Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology for hot-rolled slabs or strips, and specifically to a temperature distribution measuring device. Background Technology

[0002] In the production of hot-rolled strip, the slab must undergo multiple rolling and cooling processes to become a steel coil or strip with the required shape and performance. The uniformity of heating and cooling of the strip affects the temperature distribution along the width of the slab and strip. Therefore, it is necessary to measure the temperature distribution along the width of the slab during hot rolling and after cooling. By measuring the temperature gradient and uniformity, adjustments can be made during the rolling process to ensure the stability of the strip rolling process, the quality of the finished strip shape, and the uniformity of product performance.

[0003] In related technologies, the infrared temperature measuring devices currently used for measuring the temperature of hot-rolled slabs or strips all suffer from a lack of measurement points and a large measurement blind zone, which cannot meet the measurement requirements for the temperature distribution in the width direction of hot-rolled slabs or strips. Furthermore, the strip may bend or deviate on the rolling mill roller table, and the lack of measurement points will also lead to deviations in measurement accuracy due to the bending or deviation of the strip.

[0004] Therefore, there is an urgent need for a temperature distribution measuring device that can measure the temperature in the width direction of hot-rolled slabs or strips and avoid deviations in measurement accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a temperature distribution measuring device to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A temperature distribution measuring device, arranged across a rolling mill roller table, includes:

[0008] A gantry crane, wherein a cooling water tank is provided on one side of the top of the gantry crane and along the length of the top of the gantry crane;

[0009] A plurality of perforations are provided along the length of the cooling water tank and perpendicular to the rolling mill roller table, and a plurality of infrared thermometers are detachably and sealed within the plurality of perforations.

[0010] The temperature distribution measuring device according to this scheme has at least the following technical advantages:

[0011] This temperature distribution measuring device features several perforations along the length of the cooling water tank and perpendicular to the rolling mill rollers. Each perforation contains a removable, sealed infrared thermometer, with the thermometer probes pointing vertically downwards. This allows for multi-point temperature measurement along the width of the hot-rolled slab or strip, providing more comprehensive and detailed temperature information compared to traditional methods with fewer measurement points. It more accurately reflects the temperature distribution across the entire width, avoiding the impact of strip bending or deviation on measurement accuracy. This effectively meets the requirements for measuring the temperature distribution across the width of the hot-rolled slab or strip, improves the ability to identify the edges of the hot-rolled slab or strip, and ensures the stability of the hot rolling process, the quality of the strip shape, and the uniformity of strip performance. Furthermore, the cooling water tank provides cooling for the infrared thermometers through water circulation, preventing damage from excessive heat and ensuring the lifespan and performance of the infrared thermometers.

[0012] As a further embodiment of this utility model: a water inlet is provided at the bottom of one end of the cooling water tank, and a water outlet is provided at the top of the other end of the cooling water tank.

[0013] Because the cooling water tank has an inlet at the bottom of one end and an outlet at the top of the other end, it adopts a bottom-in, top-out configuration. When the infrared thermometer needs cooling, more cooling water can accumulate in the tank, allowing the infrared thermometer to be submerged and fully exchange heat. This quickly removes the heat from the infrared thermometer, facilitating continuous temperature measurement of hot-rolled slabs or strips. It also prevents damage to the infrared thermometer due to excessive temperature and improves the continuity of temperature measurement.

[0014] As a further embodiment of this utility model, the spacing between several adjacent perforations is 25mm-50mm.

[0015] Because the spacing between several adjacent perforations is 25mm-50mm, the infrared thermometer can accurately capture the subtle temperature changes in the width direction of the hot-rolled slab or strip, providing sufficient data points for accurately plotting the temperature distribution curve, thereby improving the accuracy and resolution of temperature measurement, more clearly reflecting the temperature gradient and non-uniformity, and ensuring the accuracy of temperature measurement of the hot-rolled slab or strip.

[0016] As a further embodiment of this utility model: the perforations are arranged in two rows along the length of the cooling water tank, and the perforations in the two rows are staggered.

