Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical engineering, and more specifically, to a method for constructing an integrated module of a blast furnace and its framework. Background Art

[0002] In the production process of the metallurgical industry, as the core equipment of the iron-making process, the operation efficiency and stability of a blast furnace have a decisive impact on the production capacity and product quality of the entire production line. However, with the increase in the service life of the blast furnace, equipment aging, performance decline, and the need for technological upgrading often require major repairs or in-situ demolition and reconstruction of the blast furnace. As the core equipment in the steel production process, the molten iron output of the blast furnace is directly related to the production capacity and economic benefits of the entire steel plant. Therefore, how to reduce the construction period of blast furnace demolition and new construction is of extremely important significance to steel enterprises.

[0003] Traditional blast furnace demolition and reconstruction projects usually face many challenges. First of all, the blast furnace has a complex structure and a large volume. The demolition work requires not only a high level of technology but also a large amount of manpower, material resources, and time. During the demolition process, how to ensure safe and efficient operation and avoid damage to the surrounding environment is the key to the success of the project.

[0004] Secondly, during the blast furnace reconstruction process, from foundation construction to equipment installation, each link requires fine management and strict quality control. Especially in the construction and installation stage of the blast furnace body and framework, due to the large size and heavy weight of the components, the on-site construction is difficult and risky. At the same time, it is also necessary to consider how to shorten the construction period and reduce the furnace shutdown time to minimize the impact on production.

[0005] In response to these challenges, the metallurgical industry has been exploring more efficient, safe, and economical blast furnace demolition and reconstruction solutions. In recent years, with the progress of technology and the improvement of project management level, a blast furnace overhaul process that combines off-line assembly, integral transportation, and rapid sliding installation has gradually attracted attention. However, it is only suitable for blast furnace overhauls where the old blast furnace framework can be reused. For blast furnace projects reconstructed on the original site, the blast furnace framework still needs to be installed on-line. Especially for the upper platforms, there are a large number of cross-operations during on-line work, posing a great safety risk and unable to meet the requirements of short construction period and safety for blast furnaces, becoming a bottleneck for enterprises to reduce costs and increase efficiency. Summary of the Invention

[0006] In view of this, the present invention proposes a method for constructing an integrated module of a blast furnace and its framework, aiming to solve the problem that the existing blast furnace overhaul process for in-situ reconstruction cannot meet the requirements of short construction period and safety for blast furnaces.

[0007] The present invention provides a method for constructing an integrated module of a blast furnace and its framework. The method includes the following steps: an off-line preparation step of completing the off-line assembly of the blast furnace body and its framework in the off-line assembly area; an old furnace demolition step of demolishing the old blast furnace after it is shut down and constructing a new blast furnace foundation at the demolition location; a transportation equipment positioning and reinforcement step of positioning the transportation equipment at the starting position for the overall transportation of the blast furnace body and its framework and carrying out temporary support and reinforcement; a blast furnace transportation step of fixing the off-line assembled blast furnace body and its framework to the transportation equipment and transporting the blast furnace body and its framework to directly above the new blast furnace foundation; a blast furnace positioning and connection step of placing the off-line assembled blast furnace body and its framework on the new blast furnace foundation, connecting the blast furnace body and its framework to the new blast furnace foundation, and gradually resuming production after the connection work is completed and after construction and commissioning are finished.

[0008] Further, in the above method for constructing an integrated module of a blast furnace and its framework, the off-line preparation step includes the following sub-steps: a pile foundation construction sub-step of carrying out pile foundation construction in the off-line assembly area of the blast furnace and its framework; a jig building sub-step of building a transportation jig system for the blast furnace body and its framework on the newly constructed pile foundation; an off-line assembly sub-step of carrying out the off-line assembly of the blast furnace body and its framework on the transportation jig system.

[0009] Further, in the above method for constructing an integrated module of a blast furnace and its framework, the off-line assembly sub-step specifically includes: placing a crane in the off-line assembly area of the blast furnace and its framework, installing the blast furnace body and its framework onto the transportation jig system through the crane for assembly, and setting monitoring points connected to the monitoring central control device on the transportation jig system, the blast furnace body and its framework to monitor the deformation and displacement of the transportation jig system, the blast furnace body and its framework.

[0010] Further, in the above method for constructing an integrated module of a blast furnace and its framework, before the transportation equipment positioning and reinforcement step and after the old furnace demolition step, the following step is further included: a new foundation construction step of constructing a new blast furnace foundation at the demolition location.

[0011] Further, in the above method for constructing an integrated module of a blast furnace and its framework, the new foundation construction step specifically includes: carrying out foundation excavation, steel bar binding, and concrete pouring.

[0012] Further, in the above method for constructing an integrated module of a blast furnace and its framework, during the transportation of the off-line assembled blast furnace body and its framework in the blast furnace transportation step, the deformation and displacement of the transportation jig system, the blast furnace body and its framework are monitored.

