[0035] See also Figures 1 to 2As shown, according to an embodiment of the present application, a steel plate insulation and cooling control system is provided, including an insulation slow cooling pit main body, a movable cover system, and a temperature control system; an insulation isolation retaining wall is arranged in the insulation slow cooling pit main body, and the insulation isolation retaining wall is used to divide the internal space of the insulation slow cooling pit main body into at least two slow cooling areas; the movable cover system includes at least two cover plates, and the cover plates are arranged corresponding to the slow cooling areas to open or close the corresponding slow cooling areas; the temperature control system includes a temperature measuring device, a cooling device, and a heating device, the temperature measuring device is used to obtain temperature information of each slow cooling area, and the cooling device and the heating device are used to adjust the temperature of the slow cooling area based on the temperature information obtained by the temperature measuring device.

[0036] By setting an insulating isolation retaining wall in the main body of the insulating slow cooling pit, the main body of the insulating slow cooling pit can be divided into at least two areas, which can realize zoning storage according to different batches and different time discharges. By setting at least two cover plates and setting the cover plates corresponding to the slow cooling areas, the corresponding slow cooling areas can be opened or closed, and when putting in or taking out a batch of steel plates, it is possible to avoid affecting the temperature of other batches of steel plates already in other slow cooling areas, thereby ensuring a good slow cooling effect for the steel plates. By setting a temperature control system, the temperature information of each slow cooling area can be obtained. By setting a cooling device and a heating device, the temperature of the corresponding slow cooling area can be adjusted based on the temperature information obtained by the temperature measuring device, thereby improving production quality. In addition, the slow cooling temperature can be adjusted according to different steel grades, thereby improving the flexibility of production organization.

[0037] Among them, the steel plate thermal insulation and cooling control system is a semi-underground pool structure.

[0038] Among them, the inner wall of the thermal insulation and slow cooling pit body is a vertically arranged wall structure.

[0039] Among them, 2 / 3 of the height of the main body of the thermal insulation and cooling pit is sunk below the ground, and 1 / 3 of the height is above the ground.

[0040] Among them, the movable cover system is set above the ground and located on the top of the thermal insulation and cooling pit body.

[0041] In this embodiment, two slow cooling areas and two cover plates are provided, and the two cover plates are respectively provided corresponding to the two slow cooling areas.

[0042] Each slow cooling area includes two storage spaces, and the two storage spaces can be connected. Setting up two storage spaces is more convenient for classified storage of steel plates.

[0043] Among them, such as Figure 1As shown, the thermal insulation isolation retaining wall 10 includes a first retaining wall 101 and a second retaining wall 102, which are arranged vertically. By providing the first retaining wall 101 and the second retaining wall 102, and by arranging the first retaining wall 101 and the second retaining wall 102 vertically, the thermal insulation slow cooling pit body can be divided into four slow cooling zones. The four slow cooling zones are divided into equal areas. One cover plate corresponds to two slow cooling zones, thereby achieving separate cooling control to a certain extent.

[0044] The first retaining wall 101 is arranged in a horizontal direction, and the second retaining wall 102 is arranged in a vertical direction.

[0045] It is understandable that each slow cooling area includes one or more storage spaces, and the specific number of storage spaces can be flexibly set according to the actual output of steel plates, which is not limited in this embodiment.

[0046] Among them, a pedestrian safety passage is also set in the thermal insulation isolation retaining wall 10, so that people have space to walk in the thermal insulation isolation retaining wall 10.

[0047] Among them, the temperature measuring device, cooling device and heating device are correspondingly arranged in each slow cooling area.

[0048] The movable cover system includes a driving device, which includes a transmission part 6 and a driving part 15. The driving part 15 is connected to the transmission part 6, and the transmission part 6 is connected to the cover plate, so that the driving part 15 drives the cover plate through the transmission part 6 to open or close the corresponding slow cooling area.

[0049] By providing the transmission part 6 and the driving part 15 and connecting the driving part and the transmission part, and connecting the transmission part 6 and the cover plate, the driving part 15 can drive the cover plate through the transmission part 6 to open or close the corresponding slow cooling area.

[0050] Among them, such as Figure 1 As shown, the driving part 15 is arranged in the middle position in the width direction of the heat-insulating and slow-cooling pit body.

[0051] In this embodiment, one driving part 15 drives two transmission parts 6 to move.

[0052] Pulleys 4 are provided on both sides of the cover plate, and a track 11 is provided on the main body of the thermal insulation slow cooling pit. The track 11 extends along the moving direction of the cover plate, and the pulley 4 is rollingly set on the track 11. The transmission part 6 also includes a transmission chain 13, which is connected to the pulley 4 to drive the pulley 4 to rotate so that the cover plate slides along the track 11.

