Description

Technical Field

[0001] This utility model relates to the field of steel plate manufacturing, and in particular to a hot-rolled steel plate stacking and cooling device. Background Technology

[0002] Hot-rolled steel plates are steel products produced through hot rolling processes and are widely used in construction, machinery manufacturing, automobiles, shipbuilding, bridges, and many other fields. Hot-rolled steel plates have a wide range of strengths, good toughness, good corrosion resistance, and good processing performance. Among them, medium and heavy plates are widely used in building structures, machinery manufacturing, pressure vessels, and other fields. The production process of hot-rolled steel plates mainly includes heating, rolling, straightening, stacking cooling, and shearing finishing. Among them, hot-rolled steel plate stacking cooling refers to a process of stacking rolled steel plates together for natural or controlled cooling.

[0003] In existing technologies, hot-rolled steel plates stacked vertically have a faster cooling rate at the top and bottom layers compared to the plates in the middle. This uneven cooling rate can lead to fluctuations in the steel plate's performance. Since one side of the top and bottom steel plates is exposed, the excessively fast cooling rate can cause problems such as cracks, bending, and deformation on the surface or inside of some steel plates, reducing the stacking cooling effect and the quality of the steel plates. Utility Model Content

[0004] The purpose of this invention is to provide a hot-rolled steel plate stacking and cooling device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A hot-rolled steel plate stacking and cooling device includes a stacking and cooling barrel. Several support plates are fixed at equal intervals inside the stacking and cooling barrel. Two limiting rods are slidably connected to the side of each support plate near the steel plate. A steel plate is placed between each pair of limiting rods. An adjusting spring is fixed to the side of each limiting rod away from the steel plate. The support plates are arranged in a ring inside the stacking and cooling barrel. A ring-shaped heat preservation channel is formed between the support plates and the inner wall of the stacking and cooling barrel. A barrel cover is inserted into the top of the stacking and cooling barrel. A vent pipe is fixed to the bottom of the barrel cover. A fan is fixed to the top of the vent pipe.

[0007] Preferably, the lid has handles fixed on both sides, and a round hole is opened in the middle of the lid for the ventilation pipe to pass through.

[0008] Preferably, the outside of the vent pipe is provided with several air inlet slots, and the outside of the stack-cooled barrel is provided with several exhaust holes.

[0009] Preferably, a slider is fixed on the side of the limiting rod near the support plate, and a first sliding groove that cooperates with the slider is opened on the side of the support plate near the limiting rod. The end of the adjusting spring away from the limiting rod is fixedly connected to the side wall of the first sliding groove.

[0010] Preferably, both the slider and the first groove have a T-shaped cross-section.

[0011] Preferably, the limiting rod is arc-shaped on the side near the steel plate, and a support rod is fixed at the bottom of the limiting rod near the vent pipe. Several second sliding grooves that cooperate with the support rod are opened on the bottom of the inner side of the stacking cooler.

[0012] Preferably, four limiting blocks are fixed to the bottom of the inner side of the stack-cooled barrel, and the four limiting blocks are connected to the vent pipe.

[0013] The beneficial effects compared with the existing technology are as follows: the steel plates are clamped and limited by two limiting rods of several support plates distributed in a ring, so that several steel plates are connected end to end in a ring array. This avoids the difference in cooling rate between the top and bottom layers and the middle layer of steel plates caused by vertical stacking. Two adjusting springs limit the position of steel plates of different thicknesses by limiting rods. After the fan introduces external air, it diffuses radially with the vent pipe as the center, promoting the flow of heat inside the stack cooling barrel, achieving uniform cooling, and improving the stack cooling effect and the quality of steel plates.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-9 As shown, a hot-rolled steel plate stacking and cooling device includes a stacking and cooling barrel 1.

[0029] In this embodiment: several support plates 5 are fixed at equal intervals inside the stacking cooler hopper 1. Two limiting rods 6 are slidably connected to the side of each support plate 5 closest to the steel plate 15. A steel plate 15 is provided between every two limiting rods 6. Adjusting springs 7 are fixed to the side of each limiting rod 6 furthest from the steel plate 15. A slider 10 is fixed to the side of each limiting rod 6 closest to the support plate 5. A first groove 11 is formed on the side of each support plate 5 closest to the limiting rod 6, cooperating with the slider 10. The end of the adjusting spring 7 furthest from the limiting rod 6 is connected to the first groove 11. The sidewalls are fixedly connected. The cross-sections of the slider 10 and the first slide groove 11 are both T-shaped. The side of the limiting rod 6 near the steel plate 15 is arc-shaped. A support rod 12 is fixed to the bottom of the limiting rod 6 near the vent pipe 3. Several second slide grooves 13 that cooperate with the support rods 12 are opened on the bottom of the inner side of the stacking cooler 1. Several support plates 5 are arranged in a ring inside the stacking cooler 1. The several support plates 5 and the inner wall of the stacking cooler 1 form a ring-shaped heat preservation channel. Several steel plates 15 that need to be cooled after rolling are placed into the several support plates in sequence. The two limiting rods 6 of plate 5 define the position between them, so that several steel plates 15 are connected end to end in a circular array. This avoids the cooling rate difference between the top and bottom layers and the middle steel plates 15 due to the vertical stacking method. When a steel plate 15 is inserted between the two limiting rods 6, the two limiting rods 6 are pressed by the steel plate 15 and slide away from the steel plate 15. During the sliding process, the two limiting rods 6 drive the corresponding two sliders 10 to slide in the first slide groove 11. The cooperation between the T-shaped sliders 10 and the first slide groove 11 prevents the limiting rods 6 from falling off. During the sliding process, the two limiting rods 6 drive the corresponding two support rods 12 to slide in the second slide groove 13. The support rods 12 support the end of the limiting rod 6 near the vent pipe 3 to prevent it from drooping. The sliding of the two limiting rods 6 compresses the two adjusting springs 7 located in the first slide groove 11 and fixedly connected to its side wall. The two adjusting springs 7 rebound and react on the corresponding two limiting rods 6, so that the two limiting rods 6 clamp and limit the position of steel plates 15 of different thicknesses.

