Description

Technical Field

[0001] The utility model relates to the technical field of combined coils, in particular to a high-frequency induction heating combined coil. Background Art

[0002] By controlling the current and heating time of the coil, the heat treatment process of the metal, such as annealing, quenching, and tempering, can be achieved. This heating method can accurately control the temperature distribution of the metal and ensure the heat treatment effect. Coil heating of metal is an efficient and accurate heating method widely used in industrial production. The magnetic field generated by the coil induces eddy currents in the metal, achieving rapid heating of the metal.

[0003] In the prior art, when most combination coils heat the motor casing, the material of the motor casing is different, which results in different heating frequencies required for the motor casing. Therefore, the entire coil needs to be replaced to adapt the heating frequency of the motor casing, which directly leads to a significant increase in the manpower and material resources required for the replacement, and indirectly leads to an increase in the required cost. In the prior art, the outer surfaces of some combination coils are directly exposed to the air, and under the influence of the environment, the service life of the combination coils is very likely to be reduced, which directly leads to a significant increase in the required cost.