[0053] By rolling the pulley 4 on the track 11 and connecting the transmission chain 13 to the pulley 4, the transmission chain 13 can drive the pulley 4 to rotate. The pulley 4 is set on the cover plate, and can then drive the cover plate to slide along the track 11, thereby achieving stable operation of the cover plate.

[0054] The moving direction of the cover plate is horizontal.

[0055] Wherein, pulleys 4 are arranged on both sides of the bottom of the cover plate.

[0056] Among them, tracks 11 are set on both sides of the length direction of the thermal insulation and slow cooling pit body, that is, double rows of tracks 11 are set, and the pulley 4 set at the bottom of the cover plate spans the double rows of tracks 11.

[0057] The transmission chain 13 is arranged corresponding to the track 11 .

[0058] Among them, anti-collision rails 7 are provided on the side walls and end walls of the main body of the thermal insulation and slow cooling pit, and the anti-collision rails 7 are arranged opposite to the ends of the tracks 11.

[0059] The main body of the thermal insulation and slow cooling pit includes an insulation layer 2 and a steel plate layer 1. The insulation layer 2 is located on the side of the steel plate layer 1 close to the slow cooling area. The bottom of the main body of the thermal insulation and slow cooling pit is evenly laid with heat-resistant cast steel pads.

[0060] By setting up the steel plate layer 1, the weight of the entire system can be supported and the stability of the entire structure can be enhanced; by setting up the insulation layer 2, the temperature in the insulation and slow cooling pit can be maintained to meet the insulation requirements; by setting up the heat-resistant cast steel pad 12, the steel placed in the insulation and slow cooling pit can be padded to enhance the heat dissipation effect.

[0061] Among them, stairs and safety passages 8 are set on both sides of the thermal insulation and slow cooling pit body to facilitate staff to enter the thermal insulation and slow cooling pit body.

[0062] The heat-resistant cast steel pad 12 is a rectangular parallelepiped structure.

[0063] Among them, square heat-resistant cast steel pads 12 are evenly arranged in the two slow cooling areas.

[0064] Among them, the steel plate layer 1 forms the outer layer around the main body of the thermal insulation slow cooling pit.

[0065] Among them, the thermal insulation layer 2 is arranged in the inner layer of the steel plate layer 1, forming an inner layer around the thermal insulation slow cooling pit body.

[0066] The temperature measuring device includes a temperature measuring head 9, which is arranged in each slow cooling area to obtain temperature information of each slow cooling area.

[0067] By providing the temperature measuring head 9 and placing the temperature measuring head 9 in each slow cooling area, the temperature information of each slow cooling area can be obtained.

[0068] Among them, the temperature measuring heads 9 are arranged at equal intervals on the inner wall of the slow cooling area.

[0069] Specifically, in one of the slow cooling areas, the temperature measuring heads 9 are evenly arranged on the inner wall of the slow cooling area. When the steel is placed in one of the slow cooling areas, there may be temperature differences in different areas of the steel itself. In order to avoid setting the temperature measuring heads 9 on only one side, which would result in inaccurate temperature measurements, the temperature measuring heads 9 are evenly arranged on the four inner walls of the slow cooling area, so that the temperature measuring heads 9 can more accurately measure the temperature of the slow cooling area.

[0070] Specifically, a controller is provided in one of the slow cooling areas to control the opening and closing of the temperature measuring head 9 .

[0071] Among them, a temperature display component is set outside the slow cooling area, and the temperature display component is connected to the temperature measuring head 9. The temperature obtained by the temperature measuring head 9 is transmitted through the temperature display component, and the temperature can also be displayed at the same time.

[0072] A temperature display component is correspondingly provided in each slow cooling area, and all slow cooling areas may correspond to a temperature display group capable of displaying all acquired temperatures.

[0073] The cooling device includes an air delivery pipe 18 and an air supply component 17. The air outlet end of the air delivery pipe 18 is arranged inside each slow cooling area, and the air supply component 17 is arranged outside the slow cooling area. The air delivery pipe 18 and the air supply component 17 are connected. When the temperature information obtained by the temperature measuring head 9 is higher than the preset temperature curve, the air supply component 17 can drive the cooling gas through the air delivery pipe 18 to the slow cooling area where the temperature is higher than the preset temperature curve.

