Anticipatory Automatic Gauge Control
Precision measuring normally requires an entrance gauge, which records the thickness of the material going into the rolling mill. This is referred to as anticipatory automatic gauge control. The entrance thickness gauge adjusts the rolls in microseconds if there are any changes in thickness. The exit gauge records the thickness, and the rolls adjust based on the thickness of the material going through the mill. Adjustments are made in microseconds to hold the final gauge. There are many types of automatic gauge controls, and because of the latest technology in automatic gauge control and shape control, it is now possible to roll material with extreme accuracy at speeds up to 7,000 FPM.
