As an important aluminum product, hot-rolled aluminum is used in aerospace, electronics, transportation, architectural decoration, etc. Hot-rolling quality control is the focus of hot-rolled aluminum profile production, and rolling temperature is an important parameter in the hot-rolling process of aluminum strips. It not only affects the deformation resistance, plasticity and deformation performance parameters of aluminum profiles, but also passes aluminum The microstructure of the profile affects the microstructure and properties of the rolled product. Accurate temperature measurement helps to control the operation of the aluminum strip mill and detect problems before they fail. Also, the quality of finished aluminum products can be verified by thermal monitoring at critical points. Gewu Youxin infrared thermal imaging camera can efficiently and accurately control the temperature during the aluminum hot rolling production process through non-contact precise temperature measurement, which improves the production efficiency and product quality of aluminum hot rolling.

In traditional hot rolling, hand-held thermocouples are used to measure the temperature of ingots, intermediate slabs and hot-rolled coils, and the coil temperature is measured after the fact, which has no effect on control; with the development of non-contact infrared thermal imaging technology The development and application of online thermal imaging high-precision temperature real-time detection system has changed from the previous post-inspection to real-time temperature monitoring and feedback control, so that the temperature in the entire length direction of the hot-rolled coil is in a controlled state, realizing the hot-rolled coil The temperature is controlled online, and its control accuracy is less than 8°C, which provides a guarantee for obtaining stable strip performance.

The places where temperature measurement is needed on the hot rolling mill production line mainly include temperature measurement in front of the furnace, temperature measurement before thick shear, temperature measurement before thin shear, temperature measurement at the outlet of continuous rolling mill and coil temperature measurement. Traditional temperature measurement methods generally need to be measured at each measurement The temperature points are distributed and controlled by multiple temperature measuring thermocouples, and the loss rate of the thermocouples is high, so it is impossible to measure the temperature continuously. The infrared camera can make up for the inconvenience and defects of the thermocouple. Gewu Youxin infrared thermal imaging camera has the following advantages for temperature monitoring of hot rolling mills:

1: Infrared thermal imaging temperature measurement is a non-contact temperature measurement method, which will not affect the normal operation of aluminum hot rolling production;

2: The thermal imaging camera can monitor the temperature in the production process 24 hours a day in real time, and generate thermal imaging pictures, which can grasp the temperature situation in time;

3: The infrared thermal imaging camera has a wide range of temperature measurement, which can be measured from extremely low temperature to high temperature, and can meet the needs of different rolling mill production stages;

4: The infrared thermal imaging camera has an alarm temperature, and can also set different alarm thresholds, and set different alarm temperatures for different equipment and production environments. When the normal temperature is detected, it will immediately alarm to prevent hidden dangers;

5: The thermal imaging camera can record and analyze temperature data, which helps to track temperature changes and trends in the production process, and further optimize the process. The high-resolution and multi-point temperature measurement functions of the thermal imaging camera make it suitable for different The monitoring requirements in the rolling mill stage are helpful to optimize the process and prevent defects, and play an important role in temperature measurement, improvement of production efficiency, quality control and safety in aluminum hot rolling production.
