Description

Technical Field

[0001] The present application belongs to the technical field of steel rolling, and more specifically, to a heat preservation cover and steel cooling equipment. Background Art

[0002] In the production process of high-speed wire, the final rolling temperature is generally above 830°C. The wire after final rolling is usually formed into a coil by a spinning machine, and the wire is laid flat and stacked on the high-speed wire air-cooled roller in circles. The high-speed wire air-cooled roller is used to cool the wire to room temperature and move the wire to the coiling station for coiling operation.

[0003] In the related art, the fan under the high-speed wire air-cooling roller usually blows air from bottom to top to reduce the temperature of the wire to room temperature. Since the wires on the high-speed wire air-cooling roller are stacked together in circles, when the fan blows upward, the part of the wire facing the fan dissipates heat faster, while the stacked part dissipates heat slower, resulting in uneven cooling of the wire, which is prone to the appearance of unwanted metal structures (such as widmanstatten, troostite, etc.), affecting the quality of the wire. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a heat preservation cover and a steel cooling device to solve the technical problem of uneven wire cooling existing in the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a heat preservation cover, which is arranged at the opening of the high-speed wire air-cooling roller, and the high-speed wire air-cooling roller includes two side plates and a plurality of rollers located between the two side plates and arranged along the transmission direction, and the rollers are used to convey the wire, and the heat preservation cover includes:

[0006] Cold air storage room, which is equipped with cold air outlets, which are used to blow out or inhale cold air into the high-speed air-cooled roller table;

[0007] The hot air storage room is provided with a hot air outlet, which is used to blow out or inhale hot air into the high-line air-cooled roller.

[0008] The thermal insulation cover provided in the embodiment of the present application can blow out or inhale cold air and hot air respectively to the high-line air-cooling roller through the cold air storage chamber and the hot air storage chamber inside the thermal insulation cover, so as to adjust the temperature of the wire on the high-line air-cooling roller, make the air-cooling process of the wire more uniform, improve the uniformity of wire cooling, reduce the quality problems caused by uneven metal structure, and thus improve the quality and production efficiency of the wire.

[0009] In some embodiments, the cold air outlet and the hot air outlet are located on one side or both sides of the wire, and the cold air outlet and the hot air outlet blow out or inhale cold air or hot air from one side or both sides of the wire toward the opposite side of the wire.

[0010] By adopting the above technical solution, the cold air outlet and the hot air outlet blow out or inhale cold air or hot air from one side or both sides of the wire, so that the cold air and hot air can cover the entire surface of the wire, thereby achieving comprehensive cooling or heating of the wire and ensuring uniform overall temperature distribution; in addition, since the cold air outlet and the hot air outlet are located on the side of the wire, they will not directly blow on the surface of the wire, which can reduce the interference of the wind flow on the surface of the wire, and help improve the surface quality of the wire.

[0011] In some embodiments, the cold air outlet and / or hot air outlet is located on the side of the wire away from the roller, and the cold air outlet and hot air outlet blow out or inhale cold air or hot air from the side of the wire away from the roller toward the roller.

[0012] By adopting the above technical solution, cold air or hot air can be blown directly to the surface of the wire from the cold air outlet or the hot air outlet, which can achieve rapid adjustment of the temperature of the wire, can more effectively promote the heat dissipation or heating of the wire, help to speed up the cooling or heating speed of the wire, so that the temperature of the wire quickly reaches the required temperature, and help to improve the quality of the wire.

[0013] In some embodiments, the thermal insulation cover also includes an air duct, which is arranged in the hot air storage chamber, and one end of the air duct is connected to the cold air storage chamber, and the other end of the air duct is located on the side of the wire away from the roller, the cold air outlet is located at the connection between the air duct and the cold air storage chamber, and the hot air outlet is located at the connection between the air duct and the hot air storage chamber, and valves for controlling the inflow or outflow of cold air or hot air are provided at the cold air outlet and the hot air outlet.

[0014] By adopting the above technical solution, the air duct is directly connected to the cold air storage chamber and the hot air storage chamber, and the cold air or hot air can be directly delivered to the side of the wire away from the roller, which can reduce the loss of energy in the transmission process and improve the energy utilization efficiency; by controlling the valves at the cold air outlet and the hot air outlet, the inflow or outflow of cold air or hot air can be accurately adjusted, which can effectively control the temperature of the wire to ensure that it is within the ideal processing temperature range.