[0013] Further, for the above-mentioned overall module construction method of blast furnace and framework, the step of placing the offline-assembled blast furnace body and framework as a whole on the new blast furnace foundation specifically includes: using a GPS positioning system and a laser rangefinder to align the offline-assembled blast furnace body and framework as a whole with the new blast furnace foundation and place them on the new blast furnace foundation; using a hydraulic adjustment device to adjust the horizontal position of the transport support frame system in the offline-assembled blast furnace body and framework as a whole to be the same as that of the newly built foundation; and using a temporary fixing frame to temporarily fix the transport support frame system in the offline-assembled blast furnace body and framework as a whole.

[0014] Further, for the above-mentioned overall module construction method of blast furnace and framework, the step of fixing the offline-assembled blast furnace body and framework as a whole to the transport equipment specifically includes: jacking up the offline-assembled blast furnace body and framework as a whole to separate them from the offline-assembled foundation, and making the offline-assembled blast furnace body and framework as a whole fall onto the transport equipment and fixing them.

[0015] Further, for the above-mentioned overall module construction method of blast furnace and framework, after connecting the blast furnace body and framework to the new blast furnace foundation and before the construction and commissioning are completed, remove the transport support frame system and the temporary fixing frame in the blast furnace body and framework as a whole.

[0016] Further, for the above-mentioned overall module construction method of blast furnace and framework, the old furnace demolition step includes the following sub-steps: a furnace shutdown step of shutting down the old blast furnace and closing the equipment and valves connected to the old blast furnace; a demolition sub-step of demolishing the old blast furnace.

[0017] The method for constructing the blast furnace and its frame as an integral module provided by the present invention greatly reduces the on-site installation and commissioning time by assembling the blast furnace body and its frame offline and using large transportation equipment for overall transportation and positioning. As a result, the blast furnace shutdown time is significantly shortened, and the production efficiency is improved. Installing in a well-controlled offline environment not only optimizes the installation process but also ensures the installation quality, effectively enhancing the overall construction efficiency. At the same time, the implementation of overall transportation and rapid sliding positioning further reduces the on-site operation burden and accelerates the construction progress, making the method for constructing the blast furnace and its frame as an integral module highly efficient. Meanwhile, by assembling and transporting the blast furnace body and its frame as an integral unit offline, the standardization of blast furnace construction is achieved, reducing the complexity and difficulty of demolishing and rebuilding the blast furnace in situ, improving the construction quality and safety, and making the method for constructing the blast furnace and its frame as an integral module standardized. Moreover, by reducing the amount of high-altitude work on-site and direct construction operations in complex environments, especially the construction of each floor platform of the blast furnace frame, a large number of cross operations are reduced, providing sufficient construction work surfaces, significantly reducing the risk of safety accidents that may occur during construction, ensuring the personal safety of construction personnel, ensuring the safety of each link, and reducing the probability of safety accidents, making the method for constructing the blast furnace and its frame as an integral module safe. In addition, through offline assembly and overall transportation, working hours and manpower are reduced, and the overhaul cost is lowered. Since the construction period is shortened and the blast furnace shutdown time is reduced, the production efficiency is also improved. And by improving the efficiency of blast furnace overhaul, reducing costs, ensuring safety and quality, it provides strong support for the sustainable development of iron and steel enterprises. Generally speaking, the rapid blast furnace construction technology of the present invention has the advantages of high efficiency, modularization, safety, cost savings, environmental protection, and sustainable development compared with the prior art. It is an advanced and practical blast furnace construction technology that solves the problems that the existing blast furnace overhaul process for in-situ reconstruction cannot meet the requirements of short construction period and safety for blast furnaces.

Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0025] See Figure 1 , which is a flowchart of the construction method for the blast furnace and its frame integral module provided by the embodiment of the present invention. As shown in the figure, the method includes the following steps:

[0026] Offline preparation step S1: Complete the offline assembly of the blast furnace body and its frame in the offline assembly area of the blast furnace body and its frame.

[0027] Specifically, completing the offline assembly of the blast furnace body and its frame in the offline assembly area of the blast furnace body and its frame includes the installation and commissioning of all necessary equipment to ensure the assembly accuracy and quality.

[0028] Old furnace demolition step S2: After the old blast furnace is shut down, carry out the demolition work of the old blast furnace and construct the new blast furnace foundation at the demolition location.

[0029] Specifically, after the old blast furnace is shut down as planned and confirmed to be safe, immediately start the demolition work of the old blast furnace, adopt a scientific and reasonable demolition method, and demolish the old blast furnace as quickly as possible within the scope of safety specifications and environmental requirements.

[0030] Transport equipment positioning and reinforcement step S3: Position the transport equipment at the starting position of the overall transport of the blast furnace body and its frame and carry out temporary support and reinforcement.

