Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] Existing bricks have a very short lifespan in metallurgical furnaces, heating furnaces, and high-temperature liquid containers. They typically begin to break and eventually fall off completely within six to three months of operation. From then on, the cooling staves rely on cooling the molten slag to form a slag skin, which helps shape the furnace, protect the hot surface of the cooling stave, and reduce heat loss. However, the slag skin is weak and often falls off, requiring considerable time to form. During this period, the hot surface of the cooling staves reaches very high temperatures, exposing it to direct wear from the liquid slag, high-temperature airflow, and furnace charge. Cracks form and expand on the hot surface, eventually damaging the cooling staves. The short lifespan of bricks is also the primary reason for the short lifespan of cooling staves. This is because, if protected by bricks, the hot surface of the cooling staves will not exceed the maximum temperature limit, will not be directly eroded by the slag and high-temperature gas flow, and will be largely invulnerable.
[0045] The causes of brick damage have not been thoroughly studied in the industry. Commonly mentioned causes of cooling stave brick damage include: 1. Erosion of refractory materials by molten slag and furnace gases; 2. Damage caused by reactions within the refractory materials at high temperatures, such as the volume effect caused by phase changes resulting from the formation of new minerals and volatilization under vacuum; 3. Scouring and erosion of refractory materials by molten slag; 4. Thermal shock caused by repeated action of molten slag and high-temperature gases, which can cause cracking and flaking of refractory materials; 5. Damage caused by the thermal expansion of refractory materials; 6. Improper selection and matching of refractory materials; and 7. Improper use of refractory materials, such as improper masonry and baking methods.
[0046] The cooling stave designed according to the above arguments cannot last more than 15 years in certain parts of metallurgical furnaces, heating furnaces, and high-temperature liquid containers. In view of the above situation, the applicant found that the main reason for the damage of the cooling stave bricks is that the stress generated by the thermal expansion of the bricks is too high and concentrated, which leads to the damage of the bricks.
[0047] In view of the above analysis, the present invention proposes a cooling wall, which includes inlaid bricks, wherein: Figures 1 to 3 A schematic diagram of an embodiment of a brick setting provided by the present invention, Figures 4 to 6 A schematic diagram of an embodiment of a cooling wall provided by the present invention.
[0048] See also Figures 1 to 3 The tile 100 includes a mounting portion 1 and a heat receiving portion 2 sequentially distributed along a first direction. The mounting portion 1 is used to be arranged on the attachment wall 200. Along the first direction, the heat receiving portion 2 is tapered at least at its end.
[0049] In the technical solution provided by the present invention, the inlay brick 100 includes an installation part 1 and a heat-receiving part 2 distributed in sequence along a first direction. The installation part 1 is used to be arranged on the attachment wall 200. Along the first direction, the heat-receiving part 2 is tapered at least at its end. The heat-receiving part 2 faces the middle position of the high-temperature furnace body and mainly serves to bear the heat in the high-temperature furnace body. The heat-receiving part 2 is set with a variable cross-section, and a thermal deformation compensation gap is generated between the two adjacent inlay bricks 100, which reduces the risk of mutual extrusion damage between the two inlay bricks 100 after thermal deformation, and extends the service life of the inlay brick 100.
[0050] The inlay bricks 100 are arranged in the high-temperature furnace body. The inlay bricks 100 need to be in contact with the high-temperature liquid and high-temperature gas of the furnace body. The material of the inlay bricks 100 must also be a refractory material, such as ceramic bricks, corundum bricks, silicon carbide bricks, fused zirconium corundum bricks, etc.
[0051] The heat receiving portion 2 is tapered at least at its end portion, and may be tapered over the entire length of the heat receiving portion 2 or partially tapered. In one embodiment, the heat receiving portion 2 includes a first heat receiving section 21 connected to the mounting portion 1, and a second heat receiving section 22 connected to the first heat receiving section 21. The second heat receiving section 22 is tapered, and the first heat receiving section 21 can be set as a straight section to obtain a larger heating surface, which is more conducive to heat conduction.
[0052] In an embodiment of the present invention, the specific cross-sectional form of the heat receiving portion 2 is not limited. For example, it may be conical as a whole, or one side may be tapered while the thickness of the other side remains unchanged. In one embodiment, the circumferential side surface of the second heat receiving section 22 includes two first adjacent surfaces 221 arranged opposite to each other, and two second adjacent surfaces 222 located between the two first adjacent surfaces 221. In one of the tiles 100, along the first direction, the two first adjacent surfaces 221 are inclined toward each other; and / or, the two second adjacent surfaces 222 are inclined toward each other. Such an arrangement facilitates the arrangement of the heat receiving portion 2 as a tapered structure.
[0053] It should be noted that, for the tile 100, the thermal deformation is greater in the direction of larger size, and the thermal deformation is smaller in the direction of smaller size. For example, the height dimension of the tile 100 is larger, and the width dimension is relatively smaller. The height direction of the tile 100 can be reduced by a larger amplitude, and the width direction of the tile 100 can be reduced by a smaller amplitude. Alternatively, the cross-sectional size can be reduced only in the height direction of the tile 100, and the cross-sectional size cannot be reduced in the width direction of the tile 100.
