Description

Technical Field

[0001] The present application relates to the technical field of metallurgical furnace slag zone cooling equipment, and in particular to a combined slag zone cooler module. Background Art

[0002] The HIsmelt molten pool smelting process is poised to become the future of smelting reduction ironmaking due to its advantages, including excellent raw material and fuel adaptability, short process flow, and simple operation. A key piece of equipment is the slag cooler (also known as the slag stave).

[0003] During the metal smelting process, several slag zone coolers are combined along the circumferential direction. The slag layer is immersed in the iron bath and its temperature can reach 1300-1600℃. The dropping of materials, gas stirring, and the shedding of the upper slag skin will all have an impact and damage on it. The operating environment is harsh, so the quality requirements for it are relatively high.

[0004] In existing technology, the cooling water channels within most slag zone coolers are formed by welding Monel tubes together to form a serpentine structure. Slag zone coolers are typically manufactured through a casting process. However, due to the large number and density of these serpentine tubes embedded within, casting can cause misalignment between the serpentine tubes and the casting, leading to significant casting difficulties and high scrap rates. The overall quality of the finished casting is low, with poor strength and the inability to eliminate casting defects. This results in high manufacturing costs and a complex production and assembly process. Utility Model Content

DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In the detailed description that follows, reference may be made to the various drawings that form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Each specific embodiment of the present application is described below in sufficient detail to enable a person of ordinary skill in the art to implement the technical solutions of the present application. It should be understood that other embodiments may be utilized or that structural, logical, or electrical changes may be made to the embodiments of the present application.

[0046] Figure 1 It is a schematic diagram of the three-dimensional structure of a combined slag zone cooler module in an embodiment of the present application. Figure 2 This is a structural view of the outer side of the inner cavity of the combined slag zone cooler module according to the embodiment of the present application. Figure 1-Figure 2As shown, the combined slag zone cooler module 100 includes a top wall 101 and a bottom wall 102, which are fixedly connected to each other, and two side walls 103. They enclose and form an inner cavity 104 with an opening. The inner cavity 104 is filled with heat-resistant casting material. The top wall 101 and the bottom wall 102 are respectively provided with cooling water channels (not shown) consisting of a water trough (not shown) and a cover plate (not shown). The top wall 101 includes a first steel layer 1011, a first copper layer 1012, and a second steel layer 1013, which are sequentially combined from the hot side 10 to the cold side 20. The first steel layer 1011 includes a cladding steel layer 1014, which is extended and bent to cover and secure the end section of the first copper layer 1012. The bottom wall 102 includes a third steel layer 1021, a second copper layer 1022, and a fourth steel layer 1023, which are sequentially combined from the hot side 10 to the cold side 20.

[0047] The combined slag zone cooler module 100 proposed in the embodiment of the present application includes a top wall 101 and a bottom wall 102 made of a copper-steel composite. When manufacturing the combined slag zone cooler module 100, a complete combined slag zone cooler module 100 can be made by assembling the top wall 101, the side wall 103 and the bottom wall 102, and the manufacturing process is simple and efficient. In addition, since the top wall 101 and the bottom wall 102 of the combined slag zone cooler module 100 of the present application are made of a copper-steel composite structure, the hot surface 10 is a steel layer, which can significantly improve the bearing strength of the slag zone cooler and prevent the upper slag skin from falling off and causing adverse effects and deformation. Furthermore, since the first steel layer 1011 includes a cladding steel layer, the hot surface 10 of the entire combined slag zone cooler module 100 is coated with a steel layer (no dead angle), so that the entire hot surface will maintain a high ability to resist adverse effects in the furnace.

[0048] Furthermore, the cold surface 20 of the top wall 101 and / or the cold surface 20 of the bottom wall 102 is provided with a strength reinforcement member for enhancing the support strength of the top wall 101 and the bottom wall 102. Figure 1 As shown, in some embodiments of the present application, the strength reinforcement is optionally a rib 106, which is vertically set between the top wall 101 and the side wall 103 and is respectively connected to the top wall 101 and the bottom wall 102. The rib 106 as a supporting structure can specifically include two forms. The first form is that the rear side surface 1061 of the rib 106 does not completely fit the cold surface 20 of the top wall 101; the second form is that Figure 1 In the form shown in , the rear side surface 1061 of the rib 106 is completely in contact with the cold surface 20 of the top wall 101. Furthermore, the number of ribs 106 can be multiple, and the multiple ribs 106 are arranged in sequence along the length direction of the connecting line 212 of the top wall 101 and the side wall 103.

