Abstract: The round-to-square structural component of the heating furnace flue is analyzed using the finite element software ANSYS based on an example. The calculation results are verified by referring to the analysis and design standards of pressure vessels, and the influence of the characteristic dimensions of the round-to-square structure on its structural stress level and deformation is studied. The study found that: reducing the area ratio of the upper and lower sections of the round-to-square structure can reduce the maximum stress level and structural deformation of the structure; when the height of the structural component is close to the diameter of the top circle, its maximum stress and maximum deformation are relatively low; reducing the difference in the lengths of the two sides of the bottom rectangular surface can also achieve lower stress levels and structural deformation. The results can provide references and basis for the structural design of round-to-square structural components.
