| description | The embodiment of the invention provides a method for improving the thickness control precision of hot-rolled strip steel, which comprises the following steps of: dividing the strip steel into three strip steel parts, namely a head section, a middle section and a tail section in advance, and respectively setting preset thickness compensation values for the head section, the middle section and the tail section; correcting the strip steel thickness data measured by the thickness gauge of the finishing mill by using a preset thickness compensation value corresponding to the strip steel part according to the strip steel part which is currently rolled by the roller to obtain corrected strip steel thickness data; and inputting the corrected strip steel thickness data to an AGC thickness control system to control a roll gap of a roll in real time so as to control the strip steel thickness at the strip steel part.
