Embodiment Construction
[0023] Such as Figure 1-3 As shown, the technical solution provided by the present invention is a blast furnace injection equipment in the metallurgical industry, including a distributor 1, the distributor 1 includes a main pipe 2 and a branch pipe 3, and the intersection of the main pipe 2 and the branch pipe 3 A spherical cavity is provided, and the included angle between the main pipe 2 and the branch pipe 3 is greater than 90 degrees. The distributor 1 is provided with two branch pipes 3 , and the two branch pipes 3 are respectively arranged on both sides of the central line of the main pipe 2 . The two branch pipes 3 on the distributor 1 are arranged symmetrically. The included angle between the main pipe 2 and the branch pipe 3 is 100-150°. The included angle between the two branch pipes 3 is smaller than the included angle between the main pipe 2 and the branch pipe 3 . The branch pipe 3 includes a restrictor tube 4 , and the restrictor pipe 4 is connected with the ...
