[0037] The following is combined with Figures 1 to 4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0038] A prefabricated upper furnace wall of a furnace wall, the prefabricated upper furnace wall 10 comprising two surfaces 11, two side surfaces 12, and two end surfaces 13. The two surfaces 11 are disposed opposite each other front to back, the two side surfaces 12 are disposed opposite each other left to right and are respectively disposed between the two surfaces 11, and the two end surfaces 13 are disposed opposite each other up to and down and are respectively disposed between the two surfaces 11 and the two side surfaces 12.

[0039] The two side surfaces 12 are provided with vertically extending side grooves 121, and the end surface 13 at the bottom is provided with a transversely extending end groove 131, and the notches on both sides of the end groove 131 are respectively connected to the notches at one end of the two side grooves 121;

[0040] The end surface 13 of the top is provided with a fixing portion 2, and the fixing portion 2 is connected with a fixing piece in cooperation.

[0041] The present invention provides an upper furnace wall prefabricated component 10 for a furnace wall, which is a rectangular parallelepiped prefabricated component consisting of two oppositely disposed surfaces 11, two oppositely disposed side surfaces 12, and two oppositely disposed end surfaces 13. Side grooves 121 and end grooves 131 are respectively provided on the two side surfaces 12 and one end surface, and the side grooves 121 and end grooves 131 are interconnected, forming three-sided hoisting grooves that "surround" the upper furnace wall prefabricated component 10. The hoisting grooves facilitate the hoisting of the upper furnace wall prefabricated component 10, thereby achieving the effect of quickly installing the upper furnace wall, and solving the problem that the construction process of the transmission furnace wall needs to be cast on site, which is cumbersome and time-consuming. At the same time, a fixing portion 2 is provided on the other end surface 13 of the upper furnace wall prefabricated component 10. The fixing portion 2 is used to install and fix the upper furnace wall prefabricated component 10 to other structures of the furnace, making the installation of the upper furnace wall prefabricated component 10 more stable.

[0042] Specifically, the two surfaces 11 are arranged opposite to each other front and back, the two side surfaces 12 are arranged opposite to each other left and right on both sides of the two surfaces 11, and the two end surfaces 13 are arranged opposite to each other up and down at the two ends of the two surfaces 11; the two side surfaces 12 are provided with vertically extending side grooves 121, and one of the end surfaces 13 is provided with a laterally extending end groove 131, and the two ends of the end groove 131 are connected with the two side grooves 121 on both sides to form a two-way lifting groove. In this solution, the upper furnace wall prefabricated part 10 is prepared from a mold and brought to the construction site for assembly and installation. When the upper furnace wall prefabricated part 10 needs to be installed on a certain substrate, such as a brick body, a ground or an existing wall, the lifting rope can be passed through the side groove 121 on one side to the end groove 131 on the end face, and then pulled up from the side groove 121 on the other side from bottom to top, so that the two ends of the lifting rope are limited to the lifting groove of the upper furnace wall prefabricated part 10, and the lifting rope is then connected to the two ends of the lifting rope through the lifting device of the crane, so as to lift the entire upper furnace wall prefabricated part 10; and the lifting rope is limited to the lifting groove and has a limiting effect on the lifting rope, so it is not easy to separate from the upper furnace wall prefabricated part 10. When the upper furnace wall prefabricated part 10 reaches the target position of the substrate, the end surface 13 at the bottom of the upper furnace wall prefabricated part 10 contacts the substrate, and after the upper furnace wall prefabricated part 10 is stably placed, the lifting rope can be loosened; since the end surface 13 at the bottom of the upper furnace wall prefabricated part 10 is provided with an end side groove 131, after the lifting rope is loosened, the lifting rope can freely pass through the two sides of the end side groove 131 and detach from the upper furnace wall prefabricated part 10; then, the fixing part 2 provided on the other end surface 13 of the upper furnace wall prefabricated part 10 is fixedly connected to other structures of the furnace (such as Figure 1 and 2As shown, the fixing portion 2 is located at the upper portion), so that the upper furnace wall prefabricated part 10 is initially fixed; then the upper furnace wall reinforcement member 3 is applied or installed in the side groove 121 of the upper furnace wall prefabricated part 10. The upper furnace wall reinforcement member 3 can be connected to the upper furnace wall prefabricated part 10 and the base material, and can also be connected to another wall at an adjacent position, or can also be connected to another upper furnace wall prefabricated part 10 at an adjacent position; the connection method can be glue fixing, welding, slot body clamping, clamp fixing, etc. The upper furnace wall reinforcement member 3 can be a fastener such as a screw, or a block that is clamped to the slot body of the side groove 121 of the upper furnace wall prefabricated part, or a metal structure for welding. It is worth noting that since the side groove 121 is connected to the end groove 131, when using castable as an embodiment of the upper furnace wall reinforcement member 3, the upper furnace wall reinforcement member 3 formed by the castable between the side groove 121 and the end groove 131 further increases the bonding degree and structural strength of the upper furnace wall prefabricated part 10.

