Description
Technical Field
The utility model belongs to the technical field of metallurgy, and particularly relates to a water-cooling slag runner shell structure.
Background
In a blast furnace iron-making process, a slag discharging groove is an important component in a blast furnace iron-discharging platform and is used for flowing and conveying silicon oxide slag after separation of large groove slag iron in front of a furnace, the slag discharging groove is formed by a U-shaped shell and is usually made of refractory materials through pouring or ramming, under the corrosion of high-temperature slag, if the shell of the slag discharging groove is not cooled, even if the shell made of the refractory materials is still damaged, cooling water is injected from one end of the shell and then is discharged from the other end of the shell in a traditional cooling mode, the rough cooling mode not only consumes large water, but also the phenomenon that the local part far away from a water inlet and a water outlet has slow flow speed due to the uneven flow speed of the water in the shell, so that the shell is cooled and the cooling effect is low.
The Chinese patent invention specification discloses a blast furnace slag discharge groove (publication number CN103468846B) with an embedded water cooling system, and specifically discloses the following contents: this internal groove that is equipped with of cinder spout places condenser tube, and the condenser tube bending disk is rolled and is the arch bridge form the same with the body, and the body both sides are equipped with the blind hole relatively, expose condenser tube's two ports in the blind hole and connect inlet tube, outlet pipe respectively. The aim is to reduce the temperature of the environment in which the refractory material is located by the action of the cooling water flow.
However, in this cooling method, the casing cannot be directly contacted with the cooling water, so that the heat of the casing needs to be firstly conducted to the cooling water pipe and then taken away by the water flow in the cooling water pipe, and moreover, the contact between the casing and the cooling water pipe is not tight fit, and a large contact thermal resistance exists, so that the cooling effect of the cooling method is unsatisfactory.

Detailed Description
The present invention will be described in further detail below with reference to the attached drawings so as to be more clearly understood by those skilled in the art.
As shown in fig. 1, 2 and 3, the utility model comprises a shell 1, the cross section of the shell is U-shaped, a U-shaped slag channel 2 is formed on the top surface of the shell, the shell is hollow, a cavity 3 capable of containing cooling water is formed, one end of the shell is connected with a water inlet pipe 4, and the other end of the shell is connected with a water outlet pipe 5;
as shown in fig. 3, 4, 5, 6 and 7, a plurality of right partition plates 7 are uniformly arranged in the cavity of the housing along the length direction of the housing, the right partition plates are connected to the right side in the housing, a left partition plate 6 is arranged between every two adjacent right partition plates, and the left partition plates are connected to the left side in the housing.
Furthermore, the surface of the slag runner is provided with a high-temperature resistant anticorrosive layer.
Preferably, the housing is made of carbon structural steel.
Working principle of the utility model
As shown in fig. 8, the right partition board is connected to the right side in the casing, the left partition board is arranged between every two adjacent right partition boards, the left partition board is connected to the left side in the casing, the left partition board and the right partition board form a labyrinth-shaped water flow channel in the cavity of the casing, and the cooling water injected from the water inlet pipe flows in the water flow direction shown in fig. 8 and is discharged from the water outlet, which brings the following progress: firstly, the cooling water flows according to a set passage, and the flow velocity of the cooling water in the whole cavity is equal, so that the whole shell is cooled uniformly, and the shell is prevented from being cracked and damaged due to uneven cooling; secondly, the flow velocity of water is slowed down, the cooling water can fully absorb heat, the cooling water can be utilized to the maximum extent, and water saving is realized; and thirdly, the left partition plate and the right partition plate are connected with the inner wall of the shell, so that the heat dissipation area of the shell is increased, the shell can exchange heat with cooling water better, and the cooling effect is improved.
The water-cooling slag runner shell structure greatly improves the cooling effect on the slag runner shell and saves cooling water.