[0049] Providing a strength reinforcement between the top and bottom walls can significantly enhance the bearing strength of the top and bottom walls. Designing the strength reinforcement as a ribbed structure can increase its contact area with the wall in the length direction, further enhancing the bearing strength of the top and bottom walls.

[0050] Continue to see Figure 1 As shown, the ribs 106 of the combined slag zone cooler module 100 include a first rib 1062 and a second rib 1063 disposed adjacent to each other. In a cross-sectional direction perpendicular to the inner cavity 104, the area of ​​the first rib 1062 is smaller than the area of ​​the second rib 1063 (the areas of the first rib 1062 and the second rib 1063 are different). The first ribs 1062 and the second ribs 1063 are alternately spaced along the length of the connecting line 212. The alternating arrangement of the first ribs 1062 and the second ribs 1063 can improve support strength while saving material.

[0051] Figure 3 This is a schematic diagram of the three-dimensional structure of another combined slag zone cooler module according to an embodiment of the present application. Figure 3 As shown, the strength-reinforcing member of the combined slag zone cooler module 100 is a truss beam 201, which is disposed on the second steel layer 1013 of the top wall 101 and / or the fourth steel layer 1023 of the bottom wall 102 (the truss beam 201 is connected and fixed to the second steel layer 1013 of the top wall 101 and / or the fourth steel layer 1023 of the bottom wall 102). In some embodiments of the present application, the truss beam 201 is optionally a steel structure, which can significantly enhance the supporting strength of the top wall 101 and the bottom wall 102.

[0052] In some embodiments of the present application, optionally, there are two ways to connect the cooling water channels in the top wall 101 and the cooling water channels in the bottom wall 102. The first way is that the cooling water channels respectively opened in the top wall 101 and the bottom wall 102 are connected in series with each other within the entire combined slag zone cooler module 100. For example, the water outlet of the cooling water channel of the top wall 101 is connected to the water inlet of the cooling water channel of the bottom wall 102. The second way is that the cooling water channels respectively opened in the top wall 101 and the bottom wall 102 are connected in series with each other inside their respective wall bodies. For example, the water inlet and the water outlet of the cooling water channel of the top wall 101 are arranged on the side of the top wall away from the connecting line 212 of the top wall and the bottom wall. The water inlet and outlet of the cooling water channel in the bottom wall 102 are arranged on the side of the bottom wall 102 away from the connecting line 212 between the top wall and the bottom wall, and the water outlet of the cooling water channel on the top wall 101 and the water inlet of the cooling water channel on the bottom wall 102 are not connected. In this way, the cooling water channel of the bottom wall 102 and the cooling water channel of the top wall are independent of each other, and the water outlet of the cooling water channel of the top wall 101 and the water inlet of the cooling water channel of the bottom wall 102 are not connected.

[0053] Figure 4This is a schematic diagram of the structure of a cooling water tank on the top wall of the combined slag zone cooler module according to an embodiment of the present application. Figure 1 and Figure 4 As shown, the top wall 101 includes a first cooling water trough 401 opened on the first copper layer 1012, and the second steel layer 1013 covers the first cooling water trough 401 to form a cover plate and constitutes a first cooling water channel. The cooling liquid in the first cooling water channel is introduced by a first water inlet pipe 108 penetrating the second steel layer 1013 and is discharged by a first water outlet pipe 109.

[0054] Figure 5 This is a schematic diagram of a partial component of a combined slag zone cooler module according to an embodiment of the present application. Figure 1 and Figure 5 As shown, the bottom wall 102 includes a second cooling water trough 601 opened on the second copper layer 1022, and the fourth steel layer 1023 covers the second cooling water trough 601 to form a cover plate and constitute the second cooling water trough 601. The cooling liquid in the second cooling water trough 601 is introduced by the second water inlet pipe 208 passing through the fourth steel layer 1023 and is discharged by the second water outlet pipe 209.

[0055] In the embodiments of the present application, the cooling water trough can be machined, which not only reduces costs but also improves production efficiency compared to multi-section welding. In addition, because the cooling water trough is provided in the copper layer of the wall, the overall quality can be further improved compared to the slag zone cooler formed by casting the casting body and cooling water pipes.