[0054] Taking into account that when the stress in the tile 100 is deformed, the stress will be concentrated at the singular point, for the heated portion 2, in one embodiment, a transition connection surface is provided between the first adjacent surface 221 and the second adjacent surface 222 at adjacent positions. This arrangement reduces the risk of local stress concentration in the second heated section 22 and extends the service life of the tile 100.
[0055] In one embodiment, a transition connection surface is provided between the end surface of the second heating section 22 and the peripheral side surface of the second heating section 22 . This arrangement reduces the risk of local stress concentration in the second heating section 22 and extends the service life of the tile 100 .
[0056] In order to facilitate the installation of the tile 100, in one embodiment, the cross-sectional area of the mounting portion 1 is smaller than the cross-sectional area of the heat-receiving portion 2, so as to form a stop step surface 23 between the mounting portion 1 and the heat-receiving portion 2, so as to make the tile 100 tightly adhere to the attachment wall 200. This arrangement facilitates the installation of the tile 100.
[0057] Furthermore, in one embodiment, the mounting portion 1 is tapered along the first direction. This arrangement can well mount the tile 100 on the attachment wall 200 and reduce the risk of the tile 100 detaching from the attachment wall 200 .
[0058] The mounting portion 1 is tapered, and may be a cone-shaped mounting portion 1 as a whole, or may be a group of opposite side surfaces inclined close to each other, and another group of inclined surfaces close to each other arranged in parallel. In one embodiment, the peripheral side surface of the mounting portion 1 has two first side surfaces 11 arranged opposite to each other, and two second side surfaces 12 located between the two first side surfaces 11. In one of the tiles 100, along the first direction, the two first side surfaces 11 are inclined toward each other, or the two second side surfaces 12 are inclined toward each other. This arrangement facilitates the setting of the mounting portion 1 into a tapered structure.
[0059] Taking into account that when the stress in the tile 100 is deformed, the stress will be concentrated at the singular point, for the installation part 1, a transition connection surface is provided between the first side surface 11 and the second side surface 12 at adjacent positions. Such a setting reduces the risk of local stress concentration in the installation part 1 and extends the service life of the tile 100.
[0060] In one embodiment, a transition connection surface is provided between the end surface of the mounting portion 1 and the peripheral side surface of the mounting portion 1 . This arrangement reduces the risk of local stress concentration in the mounting portion 1 and extends the service life of the tile 100 .
[0061] It should be noted that the transition connection surface described in all the above embodiments can be a surface, such as a smooth curved surface or a straight plane, or it can be a combination of multiple surfaces, such as multiple interconnected curved surfaces with different curvature radii or multiple interconnected broken lines with different lengths, etc.
[0062] The present invention also provides a cooling wall 1000, see Figures 4 to 6 The cooling wall 1000 includes an attachment wall 200 and a plurality of inlay bricks 100. The attachment wall 200 has a hot surface. Among the plurality of inlay bricks 100, the mounting portion 1 of each inlay brick 100 is arranged on the hot surface. Since the cooling wall 1000 includes all the technical features of the inlay bricks 100 described above, it also has the technical effects brought by all the above technical features, which will not be repeated here.
[0063] It should be noted that the cooling wall 1000 in the high-temperature furnace body mainly plays the role of conducting the heat in the high-temperature furnace body. On the cooling wall 1000, a plurality of the inlay bricks 100 are arranged side by side along the height and width directions of the cooling wall 1000 to block the heat in the high-temperature furnace body through the inlay bricks 100 and conduct the heat of the inlay bricks 100 to the outside. In the embodiment of the present invention, the heat receiving part 2 of each inlay brick 100 is tapered. At this time, there will be a compensation gap between adjacent inlay bricks 100 to compensate for the thermal expansion gap of the inlay bricks 100. Refractory fillers may or may not be provided in the compensation gap. In order to reduce the impurities in the high-temperature furnace body filled in the gap, refractory fillers need to be provided in the compensation gap. On the one hand, the refractory filler reduces the impurities in the high-temperature furnace body deposited in the first compensation gap 201, and on the other hand, it has a certain deformation ability, which can compensate for the gap of the thermal deformation of the inlay brick 100. For example, the refractory filler can be made of graphite refractory material.
[0064] In addition, the mosaic tile 100 is a hexahedron. The size in the height direction of the mosaic tile 100 is larger, and the thermal deformation is larger when heated. The size in the width direction of the mosaic tile 100 is smaller, and the thermal deformation is smaller when heated. The compensation gaps in the two directions can be reasonably arranged to extend the service life of the mosaic tile 100.
