Temperature control device for refining metal solidification structure by use of pulse current

The invention discloses a temperature control device for refining a metal solidification structure by use of pulse current, and belongs to the field of metal solidification control. The temperature control device mainly comprises temperature measurement thermocouples, a temperature control and data acquisition device, and displacement and guiding devices. The device is mainly characterized in that the process temperature is controlled and measured when a metal melt is processed by use of pulse current. The temperature measurement thermocouples measure the temperature of a metal melt in real time, and the temperature control and recording device controls the temperature of the metal melt and acquires data of the temperature. The device has outstanding advantages in application of metal melt processing by pulse current under heating of a tubular resistance furnace. By adopting the device, the temperature of a metal melt can be measured accurately, operation is simple, the error is small, and the influence of pulse current to the process of metal solidification can be analyzed based on acquired data. The device has positive significance to accurate control of metal melt temperature and controllability of the processing process during metal solidification structure refining by use of pulse current.