[0074] By setting up an air delivery pipe 18 and an air supply component 17, and setting the air outlet end of the air delivery pipe 18 inside each slow cooling area, and setting the air supply component 17 outside the slow cooling area, when the temperature measuring head 9 obtains that the temperature of the corresponding slow cooling area is higher than the preset temperature curve, the cooling gas can be driven by the air supply component 17 and the air delivery pipe 18 to flow into the slow cooling area where the temperature is higher than the preset temperature curve, and then the inside of the slow cooling area is cooled, so that the temperature returns to the preset temperature curve, thereby ensuring a good slow cooling effect.

[0075] The preset temperature curve is preset in the temperature control system. Different steel plates may correspond to different preset temperature curves. The preset temperature curve is a curve showing the relationship between temperature and time. In the curve, as time increases, the temperature of the steel plate decreases.

[0076] Among them, the temperature control system can be a part of the control system 16 of the steel plate insulation and cooling control system. The control system 16 can be set on the outside of the insulation and cooling pit body and close to the insulation and cooling pit body for easy operation.

[0077] In this embodiment, the main body of the thermal insulation slow cooling pit is divided into two slow cooling areas. In one of the slow cooling areas, the air delivery pipes 18 are evenly arranged on the four walls inside the slow cooling area, that is, at least one row of air delivery pipes 18 needs to be set on one side of the wall, and at least four rows of air delivery pipes 18 are set in one slow cooling area. At the same time, four air supply components 17 need to be set in one slow cooling area. The four air supply components 17 are set outside the slow cooling area, that is, outside the main body of the thermal insulation slow cooling pit. The four air supply components 17 are respectively connected to the at least four rows of air delivery pipes 18. The operation of the cooling device is controlled by setting a controller, that is, the four air supply components 17 and at least four rows of air delivery pipes 18 in a slow cooling area are controlled by a controller until the temperature is cooled to the preset temperature curve, so that the steel plate is cooled according to the preset temperature curve.

[0078] By arranging air conveying pipes 18 on the four inner walls of a slow cooling area and correspondingly arranging four air supply components 17 outside the slow cooling area, the temperature in a slow cooling area can be cooled evenly, so that the steel in the slow cooling area is evenly exposed to cooling gas on all four sides, avoiding the situation where the air conveying pipe is arranged on one or both sides of the inner wall, resulting in uneven overall temperature of the steel, where the temperature of the side exposed to cooling gas drops faster and is lower, while the temperature of the side without the air conveying pipe drops slower and is higher, thereby causing uneven slow cooling of the steel in this area.

[0079] The heating device includes a burner 19 and a gas delivery pipe 14. The gas delivery pipe 14 extends into each slow cooling area. The burner 19 is arranged on the gas delivery pipe 14 and is located in each slow cooling area. When the temperature information obtained by the temperature measuring head 9 is lower than the preset temperature curve, the gas delivery pipe 14 is used to pass gas into the slow cooling area where the temperature is lower than the preset temperature curve, and the burner 19 is used to ignite the gas.

[0080] By arranging a burner 19 and a gas delivery pipe 14 in the slow cooling area, when the temperature measuring head 9 obtains that the temperature of the corresponding slow cooling area is lower than the preset temperature curve, gas can be delivered to the slow cooling area where the temperature is lower than the preset temperature curve through the gas delivery pipe 14, and ignited through the burner 19, thereby increasing the temperature in the slow cooling area where the temperature is lower than the preset temperature curve.

[0081] In this embodiment, the main body of the thermal insulation slow cooling pit is divided into two major slow cooling areas. In one of the slow cooling areas, the gas delivery pipes 14 and the burners 19 are evenly arranged on the four walls inside the slow cooling area, that is, at least one row of gas delivery pipes 14 needs to be set on one side of the wall, and at least four rows of gas delivery pipes 14 are set in one slow cooling area. At the same time, at least four rows of burners 19 need to be set accordingly in one slow cooling area. The burners 19 are set on the gas delivery pipes 14. The operation of the heating device is controlled by setting a controller, that is, at least four rows of gas delivery pipes 14 and at least four rows of burners 19 in a slow cooling area are controlled by a controller to heat the temperature of the slow cooling area until the temperature is heated to a preset temperature curve, so that the steel plate is heated according to the preset temperature curve.

[0082] By setting a controller to control at least four rows of gas delivery pipes 14 and at least four rows of burners 19 in a slow cooling area, the temperature in a slow cooling area can be evenly heated, so that the steel in the slow cooling area is evenly exposed to heat flow on all four sides, avoiding the situation where the gas delivery pipes 14 are set on one or both sides of the inner wall and the overall temperature of the steel is uneven, the temperature of the side exposed to the heat flow rises faster and is higher, while the temperature of the side without the gas delivery pipe 14 rises slower and is lower than the temperature of the steel on the side with the gas delivery pipe 14, thereby causing the temperature of the steel in this area to be uneven.

