Detailed Embodiments
[0026] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0027] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.
[0028] As Figure 1 、 Figure 2 and Figure 3 shown, a melting device for pouring high-temperature cast steel parts provided by an embodiment of the present invention includes:
[0029] A base 1, on which multiple groups of supports 24 are installed. Among them, two groups of supports 24 are rotatably connected to a fixed seat 9. A rotating seat 10 is rotatably installed on the fixed seat 9. The rotating seat 10 is driven by a second motor 23. At least three groups of telescopic rods 11 are rotatably installed on the rotating seat 10. A support rod 31 is slidably arranged inside the telescopic rod 11. A first electromagnet 29 is fixedly arranged in the inner cavity of the telescopic rod 11. A third spring 30 is arranged between the first electromagnet 29 and the support rod 31. A magnetic block is fixedly arranged at one end of the support rod 31 close to the third spring 30. A first pressure sensor is fixedly installed on the first electromagnet 29. The other end of the support rod 31 away from the third spring 30 is rotatably connected to a crucible 20. The support rod 31 is horizontally arranged;
[0030] An induction coil 13 is installed on the fixed seat 9, and the induction coil 13 is arranged outside the crucible 20.
[0031] In an embodiment of the present invention, during smelting, raw materials are put into the crucible 20, the induction coil 13 is started, and the raw materials inside the crucible 20 are heated by the induction coil 13. The second motor 23 is started, and the rotating base 10 is driven to rotate by the second motor 23. The rotating base 10 drives the crucible 20 to rotate. Since the crucible 20 is in a rotating state, it can ensure that the internal raw materials are heated more evenly. Due to the uneven distribution of the raw materials inside the crucible 20, the center of gravity of the crucible 20 and the raw materials as a whole is likely to be non - coincident with the rotation axis of the rotating base 10, which will lead to instability of the whole device and vibration. To solve this problem, the support rod 31 arranged inside the telescopic rod 11 supports the crucible 20 from at least three directions, thereby adjusting the relative position relationship between the crucible 20 and the rotating base 10, making the center of gravity of the crucible 20 and the raw materials as a whole coincide with the rotation axis of the rotating base 10 to ensure the stability of its rotation. The swing angle of the telescopic rod 11 is limited by setting a stop block, so as to achieve the purpose of restricting the movement range of the crucible 20. At the beginning of heating, it rotates at a lower speed to facilitate the center - of - gravity adjustment of the crucible 20. After heating for a period of time, part of the raw materials melt. Due to the skin effect, the induction coil 13 has a more obvious heating effect on the raw materials located at the edge. Then, the rotation speed is increased to promote the raw materials to approach the edge of the crucible 20, so as to enhance the heating effect on the unmelted raw materials and promote the rapid melting of the raw materials, improving the melting efficiency.
[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, the induction coil 13 is a spiral structure. A plurality of sets of side brackets 15 are fixedly installed on the fixed seat 9. Guide columns 16 are fixedly arranged on the side brackets 15. Two sets of sleeves are slidably arranged on the guide columns 16. The two sets of sleeves are respectively fixedly connected with a first transmission rod 18 and a second transmission rod 19. The two ends of the induction coil 13 are respectively fixedly connected with a first connection ring 12 and a second connection ring 14. The first transmission rod 18 and the second transmission rod 19 are respectively fixedly connected with the first connection ring 12 and the second connection ring 14. A first spring 17 is also sleeved on the guide column 16. The first spring 17 is located between the two sets of sleeves. Magnets are fixedly installed on the sleeves. A set of second electromagnets 32 are fixedly installed at both ends of the guide column 16.
