Description

Technical Field

[0001] This invention relates to the field of furnace charge processing technology, and more specifically, to a furnace charge melting device with electromagnetic stirring. Background Technology

[0002] Electromagnetic stirring essentially enhances the movement of molten steel within the liquid phase cavity of the billet by using electromagnetic force induced in the cavity. This strengthens the convection, heat transfer, and mass transfer processes of the molten steel, thereby controlling the solidification process of the billet and playing a positive role in improving the quality of the billet. The convective movement of molten steel within the liquid phase cavity of the continuously cast billet has a significant impact on eliminating superheat, improving the solidification structure of the billet, and reducing component segregation.

[0003] Currently, when melting furnace charge, heating is the only method used. However, as the charge gradually melts at high temperatures, uneven heating can easily occur within the charge. While electronic stirring equipment can improve the melting efficiency of the charge inside the casting shell and circulate the molten liquid to prevent solidification, in practice, the excessively high temperature of the melted charge leads to heat leakage from the outside of the casting shell, resulting in excessively high surface temperatures. This not only causes significant heat loss but also environmental damage. Furthermore, the difficulty in absorbing and utilizing the heat results in low resource utilization and high operating costs for the melting equipment. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a furnace charge melting device with electromagnetic stirring. The technical problem to be solved by the present invention is that the furnace charge is too hot after melting, which leads to heat leakage on the outside of the casting shell. This results in the surface temperature of the casting shell being too high, which not only causes a large amount of heat leakage, but also easily damages the environment. At the same time, the melting device has low resource utilization and high operating cost because it is difficult to absorb and utilize the heat.

[0011] As a further aspect of the present invention: the flow guide shell is connected to one end of one ...

[0012] As a further embodiment of the present invention: the other end of the control valve is connected to the top of the liquid storage tank, a plurality of heat sinks are fixedly connected to the outside of the liquid storage tank, and the other side of the plurality of heat sinks is fixedly connected to the inner wall of the same heat conduction ring. The heat conduction ring is snapped into the inner wall of the cast shell, and the other end of the tee is fixedly connected to a second conduit. The other end of the second conduit is connected to the electromagnetic control device.

[0013] As a further embodiment of the present invention: both sides of the electromagnetic control device are fixedly connected to drain pipes, and the two drain pipes pass through two mounting seats and two sealing partitions and are connected to the flow guide shell.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting up a pressure device, an elastic device, a sealing device, and a piston device, allows the surface temperature of the casting shell to gradually overflow as the furnace charge inside the casting shell melts and the internal temperature rises. At this time, the guide shell absorbs a large amount of heat due to its contact with the casting shell, causing the liquid inside the guide shell to gradually evaporate as the temperature rises. Under the principle of thermal expansion and contraction, the pressure inside the guide shell will also gradually increase, causing the pressure regulating plate to be pushed upward by the pressure generated by the liquid evaporation and high temperature. This draws out the air between the sealing cylinder and the ground, creating a negative pressure state below the sealing cylinder, which has a fixing effect on the melting equipment. This prevents the casting shell from shifting due to the operation of the water pump assembly or electromagnetic control equipment during the operation of the melting equipment. Moreover, fixing the melting equipment can be achieved simply by absorbing the heat overflowing from the casting shell, thereby greatly reducing the resources required for the melting equipment and improving the resource utilization efficiency of the melting equipment.

[0018] 2. This invention, by setting up a heat-conducting ring, a liquid storage tank, a flow-guiding shell, and a casting shell, allows some heat to be transferred to the heat-conducting ring during use, and then to the liquid storage tank via the heat-conducting ring and heat sink. At this point, a water pump needs to be started to pump the liquid from inside the flow-guiding shell into the liquid storage tank. The liquid, after being heated, is then transported to the flow-guiding shell. This allows the melting equipment to quickly reduce the temperature of the casting shell during use by contacting the liquid storage tank with the casting shell, avoiding the need to wait for the casting shell to cool naturally for a long time after processing. The absorbed heat is recycled through the liquid storage tank and vaporization discharge, reducing the environmental damage caused by the melting equipment while improving the resource utilization rate of the melting equipment.

