Description

Technical Field

[0001] This application relates to the field of metallurgical technology, specifically to a copper cooling wall and blast furnace equipment. Background Technology

[0002] The blast furnace walls (including the furnace shell, cooling equipment, refractory materials, or self-condensing slag skin) are one of the key factors affecting the longevity of the blast furnace. The service life of the blast furnace walls is the result of the interaction between the furnace cooling system, refractory materials (or self-condensing slag skin), and the blast furnace smelting process. Among them, the belly, waist, and lower part of the blast furnace are located in the high-temperature and molten zone, where the operating temperature can reach above 1200℃. Under the long-term combined effect of many destructive factors such as high-temperature gas flow impact, molten slag and iron erosion, burden wear, and chemical corrosion by alkali metals and zinc, the cooling walls in this area are prone to overheating.

[0003] Modern blast furnace cooling walls have undergone decades of improvement and refinement, evolving from early cast iron cooling walls to today's copper cooling walls. Thanks to copper's high thermal conductivity, copper cooling walls can provide sufficient cooling intensity, effectively carrying away heat from the blast furnace through cooling water. A stable, self-protective slag layer forms on the hot surface of the copper cooling wall, preventing overheating of the furnace. However, some copper cooling walls in blast furnaces have experienced localized damage before reaching their expected service life. The main reason is excessive wear on the hot surface, leading to insufficient slag adhesion and frequent slag shedding. Utility Model Content

[0004] The purpose of this application is to at least solve the technical problem of excessive wear on the hot surface of existing copper cooling walls, which leads to the inability to retain slag and frequent slag shedding. This purpose is achieved through the following technical solution:

[0005] A first aspect of this application provides a copper cooling wall, including a cooling wall body and a wear-resistant structure. The cooling wall body includes a hot surface, and the hot surface is provided with a plurality of grooves protruding from the hot surface. The plurality of grooves are spaced apart along the height direction of the cooling wall body. The wear-resistant structure is used to cover the grooves. The wear-resistant structure includes first wear-resistant portions and second wear-resistant portions of unequal height. The first wear-resistant portions are provided in a plurality of locations, and the plurality of first wear-resistant portions are spaced apart along the height direction of the cooling wall body on the grooves. The second wear-resistant portions are disposed on the grooves between two adjacent first wear-resistant portions.

[0006] The copper cooling wall proposed in this application protects the groove ribs of the hot surface by covering them with a wear-resistant structure, reducing wear on the groove ribs and improving the wear resistance of the hot surface. Since the wear-resistant structure includes a first wear-resistant part and a second wear-resistant part of different heights, when the blocky furnace charge impacts the wear-resistant structure from top to bottom, the higher of the first and second wear-resistant parts is impacted first, while the lower of the first and second wear-resistant parts is shielded and protected by the higher part, reducing contact with the furnace charge and thus reducing wear. At the same time, the first and second wear-resistant parts of different heights also enhance the overall slag-coating ability of the hot surface, thereby enhancing the protection strength of the hot surface.

[0007] In some embodiments, the height of the first wear-resistant part is higher than the height of the second wear-resistant part, and along the height direction of the cooling wall body, 2 to 4 second wear-resistant parts are provided between every two adjacent first wear-resistant parts.

[0008] In some embodiments, the distance L1 from the mating surface of the top surface of the first wear-resistant part and the groove rib to the top surface of the first wear-resistant part is 30mm to 80mm.

[0009] In some embodiments, the distance L2 from the mating surface of the top surface of the second wear-resistant part and the groove rib to the top surface of the second wear-resistant part is 5mm to 20mm.

[0010] In some embodiments, the groove ribs extend in a long strip shape along the width direction of the cooling wall body.

[0011] In some embodiments, a plurality of the first wear-resistant portions or the second wear-resistant portions are provided at intervals along the extending direction of the groove rib.

[0012] In some embodiments, the copper cooling wall further includes a fastening structure, through which the first wear-resistant portion and the groove rib, and / or the second wear-resistant portion and the groove rib are fixedly connected.

[0013] In some embodiments, the wear-resistant structure is made of at least one material selected from cast iron, cast steel, wear-resistant alloy steel, and stainless steel.

[0014] In some embodiments, the first wear-resistant portion and / or the second wear-resistant portion are formed by combining at least two sub-modules.

