Description

Technical Field

[0001] This utility model relates to the technical field of steel rolling cooling equipment, specifically a steel rolling infrared temperature measurement combined with a steam extraction and cooling device. Background Technology

[0002] In the steel rolling process, accurate monitoring of the steel surface temperature plays a crucial role in ensuring steel quality, controlling rolling process parameters, and improving production efficiency. Currently, most steel rolling processes use contact thermocouples or single-wavelength infrared thermometers for cooling, which have low temperature measurement accuracy and are easily affected by water mist and iron oxide scale. Steam will condense on the lens surface of the infrared thermometer, forming water droplets or mist, which will block the optical window of the thermometer, causing the infrared radiation signal to fail to reach the detector accurately, resulting in measurement deviations or even failure to measure. Steam that permeates the air will corrode the equipment over time and affect the surrounding production environment. Utility Model Content

Several cooling nozzles are installed on the outlet of the pair of control valves. The mounting bracket is installed in the middle of the front wall of the fixed plate.

One end of a pair of steam delivery pipes is installed on top of the suction fans. The collection box is installed above the water storage tank. The other end of the pair of steam delivery pipes is connected to the collection box. The steam condensation recovery assembly is installed on the collection box.

[0012] Beneficial effects

[0013] This utility model provides a steam extraction and cooling device for steel rolling combined with infrared temperature measurement, which has the following beneficial effects: This solution uses an infrared monitoring and cooling steam extraction structure. By setting up a pair of extraction fans and a pair of steam delivery pipes, it can quickly and effectively extract the steam generated on the surface of the steel rolling from the temperature measurement area, reducing the interference of steam on the dual-wavelength infrared thermometer and ensuring that the thermometer can accurately receive the infrared radiation signal emitted by the surface of the steel rolling. This greatly improves the accuracy and reliability of steel rolling temperature monitoring, providing a strong guarantee for the precise control of the rolling process. The setting of a water storage tank, control valve, and several cooling nozzles allows for precise control of the water spray volume and spray range according to actual production needs, enabling targeted cooling treatment of the steel rolling surface. The combined use of a collection tank and a steam condensation and recovery component allows for the condensation and recovery of the extracted steam. The condensed water can flow back to the water storage tank through the drain hole, realizing the utilization of water resources. Recycling reduces water waste and lowers production costs, while also avoiding the environmental impact of direct steam emissions, meeting the requirements of green production. Furthermore, the use of a dual-wavelength infrared thermometer for steel rolling temperature monitoring, compared to a single-wavelength infrared thermometer, calculates temperature by measuring the radiation ratio of two different wavelengths. This effectively counteracts the influence of environmental interference such as smoke, water vapor, and dust on the measurement results, maintaining measurement accuracy. It also solves the problems of existing steel rolling processes that mostly use contact thermocouples or single-wavelength infrared thermometers for cooling, resulting in low temperature measurement accuracy, susceptibility to water mist and iron oxide scale interference, condensation of steam on the infrared thermometer lens surface forming water droplets or mist that obstructs the optical window, preventing the infrared radiation signal from accurately reaching the detector, leading to measurement deviations or even failure to measure. Additionally, steam permeating the air over time can corrode equipment and impact the surrounding production environment. Attached Figure Description

A water storage tank 3 is embedded in the middle of the fixed plate 2 to store cooling water. A pair of control valves 4 are installed on the lower wall of the water storage tank 3, allowing precise control of the cooling water flow. Several cooling nozzles 5 are installed at the outlets of the control valves 4. When the control valves 4 are opened, cooling water is sprayed from the cooling nozzles 5 to cool the rolled steel. A mounting bracket 6 is installed in the middle of the front wall of the fixed plate 2, and a dual-wavelength infrared thermometer 7 is installed on the lower wall of the mounting bracket 6.

A pair of suction fans 8 are installed in the middle of the two pairs of fixed support rods 1 via connecting rods 12. During the rolling process, a large amount of steam is generated. After the suction fans 8 are started, they can draw in the surrounding steam. One end of a pair of steam delivery pipes 9 is installed at the top of the suction fans 8, and the other end is connected to the collection box 10. The steam drawn by the suction fans 8 is delivered to the collection box 10 through the steam delivery pipes 9.

[0024] In the specific implementation process, furthermore, mounting plates 11 are provided at the bottom of the two pairs of fixed support rods 1.
