Abstract

The invention discloses a method and equipment for heating a conductor blank based on closed-loop control, which are applied to a high-temperature superconducting direct-current induction heating system, and the method comprises the following steps: determining a control instruction set of a servo motor in a magnetic field adaptive adjustment unit according to target axial temperature distributionof the conductor blank; sequentially controlling the servo motor to rotate based on the control instruction set so as to enable the magnetic field adaptation unit to reach position distribution corresponding to the target axial temperature distribution; obtaining the measured axial temperature distribution of the heated conductor blank under the position distribution; and performing closed-loop control according to the target axial temperature distribution and the measured axial temperature distribution to enable the measured axial temperature distribution to reach preset heating precision, thereby realizing effective control of a heating temperature error in a process of heating a conductor blank according to a specified axial temperature distribution target, and improving temperature regulation and control precision.

Description

technical field [0001] The present application relates to the technical field of high-temperature superconducting direct current induction heating, and more specifically, relates to a method and equipment for heating conductor blanks based on closed-loop control. Background technique [0002] The current high-temperature superconducting DC induction heating technology usually generates a strong magnetic field by direct current through a superconducting magnet. An appropriate magnetic flux concentrator is selected to concentrate the magnetic field to the working air gap of induction heating, and the motor drives the conductor blank in the working air gap. Middle rotation (that is, the conductor cuts the magnetic field line), so that the eddy current heat generation phenomenon is formed in the blank workpiece, and the effect of temperature rise is achieved. Different from the traditional electromagnetic induction heating technology, the internal heating efficiency of the bille...