[0017] Because several perforations are arranged in two rows along the length of the cooling water tank, and the perforations in the two rows are staggered, the infrared thermometers can be more densely distributed in the width direction of the hot-rolled slab or strip, ensuring more comprehensive coverage of measurement points, reducing measurement blind spots, and capturing minute temperature changes in the width direction more precisely. This further meets the temperature measurement requirements of the temperature distribution in the width direction of the hot-rolled slab or strip, improves the identification ability of the edges of the hot-rolled slab or strip, and thus improves the stability of the hot rolling process, the strip shape quality, and the uniformity of strip performance.

[0018] As a further embodiment of this utility model: a plurality of connecting blocks are provided on one side of the cooling water tank, and the cooling water tank is connected to the gantry frame through the plurality of connecting blocks.

[0019] By installing several connecting blocks on one side of the cooling water tank, the cooling water tank is connected to the gantry frame through these connecting blocks, making the cooling water tank and the gantry frame an integrated unit. This can effectively improve the stability and reliability of the cooling water tank, prevent the infrared thermometer from vibrating or shaking due to external forces, and ensure the stability and accuracy of temperature measurement.

[0020] As a further improvement of this utility model, the infrared thermometer is an industrial online infrared thermometer.

[0021] As a further improvement of this utility model, the temperature measurement range of the infrared thermometer is 300℃-1400℃.

[0022] Because this infrared thermometer is an industrial online infrared thermometer, it uses a non-contact measurement method, eliminating the need for direct contact with hot-rolled slabs or strips. This avoids damage to the infrared thermometer caused by contact with high-temperature objects and does not interfere with the temperature field of the object being measured. It can accurately measure the surface temperature of the object, ensuring the accuracy and reliability of temperature measurement for hot-rolled slabs or strips. Furthermore, this temperature measurement range completely covers the entire temperature range of hot rolling production, ensuring accurate temperature measurement of slabs or strips at every stage of production, thus improving the applicability and versatility of temperature measurement.

[0023] As a further improvement of this utility model, the cooling water tank is made of stainless steel.

[0024] Because the cooling water tank is made of stainless steel, its corrosion resistance is greatly improved. It can effectively resist the corrosion of the tank by chemicals in the cooling water, reduce water leakage or damage caused by corrosion, ensure the service life of the tank, and thus ensure the stability and reliability of the entire device.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] like Figure 1-3 The present invention provides a temperature distribution measuring device, which is set across the rolling mill roller table 1 and includes: a gantry frame 2, a cooling water tank 3 is set on one side of the top of the gantry frame 2 and along the length of the top of the gantry frame 2; a plurality of through holes 31 are set along the length of the cooling water tank 3 and perpendicular to the rolling mill roller table 1, and a plurality of infrared thermometers 4 are detachably and sealed in the plurality of through holes 31.

[0038] Specifically, the temperature distribution measuring device has several perforations 31 arranged along the length of the cooling water tank and perpendicular to the rolling mill roller table 1. Several infrared thermometers 4 are detachably and sealed within the perforations 31, with the probes of the infrared thermometers 4 pointing vertically downwards. This allows for multi-point temperature measurement of the width direction of the hot-rolled slab or strip, enabling more comprehensive and detailed temperature information in the width direction of the slab or strip. Compared to single-point measurement, it can more accurately reflect the temperature distribution in the entire width direction, avoiding the impact of strip bending or deviation on the accuracy of temperature measurement. This effectively meets the temperature measurement requirements of the width direction of the hot-rolled slab or strip, improves the identification ability of the edges of the hot-rolled slab or strip, and ensures the stability of the hot rolling process, the strip shape quality, and the uniformity of strip performance. Furthermore, the cooling water tank 3 provides cooling for the infrared thermometers 4 through water circulation, preventing damage to the infrared thermometers 4 due to excessive temperature and ensuring the service life and performance of the infrared thermometers 4.

[0039] like Figure 1 As shown, a water inlet 32 ​​is provided at the bottom of one end of the cooling water tank 3, and a water outlet 33 is provided at the top of the other end of the cooling water tank 3.

