利用有限元ANSYS软件建立大型高炉局部模型,对炉身段不同开孔率对炉顶封罩开孔受力性能的影响进行了数值模拟。结果表明,标准荷载下,模拟条件的炉身各开孔率均使炉顶封罩孔洞周边处于弹性状态;将炉身段30%开孔率时产生的底部径向位移线性化处理后,作为炉顶封罩局部模型的径向边界约束,在标准荷载下模拟炉顶封罩的受力性能是完全可行的。
The finite element ANSYS software is used to establish the local model of large blast furnace, and the numerical simulation of the influence of the different open area ratio of the shaft section on the mechanical properties of the roof opening is carried out. The results show that under the standard load, the perforation rate of the furnace body in the simulation condition is such that the perimeter of the top cover hole is in elastic state. After linearizing the bottom radial displacement produced by 30% It is feasible to simulate the stress behavior of the top enclosure under the standard load.
