Description

Technical Field

[0001] The present invention relates to the technical field of sintering machines, and in particular to an electromagnetic stirring system and method for a belt sintering machine. Background Art

[0002] A belt sintering machine is a type of industrial equipment primarily used for the sintering of iron ore. It produces sintered ore for blast furnaces by mixing iron ore powder with auxiliary materials and sintering them at high temperatures. This machine typically consists of a long moving belt that transports and heats the raw materials, while a ventilation system on top controls the temperature and oxygen supply. The design of the belt sintering machine ensures uniform heating and sintering of the raw materials during movement, thereby improving sintering efficiency and the quality of the sintered product. The fluidity of the molten liquid phase in the belt sintering machine has a significant impact on the quality of the sintered ore. Poor fluidity means that the molten material is not evenly distributed throughout the ore layer, which can lead to structural inhomogeneities in the sintered ore, affecting its overall quality and hindering effective chemical reactions, such as the reduction of iron oxides. This can reduce sintering efficiency and product quality, and result in poor permeability in the sintered ore, which can be detrimental to subsequent reduction and smelting processes.

[0003] During the sintering process of the conventional belt sintering machine, the flow of the molten liquid phase is affected by the fluidity of the fluid itself, gravity, and wind pressure. Gravity causes the molten liquid phase to permeate downward, resulting in excessive concentration of the liquid phase at the bottom, thereby affecting the quality of the sintered blocks.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Please see the attached Figure 1-4 In one embodiment of the present invention, an electromagnetic stirring system for a strand sintering machine includes a moving system 10, an electromagnetic stirring mechanism 20, a cooling system 30, a monitoring system 40, and a control system 50. The specific solution is as follows:

[0042] The mobile system 10 is used to adjust the position of the electromagnetic stirring mechanism 20, is arranged at intervals above the sintering machine trolley 60, and is movably arranged along the extension direction of the sintering machine trolley 60; the electromagnetic stirring mechanism 20 is used to generate force on the molten iron in the sintering machine trolley 60 to stir the molten iron, is connected to the bottom of the mobile system 10, and the electromagnetic stirring mechanism 20 is adjustably arranged along the vertical position; the cooling system 30 is used to reduce the operating temperature of the electromagnetic stirring mechanism 20, and is built into the electromagnetic stirring mechanism 20; the monitoring system 40 is used to collect real-time data of the molten iron in the sintering machine trolley 60, is connected to the sintering machine trolley 60, and is communicated with the control system 50; the control system 50 is used to receive real-time data fed back by the monitoring system 40 and output current to the electromagnetic stirring mechanism 20, and the control system 50 is electrically connected to the electromagnetic stirring mechanism 20 and the mobile system 10.

[0043] Specifically, the mobile system 10 can adjust the position of the electromagnetic stirring mechanism 20. The position of the electromagnetic stirring mechanism 20 is different, and the relative position and angle between the magnetic field generated by it and the target sintering machine trolley 60 molten iron (the molten iron is the molten liquid of the sintering machine trolley 60) are also different. It can adapt to changing the magnetic field strength to adjust the generated force, and can also enhance the stirring effect for the molten iron area with poor fluidity, thereby meeting the needs of different stirring conditions in actual work and improving the adaptability of the device. It is arranged at intervals above the sintering machine trolley 60 so that the electromagnetic stirring mechanism 20 can be arranged at intervals above the sintering machine trolley 60 after installation; the electromagnetic stirring mechanism 20 is used to affect the flow of molten iron, and it adopts a combination of an electromagnetic coil 210 and a shell 220, and the electromagnetic coil 210 is used to constitute a stirring The core component of the device is used to generate a changing magnetic field to stir the molten iron. It is designed to use multiple electromagnetic units (composed of a coil group 211 and a magnetic permeability block) to enhance the magnetic field strength and uniformity. Preferably, eight electromagnetic units can be arranged at intervals along the circumference of the electromagnetic coil 210, and the magnetic permeability block can use silicon steel sheets 212 to utilize its high magnetic permeability to enhance the magnetic field strength. The coil group 211 can use a copper coil with good conductivity, so that the current passes through the coil efficiently to generate a stronger magnetic field. It is worth mentioning that the electromagnetic coil 210 can be set directly above the sintering machine trolley 60 when it is set, so as to ensure uniform distribution of the magnetic field. The shell 220 is used to cover the outside of the electromagnetic coil 210 and play a role in installation and connection so that it can be installed on the mobile system 10.

