Guidance on the operating principle of the two-color fixed thermometer:
The steel industry uses thermometers because the products are in motion and the temperature is very high. The ordinary application in the steel industry is that the temperature is a continuous state, and the melted steel begins to transform into blocks. The key to preventing deformation of steel is to reheat it at the same temperature, and infrared thermometers are used to measure the internal temperature of the reheater. In high-temperature rotary mills, infrared thermometers are used to confirm that the temperature of the product is within the rotation limit. In the cooling rolling mill, infrared thermometers are used to monitor the temperature of steel during the cooling process.
