摘　　要：通过进行控轧和控冷实验,并现场进行跟踪测试,取得大量数据,经技术质量分析,阐明了不同工艺参数对螺纹钢性能的影响,并提出相应的改进措施。实验结果表明:在目前设备条件下,只要控制好化学成分、加热温度、终轧温度及终轧冷却速度,所生产的20MnSiNbⅢ级螺纹钢不仅有显著经济效益而且能够达到标准所要求的性能。A lot of experimental data are collected through controlled roiling and cooling experiment and on-the-spot testing. The property influence of reinforced bar with difference technical parameters is explained based on technical quality analysis and improvement measures are put forward. Its result show that 20MnSiNb Ⅲ class reinforced bar has a great benefits under the condition of present equipment, for example, controlled chemical composition, reheating temperature, fine rolling temperature and fine rolling cooling speed. Meanwhile, property of 20MnSiNb Ⅲ class reinforced bar can meet needs of the standard.