[0044] Among them, the principle of the electromagnetic stirring mechanism 20 is mainly based on the action of the Lorentz force, which is the force generated when an electric current passes through a conductor in a magnetic field. In application, the molten iron itself acts as a conductor, and the changing magnetic field generated by the electromagnetic coil 210 excites the current in the molten iron, and then affects its flow direction and speed through the Lorentz force, specifically F = I × (L × B); I is the current intensity in the conductor, L is the length of the conductor, which in this case can be understood as the length of the flow path of the molten iron, and B is the magnetic field strength; in the electromagnetic stirring application, by controlling the current in the electromagnetic coil 210 (that is, changing the current intensity I) and the magnetic field strength (B), the magnitude of the Lorentz force acting on the molten iron can be accurately adjusted, thereby affecting the flow speed and direction of the molten iron, so it is necessary to use the control system 50 to adjust the current intensity and current frequency.

[0045] In detail, the control system 50 is used to provide current to the electromagnetic coil 210. The control system 50 changes the strength and direction of the magnetic field by adjusting the current intensity and the frequency of the alternating current in the electromagnetic coil 210. The strength of the electromagnetic field directly affects the magnitude of the Lorentz force, and the change in the direction of the magnetic field affects the direction of the molten iron flow. Therefore, the control system 50 is electrically connected to the electromagnetic coil 210; and in order to understand the state changes of the molten iron in real time, it is necessary to set the monitoring system 40 to monitor the flow state of the molten iron and the resistance of the material layer in real time. In this way, the control system 50 also has a synchronous collection system. The monitoring system 40 is used for analysis. These data (the flow state of the molten iron and the resistance of the material layer) are fed back to the control system 50 in real time. The control system 50 adjusts the current and frequency of the electromagnetic coil 210 according to these feedbacks to achieve precise control of the flow of the molten iron. Therefore, the monitoring system 40 needs to be communicated with the control system 50 to feedback and receive data. The monitoring system 40 needs to be connected to the sintering machine trolley 60 to be set on the sintering belt of the sintering machine trolley 60 to ensure accurate data collection, and it is best installed in a position close to the electromagnetic stirrer to ensure that the changes in the flow and resistance of the material layer can be accurately monitored.

[0046] It is worth noting that the main principle of the electromagnetic coil 210 of the present application is to rely on a group (two oppositely arranged) of coil groups 211 to generate a magnetic field after being energized, and then the adjacent group (two oppositely arranged) of coil groups 211 are energized to generate a magnetic field after the power is cut off. After this cycle, a rotating magnetic field is generated. Its principle is similar to that of a three-phase motor. Therefore, such a changing magnetic field will generate a lot of heat during operation. Therefore, a cooling system 30 needs to be designed to maintain the normal operating temperature of the equipment. It is built into the electromagnetic stirring mechanism 20 and is specifically arranged in the shell to wrap the electromagnetic coil 210 to achieve a better cooling effect.

[0047] As a preferred embodiment of the present invention, the mobile system 10 includes a mobile track 110, a power trolley 120 and a connecting plate 130. The power trolley 120 has a power wheel 121. The inner side of the power wheel 121 is radially protruded to form a flange 122.

[0048] The movable rail 110 is arranged parallel to the sintering machine trolley 60, the power wheel 121 of the power trolley 120 is arranged on the movable rail 110 and the flange 122 is abutted against the inner side of the movable rail 110, the connecting plate 130 is connected to the bottom of the power trolley 120 and is arranged vertically adjustable, and the electromagnetic stirring mechanism 20 is connected to the connecting plate 130 and is arranged at intervals above the sintering machine trolley 60.

