Description

Technical Field

[0001] The utility model relates to the technical field of side-blowing furnaces, in particular to a water jacket electrode protection device for a furnace top of a side-blowing furnace. Background Art

[0002] The side-blown furnace is an industrial furnace used for smelting, refining and continuous casting of metals. It achieves the heating and reaction process of the metal by blowing gas or fluid sideways. The side-blown furnace has the characteristics of high efficiency, energy saving and environmental protection. It can achieve high-quality smelting and refining of metals, and has low operating costs and maintenance requirements.

[0003] In the side-blown furnace slag pool area, the electrode hole position of the furnace top water jacket is a single tube embedded in the water jacket. During production, the temperature at the electrode is high, and the connection between the single tube and the water jacket is prone to burn out after long-term operation, causing water leakage in the water jacket and a furnace shutdown accident. Utility Model Content

[0004] Purpose of the utility model: The utility model provides a protection device for the electrode of the water jacket on the top of a side-blown furnace, which can increase the heat resistance of the electrode hole position of the water jacket on the top of the furnace.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A water jacket electrode protection device for a side-blown furnace top comprises a protective sleeve, a first butt flange is arranged on the top of the protective sleeve, and a second butt flange is arranged in the middle thereof;

[0007] A plurality of first hook nails and a plurality of second hook nails are evenly distributed in the protective sleeve, a casting layer is provided on the inner wall of the protective sleeve, and the first hook nails and the second hook nails are both located inside the casting layer.

[0008] As an improvement: the first hook nails and the second hook nails are distributed alternately.

[0009] As an improvement: the protective sleeve is inserted inside the external furnace top water jacket.

[0010] As an improvement: the protective sleeve is fixed to the top of the external furnace top water jacket through a second butt flange.

[0011] As an improvement: the first hook nail is V-shaped.

[0012] As an improvement: the second hook nail is in a straight line shape.

[0013] In summary, the utility model has the following beneficial effects:

[0014] By adding a protective sleeve at the furnace top water jacket, a plurality of first hook nails and second hook nails are arranged in the protective sleeve, and the hook nails are all located inside the casting layer, the above operation solves the problem of water jacket burning and leakage caused by high temperature at the electrode hole position of the furnace top water jacket of the side-blowing furnace, improves the service life of the furnace top water jacket, greatly reduces the number of overhauls of the side-blowing furnace, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the technical solution in the present practical embodiment, the drawings required for use in the embodiment or the description of the prior art will be briefly introduced below.

[0016] Figure 1 It is a schematic diagram of the overall structure of a water jacket electrode protection device for a side-blown furnace top;

[0017] Among them: 1. Protective sleeve; 2. First docking flange; 3. Second docking flange; 4. Casting layer; 5. External furnace top water jacket; 7. First hook nail; 8. Second hook nail. DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Please refer to Figure 1 , a water jacket electrode protection device for a side-blown furnace top, comprising a protective sleeve 1, a first butt flange 2 is provided on the top of the protective sleeve 1, and a second butt flange 3 is provided in the middle thereof;

[0020] A plurality of first hook nails 7 and a plurality of second hook nails 8 are evenly distributed in the protective sleeve 1. A casting layer 4 is provided on the inner wall of the protective sleeve 1. The first hook nails 7 and the second hook nails 8 are both located inside the casting layer 4. The first hook nails 7 and the second hook nails 8 are alternately distributed. The protective sleeve 1 is inserted inside the external furnace top water jacket 5. The protective sleeve 1 is fixed to the top of the external furnace top water jacket 5 through the second docking flange 3. The first hook nail 7 is V-shaped, and the second hook nail 8 is "I"-shaped.

[0021] In this embodiment, the protective sleeve 1 is made of a steel pipe.

[0022] In this embodiment, a protective sleeve 1 is added to the furnace top water jacket, and a plurality of first hook nails 7 and second hook nails 8 are arranged in the protective sleeve 1. The hook nails are all located inside the casting layer 4, and the casting layer 4 can play a heat insulating role. Through the above operation, the problem of water jacket burning and leakage caused by high temperature at the electrode hole position of the furnace top water jacket of the side-blowing furnace is solved, the service life of the furnace top water jacket is improved, the number of overhauls of the side-blowing furnace is greatly reduced, and the production efficiency is improved.
