The rolling pace control process for high speed wire rod is introduced. The existing rolling pace control methods and problems about high speed wire red are analyzed. On the basis of this, methods for improving rolling control models have been proposed. The design method for the rolling speed calculation model has been detailed, and a closed loop control model for heat - insulating rolling table has been established. And then a rolling table deceleration control emulation analysis has been made. After that the calculation formulas for speed and time were redesigned and a deceleration control model were modified. Since the new control model has been put into use in the work field, its effect has been improved a lot, its control accuracy raised, and tapping time for wire rod reduced.