[0019] 3. By setting up a water pump assembly, a liquid storage tank, and a heat-conducting ring, the present invention requires the water pump assembly to be started when the melting equipment needs to be used again. The operation of the water pump assembly transfers the high-temperature liquid inside the guide shell to the liquid storage tank, thereby rapidly increasing the temperature inside the casting shell through external heating. This allows the melting equipment to store heat, preventing a large amount of heat loss after the casting equipment is shut down. This reduces heat loss and allows for heat absorption and utilization, improving the environmental performance of the melting equipment.

[0020] 4. By incorporating an electromagnetic stirrer, this invention requires the electromagnetic stirrer to be activated when processing the furnace charge through the casting shell. This enhances the movement of the molten furnace charge within the liquid phase cavity by utilizing the electromagnetic force induced within the casting shell. This allows the melting equipment to accelerate the movement of the furnace charge within the casting shell through the electromagnetic stirrer, preventing uneven melting and mixing of the furnace charge due to its accumulation, thus ensuring the effectiveness of the melting equipment.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, the present invention provides a furnace charge melting device with electromagnetic stirring, including a cast outer shell 1, a flow guiding outer shell 2 outside the cast outer shell 1, a liquid flow guiding channel 3 inside the flow guiding outer shell 2, and a sealing top plate 4 fixedly connected to the upper part of the inner wall of the liquid flow guiding channel 3. Because of the sealing top plate 4, when the liquid is heated and evaporates and the internal pressure of the high-temperature liquid flow guiding channel 3 increases, the sealing top plate 4 can seal the inside of the liquid flow guiding channel 3 to prevent pressure or liquid leakage. At the same time, it can protect the flow guiding outer shell 2.

[0030] The sealing top plate 4 is fixedly connected to the top of several elastic devices 5. The flow guide shell 2 is connected to one end of several first elbows 13 through several elastic positioning rings 12. The top of several first elbows 13 is connected to the bottom of several first conduits 14. The other end of several first conduits 14 is connected to the top of the same connecting pipe 16 through several second elbows 15. The bottom end of the connecting pipe 16 is fixedly connected to a tee 17. The bottom end of the tee 17 is fixedly connected to the control valve 19 through a connecting conduit 18. The connecting pipe 16 is connected to the control valve 19 through the tee 17 and the connecting conduit 18. Because the control valve 19 is provided, the control valve 19 can prevent the liquid inside the liquid storage tank 20 from flowing into the water pump assembly 241 along the second conduit 23. At the same time, the opening and closing of the control valve 19 can correspond to the drainage and water filling of the liquid storage tank 20, respectively, which improves the flexibility of the melting equipment and ensures the effect of the melting equipment.

[0031] The other end of the control valve 19 is connected to the top of the liquid storage tank 20. Several heat sinks 21 are fixedly connected to the outside of the liquid storage tank 20, and the other side of each heat sink 21 is fixedly connected to the inner wall of the same heat conduction ring 22. The heat conduction ring 22 is snapped into the inner wall of the casting shell 1. The other end of the tee 17 is fixedly connected to the second conduit 23. The other end of the second conduit 23 is connected to the electromagnetic control device 24. Because of the heat sinks 21 and the heat conduction ring 22, when the melting equipment needs to be used again, the water pump assembly 241 will transfer the high-temperature liquid inside the guide shell 2 to the liquid storage tank 20, thereby rapidly increasing the temperature inside the casting shell 1 through external heating. This allows the melting equipment to store heat, avoiding the loss of a large amount of heat after the casting equipment is shut down. This reduces heat loss and allows for the absorption and utilization of heat, improving the environmental protection effect of the melting equipment.

[0032] Furthermore, the bottom ends of several elastic devices 5 are fixedly connected to the top of pressure device 6, and the bottom of pressure device 6 is fixedly connected to the top of several piston devices 7. Both sides of electromagnetic control device 24 are fixedly connected to drain pipes 25, and the two drain pipes 25 pass through two mounting seats 26 and two sealing partitions 11 and are connected to the flow guide shell 2. Electromagnetic control device 24 is fixedly connected to the outside of casting shell 1. Because a water pump assembly 241 is provided, when it is necessary to recycle the liquid by means of liquid injection and liquid discharge, the collection and discharge of the liquid can be achieved simply by starting the water pump assembly 241, thereby ensuring the utilization rate of the heated liquid in the melting equipment and avoiding the situation where heat is continuously lost and difficult to utilize.

