Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, and more specifically, to a hanging plate type metallurgical furnace wall brick. Background Art

[0002] A side-blown metallurgical furnace uses a method of blowing fuel gas and oxygen from the side of the converter's walls to refine molten iron into steel. In a side-blown reduction furnace with a vertical wall, when fuel or gas is injected into the furnace, a significant amount of heat is generated at the lance and in the molten pool stirring zone. The stirring of the high-temperature slag within the furnace creates a recoil force against the furnace wall, burning the lance bricks and the furnace wall. This can damage the lower wall bricks, leaving the upper wall bricks unsupported and leading to wall collapse.

[0003] Therefore, it is necessary to provide a furnace wall brick of a novel structure to solve the above-mentioned technical problems and prolong the service life of metallurgical furnaces. Utility Model Content

[0004] In view of this, the utility model proposes a hanging plate type metallurgical furnace wall brick, and its specific technical solution is as follows:

[0005] A hanging plate type metallurgical furnace wall brick comprises a furnace shell, a furnace wall copper water jacket, a hanging brick lining and slotted refractory bricks, wherein the outer vertical surface of the sleeve of the furnace wall copper water jacket is adaptively connected to the inner wall of the furnace shell, the inner vertical surface of the sleeve of the furnace wall copper water jacket is a toothed surface, and a cooling medium channel is formed in the sleeve of the furnace wall copper water jacket; each rectangular tooth of the furnace wall copper water jacket is vertically and tightly connected to a hanging brick lining corresponding to the outer side, the bottom end of the hanging brick lining is flush with the bottom surface of the corresponding rectangular tooth, and the top end is higher than the top surface of the rectangular tooth; a plurality of slotted refractory bricks are cooperatively inlaid and installed in a plurality of grooves formed on the inner vertical surface of the sleeve, and the bottom of the slotted refractory brick is provided with a strip groove for the top end of the corresponding hanging brick lining to be adaptively embedded below.

[0006] Preferably, the furnace wall copper water jacket is fixed to the furnace shell by fixing bolts.

[0007] Preferably, an expansion joint is reserved between each groove and the corresponding slotted refractory brick embedded therein.

[0008] Preferably, the brick hanging lining plate is fixed to the outer side surface of the corresponding rectangular tooth by fixing bolt 2.

[0009] Preferably, the groove depth of the strip groove is based on the ability to pull and hang the corresponding grooved refractory brick.

[0010] Compared with the existing technology, the utility model adopts a hanging plate type metallurgical furnace wall brick that is inlaid with the furnace wall copper water jacket and the slotted refractory bricks, thereby achieving the function of reserving expansion joints and cooling refractory bricks; at the same time, the utility model achieves the function of pulling and hanging refractory bricks by interlocking the hanging brick lining plate and the slotted refractory bricks. When the lower wall bricks are burned and have no support, the hanging brick lining plate can effectively pull and hang the wall bricks to prevent the furnace wall from collapsing; the utility model also allows the hanging brick lining plate to be tightly connected to the furnace wall copper water jacket, which can extend the service life of the hanging brick lining plate.

[0011] Therefore, the utility model is not only simple in material, simple in installation and masonry, but also has a long service life; at the same time, it effectively solves the problem of furnace wall collapse due to burnout of lower wall bricks, thereby extending the service life of the metallurgical furnace.

[0023] Example:

[0024] The utility model provides a hanging plate type metallurgical furnace wall brick, which can effectively solve the problem of short service life of refractory materials of a metallurgical furnace wall with a vertical furnace wall.

[0025] See Figures 1 to 6 The hanging plate type metallurgical furnace wall brick includes a furnace shell 1, a furnace wall copper water jacket 2, a hanging brick lining 3 and a slotted refractory brick 4.

[0026] The outer vertical surface of the copper water jacket 2 of the furnace wall is adapted to connect with the inner wall of the furnace shell. That is, if the furnace shell 1 of the metallurgical furnace is square, the outer vertical surface of the jacket is flat; if the furnace shell 1 of the metallurgical furnace is round, the outer vertical surface of the jacket is curved. Furthermore, more specifically, the copper water jacket 2 of the furnace wall is fixed to the furnace shell 1 with fixing bolts 1, ensuring a neat and reasonable masonry space inside the furnace.

[0027] The inner vertical surface of the copper water jacket 2 of the furnace wall is a toothed surface 21. In other words, protrusions and grooves 22 are alternately formed on the inner vertical surface of the jacket. The cooling medium channel is formed in the jacket of the copper water jacket 2 of the furnace wall. The cooling medium cools the slotted refractory bricks 4 embedded in the grooves of the water jacket through the copper material with high heat transfer efficiency.

[0028] The outer side of each rectangular tooth of the furnace wall copper water jacket 2 is vertically and tightly connected with a hanging brick lining plate 3.

[0029] The utility model allows the brick lining plate 3 to be tightly connected to the furnace wall copper water jacket 2, which can ensure that the brick lining plate 3 has a longer service life. More specifically, the brick lining plate 3 is fixed to the outer side of the corresponding rectangular tooth by fixing bolts 2 5.

[0030] Several slotted refractory bricks 4 are mounted in a plurality of grooves 22 formed on the inner vertical surface of the casing to achieve a cooling effect; and an expansion joint is reserved between each groove 22 and its corresponding embedded slotted refractory brick 4 to eliminate the temperature stress of the slotted refractory brick 4 caused by temperature changes.

[0031] The bottom end of the brick hanging liner 3 is flush with the bottom surface of the corresponding rectangular tooth, and the top end is higher than the top surface of the rectangular tooth. At the same time, the bottom of the slotted refractory brick 4 is provided with a strip groove 41 for the top end of the corresponding brick hanging liner 3 below to fit in and be embedded. The depth of the strip groove 41 is based on being able to pull and hang the corresponding slotted refractory brick 4.

[0032] The utility model achieves the function of hanging the slotted refractory bricks 4 by interlocking the brick hanging lining plate 3 with the slotted refractory bricks 4. In actual practice, when the lower wall bricks are burned and have no support, the brick hanging lining plate 3 can effectively hang the wall bricks to prevent the wall bricks from collapsing, thereby extending the service life of the metallurgical furnace.

[0033] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
