Control method for improving rolling rhythm of high-speed bar production line

The invention discloses a control method for improving the rolling rhythm of a high-speed bar production line. The method specifically comprises the following steps that A, head and tail rolling is conducted; B, a loop rising control mode is optimized; C, loop tension control is optimized, specifically, loop tension control is modified, and loop tension is controlled in a large-proportion rising and small integral adjusting mode; and D, optimizing transmission parameters in a high-speed area, namely continuously optimizing and adjusting a speed loop and a current loop by adopting a double-closed-loop speed regulation system adjusting mode, so that the equipment runs in an optimal state. According to the control method for improving the rolling rhythm of the high-speed bar production line, head and tail rolling is adopted, and the rolling interval fluctuation is smaller than 0.3 S; loop rising and tension control modes are optimized, and quick response of the loop is achieved; a transmission control system ado
