[0022] Working principle: When installing the electromagnetic stirring device based on the continuous casting mold, multiple dovetail tenons 17 are pre-fixed around the outer wall of the coil-fixed ceramic frame 5 and inserted correspondingly into multiple dovetail grooves 18 opened around the inner wall of the mold adapter frame 4. The buffer pads 21 on the bottom side of the inner wall of the dovetail groove 18 play a buffering role during the positioning process, reducing the collision impact during installation. At the same time, they also provide buffering for the vibration during the subsequent continuous casting process. After positioning, multiple screws 6 with high-temperature resistant gaskets 7 first pass through the mold adapter frame 4 and then are screwed into the outer wall of the coil-fixed ceramic frame 5. During the tightening process, the high-temperature resistant gaskets 7 protect the outer wall of the mold adapter frame 4 on the one hand and enhance the tightness of the fixation on the other hand. Moreover, these screws 6 also respectively penetrate the corresponding dovetail tenons 17 and are threadedly connected to the outer wall around the mold adapter frame 4 to further reinforce the connection and ensure the stability of the entire structure. Subsequently, high-temperature resistant fitting pads 9 are installed in multiple coil pattern fitting grooves 8 on the inner wall of the coil-fixed ceramic frame 5. The high-temperature resistant fitting pads 9 can closely fit the main electromagnetic coil group 10 in the high-temperature continuous casting environment, buffer the influence of thermal expansion and contraction, prevent its displacement, and ensure the stable and accurate electromagnetic stirring. Then, the main electromagnetic coil group 10 is placed therein, and multiple screws 11 are used to tightly fit and fix the main electromagnetic coil group 10 from the outside to prevent its displacement. Multiple conical support feet 19 cooperate with rubber pads 20 to ensure that the device is placed stably and can buffer vibration, effectively solving the problem that the main electromagnetic coil group 10 is displaced due to vibration and thermal expansion and contraction during the continuous casting process, ensuring the accuracy and stability of the electromagnetic stirring, and thus improving the quality of the continuous casting products; Moreover, when it is necessary to adjust the height of the device to adapt to the ground with different flatness, the operator rotates the fixing nut 204. Since the fixing nut 204 is fixedly connected to the bottom of the threaded column 203, and the threaded column 203 is in threaded cooperation with the threaded groove 202 opened at the bottom side inside the U-shaped support block 201, rotating the fixing nut 204 can drive the threaded column 203 to move up and down in the threaded groove 202, thereby realizing the adjustment of the device height and enabling the device to remain horizontal on the uneven ground. After the height adjustment is completed, it is fixed by rotating the fastening nut 205. The fastening nut 205 moves upward on the threaded column 203, and the fastening gasket 206 connected to its top rises accordingly until it closely fits the bottom of the U-shaped support block 201. The fastening gasket 206 increases the contact area, makes the fastening force distribution more uniform, prevents the fastening nut 205 from loosening, and ensures that the height remains stable during the use of the device and will not change due to vibration factors, solving the problems of inconvenient height adjustment and insecure fixation in the prior art and improving the stability of the device placement.
