A small tuyere cooling water pipe simmering tooling

Abstract

The invention discloses a small tuyere cooling water pipe simmering tool, which includes a base, a mounting rod and a guide scale, wherein the mounting rod is installed on the base, and the base is used to coaxially place the installation rod and the small tuyere sleeve on the small tuyere. On the end face where the sleeve is connected to the cooling water pipe, at least one guide scale is set on the installation rod. The end of the guide scale away from the installation rod is used to guide the bending direction of the cooling water pipe so that the cooling water pipe avoids the second set of tuyere, the large set of tuyere and the air inlet. Straight pipe; through the above-mentioned small set of cooling water pipe simmering tooling, the standardized operation of cooling water pipe simmering and bending can be realized, and the operation is simple and does not require workers to have rich experience and work skills. The simmering cooling water pipe is not easy to be unqualified due to size The rework phenomenon caused by this can realize the purpose of facilitating the assembly of the tuyere structure of the blast furnace, shortening the break time, and creating convenient conditions for the blast furnace re-airing.

Description

technical field [0001] The invention relates to the technical field of bending tooling, in particular to a small tuyere cooling water pipe simmering tooling. Background technique [0002] In the modern blast furnace smelting process, it is inevitable to need to shut off the wind to deal with the tuyeres. In the process of replacing the tuyeres, the shutdown time should be shortened as much as possible to create conditions for the recovery of the blast furnace. This requires that the spare parts of the tuyere should be made more sophisticated, and the installation of the tuyere and air ducts should not be affected by the size error of the spare parts. [0003] However, because there was no standard tool before, the cooling water pipes used as a small set of tuyeres could only be molded by experience through visual inspection during the production process. During the installation process of the small tuyere cover, because the simmering angle of the cooling water pipe is unqua...

Problems solved by technology

[0003] However, since there was no standard tool before, the cooling water pipes used as a small set of tuyeres could only be made by visual inspection and empirically during the production process.

During the installation process of the small tuyere cover, because the simmering angle of the cooling water pipe is unqualified, it is easy to cause the following three consequences: (1) The cooling water pipe of the small tuyere set leans against the edge of the second set of the tuyere, causing the small tuyere cover to be lax; (2) The cooling water pipe of the small tuyere sleeve leans against the edge of the large tuyere sleeve, causing the small tuyere sleeve to be lax.

Once the small tuyere cover or the straight air inlet pipe is not tight, only the cooling water pipe of the small tuyere cover or the spare part of the small tuyere set must be re-made at the site of the wind shutdown, which will seriously affect the installation progress of the small tuyere cover and the straight air inlet pipe, and prolong the wind shutdown. time, creating difficulties for blast furnace rewinding