[0015] In some embodiments, the heat preservation cover is connected to the side plate, and the heat preservation cover has a accommodating cavity. A partition plate is provided in the accommodating cavity, and the partition plate is used to separate the accommodating cavity into a cold air storage chamber and a hot air storage chamber.

[0016] By adopting the above technical scheme, the partition plate divides the accommodating chamber of the insulation cover into a cold air storage chamber and a hot air storage chamber, which can realize the effective utilization of the space inside the insulation cover, and at the same time can effectively isolate the cold air and the hot air, reduce the mutual interference between the cold air and the hot air, and ensure that the storage chambers corresponding to the cold air and the hot air respectively maintain stable temperature and pressure, which helps to improve the stability and controllability of the wire during the processing process, improve the processing efficiency of the wire, and ensure product quality.

[0017] In some embodiments, the thermal insulation cover also includes a guide member, which has a first end and a second end that are relatively arranged, the first end is connected to the cold air storage chamber or the hot air storage chamber, and the second end is located on the side of the wire away from the roller, and the guide member is used to guide the cold air or hot air to the surface of the wire.

[0018] By adopting the above technical solution, the guide member can accurately and stably guide the cold air or hot air to the surface of the wire, which can reduce the energy loss caused by air flow and reduce energy waste, while making the temperature of the entire surface of the wire evenly lower or higher, which helps to improve the uniformity and consistency of wire processing; in addition, the guide member can more accurately control the heating or cooling effect of the cold air or hot air on the wire, which helps to flexibly adjust the temperature according to actual processing requirements, thereby improving the controllability and accuracy of wire processing.

[0019] In some embodiments, a dimension of the first end is smaller than a dimension of the second end.

[0020] By adopting the above technical solution, the size of the first end is smaller than that of the second end, so that the side of the guide close to the wire is trumpet-shaped, which helps to distribute the cold air or hot air more evenly, so that the cold air or hot air forms a more uniform heating or cooling effect on the surface of the wire, which helps to improve the quality and consistency of the processed products; the airflow can be gradually accelerated in the process from the second end to the first end, which can increase the speed of the airflow, and help to improve the transmission efficiency of the cold air or hot air.

[0021] In some embodiments, there are multiple cold air vents and / or hot air vents, and the multiple cold air vents and / or hot air vents are spaced apart on the partition plate.

[0022] By adopting the above technical solution, multiple cold air vents and / or hot air vents are spaced apart on the partition plate, so that the cold air or hot air can be evenly distributed across the width of the wire, which helps to achieve uniform heating or cooling of the wire surface and improve the quality and consistency of wire processing; multiple cold air vents and / or hot air vents can make it possible to heat or cool different parts of the wire at the same time during the processing process, which can shorten the processing time and improve production efficiency.

[0025] In some embodiments, the steel cooling equipment further includes a plurality of groups of circulating fans, which are arranged at intervals on both sides of the high-line air-cooling roller.

[0041] See also Figures 1 to 6 The embodiment of the present application proposes a heat preservation cover 10, which includes a cold air storage chamber 11 and a hot air storage chamber 12.

[0042] The heat preservation cover 10 is arranged to cover the opening of the high-speed wire air-cooling roller 20. The high-speed wire air-cooling roller 20 includes two side plates 21 and a plurality of rollers 22 disposed between the two side plates 21 and along the transmission direction of the wire 30. The two side plates 21 and the plurality of rollers 22 enclose the above-mentioned opening. The rollers 22 are used to transport the wire 30 from one end of the high-speed wire air-cooling roller 20 to the other end.

[0043] The cold air storage chamber 11 is provided with a cold air outlet 111 , and the cold air outlet 111 is used to blow out or inhale cold air into the high-line air-cooling roller table 20 .

[0044] The cold air storage chamber 11 is a cavity structure made of ordinary steel (eg, Q235B or Q195). The cold air outlet 111 is a through hole opened on the cold air storage chamber 11, and cold air flows into or flows out of the cold air storage chamber 11 through the cold air outlet 111.