[0030] In this embodiment: a lid 2 is inserted into the top of the stack-cooled drum 1, a vent pipe 3 is fixed to the bottom of the lid 2, a fan 4 is fixed to the top of the vent pipe 3, four limiting blocks 14 are fixed to the bottom of the inner side of the stack-cooled drum 1, and the four limiting blocks 14 are inserted into the vent pipe 3. Handles are fixed to both sides of the lid 2, a round hole for the vent pipe 3 to pass through is opened in the middle of the lid 2, several air inlet slots 9 are opened on the outer side of the vent pipe 3, and several exhaust holes 8 are opened on the outer side of the stack-cooled drum 1. After several steel plates 15 are placed, the lid 2 is inserted into the top of the stack-cooled drum 1 through the two handles to achieve heat preservation of several steel plates 15 and avoid rapid cooling affecting quality. The vent pipe 3 is driven into the stack-cooled drum 1 through the lid 2. The air is inserted between four limiting blocks 14. After the fan 4 introduces external air into the ventilation pipe 3, it enters between several steel plates 15 through several air inlet slots 9. The air diffuses radially around the ventilation pipe 3, promoting the flow of heat inside the stack-cooled barrel 1 and achieving uniform cooling. Several annularly distributed support plates 5 form annular channels with the inner wall of the stack-cooled barrel 1. As the air flows from the ventilation pipe 3 to the inner wall of the stack-cooled barrel 1, it carries away the heat of the steel plates. The hot air gathers in the annular channels to form a heat preservation effect, preventing the steel plates from cooling rapidly. Finally, it is gradually discharged from several exhaust holes 8. The speed at which the fan 4 introduces air and carries away heat indirectly controls the cooling speed of several steel plates 15.

[0031] Working principle: Several rolled steel plates 15, which require cooling, are sequentially placed between two limiting rods 6 of several support plates 5 to define their positions. This ensures that the steel plates 15 are arranged in a circular array, end to end, preventing different cooling rates between the top and bottom layers and the middle layers due to vertical stacking. When a steel plate 15 is inserted between two limiting rods 6, the two limiting rods 6 are pressed away from the steel plate 15 and slide away from it. During this sliding process, the two limiting rods 6 drive the corresponding two sliders 10 to slide within the first slide groove 11. The T-shaped sliders 10 and the first slide groove 11 work together to prevent the limiting rods 6 from falling off. During this sliding process, the two limiting rods 6 drive the corresponding two support rods 12 to slide within the second slide groove 13. The support rods 12 support the end of the limiting rod 6 near the vent pipe 3 to prevent it from sagging. The sliding of the two limiting rods 6 compresses two adjusting springs 7 located within the first slide groove 11 and fixedly connected to its side wall. The compression and rebound of the two adjusting springs 7 act on the corresponding two limiting rods 6, which clamp and limit the position of the steel plates 15 of different thicknesses. After several steel plates 15 are placed, the bucket lid 2 is inserted into the top of the stack-cooled bucket 1 through the two handles to keep the steel plates 15 warm and prevent rapid cooling from affecting the quality. The bucket lid 2 drives the vent pipe 3 into the stack-cooled bucket 1 and inserts it between the four limiting blocks 14. The fan 4 introduces external air into the vent pipe 3 and then into the space between the steel plates 15 through several air inlet slots 9. The air diffuses radially around the vent pipe 3, promoting the flow of heat inside the stack-cooled bucket 1 and achieving uniform cooling. The air flows into the annular heat-insulating channel formed between the support plates 5 and the inner wall of the stack-cooled bucket 1 and is gradually discharged from several exhaust holes 8. The speed at which the fan 4 introduces air and carries away heat indirectly controls the cooling speed of the steel plates 15. After cooling is complete, the steel plates 15 can be removed one by one.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
