Nov 12, 2013· types of Automatic Gauge Control (AGC) methods have been developed for hot or cold mill processes. The British Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3].
rolling mill can b e designed as 20 Hi, 12Hi, 8 Hi, 6 Hi, 4 Hi and 2 Hi rolling mills. In India now a days mostly 20 Hi and 4 Hi rolling mills are installed in bi g steel produ ction units.
maximum rolling speed of a cold or foil mill, 8 meters of strip is produced. It is easy to see why Automatic Gauge Control (AGC) is an essential component of modern rolling mills. Comprehensive AGC algorithms incorporate readings from dozens of sensors around the mill. Some of the key AGC input parameters are speed and tension. (See Figure 1)
