| 英文摘要: |
| The process principle of electromagnetic force aided line-heating is introduced. An electromagnetic coil is used during the line-heating process which can generate electromagnetic force to further the formation of steel plate. This new technique can not only improve the heating condition and increase the forming efficiency, but also be beneficial to processing control and enhancing the forming accuracy. This new technique can be used in the formation of thick hull plate and high strength steel plate. The device circuits of the electromagnetic force aided line-heating are investigated and designed including the filtering rectification circuit, recharge circuit, discharge circuit and control circuit. The simulation results testify the rationality and feasibility of the designed circuits. |
