Background Technique

[0002] In the current continuous casting process of metal materials at home and abroad, the continuous casting technology with water-cooled molds is used, which will be subverted by the magnetic levitation continuous casting technology. The magnetic levitation continuous casting technology is an advanced metal casting technology that uses a magnetic field to levitate and control the flow of molten metal, thereby realizing the production of high-quality metal castings. This technology is particularly suitable for the production of all metal materials such as steel, aluminum, and copper.

[0003] It is currently known that the alternating magnetic field used in the magnetic levitation continuous casting technology is composed of a magnetic conductor, a conductor, and a ≈10KHz alternating power supply.

[0004] Currently, the induction heating equipment used in the manufacturing of heating equipment in various domestic industrial industries is also composed of a magnetic conductor, a conductor, and a 5 - 30KHz alternating power supply. For the magnetic conductor, both are bonded together using an adhesive. Using an adhesive not only complicates the operation but also increases the magnetic resistance. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a special-shaped magnetic field combination device that uses externally attached permanent magnets to enhance the magnetic induction intensity of an alternating magnetic field, so as to solve the problem that using an adhesive not only complicates the operation but also increases the magnetic resistance proposed in the related technology.

[0006] To achieve the above objective, according to one aspect of the utility model, a special-shaped magnetic field combination device that uses externally attached permanent magnets to enhance the magnetic induction intensity of an alternating magnetic field is provided, including: a base component that provides support for the device;

[0007] A magnetic force component is provided on the base component. The magnetic force component includes a plurality of permanent magnets. The permanent magnets are used to enhance the magnetic induction intensity B of the alternating magnetic field generated by the device. The permanent magnets are used to bond the magnetic conductor components of the device, making the alternating magnetic field into a special-shaped magnetic field.

[0008] Further, the base component includes a molten metal column, a plurality of water-cooled copper tubes, and a magnetic core.

[0009] Further, the magnetic core is in a "mountain" shape, and grooves are provided on both sides of the magnetic core. The permanent magnets are adsorbed below both sides of the magnetic core.

[0010] Further, the water-cooled copper tubes are all located in the grooves of the magnetic core.

[0011] Furthermore, the copper liquid column is located in the middle above the magnetic core.

[0012] Furthermore, the magnetic assembly also includes a plurality of constraint plates and a plurality of transition plates.

[0013] Furthermore, the transition pieces are located above both side wings of the magnetic core.

[0014] Furthermore, the constraint plates are all located above the transition plates, and the permanent magnets are adsorbed on the outside of the contact portion between the constraint plates and the transition plates.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the constraint sheet and the transition sheet are fixed on the magnetic core by the adsorption force of the permanent magnet, and no adhesive is used for bonding, thereby eliminating the magnetic resistance loss caused by the use of the adhesive; by adding the permanent magnet, the magnetic induction intensity B of the alternating magnetic field is increased. When the magnetic induction intensity B is increased, the output of the alternating current can be reduced accordingly, thereby achieving the purpose of saving electric energy.

[0021] The magnetic assembly is arranged on the base assembly, and the magnetic assembly includes a plurality of permanent magnets 6. The permanent magnets 6 are used to enhance the magnetic induction intensity B of the alternating magnetic field generated by the device.

The permanent magnets 6 are used to bond the magnetic conductive parts of the device, so that the alternating magnetic field becomes a special-shaped magnetic field, and no adhesive is used for bonding, thereby eliminating the magnetic resistance loss caused by the use of the adhesive.

[0022] The base component includes a metal liquid column 1, a plurality of water-permeable copper tubes 4 and a magnetic core 5.

[0023] The magnetic core 5 is in a "mountain" shape, with grooves on both sides of the magnetic core 5. The permanent magnets 6 are adsorbed below both sides of the magnetic core 5. The magnetic core 5 is connected to an external alternating current and converts the alternating current into an alternating magnetic field.

When the magnetic induction intensity B is increased, the output of the alternating current can be reduced accordingly, thereby achieving the purpose of saving electric energy; at the same time, the adsorption force of the permanent magnet 6 will strengthen the fixation of the constraint sheet 2 and the transition sheet 3 on the magnetic core 5, and no adhesive is used for bonding, thereby eliminating the magnetic resistance loss caused by the use of the adhesive.
