YTLZ-FR type continuous casting optical fiber infrared temperature measurement systemIntroduction:
When the equipment and process conditions are constant, the pulling speed and cooling water volume are important factors that directly affect the surface temperature of the casting billet, and their combined effect determines the change in casting billet temperature. In terms of heat transfer in castings, we hope to increase the cooling intensity and accelerate the solidification rate in order to improve the production capacity of the casting machine; However, from the perspective of metallurgical quality, inappropriate secondary cooling intensity can cause various quality defects. Therefore, it is necessary to balance both production and metallurgical quality, and choose and strictly control the secondary cooling intensity reasonably. The cooling control of continuous casting billets is a dynamic control method that adjusts the cooling intensity in a timely manner based on changes in process conditions during the casting process.
YTLZ-FR type continuous casting optical fiber infrared temperature measurement systemFunction:
1. Detect the surface temperature of the casting billet, cooling water flow rate, pressure, pulling speed, steel temperature, and temperature difference in the crystallizer, as well as manually input information, and perform corresponding calculations and processing according to the requirements of the control system and model.
2. The system performs fuzzy processing based on the parameters provided by the detection and information processing sections, forming a database and rule library. The fuzzy inference is performed by the inference machine, and the output parameters are used to control the cooling water volume of each section.
3. The change in water volume output by fuzzy control corresponds to the change in casting temperature, and the rapid increase in water volume corresponds to a sharp rise in temperature; The decrease in water volume corresponds to a decrease in temperature, which conforms to the cooling law of temperature changes in castings.
4. The principle of the YTLZ-FR system is to track the surface temperature of the casting billet (measured value) and compare it with the ideal casting billet surface temperature set (calculated by the model). If there is a deviation, it is corrected by automatically adjusting the secondary cooling intensity, thereby achieving the optimization of the casting billet surface temperature and casting billet quality.
