The Application of Breakout Prediction System with Thermal Imaging

The system of breakout prediction with thermal imaging is developed, which used cubic spline interpolation algorithm, based on the characteristics of the practical temperature data. This system is designed using VC++. In the measuring temperature experiment, more thermocouples are arranged in the copper plate of the mold. Three rows of thermocouples are installed in the mold copper plate, and there are two adjacent thermocouples in one location. In the system, the temperature field of the mold copper plate is shown as an image, and the function of monitoring temperature on-line is realized. The image is more exquisite and pliable because of existing more measuring temperature points. This system with thermal imaging has a great application value in the steel factories.

Investigation of Temperature and Deformation of Mold Copper Plate in Slab Continuous Casting

Based on the cooling parameters of the mold copper plate for slab continuous casting in a steelmaking plant, the three-dimensional calculating model of the copper plate was established, and three-dimensional distributions of temperature, thermal stress and strain were simulated numerically by using finite element method (FEM). The maximum deformation of the mold copper plate, the highest temperature and thermal stress were obtained. This research is useful for the structure design of the mold.
