一、前言 在轧机上采用厚度自动控制(AGC)的目的是为了使钢板在轧制方向上厚度均匀,改善产品质量,提高板材收得率。这种控制装置在薄板轧机上使用的时间较长,而在中厚板轧机上采用它还只是最近几年的事。近几年来中厚板的轧制技术随着计算机控制技术的发展也迅速发展起来,而提高钢板的尺寸精度和成品率也成为研究的重点课题,所以出现了几种不同类型的厚度自动控制装置。
I. INTRODUCTION The purpose of automatic thickness control (AGC) on rolling mills is to make the thickness of the steel plate uniform in the rolling direction, to improve the product quality and to increase the yield of the steel plate. This type of control has been used for a long time in sheet mills, and it has only been the case in recent years for plate mills. In recent years, plate rolling technology with the rapid development of computer control technology, and improve the dimensional accuracy and yield of steel has also become the focus of research, so there have been several different types of automatic thickness control device .