[0033] In this embodiment, for different raw materials, the densities of the raw materials in the solid phase and the liquid phase are different. Therefore, when partial melting of the raw materials occurs, the unmelted raw materials may float on the molten pool or sink to the bottom of the molten pool due to their own densities. If the position of the induction coil 13 is not adjusted, the induction coil 13 will continue to heat the already melted material, resulting in the overflow of the temperature of the local material, while some materials have not melted yet. At this time, the moving direction of the induction coil is determined according to the initial density of the raw material. When the density of the solid-phase raw material is greater than that of the liquid-phase raw material, it means that the unmelted raw material will sink to the bottom. At this time, the second electromagnet 32 located above the first transmission rod 18 is activated, and the first transmission rod 18 is pushed downward by the second electromagnet 32. The magnetic force is transmitted through the magnetic block, and multiple groups of first transmission rods 18 move downward, driving the first connecting ring 12 to approach the second connecting ring 14. Then, the induction coil 13 located between the first connecting ring 12 and the second connecting ring 14 is compressed downward, thus concentrating at the bottom of the crucible 20. Similarly, when the density of the solid-phase raw material is less than that of the liquid-phase raw material, it means that the unmelted raw material will float, and the second electromagnet 32 located below the second transmission rod 19 is activated, and the second transmission rod 19 is driven by the second electromagnet 32 to approach the first transmission rod 18, thereby compressing the induction coil 13 upward. When the induction coil 13 is compressed, the magnetic field strength will increase, so as to improve the heating effect of the local area and accelerate the melting speed of the unmelted raw material.
[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, the melting device for casting high-temperature cast steel parts further includes a sealing cover 21 and a mounting plate 4. The mounting plate 4 is fixed above the base 1 through a top mounting bracket 2. A first motor 3 is fixedly installed on the mounting plate 4. A threaded rod 6 is fixedly connected to the output shaft of the first motor 3. A plurality of guide rods 5 are also fixedly installed on the mounting plate 4. A guide plate 8 is slidably connected to the guide rods 5. The guide plate 8 is provided with a plurality of guide sleeves, and the guide rods 5 are located inside the guide sleeves. A connecting rod 7 is fixedly connected to the guide plate 8. A threaded hole is provided in the core of the connecting rod 7, and the threaded rod 6 is located inside the threaded hole. A plurality of telescopic sleeves 27 are fixedly installed at one end of the connecting rod 7 away from the first motor 3. A guide block is slidably arranged inside the telescopic sleeve 27. A fourth spring is arranged in the inner cavity of the telescopic sleeve 27. A limiting block 28 is fixedly connected to the guide block. The cross-sectional edge of the limiting block 28 is arched. The sealing cover 21 is connected to the crucible 20 by threads. A limiting ring 25 is fixedly arranged on the top of the sealing cover 21, and a plurality of limiting grooves 26 are arranged on the limiting ring 25.
[0035] In this embodiment, in the existing steelmaking process, the open melting method is mainly adopted. Since there is no sealing, heat loss will occur, and surface oxidation will also occur. By setting the sealing cover 21, heat loss can be reduced and the oxidation amount can be decreased. During melting, the crucible 20 is controlled to move to the central position of the rotating seat 10, and the first motor 3 is started. The first motor 3 drives the threaded rod 6 to rotate, thereby driving the connecting rod 7 to lift and lower along the guide rod 5. The connecting rod 7 drives the telescopic sleeve ......
[0036] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in [relevant figures], as a preferred embodiment of the present invention, a discharge push rod 22 is rotatably installed on the base 1, and one end of the discharge push rod 22 away from the base 1 is rotatably connected to the fixed seat 9; the number of the discharge push rods 22 is two groups, and the two groups of discharge push rods 22 are arranged in parallel.
[0037] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in [relevant figures], as a preferred embodiment of the present invention, there are three groups of supports 24, two groups of supports 24 are rotatably connected to the fixed seat 9, and the remaining one group of supports 24 is used to support the fixed seat 9.
[0038] In this embodiment, by providing a discharging push rod 22, when discharging, the fixed seat 9 can be pushed to flip relative to the base 1, so as to pour out the molten material inside the crucible 20. During this process, the crucible 20 can be moved to the edge of the rotating seat 10, and the induction coil 13 can be compressed downward to facilitate the pouring of the material.
[0039] In one embodiment of the present invention, a melting method for casting high-temperature cast steel parts is provided, which is applied to the melting device for casting high-temperature cast steel parts as described above. The method includes:
[0040] Place the raw materials into the crucible 20, control the rotation of the crucible 20, and heat the crucible through the induction coil 13.
[0041] In this step, the induction coil 13 is in a fully unfolded state, so as to heat all the raw materials inside the crucible 20 synchronously. The crucible 20 rotates at a relatively low speed, such as 20 revolutions per minute. At this time, the center of gravity is unstable and it is not suitable to rotate at a high speed.