[0043] Furthermore, the end surface 13 of the top is provided with the end side groove 131 , and the notches on both sides of the end side groove 131 of the end surface 13 of the top are respectively connected with the notches at the other ends of the two side grooves 121 .

[0044] By also providing end grooves 131 on the top end surface 13 and connecting them to the side grooves 121 on both sides, a complete casting channel is formed that surrounds the outer side of the upper furnace wall prefabricated component 10. When using castable material as an embodiment of the upper furnace wall reinforcement member 3 for reinforcement, the castable material can smoothly fill the entire channel, forming a continuous, seamless reinforcement layer. This continuous upper furnace wall reinforcement member 3 can significantly enhance the structural integrity of the upper furnace wall prefabricated component 10, making it more durable.

[0045] In a high-temperature furnace, the furnace wall is subject to significant thermal stress. By using castable material as the upper furnace wall reinforcement 3 to completely fill the outer surface of the upper furnace wall prefabricated member 10, a tight bond is formed between the upper furnace wall prefabricated member 10 and the upper furnace wall reinforcement 3, effectively resisting the effects of thermal stress. This bond reduces deformation or cracking of the upper furnace wall prefabricated member 10 due to thermal stress, thereby increasing its service life and safety.

[0046] Furthermore, the fixing portion 2 includes two vertical hanging bars 21 and one horizontal hanging bar 22;

[0047] The vertical hanging bars 21 are perpendicular to the end face 13 at the top, one end of the two vertical hanging bars 21 is embedded in the interior of the upper furnace wall prefabricated component 10, and the other ends of the two vertical hanging bars 21 are respectively connected to the two ends of the horizontal hanging bars 22, and the two vertical hanging bars 21 and the horizontal hanging bars 22 form a hanging bar opening 20, and the hanging bar opening 20 is exposed outside the end face 13.

[0048] The internal design of the fixing portion 2 (i.e., the vertical hanging rods 21 are pre-embedded within the upper furnace wall prefabricated member 10) reduces the workload and time required for on-site installation. Construction personnel no longer need to perform additional processing or install the fixing portion on the upper furnace wall prefabricated member 10 on-site. Instead, they simply hoist the upper furnace wall prefabricated member 10 to the designated location and securely connect it to the rest of the furnace structure using the hanging rod openings 20. This simplified installation process improves construction efficiency and reduces costs.

[0049] To further illustrate, by configuring the fixing portion 2 to be composed of a vertical hanging rib 21 and a horizontal hanging rib 22, and forming a hanging rib opening 20 exposed to the outside of the top end surface 13, the fixing portion 2 can not only cooperate with the fixing member 5 to fix the upper furnace wall prefabricated component 10, but also serve as a stable lifting structure, so that during the process of lifting the upper furnace wall prefabricated component 10, the lifting rope can be passed through the lifting groove to form a lifting structure, or the lifting rope can be passed through the hanging rib opening 20 to form a lifting structure. Lifting through the hanging rib opening 20 can provide additional support and stability during the lifting process, preventing the upper furnace wall prefabricated component 10 from tilting, shaking or falling off during the lifting process, thereby improving the safety and efficiency of the lifting.

[0050] Furthermore, the number of the fixing parts 2 is two, and the two fixing parts 2 are symmetrically distributed on the end surface 13;

[0051] The extending direction of the horizontal hanging rod 22 is the same as the extending direction of the end surface 13 .

[0052] On the one hand, by providing two symmetrically distributed fixing portions 2 on the end surface 13, the overall stability and balance of the upper furnace wall of the furnace can be significantly improved, preventing the upper furnace wall prefabricated member 10 from tilting or deforming due to uneven force, thereby ensuring the accuracy and reliability of installation. In addition, because the two fixing portions 2 are symmetrically distributed and the horizontal hanging rods 22 extend in the same direction as the end surface 13, the installer can use fixing members 5 of the same specifications to connect each fixing portion 2, thereby simplifying the installation and fixing process and improving construction efficiency.