[0056] In the embodiment of the present application, the first cooling water tank and the second cooling water tank may optionally be in various forms, for example, Figure 4 and Figure 5The first cooling water trough 401 and the second cooling water trough 601 shown are arranged in the top wall 101 and the second cooling water trough 601 in the bottom wall 102, and both are provided in two numbers within their respective walls. Furthermore, the first cooling water trough 401 and / or the second cooling water trough 601 are composed of linear cooling water troughs 4011 and curved cooling water troughs 4012 connected to each other. The curved cooling water troughs 4012 of the two cooling water channels on the same wall are arranged alternately, and the water inlet and outlet of the same cooling water channel are both located on the side near the opening of the inner cavity 104. Furthermore, the water inlet of the same cooling water channel is connected to its linear cooling water trough 4011, and the water outlet of the same cooling water channel is connected to its curved cooling water trough 4012. After entering the water inlet of the same cooling water channel, the cooling water first passes through the linear cooling water trough 4011 and then through the curved cooling water trough 4012 before reaching the water outlet. Staggering two cooling channels on each wall significantly improves cooling capacity, while the design of linear and curved cooling troughs further enhances heat dissipation efficiency. Conversely, the inlet and outlet of the cooling channels are located on the same side, significantly increasing the cooling water contact area on each wall and improving heat dissipation efficiency.

[0057] Figure 6 This is a schematic cross-sectional view of another cooling water trough on the top wall of the combined slag zone cooler module according to an embodiment of the present application. Figure 7 A schematic cross-sectional view of another bottom wall cooling water tank of the combined slag zone cooler module according to an embodiment of the present application. Figure 6 and Figure 7 As shown, there are two first cooling water troughs 401 and two second cooling water troughs 601, and each cooling water trough is a serpentine trough. The cooling water troughs on the same wall are staggered. Figure 6 The first cooling water channel 401 shown in the figure appears interrupted in the cross-sectional view due to the curved structure of the top wall 101 and the oblique section line. However, this does not affect the continuity of the cooling water channel in the top wall 101. In addition, this application does not limit the number of cooling water channels in the top wall 101 and the bottom wall 102. Correspondingly, the number of water inlets and outlets of the cooling water channel on the same wall can also be set according to the number of cooling water channels.

[0058] Combine Figure 1 and Figure 3As shown, to connect the cooling water channels within each wall, a water inlet pipe and a water outlet pipe are provided on the wall of the combined slag zone cooler module, connected to the water inlet and water outlet of the cooling water channels, respectively. In some embodiments of the present application, optionally, the first water inlet pipe 108 and the first water outlet pipe 109 are both provided on the cold surface of the top wall 101 facing the bottom wall 102; and the second water outlet pipe 209 and the second water inlet pipe 208 are provided on the cold surface of the bottom wall 102 facing the top wall 101.

[0059] In some embodiments of the present application, optionally, if the cooling water channel in the top wall and the cooling water channel in the bottom wall are connected in series, the corresponding two ways of series connection can be: first, see Figure 1 As shown, the first water inlet pipe 108 and the first water outlet pipe 109 are both arranged on the cold surface of the top wall 101 near the opening; the second water outlet pipe 209 and the second water inlet pipe 208 are arranged on the cold surface of the bottom wall 102 near the opening. The first water outlet pipe 109 and the second water inlet pipe 208 are connected to form a water inlet connecting pipe 301, and the water inlet connecting pipe 301 is an integrally formed structure. Furthermore, the water inlet connecting pipe 301 is a straight pipe. Under this connection method, optionally, the setting method of the cooling water tank on the top wall 101 and the bottom wall 102 can refer to Figure 4 and Figure 5 .

[0060] The second one, see Figure 3 As shown, the first water outlet pipe 109 is arranged on the wall of the top wall 101 facing the opening (the top wall 101 is a curved top wall, and the position of the first water outlet pipe 109 on the wall of the top wall 101 is close to the junction of the top wall 101 and the bottom wall 102), and the second water inlet pipe 208 is arranged on the wall of the bottom wall close to the junction of the top wall 101 and the bottom wall 102. The first water outlet pipe 109 and the second water inlet pipe 208 are connected to each other. In this connection mode, optionally, the setting mode of the cooling water tank on the top wall 101 and the bottom wall 102 can refer to Figure 6 and Figure 7 The cooling water channels on corresponding positions of the top wall 101 and the bottom wall 102 (for example, located on the same side when viewed from the opening of the inner cavity 104) are connected through water inlet pipes and water outlet pipes provided on each of them.

[0061] In some embodiments of the present application, optionally, if the cooling water channel in the top wall and the cooling water channel in the bottom wall are not connected in series, correspondingly, the first water outlet pipe and the second water inlet pipe are not connected. Figure 1 As shown, the first water outlet pipe 109 and the second water inlet pipe 208 are disconnected, and the first water outlet pipe 109 is set to the same bending structure as the first water inlet pipe 108, and the second water inlet pipe 208 is also set to a bending structure with the pipe opening facing outward.

