Description

Technical Field

[0001] This application relates to the field of steelmaking technology, and more specifically, to a modular, high-temperature resistant, adaptive, multi-functional operating platform for converters. Background Technology

[0002] In steelmaking, the converter "doghouse," a fully enclosed steel structure, is used to isolate the converter body from the steelmaking workshop environment to prevent furnace fire, high temperatures, dust, and molten steel from splashing out. However, existing converter "doghouse" platforms have the following technical defects:

[0003] Insufficient high-temperature durability: Traditional integral platforms are subjected to high-temperature radiation of over 1600℃ for a long time, which causes refractory materials to fall off, base plate to deform and burn, seriously affecting the service life of the equipment.

[0004] Low maintenance efficiency: After burnout, the entire machine needs to be shut down for maintenance, and the replacement cycle is usually ≥48 hours, which significantly affects the production rhythm.

[0005] Significant safety hazards: Maintenance personnel must work in a high-temperature and high-risk environment where the platform temperature exceeds 80°C, posing extremely high safety risks.

[0006] Material waste is serious: local damage requires repair of the entire structure, with a material waste rate exceeding 40%, resulting in poor economic efficiency.

[0007] To address these technical challenges, we propose a modular, high-temperature resistant, adaptive, and multifunctional operating platform for converters. Summary of the Invention

[0008] The purpose of this application is to provide a modular, high-temperature resistant, adaptive, and multifunctional operating platform for converters, which can solve the technical problems in the background art.

[0009] This application provides a modular, high-temperature resistant, adaptive, multifunctional operating platform for a converter, comprising a split modular platform, a high-temperature resistant connecting mechanism, and a slide rail system. The split modular platform consists of several functional modules and a maintenance channel module. A 5-8mm expansion joint is reserved between the functional modules, and a shape memory alloy is embedded in the expansion joint. The high-temperature resistant connecting mechanism is located at the connection point of adjacent functional modules. The slide rail system is embedded in the bottom of the maintenance channel module, which is used for the maintenance channel module to be partially moved to a safe area for maintenance without shutting down the furnace.

[0010] Furthermore, the high-temperature resistant connecting mechanism is equipped with a high-temperature resistant alloy pin and a self-locking component.

[0011] Furthermore, the high-temperature alloy pin is made of 310S stainless steel.

[0012] Furthermore, an electromagnetic slider is embedded within the slide rail system.

[0013] Furthermore, a protective layer is sprayed onto the surface of the functional module.

[0014] Furthermore, the functional modules are made of high-temperature resistant materials.

[0015] Furthermore, the connection point between the functional module and the maintenance channel module is reinforced with double bolts.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] See Figures 1-4 As shown in the figure, the converter-attached modular high-temperature adaptive multifunctional operating platform described in this embodiment includes a split modular platform 1, a high-temperature resistant connecting mechanism 2, and a slide rail system 3. The split modular platform 1 consists of several functional modules 11 and a maintenance channel module 12. A 5-8mm expansion joint 13 is reserved between the functional modules 11, and a shape memory alloy is embedded in the expansion joint 13 to alleviate the metal deformation stress caused by high-temperature operation. The high-temperature resistant connecting mechanism 2 is set at the connection of adjacent functional modules 11. The slide rail system 3 is embedded in the bottom of the maintenance channel module 12, which is used for the maintenance channel module 12 to be partially moved to a safe area for maintenance without shutting down the furnace.

[0032] This embodiment has a simple structure and reasonable design. The modular design divides the "doghouse platform" into a standardized functional module 11 and a maintenance channel module 12, which can be partially repaired, replaced or expanded. It can adapt to different converter sizes and process requirements, and can effectively reduce maintenance costs.

[0033] In addition, during use, the slide rail system 3 can be moved by an external drive mechanism to move to a safe area for maintenance without shutting down the furnace.

[0034] Based on the above embodiments, in this embodiment, the high-temperature resistant connecting mechanism 2 is provided with a high-temperature resistant alloy pin 21 and a self-locking component 22.

[0035] Specifically, the high-temperature resistant alloy pin 21 is made of 310S stainless steel.

[0036] More specifically, see Figure 3 As shown, the self-locking component 22 can be configured as a set of oppositely arranged elastic clamping structures, allowing the alloy pin to be inserted to achieve locking.

[0037] This embodiment specifically illustrates the structural configuration of the self-locking component 22, which is simple and facilitates the connection of several adjacent functional modules 11.

[0038] In some embodiments, an electromagnetic slider is embedded within the slide rail system 3.

[0039] In this embodiment, an electromagnetic slider is embedded in the slide rail system 3. During use, an external motor is connected to the electromagnetic slider through a circuit (a conduit can be installed outside the circuit to prevent damage), generating an electric driving force to move the track to both sides, thereby moving the entire platform to a safe area for maintenance and replacement. The external motor can be fixed to the platform in the maintenance and replacement area.

[0040] In some embodiments, the surface of the functional module 11 is coated with a protective layer 4.

[0041] In this embodiment, by spraying protective layer 4, the temperature resistance of the main frame of the work platform can be improved, effectively extending its service life.

[0042] In some embodiments, the functional module 11 is made of a high-temperature resistant material.

[0043] Specifically, in this embodiment, the main frame of functional module 11 can be made of high-temperature resistant stainless steel and ceramic fiber composite material in a laminated manner to improve its temperature resistance.

[0044] In some embodiments, the connection point between the functional module 11 and the maintenance channel module 12 is reinforced with double bolts.

[0045] In this embodiment, the use of double-bolt reinforcement ensures the connection's robustness and practicality. To further ensure structural stability under extreme operating conditions, the connection point between the functional module 11 and the maintenance channel module 12 can be redundantly designed.

[0046] In some alternative embodiments, standardized interfaces can be reserved on the surface of the work platform for installing a spray cooling device to cope with molten steel splashing. Wireless communication modules are provided in the standardized functional module 11 and the maintenance channel module 12 to enable status monitoring and regular maintenance via wireless communication such as LoRa.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
