Mill rolls are driven by large several thousand horsepower motors. Rolling mills are computer controlled with complex automated drive systems. Overall, rolling mill equipment is expensive and can take a long time to repair or replace, even when slight damage occurs. Types of mills include blooming, bar, rod, plate and strip mills.
In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for the strip exit thickness while PD controller is ...

The tuning, going up in fourth intervals, is the opposite of fiddle/mandolin tuning, which goes (4th to 1st) downward in fourths, or upward in fifths. The open strings, which Sonny 'chimes' at the end of JHB, spell a 'jazzy'-sounding Eb6 add9 chord (or Eb6/9). The cycle of fifths put to very good use, I'd say." bC#F#BE.
