1. A casting-rolling side sealing device with an electromagnetic stirring function, comprising a casting-rolling zone formed by a rotational cooperation a pair of casting rolls, and further comprising:
a pair of side sealing plates configured to cover two side ends of the casting-rolling zone respectively from a casting-rolling starting end to a casting-rolling ending end, wherein a pre-tightening force is formed between one of the side sealing plates and adjacent casting rolls;
a first electromagnetic assembly arranged on each of the side sealing plates, wherein a pulse end of the first electromagnetic assembly releases first pulses along a first axis direction parallel to a direction from the side ends to a center of the casting-rolling zone; the first pulses are configured to generate an electromagnetic stirring effect in the casting-rolling zone, and promote a heat exchange in a microstructure and form a Joule heat effect; and
a second electromagnetic assembly arranged on the each of the side sealing plates, wherein a pulse end of the second electromagnetic assembly releases second pulses along a second axis direction perpendicular to the first axis direction, and the second pulses are configured to act on a side edge of the casting-rolling zone to reduce viscous resistance formed by a contact between the each of the side sealing plates and an end face of a solidified microstructure in an adjacent casting-rolling zone;
wherein the first electromagnetic assembly comprises:
a ceramic core cooperatively fixed on a side, opposite to another side contacting the casting rolls, of the each of the side sealing plates;
a first electromagnetic coil wound around the ceramic core and configured to externally connect with a low-frequency pulse generator, wherein the first electromagnetic coil cooperates with the ceramic core to release the first pulses; and
an adjusting piece arranged on the each of the side sealing plates, wherein an adjusting end of the adjusting piece is configured to connect with the first electromagnetic coil, and capable of controlling a number of turns of the first electromagnetic coil connected with the low-frequency pulse generator to adjust a magnetic induction line density of the first pulses, so as to accurately control a pulse action end in a mechanical level.
