Description

Technical Field

[0001] This application relates to the field of steel production technology, specifically to a ladle inverting device. Background Technology

[0002] In the iron and steel metallurgical process, the ladle, as a container for holding and transporting molten steel and undergoing secondary metallurgy, directly affects the stable control of molten steel temperature and the timing of processes within the steelmaking plant. Ladle management is crucial for energy conservation, emission reduction, efficiency improvement, and steel quality. However, traditional methods suffer from problems such as incomplete cleaning of impurities at the ladle nozzle and unstable self-flow rate. These problems not only affect production efficiency but may also lead to a decline in product quality. For example, impurities in the ladle nozzle can cause slag backflow, thus affecting the purity of the molten steel. Furthermore, the ladle's self-opening rate is also a key factor affecting production efficiency. Our company ensures that impurities and slag in the ladle nozzle are fully discharged, improving the ladle's self-flow rate. Since ladles are generally heavy, they are typically lifted using a gantry crane and turned using another machine, which is not only cumbersome but also makes it difficult to completely remove impurities. Therefore, finding a stable and efficient way to turn the ladle is a crucial consideration. Utility Model Content

[0003] The purpose of this application is to provide a ladle inversion device to ensure stable ladle rotation.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] This application discloses a ladle inverting device, which includes...

[0006] A first tilting frame is rotatably mounted, and a drive frame is provided on the first tilting frame;

[0007] A fixed second tilting frame is provided, and a positioning part is provided between the second tilting frame and the first tilting frame; a rotating arm is provided on the side of the first tilting frame away from the second tilting frame;

[0008] The drive unit is connected to the rotating arm and drives the first tilting frame to rotate, so that the drive frame drives the ladle.

[0009] The positioning component is movable and can switch positions to limit the first tilting frame.

[0010] In a further embodiment of this application, the drive frame includes a bracket and a slot box, with one end of the bracket fixedly connected to the first tilting frame and the other end fixedly connected to the slot box.

[0011] In a further embodiment of this application, the positioning unit includes a first positioning seat and a second positioning seat. The second positioning seat is fixedly connected to the second tilting frame, the first positioning seat is fixed to the ground, and the steel ladle is in positioning contact with the first positioning seat and the second positioning seat.

[0012] In a further embodiment, the first positioning seat and the second positioning seat are provided with equal-height limiting grooves on their opposing surfaces.

[0013] In a further embodiment of this application, a reduction gearbox is also connected between the drive unit and the rotating arm.

[0014] In a further embodiment of this application, the rotating arm is mounted via a rotary support.

[0015] In a further embodiment, the positioning component includes a positioning cylinder and a positioning pin. The positioning cylinder is fixed inside the rotary support, and the output end of the positioning cylinder is fixedly connected to the positioning pin.

[0017] The beneficial effects of this application are as follows:

[0018] In actual production, the ladle is equipped with rotating shafts on both sides, and lifting lugs are rotatably installed at the ends of the rotating shafts. The positioning part designed in this application can effectively support the lifting lugs of the ladle. At the same time, the legs of the ladle are in contact with the drive frame.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0024] like Figure 1 and Figure 2 As shown, this embodiment discloses a ladle 100 inverting device, which includes a first tilting frame 6 rotatably mounted, a second tilting frame 61 fixedly mounted, a drive unit (a common existing structure, so it is omitted from the drawing), and a positioning component that is movable. The first tilting frame 6 is provided with a drive frame 8; a positioning unit is provided between the second tilting frame 61 and the first tilting frame 6; a rotating arm 11 is provided on the side of the first tilting frame 6 away from the second tilting frame 61; the drive unit is connected to the rotating arm 11, and the drive unit drives the first tilting frame 6 to rotate, so that the drive frame 8 drives the ladle 100; the positioning component can switch positions to contact the first tilting frame 6, wherein the first tilting frame 6 and the second tilting frame 61 are set at the same height to improve aesthetics.

[0025] It should be noted here that, as shown in the attached document... Figure 2 As shown, in this embodiment, the upper walls of the ladle 100 are symmetrically fixed with rotating shafts on both sides. The ends of the rotating shafts away from the ladle 100 are rotatably mounted with lifting lugs 101. The lifting lugs 101 are designed to facilitate lifting with lifting equipment. The bottom of the ladle 100 is provided with multiple legs 102. The number of legs 102 is sufficient to stably support the ladle 100.

