英文摘要：

In the process of line heating, a certain frequency and approximatively consecutive force of constraint can be applied to steel plates by using pulsed electromagnetic force. It can not only improve the condition of steel plates heated at high temperatures, improve the efficiency of steel forming but also be conducive to the process control and improvement of the forming accuracy. According to the actual needs of electromagnetic force assisted line heating process, the control circuit design ideas of the electromagnetic force assisted line heating device and the function of its branch circuits are introduced. After using a digital oscilloscope and 5v, 12V, 20V power to detect and analyze signal output of the material object of circuit, the results verify the correctness of the design of circuit.