[0033] The electromagnetic control device 24 includes a water pump assembly 241. The bottom end of the second conduit 23 is connected to one end of the water pump assembly 241. The water pump assembly 241 is connected to the guide shell 2 through the drain pipe 25. An electromagnetic stirrer 242 is installed outside the water pump assembly 241. The electromagnetic stirrer 242 is fixedly connected to the front of the casting shell 1. Because of the electromagnetic stirrer 242, when processing the furnace charge through the casting shell 1, the electromagnetic stirrer 242 needs to be activated. In this way, the movement of the furnace charge in the liquid phase cavity is enhanced by the electromagnetic force induced in the casting shell 1. This allows the melting equipment to accelerate the movement of the furnace charge in the casting shell 1 through the electromagnetic stirrer 242, avoiding uneven melting and mixing of the furnace charge due to the accumulation of the furnace charge, and ensuring the effectiveness of the melting equipment.

[0034] The position of the piston device 7 corresponds to the position of the elastic device 5. The elastic device 5 includes a multi-section telescopic rod 51, and a return spring 52 is sleeved on the multi-section telescopic rod 51. The two ends of the multi-section telescopic rod 51 and the return spring 52 are fixedly connected to the top of the pressure device 6 and the bottom of the sealing top plate 4, respectively. Because of the elastic device 5, when the heat inside the guide shell 2 is lost and the liquid temperature drops, the air pressure inside the liquid guide channel 3 will gradually recover. At this time, the return spring 52 will squeeze the pressure regulating plate 61 and the piston sealing plate 72 to reset under its own elastic force, so that the pressure inside the sealing cylinder 81 is restored. At this time, the positioning suction cup 82 will loosen its adhesion to the ground, reducing the difficulty of moving the melting equipment and improving the flexibility of the melting equipment during use.

[0035] The piston device 7 is slidably connected inside the sealing device 8, and the sealing device 8 is fixedly connected to the lower part of the inner wall of the liquid guide channel 3. Several positioning mounting holes 10 are opened at the lower part of the inner wall of the liquid guide channel 3. The position of the positioning mounting holes 10 corresponds to the position of the sealing device 8. An elastic sealing ring 9 is sleeved inside the positioning mounting hole 10 and is fixedly connected to the outside of the sealing device 8. Because of the positioning mounting holes 10, the positioning suction cup 82 and the sealing cylinder 81 can contact the ground through the positioning mounting holes 10. Furthermore, the positioning mounting holes 10 allow the positioning suction cup 82 to be on the same plane as the bottom of the casting shell 1, ensuring the adsorption and fixation effect of the melting equipment on the ground.

[0036] The outer casing 2 is fixedly connected to two lugs 29 and a connecting seat 27. The bottom end of the connecting seat 27 is connected to the outer casing 2. A liquid injection valve 28 is provided above the connecting seat 27. Because of the liquid injection valve 28, the staff can replenish the liquid inside the outer casing 2 in a timely manner, so as to avoid the continuous evaporation and loss of liquid in the liquid guide tank 3, which would affect the use of the melting equipment and ensure the use effect of the melting equipment.

[0037] Two sealing baffles 11 are fixedly connected inside the liquid guide channel 3, and the back sides of the two sealing baffles 11 overlap with the front side of the pressure device 6. The pressure device 6 is slidably connected inside the liquid guide channel 3, and the shape of the pressure device 6 is adapted to the shape of the liquid guide channel 3. Several elastic positioning rings 12 are fixedly connected to the outside of the guide shell 2. Due to the presence of the pressure device 6 and the piston device 7, a negative pressure is formed below the sealing cylinder 81 when the internal temperature of the casting equipment increases, which has a fixing effect on the melting equipment and prevents the casting shell 1 from shifting due to the operation of the water pump assembly 241 or the electromagnetic control device 24 during the operation of the melting equipment. Moreover, the fixing of the melting equipment can be achieved by absorbing the heat overflowing from the casting shell 1, thereby greatly reducing the resources required by the melting equipment and improving the resource utilization efficiency of the melting equipment.

