An experimental prototype of 400 mm silicon steel hot rolling mill was developed by Xi'an Heavy Machinery Research Institue for Wu Gang. The technological parameters, configuration and characteristic of advanced control system in the experimental prototype are introduced in detail. The experimental prototype was realized the fast rolling of 2. 5 m/s in the range of specified rolling temperature. Its automatic rolling control system can acquisite the signals that a rolled piece enters in and exits from the rollers on time. The successful development of the experimental prototype has a profound significance for development of new silicon steel products and research of new technologies.%西安重型机械研究所为武钢开发了目前国内第一台自动化水平较高的先进可靠的硅钢热轧试验轧机.本文介绍了该轧机的工艺参数、设备组成,技术特点及轧制流程,该轧机在规定的终轧温度范围内,实现了2.5 m/s的快速轧制速度,保证了控制系统准确及时的采集到轧件进出轧辊时的信号,缩短道次间隙时间,实现了自动控制,保证了产品板形及精度的高水平要求,对于硅钢尤其是对其取向硅钢新产品、新工艺的开发具有深远意义.