[0031] Specifically, first, determine the large-scale transportation equipment, SPMT modular vehicle or skidding equipment according to the specific situation of the project (including but not limited to: weight of the transportation module, overall dimensions, transportation route, surrounding obstacles, foundation conditions, load-bearing capacity of the transportation equipment, etc.). Then, position the transportation equipment at the starting position of the overall transportation of the blast furnace and the framework, and carry out temporary support and reinforcement to ensure that it can bear the overall weight of the blast furnace and the framework and remain stable during transportation to ensure safety during the transportation process.

[0032] For the blast furnace transportation step S4, fixedly attach the offline-assembled blast furnace body and the framework as a whole to the transportation equipment, and transport the blast furnace body and the framework as a whole directly above the new blast furnace foundation.

[0033] Specifically, utilize the powerful carrying capacity of the large-scale equipment to lift the offline-assembled blast furnace body and the framework as a whole onto the large-scale transportation equipment and fix them firmly. In particular, the offline-assembled blast furnace body and the framework as a whole can be jacked up to separate them from the offline-assembled foundation, and then the offline-assembled blast furnace body and the framework as a whole can be lowered onto the transportation equipment and fixed firmly. Implement the safe transportation plan, smoothly transport the blast furnace module directly above the blast furnace foundation, and get ready for positioning. During the transportation process, constantly monitor the displacement and deformation of each control point of the transportation unit to ensure that they are within the controllable range, strictly control the speed and stability, and ensure that the blast furnace and the framework are not damaged.

After completing the connection work, and after construction and commissioning are completed, gradually resume production.

[0035] Specifically, first, the blast furnace module is accurately placed on the new blast furnace foundation by using a high-precision positioning system and a hydraulic adjustment device. Then, the blast furnace body and frame are firmly connected to the new blast furnace foundation by means of high-strength bolts or cup-shaped insertion connections, etc., to ensure overall stability and safety. After all the connection work is completed, the transportation support frame system and the temporary support structure between the transportation support frame system and the new blast furnace foundation are removed, that is, after the blast furnace body and frame are connected to the new blast furnace foundation and before the construction and commissioning are completed, the transportation support frame system and the temporary fixing frame in the whole blast furnace body and frame are removed, and the subsequent work such as equipment installation is continued. After the construction and commissioning are completed, production is gradually resumed. Among them, using a high-precision positioning system and a hydraulic adjustment device to accurately place the blast furnace module on the new blast furnace foundation can specifically include: using a GPS positioning system and a laser rangefinder to align the assembled blast furnace body and frame as a whole offline with the new blast furnace foundation and place it on the new blast furnace foundation; using a hydraulic adjustment device to adjust the horizontal position of the transportation support frame system in the assembled blast furnace body and frame as a whole offline to be the same as that of the newly built foundation; using a temporary fixing frame such as a clamping plate and other devices to temporarily fix the transportation support frame system in the assembled blast furnace body and frame as a whole offline.

[0040] Specifically, constructing the new blast furnace foundation at the demolition position of the old blast furnace specifically includes: carrying out foundation excavation, steel bar binding and concrete pouring to ensure that the construction quality meets industry standards and design requirements. Through careful organization and scientific management, strive to complete the demolition of the old blast furnace and the construction of the new blast furnace foundation in a short time, laying a solid foundation for the smooth reconstruction of the blast furnace.

[0041] Transportation equipment positioning and reinforcement step S3, position the transportation equipment at the starting position of the overall transportation of the blast furnace body and frame, and carry out temporary support and reinforcement.

[0042] Blast furnace transportation step S4, fix the assembled blast furnace body and frame as a whole to the transportation equipment, and transport the blast furnace body and frame as a whole to directly above the new blast furnace foundation.

[0043] For the blast furnace positioning and connection step S5, place the offline assembled blast furnace body and framework as a whole on the new blast furnace foundation, and connect the blast furnace body and framework to the new blast furnace foundation. After completing the connection work, and after construction and commissioning are completed, gradually resume production.

The platform beams should be able to bear the overall weight of the blast furnace body and framework.

[0048] Offline assembly sub-step S13, perform offline assembly of the blast furnace body and framework on the transport jig system.

[0049] Specifically, complete the offline assembly of the blast furnace body and framework on the jig, including the installation and commissioning of all necessary equipment to ensure the assembly accuracy and quality. Specifically, first, place a crane in the offline assembly area of the blast furnace and framework for the installation of the blast furnace body and framework; then, install the blast furnace body and framework onto the transport jig system through the crane for assembly, and set monitoring points connected to the monitoring and control device at key positions of the transport jig system, the blast furnace body and framework to monitor the deformation and displacement of the transport jig system, the blast furnace body and framework, that is, to monitor the deformation and displacement of each key point of the transport unit in real time during later transportation and make timely adjustments. Especially during the transportation process of the offline assembled blast furnace body and framework as a whole in the blast furnace transportation step S4, monitor the deformation and displacement of the transport jig system, the blast furnace body and framework.
