高精度冷轧机的综合型自动厚度控制系统

The Synthetic Automatic Gauge Control System of High Precision Cold Rolling Mill

介绍了在高精度四辊可逆冷轧机中所采用的一种综合型自动厚度控制方案。为了保证轧机能轧出只有±4μm厚差的高精度带钢,采用了全液压推上、恒辊缝控制和计算机控制的综合控制系统。阐述了根据引起厚差的不同因素所采取的相应措施,给出了实际轧制的厚差曲线,带材厚差在±4μm以内。

In order to ensure that the rolling mill can produce high precision sheet strip with ±4μm thickness tolerence, the advanced control idea and method of all hydraulic push-up, censiant roll gap contrcol and computer synthesis are applied. The measures to take according to the various factors that cause thickness tolerence are discribed. At last, the curve of thickness tolerence in practical rolling process is given.
