Embodiment 1
[0031] Normal distribution matrix α in the production process of a blast furnace max =45°, when the condition of the raw material and fuel is stable, the edge airflow gradually weakens, and it is forced to gradually increase α max , and finally fixed at 42°, the furnace condition is stable. Measure the deformation of the distribution chute after replacing the distribution chute on a regular basis. The inclination angle of the assembly surface 4 of the goose head body of the distribution chute is 39.5°, and the inclination angle of the side end surface 2 of the U-shaped groove at the front end of the distribution chute is -4°. The included angle of the side end surface 2 of the U-shaped groove at the front end is 180°-(39.5°+4°)=136.5°, and the deviation is 140°-136.5°=3.5°.
Embodiment 2
[0033] A blast furnace replaced the distribution chute, and measured the deformation of the new chute. The inclination angle of the goose head body assembly surface 4 of the distribution chute is 40.5° on one side, and 40.5° on the other side, with an average of 40.5°; the inclination angle of one side of the U-shaped groove at the front end of the distribution chute is 0.5°, and the inclination angle of the other side is 0°, with an average of 0.25°; calculation The angle between the assembly surface 4 of the goose head body of the distribution chute and the U-shaped groove side end surface 2 at the front end of the distribution chute is 180°-(40.5°+0.25°)=139.2°, and the deviation is 140°-139.2°=0.8°.
