Description

Technical Field

[0001] The utility model relates to the technical field of strip steel production, and particularly relates to a strip steel guiding water-cooled flat guide groove. Background Art

[0002] After the hot-rolled strip steel exits the finishing mill, it passes through the gauge guide groove, flat guide groove, and torsion guide groove to reach the three-way area at a speed of more than 12 meters per second. At this time, the temperature of the strip steel on the flat guide groove is about 900°C. In the long-term high-temperature environment, the bottom plate and side plates of the flat guide groove are deformed and cracked, affecting the quality of the strip steel product and the service life of the guide groove is short.

[0003] In the prior art, in the patent document with the publication number of CN221209392U, a waterproof interference flat guide groove for hot-rolled strip steel is proposed, which is used in the technical field of hot-rolled strip steel production. It includes baffles, a supporting mechanism, and a support frame; the baffles are arranged oppositely; the supporting mechanism is arranged between the baffles and includes a pipeline and a water passing port arranged between the pipelines. The pipeline is internally provided with circulating water and is connected to the water inlet pipe and the water outlet pipe at both ends; the support frame is arranged below the supporting mechanism and is connected to the baffle. The flat guide groove of the utility model is arranged at the corresponding position of the width gauge and / or thickness gauge, effectively eliminating the cooling water remaining on the surface of the strip steel when passing through the flat guide groove, and avoiding interfering with the detection signals of the width gauge and thickness gauge; adopting pipeline support and circulating water cooling to prevent it from being deformed by heat and decarburized and cracked; integrating multiple functions of guiding, supporting, cooling, and water removal, the overall structure is simple, convenient for maintenance, low in processing cost, and long in service life.

[0004] In order to solve the problem that although the flat guide groove in the prior art is provided with a cooling device, the cooling efficiency is low, the prior art is to directly discharge the cooling water remaining on the surface of the strip steel when passing through the flat guide groove through the water passing port, avoiding the interference of the cooling water on the detection signals of the width gauge and thickness gauge. However, there will still be a situation where the structure of the device is relatively complex and inconvenient to install during use, thereby reducing the practicality of the flat guide groove.

[0029] The following further describes the present utility model in detail with reference to the embodiments:

[0030] Embodiment 1

[0031] As Figures 1-5As shown in the figure, the utility model provides a strip guiding water-cooled flat guide groove, which includes a supporting unit 1; and a conveying unit 2 arranged on the outer surface of the supporting unit 1 for guiding. The supporting unit 1 includes a supporting component and a cooling component arranged on the outer surface of the supporting component. The conveying unit 2 includes a guide groove component arranged on the outer surface of the supporting unit 1 and a mounting component arranged on the outer surface of the guide groove component. The supporting component includes a support plate 11, and a welding leg 12 is welded on the upper surface of the support plate 11. The length of the welding leg 12 is 50 mm. The cooling component includes a first U-shaped steel groove 14, and the thickness of the first U-shaped steel groove 14 is 5 mm. The bottom surface of the first U-shaped steel groove 14 is fixedly connected to the upper surface of the welding leg 12. A water inlet pipe 13 is arranged on the outer surface of the first U-shaped steel groove 14, and the inner diameter of the water inlet pipe 13 is 50 mm. The outer diameter of the first U-shaped steel groove 14 is 910 mm. Multiple groups of the support plate 11 and the welding leg 12 are provided, and the support plate 11 and the welding leg 12 are evenly distributed on the bottom surface of the first U-shaped steel groove 14. An installation groove is formed on the outer surface of the first U-shaped steel groove 14. By the mutual cooperation of the support plate 11, the welding leg 12, the water inlet pipe 13 and the first U-shaped steel groove 14, it is convenient to cool the outer surface of the second U-shaped steel groove 21, so as to realize the rapid cooling of the second U-shaped steel groove 21, and further prevent the second U-shaped steel groove 21 from being deformed by heat, thereby increasing the service life of the strip guiding water-cooled flat guide groove. When the strip enters the inside of the second U-shaped steel groove 21, the temperature of the outer surface of the second U-shaped steel groove 21 will increase rapidly. Therefore, the water inlet pipe 13 is connected to the turbid circulating water pipe, and the inlet water pressure is adjusted to 0.45 MPa, so that the water enters the interlayer between the first U-shaped steel groove 14 and the second U-shaped steel groove 21. Since the top of the first U-shaped steel groove 14 is 50 mm lower than the top of the second U-shaped steel groove 21, when the water flows out from the outside of the first U-shaped steel groove 14, the overflow water can flow back to the swirling flow well through the slag flushing ditch, realizing the circulating cooling of the second U-shaped steel groove 21.

[0032] Embodiment 2

[0033] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the installation component includes a second U-shaped steel groove 21. A positioning hole 211 is formed on the outer surface of the second U-shaped steel groove 21. A fixing bolt 23 is threadedly connected to the inner wall of the positioning hole 211. The other end of the fixing bolt 23 is fixedly connected to the first U-shaped steel groove 14 through the fixing bolt 23. The outer diameter of the second U-shaped steel groove 21 is 720 mm. A conveying plate 22 is arranged on one side of the second U-shaped steel groove 21. The hypotenuse length of the conveying plate 22 is 150 mm. The top of the second U-shaped steel groove 21 is 50 mm higher than the upper surface of the first U-shaped steel groove 14. A spacing of 50 mm is formed between the first U-shaped steel groove 14 and the second U-shaped steel groove 21. The mutual cooperation of the second U-shaped steel groove 21, the conveying plate 22 and the fixing bolt 23 can conveniently fix the second U-shaped steel groove 21 on the outer surface of the first U-shaped steel groove 14, thereby increasing the practicability of the strip guiding water-cooled flat guide groove. When using the strip guiding water-cooled flat guide groove, first convey the strip into the interior of the second U-shaped steel groove 21, so as to cooperate with the support unit 1 to cool the strip, and further assist in guiding the strip.

[0034] Next, the working principle of the strip guiding water-cooled flat guide groove will be specifically described.

[0035] As Figures 1-5 shown, when using the strip guiding water-cooled flat guide groove, first convey the strip into the interior of the second U-shaped steel groove 21, so as to cooperate with the support unit 1 to cool the strip, and further assist in guiding the strip. When the strip enters the interior of the second U-shaped steel groove 21, the temperature on the outer surface of the second U-shaped steel groove 21 will increase rapidly. Thus, connect the turbid circulating water pipe in the water inlet pipe 13 and adjust the inlet water pressure to 0.45 MPa, so that water enters the interlayer between the first U-shaped steel groove 14 and the second U-shaped steel groove 21. Since the top of the first U-shaped steel groove 14 is 50 mm different from the top of the second U-shaped steel groove 21, when the water flows out from the outside of the first U-shaped steel groove 14, the overflowing water can flow back to the swirling flow well through the slag flushing ditch, realizing the circulating cooling of the second U-shaped steel groove 21.

[0036] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
