Title:
METHOD FOR HEATING CONDUCTOR BLANK AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/102861
Kind Code:
A1
Abstract:
Provided are a method for heating conductor blank and apparatus, which is applied to a high-temperature superconducting direct-current induction heating system, a plurality of magnetic field adjusting units comprising magnetic conductance portion (6) and magnetic resistance portion (7) are arranged in the heating system, the method comprises: determining the target axial magnetic field distribution according to target axial temperature distribution of a conductor blank (4) and a preset corresponding relation (S101); determining a weight function according to the target axial magnetic field distribution and the current axial magnetic field distribution (S102); determining an adjustment amount of each magnetic field adjustment unit based on the weight function and a preset mapping relation table (S103); adjusting the proportion of the magnetic conductance portion and the magnetic resistance portion based on the adjustment amount to establish a working air gap magnetic field corresponding to the target axial magnetic field distribution (S104); placing the conductor blank (4) into a preset position in the working air gap magnetic field and rotating the conductor blank (4) to achieve the target axial temperature distribution, so that the conductor blank (4) can be heated more flexibly and accurately according to the target axial temperature distribution.