[0062] Continue to see Figure 2As shown, the top wall 101 also includes a plurality of first grooves 1018, which are formed through the first steel layer 1011 and the first copper layer 1012. The bottom wall 102 also includes a plurality of second grooves 1028, which are formed through the third steel layer 1021 and the second copper layer 1022. The design of the first and second grooves 1018, 1028, is primarily intended to accommodate the complex thermal and mechanical stresses within the blast furnace. It also helps form a stable protective slag layer on the cooling staves (each wall body can also be referred to as a cooling stave). The presence of the first and second grooves 1018, 1028 increases the contact area between the cooling staves and the blast furnace lining, improving cooling efficiency and helping to disperse stress, preventing cracking or damage to the cooling staves. Furthermore, the first and second grooves promote the adhesion of slag, forming a protective slag layer, further enhancing the durability and service life of the cooling staves. However, the design and use of the first and second grooves present certain challenges, such as the need for precise control of the groove depth and shape to avoid excessive erosion or damage.

[0063] Continue to see Figure 1 As shown, a third cooling water channel is opened in the side wall 103, and the cooling liquid in the third cooling water channel is introduced and led out respectively by a third water inlet pipe 308 and a third water outlet pipe 309 which are arranged on the wall body of the side wall 103 located in the inner cavity 104; wherein, the third cooling water channel, the first cooling water channel and the second cooling water channel are connected in series with each other in the module; or, the third cooling water channel, the first cooling water channel and the second cooling water channel are connected in series with each other inside their respective walls.

[0064] Figure 8 This is a longitudinal sectional view of a side wall of a combined slag zone cooler module according to an embodiment of the present application. Figure 1 and Figure 8 As shown, the side wall 103 is made of steel, and includes a top panel 1031, a bottom panel 1032, a side panel 1033, an inner cover plate 1034, and an outer cover plate 1035. The top panel 1031, the bottom panel 1032, and the side panel 1033 are interconnected to form a cylindrical structure, and the inner cover plate 1034 and the outer cover plate 1035 are respectively covered at both ends of the cylindrical structure to form a box-like structure.

[0065] Continue to see Figure 3 As shown, a limiting groove 310 is provided on the fourth steel layer 1023 and the second steel layer 1013 , the top panel 1031 of the side wall 103 is fixed in the limiting groove 310 of the second steel layer 1013 , and the bottom panel 1032 of the side wall 103 is fixed in the limiting groove 310 of the fourth steel layer 1023 .

[0066] In some embodiments of the present application, optionally, the top panel of the side wall is part of the second steel layer, and the bottom panel of the side wall is part of the fourth steel layer. Figure 8As shown, the top panel 1031 of the side wall 103 is part of the second steel layer 1013; the bottom panel 1032 of the side wall 103 is part of the fourth steel layer 1023. The third cooling water channel 501 located within the side wall 103 is a tubular cooling water channel consisting of a cooling water trough protruding from the box-shaped structure and an inner cover plate 1034. The design of the top panel of the side wall being part of the second steel layer and the bottom panel of the side wall being part of the fourth steel layer reduces material usage and reduces costs.

[0067] In other embodiments of the present application, the top panel of the side wall and the bottom panel of the side wall are designed separately and are not part of the corresponding steel layer. Figure 9 This is a longitudinal sectional view of another side wall of the combined slag zone cooler module of the embodiment of the present application. Figure 9 As shown, the top panel 1031 of the side wall 103 is independent of the second steel layer 1013; the bottom panel 1032 of the side wall 103 is independent of the fourth steel layer. The top panel 1031, bottom panel 1032, side panels 1033, inner cover 1034, and outer cover 1035 of the side wall 103 form a box-like structure. Multiple ribs 1036 are disposed within the box-like structure. These ribs divide the interior space of the box-like structure to form the third cooling water channel. Thus, the third cooling water channel is a box-like channel.

[0068] In the embodiment of the present application, the cooling water channel in the side wall 103 can be connected in series with the cooling water channel in the bottom wall 102, or they can be independent of each other. Figure 1 and Figure 3 As shown, the third water inlet pipe 308 is arranged at the bottom of the side wall 103 and close to the opening of the inner cavity 104, and the third water outlet pipe 309 is arranged on the top of the inner cover plate and close to the opening. The third water inlet pipe 308 and the second water outlet pipe 209 are connected to each other.