[0015] A second aspect of this application provides a blast furnace apparatus, including the copper cooling wall of this application. Attached Figure Description

[0028] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0029] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” and “having” are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0030] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "above," "below," "inner," "outer," "end," "side," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0032] like Figures 1 to 4As shown, according to an embodiment of the present invention, a copper cooling wall is disclosed, comprising a cooling wall body 1 and a wear-resistant structure 2. The cooling wall body 1 includes a hot surface 11, and the hot surface 11 is provided with a plurality of grooves 111 protruding from the hot surface 11. The plurality of grooves 111 are spaced apart along the height direction of the cooling wall body 1. The wear-resistant structure 2 is used to cover the grooves 111. The wear-resistant structure 2 includes a first wear-resistant part 21 and a second wear-resistant part 22 of different heights. The first wear-resistant part 21 is provided with a plurality of first wear-resistant parts 21 and the plurality of first wear-resistant parts 21 are spaced apart along the height direction of the cooling wall body 1 on the grooves 111. The second wear-resistant part 22 is disposed on the grooves 111 between two adjacent first wear-resistant parts 21.

[0033] The copper cooling wall proposed in this application protects the groove ribs 111 of the hot surface 11 by covering them with a wear-resistant structure 2, thereby reducing wear and improving the wear resistance of the hot surface 11. Since the wear-resistant structure 2 includes a first wear-resistant part 21 and a second wear-resistant part 22 of different heights, when the blocky furnace charge 100 impacts the wear-resistant structure 2 from top to bottom, the higher of the first wear-resistant part 21 and the second wear-resistant part 22 is impacted by the furnace charge 100 first, while the lower of the first wear-resistant part 21 and the second wear-resistant part 22 is shielded and protected by the higher part, thus reducing contact with the furnace charge 100 and reducing wear. At the same time, the first wear-resistant part 21 and the second wear-resistant part 22, which are set at different heights, can also enhance the overall slag-coating ability of the hot surface 11, thereby enhancing the protection strength of the hot surface 11.

[0034] It should be noted that there are gaps between adjacent second wear-resistant parts 22 and between adjacent first wear-resistant parts 21 and second wear-resistant parts 22, so that after the wear-resistant structure 2 covers the groove rib 111, the hot surface 11 still has a certain copper surface area in contact with the molten iron in the furnace to achieve the cooling function. When the molten iron in the furnace is cooled and condensed into a solid state, a slag protective layer is formed in the copper surface area, which in turn protects the hot surface 11.

[0035] Specifically, the first wear-resistant part 21 and the second wear-resistant part 22 are provided with covering grooves. The first wear-resistant part 21 and the second wear-resistant part 22 cover the top surface and two sides of the groove rib 111 through the covering grooves, thereby achieving complete wrapping protection of the groove rib 111 and enhancing the overall wear resistance of the groove rib 111.

[0036] In terms of shape, the shape of the covering groove of the first wear-resistant part 21 and the second wear-resistant part 22 matches the shape of the groove rib 111. For example, if the groove rib 111 is rectangular, the covering groove of the first wear-resistant part 21 and the second wear-resistant part 22 is a rectangular groove; or, for another example, if the groove rib 111 is a dovetail shape that is narrow in the inside and wide in the outside, the covering groove of the first wear-resistant part 21 and the second wear-resistant part 22 is correspondingly set as a dovetail-shaped groove.

[0037] In this embodiment, the first wear-resistant part 21 and the second wear-resistant part 22 are snapped and fixed to the groove rib 111 by a snap-fit ​​method, but this is not a limitation. In other embodiments, the first wear-resistant part 21 and the second wear-resistant part 22 may be fixed to the groove rib 111 by other methods.

[0038] For example, such as Figure 7 As shown, in some embodiments, the copper cooling wall further includes a fastening structure 3, through which the first wear-resistant part 21 and the groove rib 111 are fixedly connected, and / or, through which the second wear-resistant part 22 and the groove rib 111 are fixedly connected.

[0039] The fastening structure 3 can be used to fix the first wear-resistant part 21 and the groove rib 111, and / or fix the second wear-resistant part 22 and the groove rib 111, thereby enhancing the connection reliability between the first wear-resistant part 21 and the groove rib 111, and / or between the second wear-resistant part 22 and the groove rib 111.

[0040] For example, fastening structure 3 can be a bolt, but it is not limited to this. Other structures that can serve a connecting function can be regarded as fastening structure 3.

[0041] Specifically, the first wear-resistant part 21 and the second wear-resistant part 22 are provided with a groove 211, and the fastening structure 3 is provided in the groove 211, thereby preventing the fastening structure 3 from being exposed and failing due to excessive wear.

[0042] Preferably, the end of the fastening structure 3 is completely located within the sink 211.

[0043] In some embodiments, the height of the first wear-resistant part 21 is higher than the height of the second wear-resistant part 22, and along the height direction of the cooling wall body 1, 2 to 4 second wear-resistant parts 22 are provided between every two adjacent first wear-resistant parts 21.