[0040] Specifically, since the cooling water tank 3 has an inlet 32 ​​at the bottom of one end and an outlet 33 at the top of the other end, it adopts a bottom-in, top-out configuration. When the infrared thermometer 4 needs to be cooled, more cooling water can accumulate in the cooling water tank 3, allowing the infrared thermometer 4 to be immersed in the cooling water and fully exchange heat. This quickly removes the heat from the infrared thermometer 4, facilitating temperature measurement of the next batch of hot-rolled slabs or strips. It also prevents damage to the infrared thermometer 4 due to excessive temperature and improves the continuity of temperature measurement.

[0041] According to an embodiment of the present invention, the spacing between several adjacent perforations 31 is 25mm-50mm.

[0042] Specifically, since the spacing between several adjacent perforations 31 is 25mm-50mm, the infrared thermometer 4 can accurately capture the subtle temperature changes in the width direction of the hot-rolled slab or strip, providing sufficient data points for accurately plotting the temperature distribution curve, thereby improving the accuracy and resolution of temperature measurement, more clearly reflecting the temperature gradient and non-uniformity, and ensuring the accuracy of temperature measurement of the hot-rolled slab or strip.

[0043] Furthermore, such as Figure 2 As shown, several perforations 31 are arranged in two rows along the length of the cooling water tank 3, and the two rows of several perforations 31 are staggered.

[0044] Specifically, since several perforations 31 are arranged in two rows along the length of the cooling water tank 3, and the two rows of several perforations 31 are staggered, the infrared thermometers 4 can be more densely distributed in the width direction of the hot-rolled slab or strip, ensuring more comprehensive coverage of measurement points, reducing measurement blind spots, and capturing minute temperature changes in the width direction more precisely. This further meets the temperature measurement requirements of the temperature distribution in the width direction of the hot-rolled slab or strip, improves the identification ability of the edge of the hot-rolled slab or strip, and thus improves the stability of the hot rolling process, the strip shape quality, and the uniformity of strip performance.

[0045] like Figure 1 and Figure 2 As shown, a number of connecting blocks 34 are provided on one side of the cooling water tank 3, and the cooling water tank 3 is connected to the gantry frame 2 through the connecting blocks 34.

[0046] Specifically, by setting several connecting blocks 34 on one side of the cooling water tank 3, the cooling water tank 3 is connected to the gantry frame 2 through several connecting blocks 34, so that the cooling water tank 3 and the gantry frame 2 are connected as one unit, which can effectively improve the stability and reliability of the cooling water tank 3, avoid the infrared thermometer 4 from vibrating or shaking due to external forces, and ensure the stability and accuracy of temperature measurement.

[0047] According to an embodiment of this utility model, the infrared thermometer 4 is an industrial online infrared thermometer, and the temperature measurement range of the infrared thermometer 4 is 300℃-1400℃.

[0048] Specifically, since infrared thermometer 4 is an industrial online infrared thermometer, it adopts a non-contact measurement method, eliminating the need for direct contact with hot-rolled slabs or strips. This avoids damage to the infrared thermometer 4 caused by contact with high-temperature objects and does not interfere with the temperature field of the measured object. It can accurately measure the surface temperature of the object, ensuring the accuracy and reliability of temperature measurement for hot-rolled slabs or strips. Furthermore, this temperature measurement range completely covers the entire temperature range of hot-rolling production, ensuring accurate temperature measurement of slabs or strips at every stage of production, thus improving the applicability and versatility of temperature measurement.

[0049] It should also be noted that the cooling water tank 3 is made of stainless steel.

[0050] Specifically, since the cooling water tank 3 is made of stainless steel, its corrosion resistance is greatly improved. It can effectively resist the corrosion of the tank body by chemicals in the cooling water, reduce water leakage or damage caused by corrosion of the cooling water tank 3, ensure the service life of the water tank, and thus ensure the stability and reliability of the entire device.

[0051] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