[0045] The cold air storage chamber 11 has a certain pressure (generally 4MPa to 8MPa) and is provided with a conveying pressure-powered air pump. When it is necessary to blow cold air to the wire 30, the conveying pressure-powered air pump is operated to convey the cold air in the cold air storage chamber 11 from the cold air outlet 111 to the high-line air-cooled roller 20 to cool the wire 30 on the roller 22. When it is necessary to suck cold air from the wire 30, the conveying pressure-powered air pump is operated to suck the cold air in the high-line air-cooled roller 20 into the cold air storage chamber 11.

[0046] The hot air storage chamber 12 is provided with a hot air outlet 121 , and the hot air outlet 121 is used to blow out or inhale hot air into the high-line air-cooling roller table 20 .

[0047] Cold wind and hot wind are two definitions based on temperature, and the temperature of cold wind is lower than that of hot wind.

[0048] The hot air storage chamber 12 is a cavity structure with a heat-resistant steel plate as a frame, two layers of heat-insulating organic glass installed on the frame, and fire-resistant wool filled between the two layers of heat-insulating organic glass. The hot air outlet 121 is a through hole opened on the hot air storage chamber 12, and hot air flows into or flows out of the hot air storage chamber 12 through the hot air outlet 121.

[0049] The hot air storage chamber 12 has a certain pressure (generally 4MPa to 8MPa) and is provided with a conveying pressure-powered hot air pump. When it is necessary to blow hot air to the wire 30, the conveying pressure-powered hot air pump is operated to convey the hot air in the hot air storage chamber 12 from the hot air outlet 121 to the high-line air-cooled roller 20 to heat the wire 30 on the roller 22. When it is necessary to absorb hot air from the wire 30, the conveying pressure-powered hot air pump is operated to absorb the hot air in the high-line air-cooled roller 20 into the hot air storage chamber 12.

[0050] The thermal insulation cover 10 provided in the embodiment of the present application can blow out or inhale cold air and hot air respectively to the high-line air-cooling roller 20 through the cold air storage chamber 11 and the hot air storage chamber 12 inside the thermal insulation cover 10, so as to adjust the temperature of the wire 30 on the high-line air-cooling roller 20, so as to make the air-cooling process of the wire 30 more uniform, improve the uniformity of cooling of the wire 30, reduce the quality problems caused by uneven metal structure, and thus improve the quality and production efficiency of the wire 30.

[0051] like Figures 1 to 4 As shown, in some embodiments, the cold air outlet 111 and the hot air outlet 121 are located on one side or both sides of the wire 30 , and the cold air outlet 111 and the hot air outlet 121 blow out or inhale cold air or hot air from one side or both sides of the wire 30 toward the opposite side of the wire 30 .

[0052] For example, Figure 2 As shown, the cold air outlet 111 and the hot air outlet 121 are both located on the same side of the wire 30, the cold air storage chamber 11 is connected to the opening of the high-line air-cooled roller 20 through the cold air duct 131, and the cold air outlet 111 is located at the connection between the cold air duct 131 and the high-line air-cooled roller 20; the hot air storage chamber 12 is connected to the opening of the high-line air-cooled roller 20 through the hot air duct 132, and the hot air outlet 121 is located at the connection between the hot air duct 132 and the high-line air-cooled roller 20. When blowing cold air to the wire 30, the cold air in the cold air storage chamber 11 is transported to the cold air outlet 111 through the cold air duct 131, and blown out from the cold air outlet 111 toward the opposite side of the wire 30; when absorbing cold air from the high-line air-cooled roller 20, the cold air at the opening of the high-line air-cooled roller 20 enters the cold air duct 131 from the cold air outlet 111, and enters the cold air storage chamber 11 along the cold air duct 131. When blowing hot air toward the wire 30, the hot air from the hot air storage chamber 12 is transported to the hot air outlet 121 through the hot air duct 132, and is blown out from the hot air outlet 121 toward the opposite side of the wire 30; when absorbing hot air from the high-line air-cooling roller 20, the hot air at the opening of the high-line air-cooling roller 20 enters the hot air duct 132 from the hot air outlet 121, and enters the hot air storage chamber 12 along the hot air duct 132.

