结晶器在线监控集成系统的开发与应用

基于板坯连铸结晶器实测的瞬态温度数据,在对结晶器与铸坯传热行为进行反问题计算的基础上,采用并行计算方法,构造出兼顾模拟准确性与实时性的传热反问题并行计算模型,有效解决了模拟计算准确性与实时性间的矛盾,同时借助Visual C++和OpenGL技术,开发出二维、三维的结晶器传热可视化方法,建立了面向在线的结晶器传热与铸坯凝固实时计算及可视化系统。为实时提供结晶器传热与铸坯凝固状态的瞬态信息,精确把握和控制结晶器传热和连铸坯的凝固过程提供了有利支持。

Development and Application of Online Integrated Monitor System for Mould

Based on the data of transient temperatures by online measuring the con-casting mould and computing results for heat transferring behaviors between the mould and the strand by computational methods for inverse problems, the parallel computational model for inverse heat transferring problems with having the simulation accuracy and real-time characteristic is developed by application of parallel calculation method, which effectively solved the problem of conflict be- tween accuracy and real-time during analogue simulation. In addition, the visualization method for heat transferring from the 2-D or 3-D mould is created and the real-time computation ＆ visual- ization system for online heat transferring from the mould and the solidification process of a strand in the mould is established with the help of Visual C＋＋ and OpenGL. So by the real-time computation and visualization system, the real-time transient signals for monitoring the heat transferring and the solidification of the strand can be achieved.
