Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of converter slide plate hydraulic systems, in particular to a converter sliding tapping port hydraulic pipeline device. Background Art
[0002] The sliding plate of the converter's taphole is a crucial component in production, and its opening and closing is controlled by a hydraulic system. During the smelting process, the ambient temperature surrounding the hydraulic system piping is extremely high, placing a significant strain on the piping system. Due to the high temperature radiation and airflow from the converter, the piping is susceptible to thermal deformation, especially at the welds. Long-term exposure to high temperatures can cause fatigue and aging of the weld material at these welds, leading to weld debonding and pipeline leaks. This can also prevent the piping system's pressure from being effectively controlled, further increasing system operation and maintenance risks.
[0003] Frequent pipeline damage not only directly impacts production efficiency but also poses a series of safety risks. For example, pipeline leaks can lead to the loss of hydraulic oil, disrupting the normal operation of the converter. Furthermore, oil leaks can cause fires or other safety incidents. These safety issues not only threaten the safety of operators but can also cause further damage to production equipment.
[0004] Frequent failures and damage to piping systems often significantly reduce production efficiency. The time and resources required to repair and replace piping lead to production line downtime and financial losses. Furthermore, since the stability of the hydraulic system is directly related to the quality of converter operation, piping damage can affect the stability of the entire production process and product quality.

[0007] Preferably, the U-shaped bend is formed by processing the bend of an integral pipe.
[0008] Preferably, the U-shaped bend pipe has the same diameter as the first connecting pipe and is slightly smaller than the connected sleeve for nested connection.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1, as Figure 1-3 As shown, a hydraulic pipeline device for a sliding steel tapping port of a converter includes a U-shaped bend 1, a first connecting pipe 2, a second connecting pipe 3, an elbow 5, a sleeve 6, and a cooling box 7. One end of the U-shaped bend 1 is connected to the first connecting pipe 2 through the sleeve 6, the first connecting pipe 2 and the second connecting pipe 3 are connected through the elbow 5, the second connecting pipe 3 is connected to the hydraulic cylinder 4, and the second connecting pipe 3 passes through the cooling box 7. A first pipe clamp 8 and a second pipe clamp 9 are provided at both ends of the U-shaped bend 1, and a third pipe clamp 10 is provided on the second connecting pipe 3 between the sleeve 6 and the cooling box 7.
[0025] The U-bend 1 connects to the sleeve 6. As one of the main channels in the hydraulic piping system, the first connecting pipe 2 and the U-bend 1 have the same diameter, ensuring stable fluid flow throughout the pipeline and reducing pressure loss. The second connecting pipe 3 connects to the hydraulic cylinder 4 and passes through the cooling tank 7, serving as a transmission channel for coolant and hydraulic oil. The passage of the second connecting pipe 3 through the cooling tank 7 effectively reduces the temperature of the hydraulic oil in high-temperature environments, maintaining system stability and safety.
[0026] Hydraulic cylinder 4, the core actuator of the hydraulic system, controls the opening and closing of the sliding taphole. It is tightly connected to the pipeline, enabling precise motion control through an efficient hydraulic transmission system. Elbow 5 connects the first connecting pipe 2 and the second connecting pipe 3, changing the direction of the pipeline. This makes the pipeline layout more compact and protects against thermal expansion and contraction.
[0027] The sleeve 6 provides external protection, can effectively enhance the strength of the welding point, avoid the breakage of the pipeline under high temperature, and also has the function of preventing leakage.
[0028] The U-shaped piping design provides additional flexibility to cope with changes caused by thermal expansion and contraction. The structural design of the U-shaped piping should take into account the operating pressure and temperature of the hydraulic system to select the appropriate material and size to ensure long-term stable operation.
[0029] To ensure proper operation of the hydraulic system and improve oil cooling, it's essential to install a cooling tank 7 on the pipeline connecting one end of the hydraulic cylinder 4. This effectively lowers the oil temperature, preventing pipe rupture or system performance degradation caused by excessively high oil temperatures. The design of the cooling tank 7 should include an appropriate cooling device, such as a radiator or cooler, and ensure a good seal between the cooling tank and the pipeline system to maximize cooling effectiveness.
[0030] In order to further enhance the stability of the pipeline, pipe clamps are designed to fix the U-shaped bend 1, the first connecting pipe 2 and the second connecting pipe 3. Pipe clamps need to be set at both ends of the U-shaped pipeline to ensure its stability and reliability during system operation. The use of pipe clamps can effectively prevent the U-shaped bend 1, the first connecting pipe 2 and the second connecting pipe 3 from displacement during operation, and reduce the loosening of the pipeline caused by vibration or temperature changes. The material of the pipe clamp should have good high temperature resistance and corrosion resistance to adapt to the working environment in the hydraulic system. Through the fixation of the pipe clamp, the connection between the U-shaped bend 1, the first connecting pipe 2 and the second connecting pipe 3 can be more stable, thereby improving the reliability and safety of the entire system.
[0031] The following is a detailed description of the design of the above key components:
[0032] The U-shaped bend pipe 1 is formed by processing a bend in an integral pipe.
[0033] The U-shaped bend 1 and the first connecting pipe 2 have the same diameter, and are slightly smaller in diameter than the connected sleeve 6, which are nested together. The main purpose of the nesting design is to provide additional mechanical support, allowing the two pipes to be connected together more stably. A gap is left between the U-shaped bend 1 and the first connecting pipe 2. The U-shaped bend 1 and the first connecting pipe 2 are welded at both ends of the sleeve 6. The U-shaped bend 1 and the first connecting pipe 2 are welded at both ends of the sleeve 6 through a first welding point 11. The nesting design prevents the first welding point 11 at the connection from opening or failure due to long-term use.
[0034] The second connecting pipe 3 passes through the cooling box 7, and the through hole is welded to seal the cooling box 7. The cooling box 7 is connected to the inlet and outlet water pipes. The second connecting pipe 3 is welded through the second welding point 12 at the position where the cooling box 7 passes. The second welding point 12 is fully welded. This full welding method can ensure the overall strength of the pipeline at the connection and avoid separation or leakage caused by loose welding. Full welding not only increases the contact area of the welding area, but also improves the sealing of the pipeline connection, thereby reducing the risk of leakage in the system. During welding, attention should be paid to controlling the welding temperature and the selection of welding materials to ensure that the welding quality meets the standard requirements.
[0035] The other end of the U-shaped elbow 1 is connected to an external hydraulic power source.
[0036] Through the above measures, the stability and safety of the hydraulic pipeline system can be significantly improved, the failure rate of pipeline connections can be reduced, and the overall production efficiency can be improved.
[0037] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology and will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
