Technical Field

[0002] In the process of metal smelting or melting, it is usually necessary to fully stir the liquid metal. There are mechanical stirring methods, air blowing methods, and magnetic stirring methods. The magnetic stirring method has been increasingly widely used due to its advantages such as controllable stirring mode and no direct contact with the melt. In the process of metal smelting, stirring can improve the melting efficiency of metal objects, solve the uneven temperature between the melts in the furnace, and overcome the oxidation and burning caused by uneven temperature during the smelting process. By fully stirring the metal liquid, the alloy composition in the metal liquid can be made uniform, and impurities in the melt can be discharged through stirring;

[0003] The traditional bottom-mounted melting furnace stirrer has only one magnetic body to generate a stirring magnetic field, and the size of the magnetic body is changed to adapt to different molten liquid distribution areas. However, since the magnetic body is a rotating body, the coil winding and the arrangement of the magnetic steel are limited. The actual stirring magnetic field area is a circle centered on the rotation axis, which will cause the stirring magnetic field area to be inconsistent with the molten liquid distribution area, resulting in a large number of blank areas for magnetic field stirring in the melting furnace, resulting in insufficient stirring of the molten liquid.

[0004] Therefore, it is necessary to improve the bottom-mounted melting furnace agitator so that it can have a certain reciprocating transmission effect while being driven in rotation, so as to further improve the correspondence between the stirring magnetic field area and the molten liquid distribution area and enhance the stirring adequacy.

[0033] Here’s how it works:

[0034] When the stirrer of the bottom-loading smelting furnace is to be used, multiple magnetic systems can be arranged in combination to achieve the purpose of flexibly adapting to the stirring area; according to the requirements of the stirring area, the arrangement mode of the magnetic system body is set to increase the overlapping area of ​​the stirring magnetic field and the smelting liquid distribution. When the equipment is working, the connecting walking mechanism 2 is first actuated to move the equipment platform along the track to the stirring working position at the bottom of the smelting furnace. After the relative position of the magnetic system body 5 and the smelting liquid is accurately adjusted by inching control, the connecting walking mechanism 2 is suspended, and then the lifting mechanism 3 is actuated, and the equipment platform moves toward the bottom of the smelting furnace. After reaching the specified position, the limit switch is triggered, and the lifting mechanism 3 stops working. After the equipment enters the working position, the magnetic system body 5 is excited and started to generate a working magnetic field, and then the rotating mechanism 4 works, and the magnetic system body 5 rotates around its own axis to form a periodically alternating stirring magnetic field, so as to achieve large-area and sufficient stirring of the smelting liquid. After the stirring work is completed, the rotating mechanism 4 stops working, the excitation power is turned off, and then the working platform of the lifting mechanism 3 is reset, and the connecting walking mechanism 2 moves to move the equipment to the initial position, thereby completing the rapid stirring activity;

[0035] In order to further improve the corresponding effect between the stirring magnetic field and the molten liquid distribution area and enhance the stirring sufficiency, an extended transverse movement device 7 is provided on both sides of the lower end of the platform 1 to realize intermittent reciprocating transverse movement transmission. First, when the limit device 33 provided inside the lifting mechanism 3 is in contact with the ground with the lifting transmission, the support plate 71 connected to the limit device 33 through the connecting block 74 inside the extended transverse movement device 7 can be moved downward to contact with the ground, so as to realize auxiliary limit cooperation and ensure the stability of the subsequent reciprocating transverse movement transmission. In addition, the anti-skid pad 72 correspondingly bonded to the bottom of the support plate 71 can further improve the resistance stability and anti-skid property. In this way, the reciprocating transverse movement preparation activity can be completed.

[0036] Next, the servo motor 772 provided inside the push-pull assembly 77 can be driven to enable the servo motor 772 to realize the rapid rotation of the pulley 773 connected to the bottom. As the pulley 773 rotates, the belt 774 connected to the outside of the pulley 773 can be rotated accordingly to realize the same direction driving of the turntable 775 connected to the left side. As a result, the turntable 775 as a whole can realize stable and rapid circumferential rotation, and the push-pull rod 776 connected to the upper end of the turntable 775 can be rotated to realize reciprocating push-pull transmission. In this way, the push-pull rod 776 on the left side can be connected to the push-pull rod 776 on the right side. The connecting strip 777 connected to the side will cooperate with the reciprocating push-pull effect to make the slider 778 fastened at the upper end drive the vertical rod 76 and the fixed rod 75 to move back and forth horizontally. In this way, the platform 1 as a whole can intermittently move back and forth horizontally, so that the magnetic system body 5 can not only be coordinated with the rotating mechanism 4 to achieve rotating electromagnetic stirring, but also move back and forth horizontally to expand the rotating stirring range, so that the liquid inside the smelting furnace is fully stirred and processed, so as to further improve the corresponding effect of the stirring magnetic field area and the molten liquid distribution area and significantly enhance the stirring adequacy.

[0037] At the same time, because the slider 778 is slidably connected to the outer side of the vertical rod 76, it is not easy to cause jamming when the limit device 33 drives the support plate 71 to move up and down, and the support rod 73 arranged at the upper left end of the support plate 71 can enhance the stability of the up and down lifting activities of the support plate 71.

[0038] The utility model provides a bottom-mounted smelting furnace stirrer with multiple magnetic systems. By setting an extended transverse movement device 7, that is, under the transmission cooperation of the pulley 773, belt 774 and turntable 775 arranged inside the push-pull assembly 77, the push-pull rod 776 connected to the upper end of the turntable 775 can realize the reciprocating push-pull of the connecting bar 777 and the slider 778, thereby, the fixed rod 75 and the vertical rod 76 arranged inside the front and rear sides of the platform 1 can realize the intermittent reciprocating transverse movement of the entire platform 1 with the transverse push-pull transmission, thereby expanding the electromagnetic stirring range, making the stirring magnetic field area and the molten liquid distribution area efficiently correspond and match, thereby achieving the advantages of further improving the corresponding effect of the stirring magnetic field area and the molten liquid distribution area and significantly enhancing the stirring adequacy.