[0038] The pressure device 6 includes a pressure regulating plate 61, which is annular and its shape is adapted to the shape of the liquid guide channel 3. The upper part of the pressure regulating plate 61 is fixedly connected to the bottom end of several multi-section telescopic rods 51 and a return spring 52, and the lower part of the pressure regulating plate 61 is fixedly connected to the top end of several piston devices 7. A sealing edge 62 is fixedly connected to the outside of the pressure regulating plate 61. Because of the pressure regulating plate 61 and the sealing edge 62, when the pressure inside the liquid guide channel 3 increases, the sealing plate will gradually move upward with the pressure and steam compression, thereby ensuring the adjustment effect of the pressure extrusion rod 71 when the melting equipment is used. The sealing edge 62 can effectively prevent gas leakage.

[0039] The piston device 7 includes a pressure extrusion rod 71. The top end of the pressure extrusion rod 71 is fixedly connected to the bottom of the pressure regulating plate 61, and the bottom end of the pressure extrusion rod 71 is fixedly connected to a piston sealing plate 72. The piston sealing plate 72 is slidably connected inside the sealing device 8. The shape of the piston sealing plate 72 is adapted to the shape inside the sealing device 8. Because of the piston sealing plate 72, when the pressure extrusion rod 71 moves the piston sealing plate 72, the piston sealing plate 72 will be pulled out of the sealing cylinder 81 and is in contact with the ground. This makes the bottom of the sealing cylinder 81 a negative pressure state, thereby completing the fixing effect of the melting equipment and ensuring the stability of the melting equipment during use.

[0040] The sealing device 8 includes a sealing cylinder 81, with a positioning suction cup 82 fixedly connected to the lower part of the sealing cylinder 81. The positioning suction cup 82 is fixedly connected to the lower part of the inner wall of the liquid guide channel 3. The piston sealing plate 72 and the pressure extrusion rod 71 are slidably connected inside the sealing cylinder 81. The elastic sealing ring 9 is fixedly connected to the outside of the sealing cylinder 81. Because of the elastic sealing ring 9, when the sealing cylinder 81 is fixed to the ground by the positioning suction cup 82, the elastic sealing ring 9 can effectively fill the gap between the positioning suction cup 82 and the ground, preventing outside air from entering the sealing cylinder 81 along the gap between the positioning suction cup 82 and the ground, thus ensuring the fixing effect of the melting equipment.

[0041] Working principle of this invention:

[0042] When using this device, simply open the injection valve 28 to inject an appropriate amount of liquid into the guide shell 2, allowing the liquid to flow in the liquid guide channel 3. Then close the injection valve 28. When processing the furnace charge through the casting shell 1, the electromagnetic stirrer 242 needs to be started to enhance the movement of the furnace charge in the liquid phase cavity by means of the electromagnetic force induced in the casting shell 1.

[0043] As the furnace charge inside the casting shell 1 melts, the surface temperature of the casting shell 1 will gradually rise as the internal temperature increases. At this time, the guide shell 2 will absorb a large amount of heat due to its contact with the casting shell 1, causing the liquid inside the guide shell 2 to gradually evaporate as the temperature rises. Under the principle of thermal expansion and contraction, the pressure inside the guide shell 2 will also gradually increase, causing the pressure regulating plate 61 to be pushed and moved upward by the pressure generated by the liquid evaporation and high temperature. At this time, the pressure regulating plate 61 will drive the pressure squeezing rod 71 and the piston sealing plate 72 to slide inside the sealing cylinder 81, thereby drawing out the air between the sealing cylinder 81 and the ground, creating a negative pressure state below the sealing cylinder 81, which has a fixing effect on the melting equipment.

[0044] Due to the heat overflow during use of the cast outer shell 1, some heat will be transferred to the heat conduction ring 22 and then to the liquid storage tank 20 through the heat conduction ring 22 and the heat sink 21. At this time, the water pump needs to be started to discharge the liquid into the liquid storage tank 20 by drawing the liquid inside the guide shell 2. The temperature of the liquid transferred into the liquid storage tank 20 will gradually rise as it absorbs the high temperature. After the steam and pressure are discharged into the guide shell 2 through the first conduit 14, the liquid will be heated and then transported into the guide shell 2.

[0045] When the melting equipment needs to be used again, the water pump assembly 241 needs to be started. The operation of the water pump assembly 241 will transfer the high-temperature liquid inside the guide shell 2 to the liquid storage tank 20, thereby rapidly increasing the temperature inside the casting shell 1 through external heating, so that the melting equipment can store heat.
