The Synthetic Automatic Gauge Control System of High Precision Cold Rolling Mill
-
摘要: 介紹了在高精度四輥可逆冷軋機中所采用的一種綜合型自動厚度控制方案。為了保證軋機能軋出只有±4μm厚差的高精度帶鋼,采用了全液壓推上、恒輥縫控制和計算機控制的綜合控制系統。闡述了根據引起厚差的不同因素所采取的相應措施,給出了實際軋制的厚差曲線,帶材厚差在±4μm以內。Abstract: 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.
