Background

In the continuous casting process, the production processes such as the speed control of the continuous casting machine's billet drawing roller and the fixed-length cutting control are very sensitive to the temperature of the billet. If the temperature is too high during the billet pulling process, the billet will not be fully solidified, and the final solidification time will be much lower than the straightening roller and the local chain breakage rectification period, which may cause the production quality to decline and the billet to break; if the temperature is too low during the billet pulling process, the billet will solidify prematurely, making it difficult to plasticize and damaging the life of the production machinery. Therefore, the temperature of the billet is an important parameter that cannot be ignored in the continuous casting process.

Infrared thermal imaging thermometer is a device that converts the target temperature distribution into a visible image and an accurate temperature value by detecting the infrared radiation of the target and performing signal processing, photoelectric conversion and other means. The infrared thermal imaging thermometer accurately quantifies the actual detected heat and images the entire target in real time in the form of a surface, so it can accurately identify the real-time temperature of multi-track billets. The operator obtains the real-time temperature of the billet through the image color and hot spot tracking display function displayed on the screen, and strictly analyzes it, thereby reflecting high efficiency and high accuracy in confirming the problem.

The infrared thermal imaging thermometer uses advanced non-contact infrared detection technology to quickly, accurately, conveniently and intuitively display the distribution of the surface temperature field of the measured object and measure the surface temperature of the object. It can quickly test the surface temperature reading of the object without direct contact with the surface of the measured object, and can reliably measure the surface temperature of hot, dangerous or difficult-to-reach objects. The infrared thermal imager has a very fast measurement speed and can intuitively and continuously test the temperature changes on the surface of the object.
