Casting is one of the common process flows in steel smelting. The temperature of the molten iron directly affects the quality of the finished steel products and the cost of production. Infrared thermal imaging can monitor the temperature of the molten iron in real time and accurately, which is of great significance for improving production efficiency, optimizing production processes and saving energy.
Pain points of traditional temperature measurement methods
Compared with infrared thermal imaging, traditional contact temperature measurement methods such as thermocouples and thermal resistors have many disadvantages:
1. During the measurement process, the characteristics and heat transfer methods of the measured object will affect the measurement results. Since the heat transfer process takes time, the temperature sensing element needs to wait for thermal equilibrium with the measured target to accurately measure the temperature, which may lead to insufficient dynamic response capabilities.
2. The contact temperature measuring element directly inserted into the measured target will affect the temperature field of the target, resulting in inaccurate measurement.
3. Temperature sensing elements are easily affected by the measurement environment, especially in high temperature or corrosive media, which will shorten the service life of the temperature sensing element, reduce the measurement accuracy, and may even make it impossible to measure.

ONick Photoelectric Infrared Thermal Imaging
Application in Temperature Monitoring of Casting Molten Iron
Install the ONick infrared thermal imager on the casting platform, aim at the molten iron between the pouring port of the casting machine and the sandbox, and monitor the molten iron temperature in real time. The data will be transmitted back to the monitoring room through a dedicated monitoring computer, and the operator can remotely view the real-time temperature of the cast iron through the display. Once an abnormal temperature is detected, an alarm will be issued immediately so that the staff can adjust the pouring temperature in time to minimize the phenomenon of unqualified castings.
