Description

Technical Field

[0001] This utility model relates to the field of furnace stirring technology, specifically to a mold steel melting furnace with electromagnetic stirring function. Background Technology

[0002] Stirring is required during smelting in a melting furnace, mainly to improve the quality of the melt, increase smelting efficiency, and ensure process stability. When smelting mold steel, electromagnetic stirring is generally used.

[0003] The electromagnetic stirrer structure includes a telescopic support frame structure, with an electromagnetic generator fixed on the top of the telescopic support frame to facilitate electromagnetic stirring inside the furnace. However, existing electromagnetic stirrers can generally only be attached to the bottom of the furnace body, and can only first generate a magnetic field reaction on the melt at the bottom, and then mobilize the entire melt to achieve rotation and stirring. The start-up is slow and the stirring efficiency is low. In addition, the electromagnetic stirrer is mostly a single cooling water channel structure. Since the temperature is high during steel smelting, relying on a single cooling water channel will result in poor cooling effect inside the stirrer, affecting the overall service life of the equipment. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing electromagnetic stirrers are mostly attached to the furnace bottom, stirring the melt at the bottom first, resulting in slow start-up, low efficiency, and poor cooling due to a single cooling water path, which affects the lifespan of the equipment.

[0005] To solve the above problems, the technical solution adopted by this utility model is a mold steel melting furnace with electromagnetic stirring function, including a furnace body, a support platform fixed on the top of the furnace body, a foundation below the furnace body, a pair of support columns and a pair of telescopic cylinders between the support platform and the foundation, a slide rail in the foundation, an electromagnetic stirring structure in the slide rail, the electromagnetic stirring structure including a support platform, a ring frame fixed on the top of the support platform, two cooling water channels symmetrically opened inside the ring frame, an electromagnetic coil inside the cooling water channel near the inner side of the ring frame, a connector structure fixed on one side of the ring frame, the connector structure including an electromagnetic coil connector and a water inlet, and a water outlet on the side of the connector structure.

[0006] As a further embodiment of this utility model: a partition is fixed in the middle of the inner side of the ring frame between the two cooling water channels to separate the two cooling water channels. A through hole is provided on the side of the partition for the electromagnetic coil to connect, and the through hole is sealed when the wire is threaded through.

[0007] As a further embodiment of this invention: the ring frame is installed on the outer side of the bottom of the furnace body, so that the melt can be better affected by electromagnetic fields, thereby speeding up the stirring start-up time.

[0008] As a further embodiment of this utility model: a connecting platform is fixed on the lower side of the ring frame, and a scissor telescopic support structure is provided below the connecting platform, which can drive the ring frame to move up and down. Two pairs of limit frames are provided at the bottom of the scissor telescopic support structure, and several rollers are rotatably provided inside the limit frames to facilitate the stable movement of the device on the slide rail. A slide rail is fixed in the slide rail at the limit frame.

[0009] As a further embodiment of this utility model: the electromagnetic coil connector is electrically connected to an external power source, and the water inlet and outlet are connected to an external cooling water circulation system.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds a double cooling water channel structure, which can remove the heat in the ring frame in time, improve the heat dissipation efficiency, and increase the service life of the equipment. It also adds a ring-shaped electromagnetic coil structure, which can be covered on the side of the furnace body, thereby improving the electromagnetic stirring effect and reducing the stirring start-up time.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

The electromagnetic stirring structure includes the support platform 2, and a ring frame 4 is fixed on the top of the support platform 2. The ring frame 4 is covered on the outer side of the bottom of the furnace body 1, so that the melt can be better affected by electromagnetic waves, thereby speeding up the stirring start-up time. Two cooling water channels 4.1 are symmetrically opened inside the ring frame 4, which can respectively cool the inside of the ring frame 4. The electromagnetic coil 5 is used for heat dissipation. The electromagnetic coil 5 is installed inside the cooling water channel 4.1 near the inner side of the ring frame 4 to generate electromagnetic waves so as to affect the melt and achieve a stirring effect. A connector structure is fixed on one side of the ring frame 4. The connector structure includes an electromagnetic coil connector 6 and a water inlet 4.2. A water outlet 4.3 is provided on the side of the connector structure. A partition 7 is fixed in the middle of the inner side of the ring frame 4 between the two cooling water channels 4.1 to separate the two cooling water channels 4.1. A through hole is opened on the side of the partition 7 for the electromagnetic coil 5 to communicate, and the through hole is sealed when the wire is threaded.

[0021] Combined with appendix Figure 1 , 4 It can be seen that a connecting platform 8 is fixed on the lower side of the ring frame 4, and a scissor telescopic support structure 9 is provided below the connecting platform 8, which can drive the ring frame 4 to move up and down. Two pairs of limit frames 10 are provided at the bottom of the scissor telescopic support structure 9, and several rollers 11 are rotatably provided inside the limit frames 10 to facilitate the stable movement of the equipment on the slide rail 12.
