590MPa automobile beam steel. The results show that when the fmal rolling temperature is low, about 820-840℃, and coiling temperature is 610-640℃, the micro-alloyed steel with vanadium can achieve well effect of precipitation strengthening and grain strengthening, and the comprehensive performance of the production can meet industrial application requirements.
