摘    要：在板带热轧过程中,需要使用短行程控制技术来避免带钢头尾出现明显的鱼尾,改善带钢头尾的平面形状。针对迁钢2160热轧在实际生产中遇到的带钢头尾宽度超差问题,通过分析原控制程序得到其短行程控制模型的设定及在线自适应方法,并通过模型仿真给出各个人工配置参数对神经网络形式曲线形状的影响,并据此来调整人工配置参数和自适应参数。实践表明,采用细化人工配置参数层别和调整在线自适应参数的措施可成功降低带钢头尾宽度与本体宽度的偏差,提高了带钢头尾宽度控制精度。

Abstract: During hot strip rolling process,short stroke control technology is necessary to avoid the fish tail and get rectangular ends.As for the problem of width excess of strip head and tail ends in Qiangang 2160 HSM,the set-up and adaption principles of its SSC model were got by analyzing control program source code,and the influence of each human configuration parameter to the neural network SSC curve was evaluated by emulation,according to which the human configuration parameters and adaption parameters were adjusted in practice.The practice has showed that these measures reduced strip head and tail width deviation effectively.