[0083] The cover plate includes a first cover plate 3 and a second cover plate 5. The first cover plate 3 and the second cover plate 5 are arranged horizontally. The first cover plate 3 and the second cover plate 5 are staggered in the vertical direction so that the first cover plate 3 and the second cover plate 5 can slide relative to each other in the horizontal direction to open or close the corresponding slow cooling area.

[0084] By setting the first cover plate 3 and the second cover plate 5, and staggering the first cover plate 3 and the second cover plate 5 in the vertical direction, the first cover plate 3 and the second cover plate 5 can slide relative to each other in the horizontal direction, avoiding interference between the first cover plate 3 and the second cover plate 5 during movement, and the corresponding slow cooling areas can be automatically opened at the same time or automatically opened separately, solving the problem that the traditional thermal insulation slow cooling facility cover cannot be opened automatically and some covers cannot be opened due to the integral structure, thereby improving production efficiency.

[0085] Among them, such as Figure 2 As shown, the first cover plate 3 is arranged higher than the second cover plate 5 .

[0086] Among them, such as Figure 2 As shown, the first cover plate 3 is arranged on the left side of the insulation and slow cooling pit body, and can cover the insulation and slow cooling area on the left side. The second cover plate 5 is arranged on the right side of the insulation and slow cooling pit body, and can cover the insulation and slow cooling area on the right side.

[0087] A first accommodating space is provided below the first cover plate 3 , and the second cover plate 5 can slide laterally into the first accommodating space to open the second cover plate 5 .

[0088] A second accommodating space is provided above the second cover plate 5 , and the first cover plate 3 can slide laterally into the second accommodating space to open the first cover plate 3 .

[0089] The first cover plate 3 and the second cover plate 5 can be opened separately or simultaneously.

[0090] The opening and closing of the first cover plate 3 and the second cover plate 5 can be controlled electrically or manually.

[0091] like Figure 3 As shown, another aspect of this embodiment provides a method for heat preservation and cooling control of a steel plate, the method comprising:

[0092] Step S101: driving at least one cover plate to move and opening a corresponding slow cooling area;

[0093] Step S201: placing the steel plate into the corresponding slow cooling area;

[0094] Step S301: driving at least one cover plate to move and close the corresponding slow cooling area;

[0095] Step S401: obtaining temperature information of the slow cooling area through a temperature measuring device;

[0096] Step S501: When the acquired temperature information is higher than the preset temperature curve, the cooling device is controlled to operate to cool the steel plate in the corresponding slow cooling area; when the acquired temperature information is lower than the preset temperature curve, the heating device is controlled to operate to heat the steel plate in the corresponding slow cooling area.

[0097] The driving unit 15 drives the cover plate to open or close the corresponding slow cooling area through the transmission unit 6 .

[0098] The horizontal axis of the preset temperature curve is time, and the vertical axis is temperature.

[0099] The preset temperature curve is a quadratic function curve.

[0100] When the time-temperature function curve in the slow cooling area is different from the preset time-temperature curve, the temperature in the slow cooling area needs to be adjusted to the preset time-temperature curve.

[0101] Among them, when the temperature in the slow cooling area is higher than the preset temperature curve, the temperature in the slow cooling area needs to be cooled down. When the temperature in the slow cooling area is lower than the preset temperature curve, the temperature in the slow cooling area needs to be heated up.

[0102] Step S401: further includes:

[0103] Step S4011: obtaining temperature information of each slow cooling area through a temperature measuring device;

[0104] Step S4012: comparing the acquired temperature information of each slow cooling area with a preset temperature curve;

[0105] Step S4013: Based on the comparison result, the steel plates in the slow cooling area with temperature information higher than the preset temperature curve are cooled respectively, and the steel plates in the slow cooling area with temperature information lower than the preset temperature curve are heated respectively.

[0106] The preset temperature curve is preset in the temperature control system. Different steel plates may correspond to different preset temperature curves. The preset temperature curve is a curve showing the relationship between temperature and time. In the curve, as time increases, the temperature of the steel plate decreases.

[0107] In step S4012, the temperature information is compared with the temperature at the corresponding point in the preset temperature curve to obtain a comparison result. Specifically, the temperature information is compared with the temperature at the corresponding time point in the preset temperature curve.

[0108] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

The above are merely preferred embodiments of the present application.
