摘　　要：为了确保250t精炼钢包扩容到270t安全性,建立三维结构模型和非线性有限元模型,仿真计算钢包包壳和耐火层温度场及热应力场。计算结果表明,热应力占主导地位。最终确定了扩容钢包的优化结构型式和尺寸,选取包壳及钢结构材料。现场钢包热试和投产使用情况表明,270t扩容钢包使用效果良好,提高了生产效率。In order to expand the ladle capacity from 250 t to 270 t a three-dimensional structural model and nonlinear finite element model are established to calculate the temperature field and thermal stress field of the ladle shell and refractory layer.The simulation results show that the thermal stress is dominant.Finally,the optimized structure and size of the expanded ladle are determined.The ladle shell and steel structure materials are selected.The hot test and operation of the ladle on site show that the 270 t capacity expansion ladle is in good use and improves the production efficiency.
