Description

TECHNICAL FIELD

[0001] The utility model relates to a water beam stand column for heating furnace belongs to the technical field of steel rolling heating furnace. BACKGROUND

[0002] The steel rolling heating furnace is an important industrial furnace, which is used for heating the billet to the temperature suitable for rolling, and its main purpose is to improve the plasticity of the steel and reduce the deformation resistance, so as to facilitate the subsequent rolling process. The heating furnace generates high-temperature flame and flue gas by burning fuel, and transmits heat to the billet, so that it reaches a uniform and suitable temperature for rolling.

[0003] The water beam is mainly used for supporting the load in the horizontal direction, and its structure is usually composed of a beam and a stand column. In industrial production, especially in equipment such as heating furnaces, the water beam plays an important role. It not only supports the structure inside the heating furnace to maintain a certain position and stability, but also conducts heat to transfer the heat in the heating furnace to the water beam, so that the water beam is uniformly heated, thereby ensuring the heating effect of the heating furnace.

[0004] As a kind of water beam, the water beam stand column is vertically arranged to support the fixed beam arranged horizontally and realize water circulation. The structure mainly includes a vertical outer pipe and a core pipe arranged in the outer pipe, and a water circulation cavity is formed between the two. The water flow makes downward movement through the top port of the core pipe and enters the water circulation cavity after the bottom port of the core pipe, and the water flow makes upward movement and flows to the top port of the outer pipe. In the long-term working process, the water circulation cavity, especially the bottom of the water circulation cavity, is prone to have scale and other sediments. Since the bottom of the traditional water circulation cavity is closed, it is difficult to clean. With the increase of sediments, the bottom port of the core pipe will be inevitably blocked, thereby affecting the normal work of the water beam stand column.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. UTILITY MODEL CONTENT

[0026] The utility model will be further described in detail below in combination with the drawings and examples.

[0027] As Figure 1 shown, the scheme provides a water beam stand for heating furnace, which comprises outer tube 1 and core tube 2 that are mutually sleeved, and is characterized by comprising head tube 101, neck tube 102, body tube 103 and tail tube 104 that are mutually connected, the head tube 101 is T-shaped pipe, comprising water inlet 105 and water outlet 106; the core tube 2 comprises bevel head tube 201 and core tube body 202 that are mutually connected, the core tube body 202 is arranged at the axial position of the body tube 103, and is fixedly connected with the body tube 103 through connecting piece 5;

[0028] The bevel head tube 201 extends into the head tube 101, and the bevel of the bevel head tube 201 faces the water inlet 105, which facilitates blocking the water flow and making it enter the core tube body 202;

[0029] The core tube 2 and the outer tube 1 form water circulation cavity 3, which is used to form water circulation with the core tube cavity 204 of the core tube 2;

[0030] The bottom of the tail tube 104 is provided with tail tube convex flange 4, the bottom of the tail tube convex flange 4 is provided with tail tube convex flange cover 6 matched therewith, and the tail tube convex flange cover 6 is connected through tail tube convex flange bolt 7.

[0031] As Figure 2 shown, the water inlet 105 and water outlet 106 of the head tube 101 in the embodiment are respectively connected with fixed beam arranged horizontally, and a part of the water flow in the fixed beam will be blocked by the bevel of the bevel head tube 201 when passing through the head tube, so as to flow into the core tube cavity 204, and another part will directly flow out through the water outlet 106;

[0032] The water flow flowing into the core pipe lumen 204 will descend under the action of its own gravity, flow into the water circulation cavity 3, and make a reverse upward movement into the head pipe 101, and then a part enters the beveled opening and a part directly flows out through the water flow outlet 106; thereby forming infinite water circulation.

[0033] In the embodiment, the core pipe body 202 does not extend into the tail pipe 104, thereby ensuring that the deposits such as scale generated during long-term use are not easily blocked at the bottom port of the core pipe 2. When cleaning is required, the tail pipe convex flange cover is removed by directly removing the tail pipe convex flange bolt 7, so that the deposits inside the tail pipe can be poured and the pipe wall can be cleaned; the inside of the tail pipe can also be cleaned by a brush.

[0034] The outer pipe 1 and the core pipe 2 are both made of metal steel material, which has the characteristics of high strength, high temperature resistance and corrosion resistance.

[0035] It should be noted that in the embodiment, the diameter of the beveled head pipe 201 is smaller than the diameter of the core pipe body 202, and the beveled head pipe 201 and the core pipe body 202 are welded through the core pipe convex flange 203.

[0036] This structure not only stably connects the beveled head pipe 201 and the core pipe body 202, but also forms an inclined slope on the outside of the beveled head pipe 201 and the core pipe body 202, which is more conducive to the movement of water flow.

[0037] The core pipe convex flange 203 is placed in the head pipe 101 and the neck pipe 102.

[0038] In the embodiment, the appearance is set as a segmented head pipe 101, neck pipe 102 and body pipe 103, which not only facilitates segmented processing and connection of the appearance, but also facilitates assembly of the internal core pipe 2.

[0039] As one connection mode of the outer pipe 1 in the embodiment, the head pipe 101, the neck pipe 102, the body pipe 103 and the tail pipe 104 are connected through flanges, which facilitates subsequent disassembly and maintenance.

[0040] As another connection mode of the outer pipe 1 in the embodiment, the head pipe 101, the neck pipe 102, the body pipe 103 and the tail pipe 104 are connected through welding. After the core pipe 2 is fixedly connected with the body pipe 103, the neck pipe 102 and the head pipe 101 are respectively welded with the body pipe 103, which can effectively improve the connection strength of the outer pipe 1.

[0041] As one kind of fixed connection mode of the core pipe 2 and the outer pipe 1 in the embodiment, the connecting piece 5 is a snap ring capable of sleeving the core pipe body 202, and the outer wall of the snap ring is clamped with the inner wall of the body pipe 103; a plurality of snap ring through holes are further formed on the snap ring to facilitate the passing of water flow.

[0042] In the embodiment, when the snap ring is selected as the connecting piece between the core pipe 2 and the outer pipe 1, since the snap ring is entirely placed in the water circulation cavity 3, in order not to affect the flow of water flow, a plurality of snap ring through holes need to be formed on the snap ring.

[0043] The above is only a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can think of changes or replacements within the technical range disclosed by the utility model, which are all covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
