摘要
The chute is one of the most important parts of the blast furnace. The chute operates in a harsh environment and is continuously subjected to high temperature gas and particles. In this paper, for the working environment of chute, numerical simulation method is adopted to analyze the stress and deformation of the chute in the idle stage and the burden stage respectively. The results of the calculations are as follows: during the idle stage, the stress in the lower part of the chute are higher, with a maximum equivalent stress of 267 MPa. The lengthwise displacement of the chute outlet is the largest, with a value of 19.4 mm; the outlet sidewalls extend to both sides. The distribution of stress and deformation in the burden stage is similar to that in the idle stage, mainly affecting the inner wall of the chute. The temperature distribution and charge particles have a huge influence on the chute stress and deformation distribution. The research holds immense significance in enhancing the service life of the chute, refining its structural process, and ensuring the stable of the blast furnace.
