[0060] The 1700 production line of Anshan Iron and Steel Co., Ltd. Hot Rolling Strip Steel Plant uses the roll gap setting calculation model and the AGC automatic thickness control system to control the thickness of the strip and the thickness of the head and tail. The statistical table of the thickness of the strip head and tail in 2010 is shown in the table. 1.

[0063] After adopting the method described in this patent in 2012, good results have been achieved. The continuous over-tolerance of the strip head thickness has been significantly improved, especially the positive over-tolerance of the strip head thickness, which is significantly reduced and positive The number of negative over tolerances has also been reduced, and the thickness hit rate has been improved to a certain extent; see Table 2 for specific statistics.
