| 摘 要： | 应用有限元法分析了某炼铁厂100t铁水罐在满载铁水工况下的温度场,在此基础上采用热-结构耦合法分析了其中所受的热应力及变形情况,并在实际工作中采用红外热像仪测量法和电阻应变片电测法进行验证。结果表明,有限元分析结果与现场测试数据的误差在合理范围内,验证了有限元分析中材料属性、边界条件的合理性及计算结果的正确性;铁水罐整体强度满足要求,但罐壁局部存在较大变形,容易使内衬产生裂缝导致铁水渗漏。

| Abstract: | The temperature field of the 100 t hot-metal ladle with full load in a certain iron-making plant was analyzed by finite element method, and the distribution of temperature, deformation and stress was investigated by thermal-structural coupling method. The real values of the ladle under working conditions were gathered by infrared thermal imaging instrument and electricity measure with resistance strain gauge. The results show that the simulation results agree well with the real values. The strength of the ladle is found to be able to satisfy the actual requirements though there is relatively large local deformation which may produce cracks on the lining, resulting in hot metal leakage. |
