Description

Technical Field

[0001] This utility model relates to the technical field of temperature measuring device accessories, and in particular to the cooling and temperature reduction of temperature measuring guns used in steelmaking, specifically referring to an air-cooled temperature control device for steelmaking temperature measuring guns. Background Technology

[0002] Steelmaking temperature guns are mainly used to measure the temperature of molten steel during the steelmaking process, providing data for production operations. Because the molten steel is very hot, the temperature gun needs to be cooled and controlled after being removed from the molten steel to reduce the continued impact of the high temperature.

[0003] Currently, temperature control for temperature measuring guns primarily relies on natural air cooling or simple fan cooling. After being removed from molten steel, the temperature measuring gun is cooled on its surface by natural convection or a simple fan (such as an industrial electric fan). This cooling method is slow and uneven, failing to effectively suppress the rapid rise in gun body temperature. This leads to deformation and burn-out of the gun body materials (such as thermocouple probes and metal rods) due to continuous high temperatures, resulting in a short service life. Furthermore, re-measuring before the temperature has sufficiently decreased will produce significant errors (such as data drift and response delay), affecting the accuracy of molten steel temperature measurement and the stability of the steelmaking process. Manual operation requires frequent replacement of the temperature measuring gun, which is labor-intensive and increases spare parts costs.

[0004] To improve the cooling rate, auxiliary cooling methods are sometimes added, such as temporary immersion in coolant (medium water) or manual application of medium water. However, these methods are not operated in a standardized manner, the cooling effect is unstable, and they increase the complexity of the operation and the safety hazards of high-temperature liquids in steel plants. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a wind-cooled temperature control device for steelmaking temperature measuring guns. It uses air cooling to cool and control the temperature of the measuring gun, improving cooling efficiency while avoiding the safety hazards of high-temperature liquids caused by using liquid cooling media.

[0006] This utility model is achieved through the following technical solution: a steelmaking temperature measuring gun air-cooled temperature control device is provided, including a chamber, a jet pipe passing through the chamber, and two support boxes fixed to the upper surface of the top plate of the chamber. The two boxes are close to each other to form a support for the temperature measuring gun, and an air outlet duct is formed between the two support boxes below the temperature measuring gun. An air outlet strip hole communicating with the air outlet duct is opened on the top plate of the chamber. A plurality of jet holes are opened on the pipe wall of the jet pipe below the air outlet strip hole. One end of the jet pipe is sealed, and the other end is connected to the air supply mechanism.

[0007] This solution uses a support box to support the temperature measuring gun, making it easy to place. In use, compressed air is introduced into the jet pipe by the air supply mechanism. After being ejected through the jet hole, the compressed air enters the air outlet duct through the air outlet strip hole and flows through the temperature measuring gun. The high-speed flow of gas is used to cool the temperature measuring gun, achieving rapid cooling and temperature control.

[0008] As an optimization, the jet pipe is connected to the air supply mechanism via a hose, and one end of the jet pipe connected to the hose extends out of the chamber. The jet orifice is elongated, and the jet pipe has two sets of jet orifices, with the jet orifices in each set spaced apart along the length direction. Along the circumferential direction, each jet orifice in one set corresponds to the area between adjacent jet orifices in the other set. This optimized design avoids excessive weakening of the jet pipe's strength caused by making the jet orifice run through the entire length direction, and ensures uniform cooling of the temperature gun along its entire length by repeatedly rotating the jet pipe.

[0009] As an optimization, a U-shaped groove plate with an upward-facing opening is fixed inside the chamber. The jet pipe is supported and placed in the groove of the U-shaped groove plate, with the lower edge of the jet pipe contacting the bottom plate of the U-shaped groove plate. The two side plates of the U-shaped groove plate contact the jet pipe respectively, and the upper ends of the two side plates of the U-shaped groove plate are lower than the center of the jet pipe. This optimized solution, by setting the U-shaped groove plate to support the jet pipe, not only facilitates the rotation operation of the jet pipe but also prevents the jet pipe from deflecting, ensuring that the jet hole can be rotated to the position opposite to the air outlet hole.

[0010] As an optimization, the outer wall of the jet pipe is fixed with limiting plates located on the left and right sides of the two sets of jet holes along the circumferential direction. When the left limiting plate rotates with the jet pipe to the upper left side of the U-shaped groove plate, the right jet hole is located directly below the air outlet hole. Conversely, when the right limiting plate rotates with the jet pipe to the upper right side of the U-shaped groove plate, the left jet hole is located directly below the air outlet hole. This optimization scheme, by setting limiting plates on both sides, facilitates control of the rotation angle of the jet pipe and improves operational convenience.

[0011] As an optimization, strips are fixed to the lower surface of the top plate of the chamber, located on both sides of the air outlet. Rubber plates extending downwards to the jet pipes are fixed to these strips, and the distance between the two rubber plates is greater than the width of the jet outlet. This optimization scheme, by setting the strips, facilitates the fixing of the rubber plates and, by creating an obstruction to the airflow, allows the gas to pass through the air outlet better.

[0012] As an optimization, the upper end of the support box is fixed with spaced protrusions, and the temperature measuring gun is supported on the protrusions, forming an air vent gap between the temperature measuring gun and the support box. This optimization scheme, by setting the protrusions, creates an air vent gap between the temperature measuring gun and the support box, which facilitates gas flow and further improves the cooling effect.

[0013] As an optimization, the ends of the two support boxes that are close together are lower than the other end, and the top surfaces of the two support boxes form a V-shape. This optimized design facilitates the placement of the temperature measuring gun after it has been removed from the molten steel. Simply place it on the inclined surface of the V-shape, and the temperature measuring gun can slide along the inclined surface to the top of the air outlet, reducing the difficulty of placing the high-temperature temperature measuring gun.

