高炉炉缸炉底侵蚀预测数值模拟

Numerical simulation of erosion prediction for hearth and hearth bottom of blast furnace

介绍了用有限单元法建立的炉缸炉底侵蚀模型,及用VB编制的高炉通用的炉缸炉底温度场及应力计算软件。该软件在侵蚀线逼近问题上采用一种新的方法即单元物性转换法,大大减少了计算时间,提高了计算精度;该软件可以实现对不同结构的炉缸炉底进行温度场模拟,并实现了侵蚀线,应力应变分布线的绘制和计算结果的存储等功能。

It introduces the establishment of hearth erosion model using FEM,and the common hearth bottom temperature and stress calculation software using VB.The Software adopting a new way that the cell physical properties transformation method of erosion-line approach issue can reduce the calculation time and improve the calculation accuracy.The Software can simulate the hearth bottom temperature field for different masonry structure,different shapes,different materials,and draw erosion line,stress-strain line,store results and so on.
