摘　　要：转底炉炉床转动控制是关系转底炉冶炼工艺的关键环节。根据转底炉冶炼工艺的要求,提出了一种新的炉床转动控制方法。将异步电机无速度传感器矢量控制应用到炉床转动控制系统中,通过研究含碳球团还原热动力学特性及工艺要求,得出了炉床上物料量与其所需反应时间和炉床转速的关系式,在此基础上建立了系统的仿真模型。仿真结果表明,系统可依据炉床上物料量的波动,适时地控制调整炉床运动转速,以此确保物料反应时间,为改良炉床转动控制提供了一条新途径。The rotating control of rotary hearth fumace （RHF） is a key linking in the process of its smelting. According to the requirement of the rotary hearth furnace smelting process, the paper proposed an improved furnace bed rotation control method. Applying the speed sensorless vector control into hearth rotating control system, and researching the thermal dynamic characters of carbon composite pellets, the relation between furnace bed material quantity and rotational speed is obtained. In the end, the simulation model of the system is es- tablished. The simulation results show that the speed of furnace bed can be controlled timely according material quantity, thus providing a new way for improving hearth rotating control.