[0053] For example, Figure 3As shown, the cold air outlet 111 and the hot air outlet 121 are both located on both sides of the wire 30, wherein the cold air outlet 111 is located on the right side of the wire 30, and the hot air outlet 121 is located on the left side of the wire 30. The cold air storage chamber 11 is connected to the opening of the high-speed wire air-cooled roller 20 through the cold air duct 131, and the cold air outlet 111 is located at the connection between the cold air duct 131 and the high-speed wire air-cooled roller 20; the hot air storage chamber 12 is connected to the opening of the high-speed wire air-cooled roller 20 through the hot air duct 132, and the hot air outlet 121 is located at the connection between the hot air duct 132 and the high-speed wire air-cooled roller 20. When blowing cold air to the wire 30, the cold air in the cold air storage chamber 11 is transported to the cold air outlet 111 through the cold air duct 131, and blown out from the cold air outlet 111 toward the left side of the wire 30; when absorbing cold air from the high-line air-cooling roller 20, the cold air at the opening of the high-line air-cooling roller 20 enters the cold air duct 131 from the cold air outlet 111, and enters the cold air storage chamber 11 along the cold air duct 131. When blowing hot air to the wire 30, the hot air in the hot air storage chamber 12 is transported to the hot air outlet 121 through the hot air duct 132, and blown out from the hot air outlet 121 toward the right side of the wire 30; when absorbing hot air from the high-line air-cooling roller 20, the hot air at the opening of the high-line air-cooling roller 20 enters the hot air duct 132 from the hot air outlet 121, and enters the hot air storage chamber 12 along the hot air duct 132.

[0054] For example, Figure 4 As shown, the cold air outlet 111 is located on both sides of the wire 30, and the hot air outlet 121 is located on both sides of the wire 30. The cold air storage chamber 11 is connected to the opening of the high-speed wire air-cooled roller 20 through the cold air pipes 131 on the left and right sides, and the cold air outlets 111 on both sides are respectively located at the connection between the cold air pipes 131 on both sides and the high-speed wire air-cooled roller 20; the hot air storage chamber 12 is connected to the opening of the high-speed wire air-cooled roller 20 through the hot air pipes 132 on both sides, and the hot air outlets 121 on both sides are respectively located at the connection between the hot air pipes 132 on both sides and the high-speed wire air-cooled roller 20. When blowing cold air toward the wire 30, the cold air in the cold air storage chamber 11 is transported to the cold air outlets 111 on both sides through the cold air ducts 131 on both sides, and is blown out toward the opposite sides of the wire 30 from the cold air outlets 111 on both sides; when absorbing cold air from the high-line air-cooling roller 20, the cold air at the opening of the high-line air-cooling roller 20 enters the cold air ducts 131 on both sides from the cold air outlets 111 on both sides, and enters the cold air storage chamber 11 along the cold air ducts 131 on both sides. When blowing hot air toward the wire 30, the hot air in the hot air storage chamber 12 is transported to the hot air outlets 121 on both sides through the hot air ducts 132 on both sides, and is blown out toward the opposite sides of the wire 30 from the hot air outlets 121 on both sides; when absorbing hot air from the high-line air-cooling roller 20, the hot air at the opening of the high-line air-cooling roller 20 enters the hot air ducts 132 on both sides from the hot air outlets 121 on both sides, and enters the hot air storage chamber 12 along the hot air ducts 132 on both sides.

[0055] By adopting the above technical solution, the cold air outlet 111 and the hot air outlet 121 blow out or inhale cold air or hot air from one side or both sides of the wire 30, so that the cold air and hot air can cover the entire surface of the wire 30, thereby achieving comprehensive cooling or heating of the wire 30 and ensuring uniform overall temperature distribution; in addition, since the cold air outlet 111 and the hot air outlet 121 are located on the side of the wire 30, they will not directly blow on the surface of the wire 30, which can reduce the interference of the wind flow on the surface of the wire 30, and help improve the surface quality of the wire 30.

[0056] like Figure 5 As shown, in some embodiments, the cold air outlet 111 and / or the hot air outlet 121 are located on the side of the wire 30 away from the roller 22, and the cold air outlet 111 and the hot air outlet 121 blow out or inhale cold air or hot air from the side of the wire 30 away from the roller 22 toward the roller 22.

