Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hydraulic cylinders, and in particular to a hydraulic cylinder in a high-temperature zone of a Steckel mill and a method of using the same. Background Art
[0002] The Steckel mill in a medium and heavy plate mill primarily produces wide and thin steel plates. The coiling furnace, a key piece of equipment, insulates the coiled steel plates during rolling, preventing them from cooling too quickly and affecting their performance. The coiling furnace uses mixed gas combustion, with temperatures reaching 1000°C. This heat radiates equipment near the coiling furnace, particularly the hydraulic cylinder, which uses hydraulic oil. This can lead to seal aging, leaks, and fires. Therefore, hydraulic cylinder modification is necessary. This application proposes a hydraulic cylinder for the high-temperature zone of a Steckel mill and its use method. Summary of the Invention
[0003] In response to the above technical problems, the present invention overcomes the shortcomings of the prior art and provides a hydraulic cylinder in the high-temperature zone of a Steckel mill and a method of using the same, which can significantly improve the performance of the hydraulic cylinder in the high-temperature zone, extend its service life and reduce the failure rate.
[0004] In the first aspect, the present invention provides a hydraulic cylinder for the high-temperature area of a Steckel mill, comprising a cylinder body and a water-cooling jacket connected to the outer wall of the cylinder body, wherein the water-cooling jacket is in the shape of a hollow cylinder and is wrapped around the outer wall of the cylinder body, and a flow channel is arranged in the water-cooling jacket, and a water inlet and a water outlet are respectively provided at both ends of the flow channel.
[0005] Furthermore, the water cooling jacket is connected to the outer side wall of the middle portion of the cylinder body.
[0006] Furthermore, the flow channel is spirally arranged in the water cooling jacket.
[0007] In the second aspect, the present invention also provides a method for using a hydraulic cylinder in the high-temperature area of a Steckel mill. The hydraulic cylinder is the hydraulic cylinder in the high-temperature area of a Steckel mill described in any scheme in the first aspect, and specifically includes introducing a cooling medium into the water inlet and discharging it from the water outlet through the flow channel.
[0008] The beneficial effects of the present invention are: The present invention provides a hydraulic cylinder for the high-temperature zone of a Steckel rolling mill and a method of using the same. By adding a water-cooling jacket and a joint to the outside of the hydraulic cylinder, a cooling medium is connected to cool the hydraulic cylinder body and the hydraulic oil. After the temperature of the hydraulic cylinder body and the hydraulic oil is reduced, the seal is protected at the same time. The present invention can significantly improve the performance of the hydraulic cylinder in the high-temperature zone, extend the service life and reduce the failure rate, ensure smooth production, and prevent accidents such as fire. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of the structure of a conventional hydraulic cylinder; Figure 2 Schematic diagram of the structure of the hydraulic cylinder in the high temperature area of the Steckel mill in a specific embodiment of the present invention; In the figure: 10, cylinder body; 20, water cooling jacket; 21, water inlet; 22, water outlet. DETAILED DESCRIPTION
[0010] The structure before transformation Figure 1 The equipment near the coiling furnace is exposed to high temperature radiation, especially the hydraulic cylinder, which uses hydraulic oil as the medium. The seal is prone to aging, leading to oil leakage and fire accidents, so the hydraulic cylinder needs to be modified.
[0011] like Figure 2 As shown, the high-temperature area hydraulic cylinder of the Steckel mill provided by the present invention specifically includes a cylinder body 10 and a water-cooling jacket 20 connected to the outer wall of the cylinder body 10. The water-cooling jacket 20 is hollow cylindrical and wrapped around the outer wall of the cylinder body 10, and a flow channel is arranged in the water-cooling jacket 20. A water inlet 21 and a water outlet 22 are respectively provided at both ends of the flow channel. The water-cooling jacket 20 is specifically wrapped around the middle outer wall of the cylinder body 10, and the flow channel is spirally evenly arranged in the water-cooling jacket 20.
[0012] The method for using the high-temperature hydraulic cylinder of the Steckel mill includes introducing a cooling medium into the water inlet 21 and discharging the cooling medium through the flow channel and out of the water outlet 22. The cooling medium may be circulating cooling water or other circulating coolant.
[0013] This invention primarily studies the hydraulic cylinder structure. By adding a water-cooling jacket and connector to the exterior of the cylinder, circulating water is introduced to cool the cylinder body and hydraulic oil. This lowers the temperature of the cylinder body and hydraulic oil, indirectly protecting the seal. This modification significantly improves the performance of hydraulic cylinders in high-temperature environments, extending their service life and reducing failure rates, ensuring smooth production and preventing accidents such as fires.
[0014] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
