Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a spray pipe adjustment device for a casting machine. Background Technology

[0002] The capacity replacement project of the new No. 1 area of ​​Beiying Steel Plant was completed in June 2023. The production line is equipped with two 100t converters and two continuous casting machines. Since the production line was put into operation, the spray pipes of the secondary cooling chamber of the casting machines have been frequently replaced due to the lack of consideration for convenient replacement and maintenance in the design. The spray pipes were designed to be rigidly welded to the main water supply pipes. However, in actual production, due to various reasons such as water quality and process leakage, the spray pipes are frequently replaced due to deformation, blockage, and damage from handling leakage debris. After the spray frame is deformed, the spray angle of the nozzles changes accordingly, making it impossible to accurately spray onto the billet to achieve the cooling effect, and immediate replacement is required. Due to the humid and high-temperature working environment all year round, disassembly is extremely difficult, and replacing the "0" section spray pipe takes as long as 12 hours. Therefore, a spray pipe adjustment device for the casting machine is now provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spray pipe adjustment device for a casting machine. The process is simple, the structure is compact, the footprint is small, and the prefabrication speed is fast. It can ensure that the replacement time for the "0" segment spray water ring is reduced from 12 hours to 6 hours. The added angle adjustment component after the modification allows for arbitrary adjustment of the nozzle spray angle, enabling more precise control of the cooling billet position. Separate pipes are added to the air and water pipes, allowing for individual control of the flow rate of each medium. Therefore, the quality of the sprayed air and water mist is not affected by the instability of the mist caused by different damping in each flow pipe, making it easier to control. Furthermore, it can precisely control the cooling effect, ensuring the crystallization quality of the billet and overcoming the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A spray pipe adjustment device for a casting machine includes a fixed frame and a "0" segment water ring. The inner wall of the "0" segment water ring is equipped with nozzles at equal intervals. The outer walls of opposite sides of the "0" segment water ring are connected to rotating shafts via flanges. One end of the two rotating shafts is rotatably connected to the fixed frame via bearings. One of the rotating shafts is connected to an angle adjustment component. A water inlet connector and an air inlet connector are provided on one side of the "0" segment water ring.

[0006] As a further embodiment of this utility model: the angle adjustment assembly includes a worm gear connected to the end of one of the rotating shafts, and the worm gear is located on the outside of the fixed frame. A servo motor and a bearing seat are installed on the outer wall of the fixed frame. A worm is installed at the output end of the servo motor. One end of the worm is rotatably connected to the bearing seat through a bearing, and the worm meshes with the worm gear.

[0007] As a further embodiment of this utility model: the water inlet connector is connected to a water pipe, one end of which is connected to a water supply pipe; the air inlet connector is connected to an air pipe, one end of which is connected to an air compressor.

[0008] As a further embodiment of this utility model: a first solenoid valve is installed on the water pipe, and a second solenoid valve is installed on the air pipe. Both the first and second solenoid valves are externally connected to a control switch via wires.

[0009] As a further embodiment of this utility model: a first support hole and a second support hole are provided on one side of the fixed frame, the water pipe passes through the first support hole, and the air pipe passes through the second support hole.

[0011] As a further improvement of this utility model: the servo motor is provided with a protective shell, and the output end of the servo motor extends to the outside of the protective shell.

[0012] The beneficial effects of this utility model are as follows:

[0013] The process is simple, the structure is compact, the footprint is small, and the prefabrication speed is fast. It can ensure that the replacement time of the "0" segment spray water ring is shortened from 12 hours to 6 hours. The angle adjustment component added after the modification can arbitrarily change the nozzle spray angle, and more accurately control the position of the cooling billet. The air and water pipes are added separately, and the flow rate of each medium can be controlled individually.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A spray pipe adjustment device for a casting machine includes a fixed frame 1 and a "0" segment water ring 3. Nozzles 4 are installed at equal intervals on the inner wall of the "0" segment water ring 3. The outer walls of opposite sides of the "0" segment water ring 3 are connected to rotating shafts 11 through flanges. One end of the two rotating shafts 11 is rotatably connected to the fixed frame 1 through bearings. One of the rotating shafts 11 is connected to an angle adjustment component. A water inlet connector 5 and an air inlet connector 7 are provided on one side of the "0" segment water ring 3.

[0021] Water inlet connector 5 is connected to water pipe 6, one end of which is connected to a water supply pipe. Air inlet connector 7 is connected to air pipe 8, one end of which is connected to an air compressor.

[0022] A first solenoid valve 9 is installed on the water pipe 6, and a second solenoid valve 10 is installed on the air pipe 8. Both the first solenoid valve 9 and the second solenoid valve 10 are connected to a control switch via wires.

[0023] The fixed frame 1 has a first support hole 12 and a second support hole 13 on one side. The water pipe 6 passes through the first support hole 12 and the air pipe 8 passes through the second support hole 13.

[0025] The first solenoid valve 9 and the second solenoid valve 10 are controlled to open, so that compressed air and cooling water enter the water ring 3 in the "0" section and are sprayed out from the nozzle 4. By upgrading the original initial design of one air-water mixing pipe to two pipes, the compressed air and cooling water are controlled separately, which makes it easier to adjust the air-water mixing ratio and flow rate of each spray section and control the billet temperature more precisely.

A protective shell 14 is provided on the outside of the servo motor, and the output end of the servo motor extends to the outside of the protective shell 14.

[0028] By controlling the servo motor to drive the worm gear 16 to rotate, the worm gear 16 drives the worm wheel 15, the rotating shaft 11 and the "0" segment water ring 3 to rotate, thereby adjusting the angle of the "0" segment water ring 3 and more accurately controlling the position of the cooling billet.
