But is prone to being involved in oxide slag inclusions which impair material properties. In addition, the equipment has high maintenance cost and limited service life, is difficult to realize continuous production, and has lower production efficiency. The electromagnetic stirring method induces eddy current in the melt by applying an alternating magnetic field, and the eddy current interacts with the magnetic field to generate electromagnetic force to drive the melt to move. However, the initial investment of equipment is huge, the operation energy consumption is high, and the complex electromagnetic field environment can cause interference to other equipment and operators in the workshop. To overcome the high cost and complexity of the above methods, inclined cooling plate methods have been developed. The method has the advantages of simple equipment, low cost and no pollution, but has weak regulation and control capability, poor process stability, and lack of flexibility in fixed inclination angle design, and is difficult to adapt to diversified process requirements.