[0065] Taking the two adjacent tiles 100 arranged in the height direction of the tiles 100 as a reference, specifically, in one embodiment, the first direction is the thickness direction of the attachment wall 200, the heat-receiving portion 2 includes a first heat-receiving section 21 connected to the mounting portion 1, and a second heat-receiving section 22 connected to the first heat-receiving section 21, the peripheral side surface of the second heat-receiving section 22 includes two first adjacent surfaces 221 arranged opposite to each other, and two second adjacent surfaces 222 located between the two first adjacent surfaces 221, along the first direction, the two first adjacent surfaces 221 are inclined toward each other, in one tile 100, the two first adjacent surfaces 221 are distributed along the height direction of the attachment wall 200, and in the two adjacent tiles 100 located in the height direction of the attachment wall 200, a first compensation gap 201 is formed between the first adjacent surfaces 221 of the two tiles 100, thereby reducing the risk of damage caused by the contact between the two first adjacent surfaces 221, thereby extending the service life of the tile 100.
[0066] The first heated sections 21 of the two tiles 100 can be arranged closely together or separated by a gap. In one embodiment, along the height direction of the attachment wall 200, the two adjacent tiles 100 are spaced apart. In the two adjacent tiles 100 in the height direction of the attachment wall 200, a third compensation gap 203 is formed between the first heated sections 21 of the two tiles 100. The third compensation gap 203 is connected to the first compensation gap 201. At this time, in the height direction of the tiles 100, there is a certain gap between the first heated sections 21 of the two tiles 100, which increases the distance between the two tiles 100, thereby increasing the allowable compensation gap value between the two adjacent tiles 100, thereby facilitating compensation for the thermal deformation of the tiles 100 in the height direction of the tiles 100.
[0067] Taking the two adjacent tiles 100 arranged in the width direction of the tile 100 as a reference, in one embodiment, in one tile 100, along the first direction, the two second adjacent surfaces 222 are arranged to be inclined toward each other, and in one tile 100, the two second adjacent surfaces 222 are distributed along the width direction of the attachment wall 200. In the two adjacent tiles 100 in the width direction of the attachment wall 200, a second compensation gap 202 is formed between the second adjacent surfaces 222 of the two tiles 100, which reduces the risk of damage caused by the contact between the two second adjacent surfaces 222, thereby extending the service life of the tile 100.
[0068] In the width direction of the mosaic bricks 100, a certain gap can be spaced between the first heating sections 21 of two adjacent mosaic bricks 100, and refractory fillers are filled in the gaps. In order to reduce the amount of refractory fillers used and save costs, in one embodiment, along the width direction of the attachment wall 200, the first heating sections 21 of two adjacent mosaic bricks 100 are bonded to each other. Such an arrangement facilitates the arrangement of multiple mosaic bricks 100 in sequence in the width direction of the mosaic bricks 100, thereby facilitating the forming of the cooling wall 1000.
[0069] It should be noted that a refractory filler can be provided in the above-mentioned compensation gap to reduce the impurities in the high-temperature furnace body filled in the gap. In one embodiment, a refractory filler is provided in the first compensation gap 201; and / or, a refractory filler is provided in the second compensation gap 202; and / or, a refractory filler is provided in the third compensation gap 203. On the one hand, the refractory filler reduces the impurities in the high-temperature furnace body deposited in the above-mentioned compensation gap, and on the other hand, it has a certain deformation ability, which can compensate for the gap caused by thermal deformation of the inlaid bricks 100, and has a better effect.
[0070] The specific form in which the mounting portion 1 is arranged on the attachment wall 200 is also the main content of the present invention. In one embodiment, a mounting groove 300 adapted to the mounting portion 1 is opened on the hot surface, and the mounting portion 1 is arranged in the mounting groove 300. The mounting portion 1 can be set to a tapered cross-section, and the mounting groove 300 can be set to the form of a dovetail groove. At this time, in the thickness direction of the attachment wall 200, the inlaid brick 100 is not easy to fall off and is firmly installed.
[0071] In one embodiment, the attachment wall 200 is made of metal and has good thermal conductivity. It can quickly conduct the heat of the inlaid bricks 100 to the outside, reduce the temperature of the high-temperature furnace body and the furnace wall, and improve the overall life of the high-temperature furnace body. It should be noted that the material of the attachment wall 200 can be set to cast iron, cast steel, copper or aluminum.
[0072] In one embodiment, the attachment wall 200 has a cold surface opposite to the hot surface, and the cooling wall 1000 includes a cooling pipe 400 arranged in the attachment wall 200, and a coolant flows in the cooling pipe 400. The inlet and outlet of the cooling pipe 400 are both arranged on the cold surface. The cooling pipe 400 is arranged in the attachment wall 200, and the heat of the attachment wall 200 is discharged to the outside through the cooling medium in the cooling pipe 400, which facilitates the rapid cooling of the attachment wall 200 and has a good effect.
[0073] The present invention also provides a high-temperature furnace body, which includes a cooling wall 1000. Since the high-temperature furnace body includes all the technical features of the above-mentioned cooling wall 1000, it also has the technical effects brought by all the above-mentioned technical features, which will not be described one by one here.
[0074] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