[0057] During the conveying process of the wire 30, one side of the wire 30 contacts the roller 22, and the other side of the wire 30 faces the heat preservation cover 10. The cold air outlet 111 and / or the hot air outlet 121 are located on the side of the wire 30 away from the roller 22 and face the surface of the wire 30. When it is necessary to blow cold air to the wire 30, the cold air flows from the cold air storage chamber 11 through the cold air outlet 111, and is blown from the side of the wire 30 away from the roller 22 toward the roller 22 to the surface of the wire 30, so as to cool the wire 30; when it is necessary to inhale cold air from the wire 30, the cold air flows from the surface of the wire 30 through the cold air outlet 111 and enters the cold air storage chamber 11. When it is necessary to blow hot air onto the wire 30, the hot air flows from the hot air storage chamber 12 through the hot air outlet 121, and is blown from the side of the wire 30 away from the roller 22 toward the roller 22 to the surface of the wire 30, thereby heating the wire 30; when it is necessary to inhale hot air from the wire 30, the hot air flows from the surface of the wire 30 through the hot air outlet 121 into the hot air storage chamber 12.

[0058] By adopting the above technical solution, cold air or hot air can be blown directly from the cold air outlet 111 or the hot air outlet 121 to the surface of the wire 30, which can achieve rapid adjustment of the temperature of the wire 30, and can more effectively promote the heat dissipation or heating of the wire 30, which helps to speed up the cooling speed or heating speed of the wire 30, so that the temperature of the wire 30 quickly reaches the required temperature, which helps to improve the quality of the wire 30.

[0059] like Figure 5As shown, in some embodiments, the thermal insulation cover 10 also includes an air duct 13, which is arranged in the hot air storage chamber 12, and one end of the air duct 13 is connected to the cold air storage chamber 11, and the other end of the air duct 13 is located on the side of the wire 30 away from the roller 22, the cold air outlet 111 is located at the connection between the air duct 13 and the cold air storage chamber 11, and the hot air outlet 121 is located at the connection between the air duct 13 and the hot air storage chamber 12, and valves 14 for controlling the inflow or outflow of cold air or hot air are provided at the cold air outlet 111 and the hot air outlet 121.

A hot air outlet 121 is provided at the connection position between the hot air storage chamber 12 and the air duct 13, and a valve 14 for controlling the inflow or outflow of hot air is provided at the hot air outlet 121.

[0062] When it is necessary to blow cold air to the wire 30, the valve 14 at the hot air outlet 121 is closed, and the valve 14 at the cold air outlet 111 is opened. The cold air flows from the cold air storage chamber 11 through the cold air outlet 111 under the action of the conveying pressure-powered air pump, and enters the opening of the high-line air-cooled roller 20 along the air duct 13, and blows toward the wire 30 on the roller 22 to cool the wire 30. When it is necessary to inhale cold air at the wire 30, the valve 14 at the hot air outlet 121 is closed, and the valve 14 at the cold air outlet 111 is opened. The cold air on the surface of the wire 30 enters the air duct 13 under the action of the conveying pressure-powered air pump, and flows along the air duct 13 through the cold air outlet 111 into the cold air storage chamber 11.

[0063] When it is necessary to blow hot air to the wire 30, the valve 14 at the hot air outlet 121 is opened, and the valve 14 at the hot air outlet 121 is closed. The hot air flows from the hot air storage chamber 12 through the hot air outlet 121 under the action of the conveying pressure-powered hot air pump, and enters the opening of the high-line air-cooled roller 20 along the air duct 13, and blows toward the wire 30 on the roller 22 to heat the wire 30. When it is necessary to inhale the hot air at the wire 30, the valve 14 at the hot air outlet 121 is opened, and the valve 14 at the hot air outlet 121 is closed. The hot air on the surface of the wire 30 enters the air duct 13 under the action of the conveying pressure-powered hot air pump, and flows along the air duct 13 through the hot air outlet 121 into the hot air storage chamber 12.

[0064] By adopting the above technical solution, the air duct 13 is directly connected to the cold air storage chamber 11 and the hot air storage chamber 12, and the cold air or hot air can be directly delivered to the side of the wire 30 away from the roller 22, which can reduce the loss of energy in the transmission process and improve the energy utilization efficiency; by controlling the valve 14 at the cold air outlet 111 and the hot air outlet 121, the inflow or outflow of cold air or hot air can be accurately adjusted, which can effectively control the temperature of the wire 30 to ensure that it is within the ideal processing temperature range.

[0065] like Figures 1 to 6 As shown, in some embodiments, the heat preservation cover 10 is connected to the side panel 21 , and the heat preservation cover 10 has a accommodating cavity 15 , in which a partition plate 16 is provided, and the partition plate 16 is used to separate the accommodating cavity 15 into a cold air storage chamber 11 and a hot air storage chamber 12 .