[0044] By providing 2 to 4 second wear-resistant parts 22 between each two adjacent first wear-resistant parts 21, along the height direction of the cooling wall body 1, it is beneficial to form a furnace charge 100 accumulation between two adjacent first wear-resistant parts 21 of the hot surface 11, which protects the slag skin formed on the hot surface 11, increases the protective thickness of the hot surface 11, and extends the life of the copper cooling wall.

[0045] like Figure 5 and Figure 6As shown, when some of the molten iron flows into the gap between the ribs 111 in the furnace, the hot surface 11 cools and solidifies, forming a slag protective layer to protect the copper cooling surface. At the same time, when the powdery or granular furnace charge 100 falls from top to bottom, it will fall on the first wear-resistant part 21 and accumulate to cover the slag protective layer formed inside. In other words, a first slag protective layer is formed on the hot surface 11 between the original ribs 111, and a second layer of furnace charge 100 accumulation is formed between the first wear-resistant parts 21. The second layer of furnace charge 100 accumulation covers the first slag protective layer, thus forming two protective layers on the hot surface 11, increasing the overall thickness of the hot surface 11 and enhancing the wear resistance of the hot surface 11.

[0046] Meanwhile, the first wear-resistant part 21 also plays a role in reasonably dividing the slag protective layer, dividing it into multiple modules. When the slag protective layer of some modules falls off due to gravity, it does not affect the slag protective layer of other modules, thus ensuring the protective effect of the slag protective layer on the hot surface 11. Conversely, if the slag protective layer is not divided or the spacing of the first wear-resistant part 21 is set too large, resulting in the slag protective layer being a large area, the slag protective layer is prone to large-area detachment when it falls off, causing the hot surface 11 to be directly exposed and subjected to wear.

[0047] like Figure 5 As shown, the common wear mode of the hot surface 11 of the copper cooling wall is the scouring from the furnace charge 100 from top to bottom and the irregular scouring of dust carried by the high temperature gas flow. This application can use the first wear-resistant part 21 and the second wear-resistant part 22 of different heights to be arranged at intervals, and the two material sliding surfaces formed by the height difference can slow down the wear rate and reduce the damage to the hot surface 11.

[0048] At the same time, setting the interval of the first wear-resistant part 21 within a reasonable range is also conducive to the accumulation of the furnace charge 100 between the two first wear-resistant parts 21. However, if the interval of the first wear-resistant part 21 is set too small, the obstruction of the first wear-resistant part 21 will make it difficult for the furnace charge 100 to fall between the first wear-resistant parts 21 to form an accumulation.

[0049] In this embodiment, two second wear-resistant parts 22 are provided between each two adjacent first wear-resistant parts 21, but this is not limited to this. For example, in other embodiments, three or four second wear-resistant parts 22 may also be provided between each two adjacent first wear-resistant parts 21.

[0050] In some embodiments, the distance L1 from the mating surface of the top surface of the first wear-resistant part 21 and the groove rib 111 to the top surface of the first wear-resistant part 21 is 30mm to 80mm.

[0051] By setting the distance L1 from the mating surface of the top surface of the first wear-resistant part 21 and the top surface of the groove rib 111 to the top surface of the first wear-resistant part 21 within a reasonable range, it is possible to ensure the protection of the groove rib 111 and enhance its wear resistance, while avoiding setting L1 too large to increase the material usage and the overall weight of the copper cooling wall.

[0052] The thickness of the slag protective layer is generally 10mm to 60mm. By setting the distance L1 from the mating surface of the top surface of the first wear-resistant part 21 and the top surface of the groove rib 111 to the top surface of the first wear-resistant part 21 to 30mm to 80mm, which is greater than the thickness of the slag protective layer, the slag protective layer will not cover the first wear-resistant part 21, thereby ensuring that the first wear-resistant part 21 can play a role in dividing and supporting the slag protective layer.

[0053] In some embodiments, the distance L2 from the mating surface of the top surface of the second wear-resistant part 22 and the groove rib 111 to the top surface of the second wear-resistant part 22 is 5mm to 20mm.

[0054] By setting the distance L2 from the mating surface of the top surface of the second wear-resistant part 22 and the groove rib 111 to the top surface of the second wear-resistant part 22 within a reasonable range, it is possible to ensure wear protection for the groove rib 111 and enhance its wear resistance, while avoiding excessive wear of the second wear-resistant part 22 due to an excessively small L2 setting, which would then wear down the groove rib 111.

[0055] In some embodiments, the groove rib 111 extends in a long strip shape along the width direction of the cooling wall body 1.

[0056] By extending the groove rib 111 into a long strip along the width direction of the cooling wall body 1, the overall strength of the hot surface 11 can be enhanced.

[0057] Specifically, the two ends of the groove rib 111 are connected to the two sides of the cooling wall body 1. During installation, the first wear-resistant part 21 and the second wear-resistant part 22 can be installed by inserting the groove rib 111 into the side of the cooling wall body 1. The installation is convenient and it is also convenient for subsequent replacement.

