Problems solved by technology

[0003] The X-ray source and signal detector in the measurement device are very sensitive to temperature changes, and the temperature change will directly affect the characteristics of the electronic components in the X-ray source and signal detector, which will cause drift, increase noise, and ultimately affect the measurement precision
In addition, too high temperature will also affect the service life of the X-ray source and signal detector. Therefore, when designing the thickness / convexity online measuring device, it must be considered to be equipped with an effective cooling system to keep its temperature constant.
In the hot rolling production process, the temperature of the rolled metal sheet and strip is very high, and when the sheet and strip pass through the thickness / convexity online measuring device, a large amount of heat radiation is generated; in addition, the X-ray source also generates a large amount of heat when it is working , which will cause the temperature of the X-ray source and signal detector to rise, thus affecting the measurement accuracy

Embodiment Construction

[0021] figure 1 As shown, the system configuration of the thickness / convexity measuring device mainly includes: X-ray source part, detector part, electrical control part, mechanical part, convexity detection signal processing unit, and man-machine interface part.

[0022] Radiometry works by using the attenuation (or absorption of radiation by the material) properties of radiation within the metal to measure the thickness of the strip. The X-ray or isotope radiation emitted by the radiation source penetrates the measured strip, and the radiation energy is partially absorbed, and the detector located on the other side of the strip measures the radiation intensity. The detector converts the detected radiation intensity signal into a current signal proportional to the thickness of the strip and outputs it to the signal processing computer, and the signal processing computer calculates the thickness of the strip to be measured.

Abstract

A cooling system for the thickness-convexity measuring apparatus is composed of a cooling subsystem for the casing of X-ray source and featuring that its cooling pipeline is embedded in the cavities on the external surface of casing, a cooling subsystem for the inner side wall of C-shaped frame and consisting of upper, middle and lower water cooling jackets, and an air cooling subsystem for cooling the internal space of said C-shaped frame by dried compressed air.

Description

technical field [0001] The invention relates to a cooling system, in particular to a cooling system of an on-line measuring device for strip thickness / convexity during the hot rolling of metal strips, and belongs to the technical field of metal rolling processing. Background technique [0002] The strip thickness / convexity online measuring device is widely used in the hot rolling production of metal strips. The system provides high-precision measurement values, and the accuracy of measurement results directly affects the effect and accuracy of control, such as figure 1 Shown is a schematic diagram of the system configuration of the thickness / convexity measuring device. [0003] The X-ray source and signal detector in the measurement device are very sensitive to temperature changes, and the temperature change will directly affect the characteristics of the electronic components in the X-ray source and signal detector, which will cause drift, increase noise, and ultimately af...
