Edge cooling of the cooling equipment is added, the working temperature of the edge of the cooling equipment is reduced, and abrasion or burning loss caused by too high temperature of the cooling equipment and refractory materials is avoided; the vertical ribs are arranged, so that the mechanical strength of the cast iron wall body is enhanced, and the risk of premature cracking and falling of the part is reduced; according to the embedded bricks built vertically, friction force between furnace charge and the embedded bricks is converted into pressure borne by the embedded bricks or the bottom bars instead of shearing force borne by the necks of the embedded bricks when the embedded brick grooves are transverse, so that the stress state of the embedded bricks is good during vertical building, and the stable existence time of the embedded bricks can be prolonged.

Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical engineering and relates to cooling equipment and a brick-laying structure. Background Art

[0002] Blast furnace ironmaking is a key link in steel production. Its stable operation and efficient production capacity are directly related to the benefits of the entire steel industry chain. The longevity of the blast furnace, especially the longevity of the furnace and its cooling wall in the high heat load area, is an important indicator to measure the operating efficiency and economic benefits of the blast furnace. However, despite the continuous exploration and innovation of the ironmaking industry in the design of cooling walls, such as increasing the amount of cooling water, optimizing the layout of cooling water channels, and adopting more high temperature and corrosion resistant materials, in actual applications, the effect of improving the life of the cooling wall is not significant.

[0003] Specifically, cooling staves in high heat load areas often face severe challenges. Cast iron cooling staves are prone to cracking due to excessively high local temperatures, while copper cooling staves are subject to wear, deformation, and even water leakage due to long-term extreme heat loads. One of the root causes of these problems is the insufficient cooling efficiency of the cooling stave edge, which leads to excessively high temperatures in this area, thus affecting the stability of the refractory material on the hot surface of the cooling stave, accelerating its shedding and shortening the overall service life of the cooling stave. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a cooling device and a brick-lined structure, which increases the edge cooling of the cooling device, reduces the working temperature of the edge of the cooling device, and avoids wear or burning of the cooling device and refractory materials due to excessive temperature.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling device and a brick-laying structure, including a cooling wall and vertically laid bricks, and a water pipe arranged in the cooling wall. A rib support is arranged at the bottom of the cooling wall to support the weight of the bricks and withstand the friction between the bricks and the charge; a water cooling pipe is also arranged on the edge of the cooling wall.

[0006] Optionally, a side of the cooling wall close to the bricks is further provided with vertical ribs, and the vertical ribs are provided with brick grooves for fixing the bricks.

[0007] Optionally, the cross section of the tile groove is dovetail-shaped or single-sided dovetail-shaped.

[0008] Optionally, a sealing structure is provided between the water-cooling pipe and the furnace shell, and the sealing structure is a sealing box or a bellows. A rubber pad is also provided at the contact position between the water-cooling pipe and the furnace shell.

[0009] Optionally, the water cooling pipe is completely embedded in the cooling device or half embedded in the cooling wall or surrounds the edge of the cooling wall.

[0010] Optionally, the water cooling pipe is arranged on the upper or lower bottom edge, the left or right side edge of the cooling wall, or a combination thereof.

[0011] Optionally, the water cooling pipe is a steel pipe, a copper pipe or other high temperature resistant and high thermal conductivity metal pipe.

[0012] Optionally, the water pipe is connected to the water pipe outside the furnace shell through a hose or is welded or threaded.

[0013] Optionally, the rib support and the cooling wall are integrally cast or welded.

[0014] Optionally, the vertical masonry bricks are half-bricks or full-bricks.

[0015] The beneficial effects of the utility model are as follows: the utility model increases the cooling of the edges of the cooling equipment, reduces the working temperature of the edges of the cooling equipment, and avoids wear or burning of the cooling equipment and refractory materials due to excessive temperatures; vertical ribs are arranged to enhance the mechanical strength of the cast iron wall body and reduce the risk of premature cracking and falling off of this part; the vertically laid bricks convert the friction between the charge and the bricks into pressure on the bricks or bottom ribs, rather than the shear force on the brick neck when the brick groove is horizontal, so the bricks are in a better stress state during vertical masonry, and their stable existence time can be extended.