[0049] It should be noted that the movable track 110 is arranged parallel to the top of the sintering machine trolley 60 so as to be consistent with the flow direction of the molten iron, so that the electromagnetic stirring mechanism 20 is still directly above the sintering machine trolley 60 although its position has changed after movement. The connecting plate 130 is used for the installation of the electromagnetic stirring mechanism 20, which is connected to the bottom of the power trolley 120 to drive the electromagnetic stirring mechanism 20 to be movable and adjustable along the extension direction of the sintering machine trolley 60. Furthermore, the connecting plate 130 is arranged to be adjustable vertically, so that the vertical position of the electromagnetic stirring mechanism 20 can also be adjusted to adjust the spacing between the electromagnetic stirring mechanism 20 and the molten iron to adjust the magnetic field distribution; and the flange 122 plays a guiding role by clamping the movable track 110 together with the power wheel 121 itself, so that the power trolley 120 can move along the movable track 110 when moving without any deviation.

[0050] As a preferred embodiment of the present invention, the cooling system 30 includes a heat dissipation water pipe 310, a water inlet 320 and a water outlet 330. The water inlet 320 and the water outlet 330 are respectively protruded from the side walls of the outer shell 220. The heat dissipation water pipe 310 is built into the outer shell 220 and is arranged around the outer shell 220. The water inlet 320 is used to connect cooling water and is connected to the water inlet end of the heat dissipation water pipe 310. The water outlet end of the heat dissipation water pipe 310 is connected to the water outlet 330.

[0051] It is worth noting that the cooling system 30 cools the electromagnetic coil 210 by connecting cooling water. The cooling electromagnetic coil 210 is surrounded by a heat dissipation water pipe 310 arranged in a surrounding manner in the outer shell 220. The water inlet end of the heat dissipation water pipe 310 is arranged to be connected to the water inlet 320, and the water inlet 320 is directly connected to the external cooling water source to connect to the cooling water, while the water outlet end of the heat dissipation water pipe 310 is arranged to be connected to the water outlet 330, and the water outlet 330 is used to discharge the cooling water whose cooling temperature has dropped after cooling, so as to facilitate the connection of new cooling water.

[0052] Furthermore, the heat dissipation water pipe 310 extends in a serpentine shape along the circumference of the shell 220, that is, it forms a multi-section bend form, which can greatly increase the circumferential arrangement length of the heat dissipation water pipe 310, so that the cooling water will stay longer when flowing through, and the cooling area is increased, thereby enhancing the cooling effect.

[0053] As a preferred embodiment of the present invention, the mobile system 10 also includes a vertical adjustment component 140, which includes two screw rods 141 arranged relatively along the length direction of the connecting plate 130 and four slide rods 142 distributed in a matrix shape. The top ends of the slide rods 142 and the screw rods 141 are both connected to the power trolley 120, and the bottom ends of the slide rods 142 and the screw rods 141 pass through and extend out of the connecting plate 130, and the screw rods 141 are threadedly connected to the connecting plate 130.

[0054] It is worth noting that the vertical movement adjustment of the connecting plate 130 is achieved by adopting the screw rod 141. The top end of the screw rod 141 is connected to the power trolley 120 and is rotatably arranged, and is also threadedly connected to the connecting plate 130. In this way, the connecting plate 130 can be adjusted up and down by rotating the threaded pair to adjust the vertical position of the electromagnetic stirring mechanism 20; and the sliding rod 1421 plays a certain guiding role, so that the four corners of the connecting plate 130 can be raised and lowered synchronously and evenly when moving. Therefore, the sliding rod 142 adopts four matrix-shaped distribution forms to respectively penetrate the connecting plate 130.

[0055] Furthermore, the monitoring system 40 includes a flow rate sensor and a resistance sensor, both of which are installed on the sintering belt of the sintering machine trolley 60 , and both of which are in communication connection with the control system 50 .