[0058] Furthermore, the groove rib 111 of the cooling wall body 1 of this application extends in the width direction in a long strip shape, eliminating the need for groove rib 111 along the height direction of the cooling wall body 1, simplifying the processing steps and saving installation costs.

[0059] In some embodiments, a plurality of first wear-resistant portions 21 or second wear-resistant portions 22 are provided at intervals along the extending direction of the groove rib 111.

[0060] By providing multiple first wear-resistant parts 21 or second wear-resistant parts 22 at intervals along the extension direction of the groove rib 111, the groove rib 111 is fully covered, enhancing wear resistance. At the same time, the intervals between the first wear-resistant parts 21 or the second wear-resistant parts 22 reserve gaps for thermal expansion and contraction, ensuring structural reliability.

[0061] In some embodiments, the wear-resistant structure 2 is made of at least one material selected from cast iron, cast steel, wear-resistant alloy steel, and stainless steel.

[0062] By making the wear-resistant structure 2 from at least one of cast iron, cast steel, wear-resistant alloy steel and stainless steel, since the slag skin is formed by the cooling of molten iron in the blast furnace, the slag skin material and the material of the wear-resistant structure 2 (cast iron and steel) have affinity, which can firmly adhere to the slag and improve the slag adhesion capacity of the hot surface 11.

[0063] Specifically, copper has better thermal conductivity than cast iron and steel, while cast iron and steel have better affinity than copper. Therefore, the exposed copper portion of the hot surface 11 has a lower temperature than the wear-resistant structure 2 made of cast iron and steel. This results in a combination of hot and cold arrangement of the copper cooling wall. That is, the wear-resistant structure 2 with better affinity is used in the groove ribs 111 of the hot surface 11 to enhance wear resistance, while the bottom of the groove of the hot surface 11 retains direct contact with the copper material with better thermal conductivity, continuing to exert the rapid slag coagulation ability of the copper cooling wall to form a stable slag protective layer. At the same time, the affinity between cast iron and steel can be used to enhance the slag adhesion ability of the wear-resistant structure 2.

[0064] The wear-resistant structure 2 is made of cast iron and steel, therefore its thermal conductivity is much higher than that of conventional refractory materials (thermal conductivity: 31 W / (m·K) for ordinary cast iron, 45 W / (m·K) for ordinary carbon steel, and 6.5 W / (m·K) for conventional refractory material SiC). The temperature of the hot surface 11 of the wear-resistant structure 2 is correspondingly much lower than that of refractory materials (approximately 400℃-450℃ lower). Lower temperatures facilitate slag formation, which is more conducive to the formation of a slag protective layer.

[0065] The toughness and compressive strength of wear-resistant structure 2 are far superior to those of conventional refractory bricks, unlike refractory bricks which are easily cracked and damaged by thermal shock and chemical corrosion in the furnace. The hardness of wear-resistant structure 2 is higher than that of the copper body (the hardness HB of common steel 20#, 35#, and 40# is 110-229, while the hardness HB of pure copper is 35-45), resulting in superior wear resistance.

[0066] In some embodiments, the first wear-resistant portion 21 and / or the second wear-resistant portion 22 are formed by combining at least two sub-modules.

[0067] By combining the first wear-resistant part 21 and / or the second wear-resistant part 22 into at least two sub-modules, modular production and assembly of the structure are achieved.

[0068] It should be noted that, as Figure 1-3 As shown in any of 5 and 6, the height direction of the cooling wall body 1 is consistent with the direction indicated by arrow A in the figure, such as... Figure 1 As shown, the width direction of the cooling wall body 1 and Figure 1 The direction indicated by arrow B in the image is consistent with the direction indicated by arrow B.

[0069] According to an embodiment of the present invention, another aspect discloses a blast furnace device, including the copper cooling wall of the present application.

[0070] Since the blast furnace equipment of this utility model includes the copper cooling wall of this utility model, the blast furnace equipment has the same technical effect as the copper cooling wall, and will not be described in detail here.

[0071] For the copper cooling walls located in the belly, waist, and lower part of the blast furnace, which are in direct contact with molten iron, a slag protective layer forms after cooling. The wear-resistant structure 2 of this application is made of cast iron or cast steel, which is more compatible with molten iron, easily adheres to form a stable slag protective layer, and is not easy to fall off. For the copper cooling walls in the middle and lower part of the blast furnace, which are more directly subjected to the scouring and wear of the furnace charge 100, the scouring can be resisted by forming a material accumulation layer on the higher first wear-resistant part 21, reducing the degree of wear on the hot surface 11.

[0072] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