[0042] During the rotation of the crucible 20, obtain the pressure data of the pressure sensor, and calculate the position of the axis where the center of gravity of the crucible 20 and the raw materials as a whole is located according to the pressure data.
[0043] Control the movement of the crucible 20 until the center of gravity of the crucible 20 and the raw materials as a whole is located on the rotating shaft of the second motor 23, and dynamically adjust the position of the crucible 20 during the heating process.
[0044] In this step, while the crucible 20 is rotating, the pressure data of the pressure sensors is acquired. There are three groups of pressure sensors, and the three groups of support rods 31 are evenly distributed around the crucible 20. Due to the unstable center of gravity, during the rotation, the crucible 20 will shift to one side. Then, the pressure data detected by the pressure sensors corresponding to the support rods 31 in the corresponding direction will increase, which is proportional to the compression amount of the third spring 30. According to the detection values of the three groups of pressure sensors, the position of the center of gravity of the raw material and the crucible 20 as a whole can be determined. Control the crucible 20 to stop rotating. At this time, start the first electromagnet 29, and push or attract the magnetic blocks on the support rods 31 through the first electromagnet 29 to control the support rods 31 to pull or push the crucible 20, thereby changing the position of the crucible 20 to ensure that the center of gravity of the crucible 20 and the raw material as a whole is located on the rotation axis of the second motor 23. After the adjustment is completed, rotate again. If the center of gravity still does not coincide, make fine adjustments until the condition that the center of gravity of the crucible 20 and the raw material as a whole is located on the rotation axis of the second motor 23 is satisfied. When the condition is met, the pressure data detected by each pressure sensor will show a stable state. When the pressure value changes by no more than ±3%, it is determined that the center of gravity of the crucible 20 and the raw material as a whole is located on the rotation axis of the second motor 23. If the position of the raw material changes during the heating process, the center of gravity will also change slightly. Then, during the rotation, adjust the magnetic force of the corresponding first electromagnet 29 according to the pressure values detected by each pressure sensor. When the crucible 20 shifts to one side, the resultant force on the crucible 20 is balanced, that is, the resultant force of the three groups of support rods 31 on the crucible 20 is equal in magnitude and opposite in direction to the centrifugal force on the crucible 20. Based on this, the direction of the center of gravity of the crucible 20 and the raw material as a whole can be determined, and by controlling the crucible 20 to move in the reverse direction, the center of gravity can be driven back to the rotation axis of the rotating base 10.
[0045] During the rotation of the crucible 20, calculate the melting degree of the raw material based on the change in the rotation speed of the crucible 20, and control the position and distribution density of the induction coil 13 to perform tracking heating on the unmelted raw material.
[0046] In this step, when the raw materials have not melted yet, the raw materials and the crucible 20 can be regarded as a whole. When the raw materials melt, relative movement will occur between the raw materials, and the resistance to the relative movement is determined by the viscous resistance of the molten raw materials. As the temperature rises, the viscous resistance of the raw materials gradually decreases. This means that if the output torque of the motor is constant, assuming that the crucible 20 containing solid raw materials with a mass of m is accelerated to an angular velocity of V0 in a time of T0, and the crucible 20 containing liquid raw materials (in a molten state) with the same mass is accelerated to an angular velocity of V1 in a time of T1, then T1 is less than T0. This is because the molten raw materials can slide relative to each other. Therefore, by testing the acceleration time of this material at different melting processes, that is, by counting the time required to accelerate the crucible 20 containing the raw materials to a specified angular velocity at each stage, a raw material melting curve can be constructed. The horizontal axis of the melting curve is the time value, and the vertical axis is the melting process. Then, during the actual melting process, the current crucible 20 is tested, and it is accelerated from 0 to the specified angular velocity. According to the time used, the raw material melting curve is queried to determine the current melting process;
[0047] According to the melting process, the position of the remaining unmelted raw materials is further determined, so as to control the induction coil 13 to compress in the corresponding direction, and the effect of enhanced heating can be achieved. And during this process, the rotation speed of the crucible 20 can be appropriately increased to drive the unmelted raw materials close to the inner wall of the crucible 20, so as to accelerate the melting speed and improve the melting efficiency.
[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