[0026] In use, the lifting lug 101 is placed on the positioning part by the gantry crane and hook, and the wrapping leg 102 contacts the drive frame 8. The drive part drives the rotating arm 11 to rotate the first tilting frame 6, so that the ladle 100 can rotate around its own axis in a large arc. This allows for the quick and efficient discharge of debris and sludge from the water inlet, ensuring the ladle 100's gravity flow rate.

[0027] As attached Figure 1As shown, in this embodiment, the positioning part includes a first positioning seat 7 and a second positioning seat 71. The second positioning seat 71 is fixedly connected to the second tilting frame 61. The first positioning seat 7 is fixed to the ground by a bracket (omitted in the figure for easy observation of the structure). The ladle 100 is in positioning contact with the first positioning seat 7 and the second positioning seat 71. In a further embodiment, in order to achieve a quick positioning function, the designers proposed that equal-height limiting grooves 10 be provided on the opposite surfaces of the first positioning seat 7 and the second positioning seat 71. The shape of these limiting grooves 10 matches that of the lifting lugs 101 on the ladle 100. In actual production, the distance between the positioning seat and the bottom of the drive frame 8 is equal to or slightly less than the distance between the lifting lugs 101 and the ladle legs 102.

[0028] In some embodiments, the first positioning seat 7 is rotatably installed at the center of the first tilting frame 6, and the second positioning seat 71 is fixed at the center of the second tilting frame 61. The two positioning seats are at the same height, and the two positioning seats are also provided with limit grooves 10 at the same height. Since the second tilting frame 61 is fixed, when the equipment is in operation, the two positioning seats are stationary, and the first tilting frame 6 rotates normally relative to the first positioning seat 7.

[0029] The drive frame 8 here includes a bracket and a slot box. One end of the bracket is fixedly connected to the first tilting frame 6, and the other end is fixedly connected to the slot box. In use, one or more ladle legs 102 fall into the groove of the slot box. The ladle legs 102 are squeezed by the groove wall to drive the ladle 100.

[0030] Here is a brief description of the drive unit. The drive unit can be configured as a motor. The driving gear on the motor meshes with the driven gear on the rotating arm 11 to transmit power. In this embodiment, a reduction gearbox 1 is added. The output end of the motor is connected to the input end of the reduction gearbox 1. The rotating arm 11 is connected to the output shaft of the reduction gearbox 1 through a coupling 2. With the intervention of the reduction gearbox 1, the power input is ensured to be smooth, and the stability of the ladle 100 rotation is further improved.

[0031] In this embodiment, the rotating arm 11 is installed via the slewing bracket 3, and the second tilting frame 61 is fixed to the ground via the mounting base 9, which reduces the risk during the rotation of the ladle 100. A sunken working area is set on the ground between the first tilting frame 6 and the second tilting frame 61 to lower the overall center of gravity of the equipment, since the temperature of the molten metal in the ladle 100 is extremely high.

[0032] Observe again Figure 1 In this embodiment, the positioning component includes a positioning cylinder 4 and a positioning pin 5. The positioning cylinder 4 is fixed in the rotary bracket 3 by a mounting block. The output end of the positioning cylinder 4 is fixedly connected to the positioning pin 5. The positioning pin 5 is intermittently inserted into the positioning hole on the first tilting frame 6. After the ladle 100 rotates into position, it is positioned by the positioning pin 5, which reduces the heavy burden on other connecting parts in the device and improves its service life.

[0033] The processed ladle 100 is placed on the inverting device and stabilized. The ladle 100 is then rotated 180 degrees and held for 3 minutes to ensure that impurities and slag in the nozzle are fully discharged. After inverting, check the area around the nozzle seat bricks for any remaining slag. If any remains, clean them by blowing oxygen through an oxygen pipe. After the ladle 100 is refilled with molten steel, a gravity flow rate test is performed, and the actual measured gravity flow rate reaches 99.87%.

[0034] This technical solution significantly improves the self-flow rate of the ladle 100 by using an inverted operation, reducing the frequency of oxygen-assisted casting. It reduces production delays and resource waste caused by low self-flow rates, and lowers the consumption of guiding sand and refractory materials. It maintains the cleanliness of the nozzle, reduces slag backflow, and improves the purity of the molten steel. It also reduces slag erosion of the nozzle, extending the service life of the ladle 100. This method is simple to operate, easy to implement on existing production lines, and requires no additional equipment.