[0069] If the cooling water channel in the side wall 103 and the cooling water channel in the bottom wall 102 are independent of each other, the third water outlet pipe 309 and the third water inlet pipe 308 are both arranged at the top of the inner cover plate 1034 and close to the opening, and the third water inlet pipe 308 and the second water outlet pipe 209 are independently arranged.

[0070] It should be noted that the cooling water channels within the three walls can be connected in series, so that the water inlet of the combined slag zone cooler module is on one wall and the water outlet is on another wall. Alternatively, the cooling water channels within each wall can be independent. Alternatively, the cooling water channels of two walls can be connected in series, while the cooling water channels of the other wall can be independent. This application does not make any specific restrictions on this, and any form of connection method is within the scope of protection of this application.

[0071] In some embodiments of the present application, optionally, the first water inlet pipe, the second water inlet pipe, the third water inlet pipe, the first water outlet pipe, the second water outlet pipe and the third water outlet pipe each include an inner pipe and an outer pipe sleeved on the inner pipe, with a gap between the inner pipe and the outer pipe. Figure 1 and Figure 3 As shown, the first water inlet pipe 108, the second water inlet pipe 208, the third water inlet pipe 308, the first water outlet pipe 109, the second water outlet pipe 209, and the third water outlet pipe 309 all include an inner pipe 18 and an outer pipe 19 sleeved over the inner pipe 18, with a gap between the inner pipe 18 and the outer pipe 19. In this case, since the inner cavity 104 is filled with heat-resistant casting material, the pipes in the inner cavity 104 are configured as double-layer pipes, which can improve the bearing strength of the pipes. In addition, the outer pipe 19 can protect the inner pipe 18 used for circulating cooling liquid.

[0072] Figure 10 yes Figure 1 D-direction view of the structure shown, Figure 11 yes Figure 10 The structure shown is a cross-sectional view along AA. Figure 1 、 Figure 10 and Figure 11 As shown, the inner tube 18 of the first water inlet pipe 108 passes through the second steel layer 1013 and is connected to the first cooling water tank 401. The second water inlet pipe 208 and the second cooling water tank 601 are connected in a similar manner. Figure 12 yes Figure 1 C-direction view of the structure shown, Figure 13 yes Figure 12 The structure shown is a cross-sectional view along BB. Figure 12 and Figure 13 As shown, the inner pipe 18 of the third water outlet pipe 309 passes through the inner cover plate 1034 and is connected to the third cooling water channel 501 .

[0073] In some embodiments of the present application, the sidewalls may optionally be formed of a composite copper-steel structure. For example, the sidewalls may include, along the direction from the hot side to the cold side, a fourth steel layer, a third copper layer (not shown), and a fifth steel layer (not shown), which are sequentially composited into one structure. A serpentine third cooling water trough is provided on the third copper layer, and the fifth steel layer covers the third cooling water trough to form a third cooling water channel. The third water inlet pipe 308 and the third water outlet pipe 309 are provided through the fifth steel layer.

[0074] In some embodiments of the present application, the side wall 103 is optionally an integrally formed solid steel plate, which can significantly enhance the supporting strength of the side wall.

[0075] The side walls of the combined slag zone cooler module in the embodiment of the present application can be solid steel plates or box-type structures with cooling water channels inside, or copper-steel composite plates with similar structures to the top and bottom walls.

[0076] In summary, the combined slag zone cooler module proposed in the embodiment of the present application is composed of four parts, including a top wall (steel-copper-steel three-layer composite), a bottom wall (steel-copper-steel three-layer composite), and two side walls (water steel jackets). Each wall is provided with an independent cooling circulation channel. According to the actual water system and reasonable design, all water channels can be connected in parallel or in series to meet the heat exchange. In addition, the cooling water channels of each wall can be completed by machining, and all technical parameters can be guaranteed. The independent cooling circulation channel can reduce the difficulty of casting and increase the cooling effect at the same time.

[0077] Furthermore, the combined slag zone cooler module of the embodiment of the present application adopts a modular assembly method, and the wall bodies in different positions can be manufactured separately, and then assembled into a complete combined slag zone cooler module. A single combined slag zone cooler module can be assembled again to form an annular in-furnace cooling wall. The modules of each wall body of the combined slag zone cooler module can reduce the difficulty of production, ensure the overall quality, save manufacturing costs, and the wall bodies can be combined with each other, thereby improving production efficiency and product qualification rate. Through independent cooling circulation channels, the casting difficulty can be reduced and the cooling effect can be increased at the same time.

[0078] The above embodiments are only used to illustrate the present application and are not intended to limit the present application. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the scope of the present application. Therefore, all equivalent technical solutions should also fall within the scope disclosed in the present application.
