In rolling mill, the accuracy and quality of the strip exit hickness aret 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 routine mill inspection, the metallurgist generally cuts a disc from the top and bottom (occasionally the middle) of billets rolled from the first, middle, and last ingots. For certain products, discs are prepared from all the ingots, after rolling to the required billet size. These discs should be cut so as not to .

The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590.