[0014] The beneficial effects of this utility model are as follows: the two supporting boxes are used to support the temperature measuring gun, which ensures the stability of the temperature measuring gun. At the same time, the space between the two supporting boxes forms an air outlet, which facilitates the flow and guidance of the gas ejected from the jet pipe, thereby improving the cooling efficiency.

[0016] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0017] like Figure 1 The illustrated steelmaking temperature measuring gun air-cooled temperature control device includes a chamber 1, an air jet pipe 5 extending into the chamber, and two support boxes 3 fixed to the upper surface of the top plate 12 of the chamber. The ends of the two support boxes 3 that are close together support the temperature measuring gun 4. An air outlet duct 6 is formed between the two support boxes, located below the temperature measuring gun, and the length of the air outlet duct is not less than the length of the temperature measuring gun. When the two support boxes support the temperature measuring gun, the temperature measuring gun is in a horizontal position.

[0018] The chamber includes a frame and a top plate 12 welded to the top of the frame. Protective side plates are welded to the sides and bottom of the frame. The support box has a hollow internal structure to reduce equipment weight and manufacturing costs. The upper end of the support box is fixed with spaced protrusions 16, on which the temperature measuring gun is supported. A vent gap is formed between the temperature measuring gun and the support box to improve gas flow. The protrusions can be formed by weld points during the welding process of the support box.

[0019] To prevent the temperature gun from rolling off, in this embodiment, the two support boxes are positioned so that one end is lower than the other, and the top surfaces of the two support boxes form a V-shape. After the temperature gun is removed from the molten steel, it is in a high-temperature state. At this time, the temperature gun is placed on the top surface of the V-shape of the support box, and it slides down to the support point with the help of the inclined plane, which greatly reduces the difficulty of placing the temperature gun.

[0020] The top plate 12 of the chamber is provided with an air outlet hole 11 that communicates with the air outlet duct. The air outlet hole is located directly below the air outlet duct, and the length of the air outlet hole is not less than the length of the temperature measuring gun, so as to achieve cooling and temperature control of the entire temperature measuring gun.

[0021] During cooling operations, both the temperature gun and the air jet pipe are horizontal. The air jet pipe has several air jet holes 9 located below the air outlet holes. One end of the air jet pipe 5 is sealed, and the other end is connected to the air supply mechanism. The air supply mechanism uses existing technology, such as an air compressor, high-pressure pump, or compressed air tank, and will not be described in detail here.

[0022] The jet pipe is connected to the air supply mechanism via a hose 8, and one end of the jet pipe connected to the hose extends out of the chamber. An operating handle 7 located outside the chamber is installed on the jet pipe, which can be easily rotated by turning the handle.

[0023] The jet nozzle 9 is elongated, and the jet pipe has two sets of jet nozzles arranged alternately. That is, the jet nozzles in each set are spaced apart along the length direction, and along the circumferential direction, each jet nozzle in one set corresponds to the area between adjacent jet nozzles in the other set. By setting two sets of alternately arranged jet nozzles, the problem of weakened jet pipe strength and easy deformation caused by a continuous jet nozzle is avoided. In use, by continuously rotating the jet pipe, the two sets of jet nozzles alternately blow air towards the air outlet 11, ensuring uniform cooling of the temperature measuring gun.

[0024] To facilitate the installation of the jet pipe, a U-shaped groove plate 14 with its opening facing upwards is fixed inside the chamber. In this embodiment, a crossbeam 2 supporting the U-shaped groove is welded onto the frame of the chamber. The jet pipe is supported and placed in the groove of the U-shaped groove plate, with the lower edge of the jet pipe contacting the bottom plate of the U-shaped groove plate. The two side plates of the U-shaped groove plate are in contact with the jet pipe, and the upper ends of the two side plates of the U-shaped groove plate are lower than the center of the jet pipe.

[0025] To facilitate manual control of the rotation angle of the jet pipe, this embodiment has a limiting plate 10 fixed on the outer wall of the jet pipe, located on the left and right sides of the two sets of jet holes along the circumferential direction. When the limiting plate on the left side rotates with the jet pipe to the upper left side of the U-shaped groove plate, the jet hole on the right side is located directly below the air outlet hole. When the limiting plate on the right side rotates with the jet pipe to the upper right side of the U-shaped groove plate, the jet hole on the left side is located directly below the air outlet hole.

[0026] The lower surface of the top plate of the chamber is fixedly connected to strips 13 located on both sides of the air outlet. Rubber plates 15 extending downward to the jet pipe are fixedly connected to the strips, and the distance between the two rubber plates is greater than the width of the jet outlet. By setting the rubber plates, the airflow to both sides is reduced, so that more gas ejected from the jet outlet of the jet pipe enters the air outlet duct through the air outlet 11, thereby improving the efficiency of cooling and temperature control.

[0027] To simultaneously cool and control the temperature of two temperature guns, two sets of support boxes can be installed on the chamber body, with air jet pipes, air outlet holes, and U-shaped groove plates respectively installed below the two sets of support boxes.

[0028] In this embodiment, the high-temperature measuring gun taken from the molten steel is placed on the support box. Compressed air is supplied to the air jet pipe through the air supply mechanism. The compressed air flows through the air jet hole of the air jet pipe, through the air outlet hole, and blown to the measuring gun through the air outlet duct. The flowing air carries away the heat of the measuring gun, realizing cooling and temperature control. The operator can improve the uniformity of cooling of the measuring gun by repeatedly rotating the air jet pipe. During the rotation of the air jet pipe, the limiting plate is used to limit the rotation angle of the air jet pipe so that the air jet hole is better aligned with the air outlet hole.

[0029] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