[0056] It should be noted that the flow rate sensor is used to monitor the flow state of the molten iron, and the resistance sensor is used to monitor the material layer resistance of the molten iron. By feeding these data back to the control system 50 in real time, the control system 50 adjusts the current and frequency of the electromagnetic coil 210 according to these feedbacks to achieve precise control of the flow of the molten iron; further, a temperature sensor can also be set to monitor the working temperature of the electromagnetic coil 210 in real time, and to cool it in time through the cooling system 30 to avoid equipment damage.

[0057] The present application also provides an electromagnetic stirring method for a belt sintering machine, which is applied to the electromagnetic stirring system for the belt sintering machine as described above, comprising the steps of:

[0058] S1, setting the initial current parameters of the control system 50 according to the initial state and target flow state of the molten iron, and determining the initial position of the electromagnetic stirring mechanism 20; wherein, the initial current parameters include initial current intensity and initial current frequency; it should be noted that an initial value is set in this way so that the current intensity can be gradually increased, the current frequency can be changed, etc. based on this initial value, thereby changing the magnetic field and adjusting the stirring force.

[0059] S2, provides current to the electromagnetic stirring mechanism 20 through the control system 50, so that the electromagnetic stirring mechanism 20 generates a force for stirring the molten iron of the sintering machine trolley 60; it should be noted that after power is turned on, the current passes through the electromagnetic coil 210 to generate a magnetic field, and the molten iron acts as a conductor to pass through the magnetic field, thereby generating a Lorentz force as a force for stirring the molten iron, achieving a stirring effect, and affecting the flow of the molten iron.

[0060] S3, real-time data of the molten iron in the sintering machine trolley 60 after electromagnetic stirring is obtained through the monitoring system 40, and fed back to the control system 50; it can be understood that after the Lorentz force is generated for stirring, the real-time flow conditions of the molten iron in the sintering machine trolley 60 will change, including the flow rate of the molten iron, the resistance of the material layer, etc. After the real-time data is obtained through the monitoring system 40 (flow rate sensor, resistance sensor), it is fed back to the control system 50 to facilitate subsequent targeted adjustments.

[0061] S4, analyzes the real-time data of the molten iron of the sintering machine trolley 60, outputs the correction current parameters through the control system 50, and adjusts the correction position of the electromagnetic stirring mechanism 20 through the mobile system 10 to form a correction force for stirring the molten iron of the sintering machine trolley 60; wherein, the correction current parameters include correction current intensity and correction current frequency; it should be noted that after receiving the real-time data fed back by the monitoring system 40, the control system 50 continuously adjusts the current intensity I and the magnetic field intensity B according to the formula F=I×(L×B), so as to maintain or change the direction and speed of the molten iron flow; specifically, according to the feedback data, the current intensity is increased or decreased to adjust the magnetic field intensity, thereby changing the magnitude of the Lorentz force, which directly affects the iron The flow rate and direction of the liquid, for example, by increasing the current intensity or the magnetic field intensity, will increase the Lorentz force, forming a corrective force for stirring the molten iron in the sintering machine trolley 60, so that the flow of the molten iron is accelerated; and changing the frequency can affect the generation of eddy currents, further refining the control of the flow of the molten iron, especially when it is necessary to change the flow direction or adjust the flow pattern; at the same time, the position of the electromagnetic stirring mechanism 20 can also be adjusted by the mobile system 10 to affect the real-time data of the molten iron, that is, by changing the direction of the magnetic field (that is, adjusting the relative position of the electromagnetic coil 210 or the current direction), the direction of the Lorentz force can be changed, thereby affecting the flow direction of the molten iron; thereby, the adjustment of the stirring effect is formed by comprehensively forming the current intensity, current frequency, and the position of the electromagnetic stirring mechanism 20.

[0062] S5, repeat steps S2 to S4.

[0063] As you can see, this continuous monitoring and adjustment cycle ensures that the molten iron flows as expected, maintaining optimal flow even when production conditions change, enabling precise control of the direction and velocity of the molten iron flow, optimizing the sintering process and improving efficiency and product quality. The key to this approach is the ability to dynamically adjust the Lorentz force based on real-time monitoring data to adapt to the immediate needs of the production process.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
