The excitation coil of induction heating is the primary circuit, and the molten steel is the secondary circuit. By inputting variable frequency current to the excitation coil, high-intensity magnetic field is generated in the iron core, so that the connected molten steel generates induced current, thereby achieving continuous heating on the molten steel.
Non-contact heating: the reheat of molten steel reaches 3°C/ min; Achieve constant temperature casting with optimum overheat, and the accuracy of temperature control is up to土3°C; Decrease the on-line temperature of the ladle (10~15°C); Save energy; It can effectively reduce total oxygen content in molten steel and remove small inclusions.
Parameters of initiative temperature control: Decrease the on-line temperature of the ladle(10-15°C); Heating rate: (1-3)°C/min; Target temperature of overheating control: target temperature (±3°C). Heating in the channel enables the heated molten steel form an upflow from the outlet of the channel, which causes the inclusions float up to the free surface to be absorbed by the covering agent, and the up flow also promotes mixing of the molten steel in the tundish, homogenizing the temperature distribution.
