摘    要：武汉钢铁(集团)公司三热轧1580 mm热连轧机飞剪控制系统采用先进的数学模型,精确计算飞剪剪切的各项控制参数,实现飞剪的自动剪切、定位和停车功能。数学模型包括飞剪剪切角计算模型、飞剪剪切启动距离计算模型和飞剪速度目标值计算和调节模型。实际应用结果表明,采用该数学模型将轧件的平均剪切误差控制在10 cm以内,提高了产品产量和成材率。

Abstract: In flying shears control system for 1 580 mm hot strip mill in the Third Hot Rolling Plant of WISCO,advanced mathematical model was adopted to accurately calculate each control parameter of fly shearing,so that cutting,positioning and stop functions of flying shears were achieved.Mathematical model includes cutting angle calculation,shearing start distance calculation and shearing speed calculation.Application results show that average cutting tolerance of rolled strip was controlled within 10 cm,and product output and economic benefits were improved.
