摘　　要：基于传热学及有限元理论,采用SpaceClaim三维建模软件,建立高炉直吹管三维稳态温度场有限元模型。通过有限元分析软件ANSYS Workbench,在直吹管稳定工作状态下,对温度场进行有限元数值模拟。结果表明,物性不同的耐火材料层与外钢壳之间添加一层隔热纤维棉,能大幅降低外表面温度,使直吹管获得更好的绝热性能。比较仿真数据与现场实验结果,得到外表温度的最大误差温度为2.36℃,满足工程要求。该分析为高炉直吹管设计与优化提供了方法和依据,有较好的实用价值。Based on heat transfer and finite element theory,SpaceClaim 3D modeling software is used to establish a 3D steady-state temperature field finite element model of a blast furnace blowpipe.The finite element analysis software ANSYS Workbench is used to perform finite element numerical simulation of the temperature field under the condition of steady working condition of the blowpipe.The results show that adding a layer of thermal insulation fiber cotton between the refractory material layer with different physical properties and the outer steel shell can greatly reduce the outer surface temperature and enable the blowpipe to obtain better thermal insulation performance.Comparing the simulation data with the field experiment results,the maximum error temperature of the external surface temperature is 2.36℃,which meets the engineering requirements.This analysis provides a method and basis for the design and optimization of blast furnace blowpipe,and has good practical value.