[0053] On the other hand, when the fixing part 2 is used as a lifting structure, the crane lifts the upper furnace wall prefabricated component 10 while simultaneously hanging two fixing parts 2, so that the upper furnace wall prefabricated component 10 is more stable during the lifting and transfer process and is less likely to shake, so that the upper furnace wall prefabricated component 10 can be placed on the designated substrate more accurately.

[0054] A prefabricated assembly of a furnace wall, comprising an upper furnace wall reinforcement member 3 and the above-mentioned upper furnace wall prefabricated member of the furnace wall;

[0055] The two upper furnace wall prefabricated members 10 arranged horizontally side by side are connected by the upper furnace wall reinforcement member 3 .

[0056] By connecting two horizontally arranged upper furnace wall prefabricated members 10 via the upper furnace wall reinforcement member 3, a more stable and strong overall structure is formed. This connection method can disperse and resist the high temperature, pressure and stress from the furnace interior, improving the load-bearing capacity and stability of the entire furnace wall.

[0057] Furthermore, the prefabricated assembly design makes the installation process more efficient and convenient. Because the upper furnace wall prefabricated components 10 are prefabricated and possess a certain degree of structural strength and stability, multiple prefabricated components can be directly connected via the upper furnace wall reinforcement 3, eliminating the need for extensive on-site processing and assembly. This significantly shortens the installation period and reduces construction costs.

[0058] Specifically, during the operation of the furnace, the furnace wall will be affected by high temperature and temperature gradient, generating thermal stress. By connecting multiple upper furnace wall prefabricated parts 10 through the upper furnace wall reinforcement 3, the distribution and transmission path of thermal stress can be optimized. The upper furnace wall reinforcement 3 can absorb and disperse part of the thermal stress, reduce the relative displacement and deformation between the upper furnace wall prefabricated parts 10, and thus extend the service life of the entire furnace wall. The connection between the upper furnace wall reinforcement 3 and the upper furnace wall prefabricated part 10 is usually processed with high-temperature sealing materials or special processes to ensure the sealing and temperature resistance of the connection. This design can prevent high-temperature gas or liquid from leaking out of the connection, ensuring the normal operation and safety of the furnace.

[0059] To further illustrate, a gap is provided between two horizontally arranged upper furnace wall prefabricated members 10, and wooden boards are placed in front and behind the gap. The two wooden boards and the opposing side surfaces 12 of the two upper furnace wall prefabricated members 10 enclose a material injection channel 101, and the upper furnace wall reinforcement member 3 is confined to the material injection channel 101. The material injection channel 101 can be used to apply the upper furnace wall reinforcement member 3 from top to bottom; the upper furnace wall prefabricated members 10 are connected to each other through the upper furnace wall reinforcement member 3, and the connection method can be glue fixation, welding, slot clamping, clamping, etc. The upper furnace wall reinforcement member 3 can be a fastener such as a screw, a block clamped to the upper furnace wall reinforcement member, or a metal structure for welding. In the optimal embodiment, a cast can be used as the upper furnace wall reinforcement 3. The cast can be made of cement, resin, sand or other known casting materials. When the cast solidifies, a solid upper furnace wall reinforcement 3 is formed. This embodiment can further improve the bonding between the upper furnace wall prefabricated parts 10 and improve the fixing stability of the furnace wall.

[0060] Furthermore, the left and right ends of the upper furnace wall reinforcement 3 are respectively limited to the adjacent side grooves 121 of the two upper furnace wall prefabricated parts 10, and the front and rear ends of the upper furnace wall reinforcement 3 are respectively flush with the two front and rear surfaces 11.

[0061] By retaining the left and right ends of the upper furnace wall reinforcement member 3 within adjacent side grooves 121 of two upper furnace wall prefabricated components 10, this design significantly enhances the overall structural stability of the furnace wall. The upper furnace wall reinforcement member is directly embedded in the side grooves 121 of the upper furnace wall prefabricated components 10, forming a more secure mechanical connection. This effectively protects the furnace wall from adverse factors such as thermal stress and mechanical vibration that may occur in high-temperature environments, thereby extending the service life of the furnace wall.

