Title: Control for hot-rolling strip mill - with feed-forward and continuous correction of process parameters e.g. roll setting
Inventor: GLEISSNER GERHARD
IPC: B21B37/52
Filed: 1991-09-24
Abstract: Torque, rotational speed and the rolling force are measured at the first stand, and then at subsequent stands to establish an instantaneous process parameter e.g. roll setting, for the strip. The established parameter is fed forward to each subsequent stand, and is continuously checked and improved by reaction measurements during passage of the strip. Pref., the first and subsequent stands serve as trip thickness measuring stands for the subsequent stands and the measurement values are used to control the setting of the subsequent stands. The thickness variations are obtd. via the hydraulic setting cylinders to eliminate the influence of roll eccentricities. USE/ADVANTAGE - Used in the metal rolling industry. In comparison with the traditional control methods involving loop lifting mechanisms, it is less complicated mechanically, and it is not limited by inertia to relatively low rolling speeds.