[0066] The accommodating cavity 15 is a hollow structure inside the heat-insulating cover 10 .

[0067] The partition plate 16 may be a plate-shaped or sheet-shaped structure, and the partition plate 16 is used to separate the accommodating chamber 15 into a cold air storage chamber 11 and a hot air storage chamber 12 that are independent of each other.

[0068] The cold air storage chamber 11 and the hot air storage chamber 12 are respectively located on both sides of the partition plate 16. In order to maintain the stability and consistency of the gas temperature in the cold air storage chamber 11 and the hot air storage chamber 12, the cold air storage chamber 11 is arranged above the hot air storage chamber 12. The cold air storage chamber 11 is away from the high-speed air cooling roller 20, and the hot air storage chamber 12 is close to the high-speed air cooling roller 20. For example, Figures 1 to 6 As shown, the cold air storage chamber 11 is located on the side of the partition plate 16 away from the high-line air-cooling roller conveyor 20 , and the hot air storage chamber 12 is located on the side of the partition plate 16 close to the high-line air-cooling roller conveyor 20 .

[0069] By adopting the above-mentioned technical scheme, the partition plate 16 divides the accommodating cavity 15 of the thermal insulation cover 10 into a cold air storage chamber 11 and a hot air storage chamber 12, so that the effective utilization of the space inside the thermal insulation cover 10 can be achieved, and at the same time, the cold air and the hot air can be effectively isolated, and the mutual interference between the cold air and the hot air can be reduced, ensuring that the storage chambers corresponding to the cold air and the hot air respectively maintain stable temperature and pressure, which helps to improve the stability and controllability of the wire 30 during the processing process, improve the processing efficiency of the wire 30, and ensure product quality.

[0070] like Figure 6 As shown, in some embodiments, the thermal insulation cover 10 also includes a guide member 17, the guide member 17 has a first end 171 and a second end 172 that are relatively arranged, the first end 171 is connected to the cold air storage chamber 11 or the hot air storage chamber 12, and the second end 172 is located on the side of the wire 30 away from the roller 22, and the guide member 17 is used to guide the cold air or hot air to the surface of the wire 30.

[0071] The guide member 17 may be a plate, sheet, or tubular structure. The guide member 17 is used to evenly guide the cold air or hot air to the surface of the wire 30 to evenly cool or heat the wire 30 .

[0072] The guide member 17 may be a structure sleeved on the air duct 13 , or may be a structure integrally formed with the air duct 13 , and the guide member 17 may also include the air duct 13 .

[0073] When blowing cold air or hot air toward the wire 30 , the cold air or hot air flows from the cold air storage chamber 11 or the hot air storage chamber 12 into the guide member 17 , flows through the first end 171 and the second end 172 in sequence, and finally blows toward the wire 30 from the second end 172 .

[0074] When cold air or hot air is sucked from the wire 30 , the cold air or hot air flows into the guide member 17 from the second end 172 , and flows into the cold air storage chamber 11 or the hot air storage chamber 12 from the first end 171 .

[0075] By adopting the above-mentioned technical solution, the guide member 17 can accurately and stably guide the cold air or hot air to the surface of the wire 30, which can reduce the energy loss caused by air flow and reduce energy waste, and at the same time make the temperature of the entire surface of the wire 30 uniformly lowered or increased, which helps to improve the uniformity and consistency of the processing of the wire 30; in addition, the guide member 17 can more accurately control the heating or cooling effect of the cold air or hot air on the wire 30, which helps to flexibly adjust the temperature according to actual processing requirements, thereby improving the controllability and accuracy of the processing of the wire 30.

[0076] In some embodiments, a size of the first end 171 is smaller than a size of the second end 172 .

[0077] The shape profile of the second end 172 can be a smooth straight line or a smooth curve with linear or nonlinear changes, the size of the first end 171 is smaller than the size of the second end 172, and the guide member 17 is horn-shaped as a whole. The cold air in the cold air storage chamber 11 or the hot air in the hot air storage chamber 12 can flow from the first end 171 to the second end 172, and blow uniformly to the surface of the wire 30 along the second end 172, and the cold air or hot air at the wire 30 can also flow along the second end 172 to the first end 171, and flow into the cold air storage chamber 11 or the hot air storage chamber 12 from the first end 171.

