Water cooling device of steelmaking furnace infrared imaging temperature measurement system

Abstract

The invention discloses a water cooling device of a steelmaking furnace infrared imaging temperature measurement system. An infrared temperature measurement device is mounted in a cooling device body, the cooling device body comprises a cooling pipe, and a plurality of through holes formed in the direction of the cooling pipe are arranged in a pipe body of the cooling pipe. Two runner pipes are mounted in each through hole. A liquid inlet and a liquid outlet are formed in the surface of the cooling device body. A plurality of connecting pipes are further included. The liquid inlet and the liquid outlet communicate through the connecting pipes and the runner pipes, and a runner is formed in the cooling pipe. The problem that in the prior art, the structure is complex due to the fact that a spiral pipe water passing mode is adopted for cooling is solved, the through holes are formed in the pipe body of the cooling pipe, the runner pipes are arranged in the through holes and are matched with the connecting pipes for communication, and the structural machining difficulty is greatly reduced.

Description

technical field [0001] The invention relates to a water cooling device, in particular to a water cooling device for an infrared imaging temperature measurement system of a steelmaking furnace. Background technique [0002] At present, in the steelmaking industry, the temperature detection method is often used to measure the temperature of molten steel by intermittently injecting thermocouples. Each temperature measurement needs to consume a thermocouple. The cost of temperature measurement is high and continuous measurement is not possible. The infrared imaging temperature measurement system can accurately detect the temperature of molten steel in the furnace in real time, but the infrared imaging thermometer needs to directly observe the high temperature molten steel in the furnace, so it must be installed close to the furnace wall, so that the ambient temperature of the infrared imaging temperature measurement system can be as high as Celsius 200-300 degrees. The internal...

Problems solved by technology

[0003] To achieve high heat dissipation efficiency in the traditional water-cooled structure, the method of passing water through the spiral tube is generally used. However, because the contact area between the spiral tube itself and the infrared temperature measuring tube is too small, it is necessary to fill the liquid heat conduction between the spiral tube and the infrared temperature measuring tube. Medium to increase the speed of heat transfer, such a structure brings strict sealing requirements, making the structure complex and greatly increasing the difficulty of processing
