[0047] refer to figure 1 and figure 2 , figure 1 It is a schematic flow chart of a distance measurement method from the vertical lower edge of the blast furnace chute to the zero material surface of the blast furnace in an embodiment of the present invention, figure 2 It is a schematic diagram of the principle of solving the distance from the vertical lower edge to the zero material surface of the blast furnace in the embodiment of the present invention.
[0048] In this embodiment, the method for measuring the distance from the vertical lower edge of the blast furnace chute to the zero material surface of the blast furnace is applied to an industrial computer, and the method includes:
[0049] Step S10: When the blast furnace chute is in the inclined suspension state, select an observation point in front of the chute inspection platform, and locate the inflection point on the blast furnace scrap surface and the inclined lower edge of the blast furnace chute.

[0076] The effective volume of a blast furnace is 3200m 3 , the length L of the chute is 3.8 meters (the total length of the chute is 4.0, but 0.2 meters are deducted after suspension), the tilting distance E is 1.1m, and the tilting angle ɑ is 43°.
[0077] 1. Select the observation point and measure:
[0078] Rotate the chute to the back of the roof manhole, perpendicular to the chute manhole;
[0079] Select a suitable observation point G in front of the chute maintenance platform;
[0080] Measured with a miniature infrared ranging and angle measuring instrument: GF=5.93m, ∠FGY=77.5°, GP=9.36m, ∠PGY=72.1°;
[0081] If point P is not covered by the chute, the inclination angle of the chute is maintained at 43°.
[0082] 2. Compile the calculation program, and substitute the measured value into the calculation program to obtain the fourth vertical distance:
[0083] 2.1 Obtain the sixth vertical distance AB based on AB=AI / sinɑ, and calculate AB=1.613 meters.