[0078] By adopting the above technical solution, the size of the first end 171 is smaller than that of the second end 172, so that the side of the guide member 17 close to the wire 30 is trumpet-shaped, which helps to distribute the cold air or hot air more evenly, so that the cold air or hot air forms a more uniform heating or cooling effect on the surface of the wire 30, which helps to improve the quality and consistency of the processed products; the airflow can be gradually accelerated in the process from the second end 172 to the first end 171, which can increase the speed of the airflow, and help to improve the transmission efficiency of the cold air or hot air.

[0079] In some embodiments, there are multiple cold air outlets 111 and / or hot air outlets 121 , and the multiple cold air outlets 111 and / or hot air outlets 121 are arranged at intervals on the partition plate 16 .

[0080] The high-wire air-cooled roller is usually long. In order to ensure that the wire 30 on the roller is in an environment with a uniform and stable temperature change, a plurality of cold air outlets 111 and / or hot air outlets 121 may be arranged at intervals on the partition plate 16 .

[0081] When blowing out or inhaling cold air or hot air, the plurality of cold air outlets 111 and / or hot air outlets 121 can blow cold air or hot air to the surface of the wire 30 simultaneously and evenly, so that the temperature of the entire surface of the wire 30 changes evenly.

[0082] By adopting the above technical solution, multiple cold air outlets 111 and / or hot air outlets 121 are spaced apart on the partition plate 16, so that the cold air or hot air can be evenly distributed over the entire width of the wire 30, which helps to achieve uniform heating or cooling of the surface of the wire 30 and improve the quality and consistency of the processing of the wire 30; multiple cold air outlets 111 and / or hot air outlets 121 can make it possible to heat or cool different parts of the wire 30 at the same time during the processing, which can shorten the processing time and improve production efficiency.

[0083] The present application also provides a steel cooling device, including a high-speed air-cooled roller 20 and a blower arranged below the high-speed air-cooled roller 20, and also includes a heat preservation cover 10 in any of the above items, and the heat preservation cover 10 is covered on the high-speed air-cooled roller 20.

[0084] The blower is installed below the high-speed wire air-cooling roller 20, blowing air from bottom to top to cool the wire 30. The heat preservation cover 10 is connected to the side plate 21 and covers the high-speed wire air-cooling roller 20. The surface temperature of the wire 30 is adjusted through the cold air storage chamber 11 and the hot air storage chamber 12 inside it, so that the temperature of the wire 30 meets the predetermined requirements, controls the wire 30 to undergo a beneficial phase change at the predetermined temperature, and improves the quality of the wire 30.

[0085] Optionally, the thermal insulation cover 10 can be connected to the side plate 21 through a hydraulic structure or a pneumatic structure. When the thermal insulation cover 10 is not needed, the thermal insulation cover 10 can be moved away from above the high-line air-cooled roller 20 through the hydraulic structure or the pneumatic structure. When the thermal insulation cover is needed, the thermal insulation cover 10 can be covered on the high-line air-cooled roller 20 through the hydraulic structure or the pneumatic structure.

[0086] In the steel cooling equipment provided in the embodiment of the present application, the hair dryer below the high-line air-cooling roller 20 cools the wire 30 from bottom to top, and blows out or inhales cold air and hot air to the high-line air-cooling roller 20 through the cold air storage chamber 11 and the hot air storage chamber 12 in the heat preservation cover 10, respectively, so as to adjust the temperature of the wire 30 on the high-line air-cooling roller 20, so as to make the air-cooling process of the wire 30 more uniform, improve the uniformity of cooling of the wire 30, reduce the quality problems caused by uneven metal structure, and thus improve the quality and production efficiency of the wire 30.

[0087] In some embodiments, the steel material cooling equipment further includes a plurality of groups of circulating fans, and the plurality of groups of circulating fans are arranged at intervals on both sides of the high-line air-cooling roller conveyor 20 .

[0088] The circulating fan is used to circulate the air on the surface of the wire 30 so that the temperature on the surface of the wire 30 is more uniform.

[0089] By adopting the above technical solution, the temperature on the surface of the wire 30 can be made more uniform, which helps to improve the quality and production efficiency of the wire 30.

[0090] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
