Problems solved by technology
[0003] like figure 1 and figure 2 As shown in the prior art, the contour of the material chute structure on the symmetrical section of the blast furnace distribution chute 300 is a straight line. When the blast furnace distributes material from the center to the furnace wall, the amount of material distribution increases quadratically, but the profile of the material chute gradually changes from vertical to vertical. Horizontal swing, the minimum angle with the horizontal plane is about 30°, at this time, the amount of cloth required is the largest; but the angle at which the material hits the profile of the sliding material structure also reaches a maximum of about 60°, and the impact causes the largest loss of kinetic energy and the largest deceleration of the material. The velocity component in the line direction is fur

The invention provides a blast furnace material distribution folding chute. The blast furnace material distribution folding chute comprises a chute body with a material distribution cavity, the chute body comprises a first straight line section, a second straight line section and a tilting nozzle section, and the first straight line section is used for receiving materials falling from a central throat pipe; in the length direction of the chute body, the second straight line section is arranged at the discharging end of the first straight line section, and the second straight line section is obliquely arranged towards the inner side relative to the first straight line section; and in the length direction of the chute body, the tilting nozzle section is arranged at the end, away from the first straight line section, of the second straight line section, and the tilting nozzle section is obliquely arranged towards the inner side relative to the second straight line section. Meanwhile, the invention provides blast furnace material distribution equipment which comprises the blast furnace material distribution folding chute. Compared with the prior art, the blast furnace material distribution folding chute and the blast furnace material distribution equipment provided by the invention have the advantages that the material impact force and kinetic energy loss can be reduced, the material distribution quality is improved, and the wear-resistant life of the chute is prolonged.
Description
technical field [0001] The invention relates to the technical field of blast furnace material distribution, in particular to a blast furnace material distribution folding chute and blast furnace material distribution equipment. Background technique [0002] The blast furnace is the main equipment for iron and steel smelting, and the blast furnace distribution chute is the main distribution equipment on the blast furnace. Because the blast furnace distribution chute needs to distribute the materials forward and reverse around the center line of the blast furnace, its structure must be a symmetrical structure symmetrical to the section of the blast furnace axis. [0003] like figure 1 and figure 2 As shown in the prior art, the profile of the material chute structure on the symmetrical section of the blast furnace distribution chute 300 is a straight line. When the blast furnace distributes material from the center to the furnace wall, the amount of material distribution in...
