摘　　要：介绍了Φ508 mm PQF连轧管机前台芯棒拨入回转臂的工况要求及设备结构,详细核算了前台芯棒拨入回转臂的电机功率;并阐明了该回转臂动作过程中的位置与速度设定。对于回转臂速度设定,首先根据轧制节奏给出回转臂动作时间,其次根据传动计算出的电机转速并结合工况要求来设定;对于加速到的最大速度则按照变频电机在额定频率时转速值折算到传动轴上的转速来设定。Described in the article are the operation conditions as required for and the equipment structure of the inlet table kick-in rotary arms of the Ф508 mm PQF pipe mill. The electrical motor power for the arm device is calculated carefully for check. And setting of the positions and the speeds as required for the rotary arm movement process are elaborated. The rotary arm speed must be set up with combination of the three elements, i.e., first the rotary arm movement time that is calculated based on the rolling cycle, then the electrical motor＇ s rpm as computed as per the arm rotations, and the operation conditions as well. As for how to accelerate the system to the maximum speed, it must be determined based on the drive spindle＇s rotation rate as converted from the variable-frequency motor＇ s rpm under its rated frequency.