[0062] The design of the front and rear ends of the upper furnace wall reinforcement 3 being flush with the front and rear surfaces 11 helps improve the sealing performance of the furnace wall. After the furnace wall is assembled, the flush end surfaces reduce the formation of gaps, preventing the leakage of high-temperature gases or molten materials through the gaps, and ensuring the stability and safety of the internal environment of the furnace.

[0063] A combined installation structure of a furnace wall, comprising a furnace shell 6, a metal fixing frame 4, a fixing member 5 and a prefabricated assembly of the furnace wall described above;

[0064] One end of the metal fixing frame 4 is connected to the furnace shell 6, and the other end of the metal fixing frame 4 is connected to the upper furnace wall reinforcement 3;

[0065] One end of the fixing member 5 is connected to the furnace shell 6 , and the other end of the fixing member 5 is detachably connected to the fixing portion 2 .

[0066] During the construction of the furnace wall, a furnace shell 6 is typically installed outside the wall, serving as the main framework of the furnace wall. One end of a fixing member 5 is welded to the furnace shell 6, while the other end is removably connected to the fixing portion 2 at the top of the upper furnace wall prefabricated member. This provides positioning and fixation for the initial installation of each upper furnace wall prefabricated member 10, ensuring that subsequent installation of upper furnace wall prefabricated members 10 will not affect previously installed upper furnace wall prefabricated members 10. After all upper furnace wall prefabricated members 10 are initially installed according to the design, the upper furnace wall reinforcement members 3 are installed.

[0067] One end of the metal fixing frame 4 is connected to the furnace shell 6, and the other end of the metal fixing frame 4 extends to the distance between the two upper furnace wall prefabricated parts 10. When the upper furnace wall reinforcement 3 is applied to the injection channel 101, the upper furnace wall reinforcement 3 can be further connected to the metal fixing frame 4. For example, when castable is used as the upper furnace wall reinforcement 3, the castable flows through the metal fixing frame 4 during flow, and then is integrated with the metal fixing frame 4 after solidification, and the upper furnace wall reinforcement 3 is connected to the metal fixing frame 4.

[0068] After the furnace wall is formed, the upper furnace wall prefabricated parts 10 are initially fixed to the furnace shell 6 by the fixing parts 5, and the upper furnace wall reinforcement parts 3 provide fixing stability between adjacent upper furnace wall prefabricated parts 10. In addition, the furnace shell 6 and the metal fixing frame 4 provide support, and the fixing stability of the upper furnace wall prefabricated parts 10 is further improved.

[0069] Furthermore, the fixing member 5 includes a screw 51 and a fastening member 52;

[0070] One end of the screw rod 51 is connected to the furnace shell 6 , and the other end of the screw rod 51 is provided with the fastening member 52 , and the fastening member 52 is fastened and connected to the fixing portion 2 .

[0071] The combination of screw 51 and fastener 52 allows for quick installation and removal of fixture 5. One end of screw 51 is welded to furnace housing 6, while the other end is fitted with fastener 52, which snaps into place with fixture 2. This connection eliminates the need for complex tools or manipulation, significantly improving installation efficiency.

[0072] Furthermore, the fastening member 52 includes two C-shaped washers 521 and two locking nuts 522 . The openings of the two C-shaped washers 521 are oppositely arranged to form a fastening cavity 520 . The fastening cavity 520 is used to accommodate the horizontal hanging rod 22 .

[0073] The two locking nuts 522 are respectively disposed on the outer sides of the two C-shaped washers 521 .

[0074] Specifically, the openings of two C-shaped washers 521 are arranged opposite each other to form a snap-fitting cavity 520, which can tightly accommodate the horizontal hanger bar 22, ensuring a tight fit between the connected components. Two locking nuts 522 are respectively set on the outside of the C-shaped washers. Tightening the locking nuts further enhances the stability of the connection and prevents loosening or falling off in environments such as high temperature and vibration.

[0075] Furthermore, the metal fixing frame 4 is a stainless steel anchor hook.

[0076] The stainless steel anchor hooks used as the metal fixing frame 4 have excellent corrosion resistance and can withstand the erosion of harsh environments such as high temperature, oxidation, acid and alkali. This means that in the high-temperature and highly corrosive working environment of the furnace, the stainless steel anchor hooks can maintain their structural integrity and stability for a long time, extending the service life of the furnace wall.

[0077] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
