Description

Technical Field

[0001] The present application relates to the field of industrial smelting, and in particular to a furnace front transfer trolley for receiving molten iron. Background Art

[0002] In the steel manufacturing process, the effective and efficient transfer of molten iron is crucial to the optimization of the entire production process. Molten iron, that is, molten iron extracted from a blast furnace, needs to be quickly transferred from the furnace to a refining or casting facility at high temperature. Existing molten iron transfer systems usually include a furnace transfer vehicle that receives and transports molten iron to a designated location.

[0003] However, the existing technology faces many limitations in practical application. In particular, in existing factory environments with complex equipment layout or limited space, traditional molten iron transfer vehicles can only move vertically, but cannot perform necessary horizontal approach operations, making them unable to effectively approach the electric furnace to receive molten iron in some cases. This limitation not only affects the efficiency of molten iron reception, but also increases the complexity of operation and potential safety risks.

[0004] In plant renovation or expansion projects, the existing configuration of on-site equipment may not support the installation or optimization of traditional hot metal transfer systems. For example, the furnace area may be occupied by other important equipment, or the installation requirements of the hot metal transfer system were not considered in the initial design, thus limiting the access path and location of the transfer vehicle.

[0032] In the implementation manner of the present application, the furnace transfer trolley is equipped with a first moving mechanism and a second moving mechanism, allowing the trolley to move in two perpendicular planes (x direction and y direction). The first moving mechanism is responsible for the movement in the x direction, while the second moving mechanism controls the movement in the y direction. This hierarchical moving mechanism enables the trolley to flexibly adjust its position according to operational requirements, avoiding the limitation of being able to move in a single direction, and is particularly suitable for narrow or crowded production areas. The design of the roller transmission mechanism enables the molten iron ladle to move forward or backward on the roller. Through the rotation of the roller, the molten iron ladle can remain stable during the receiving, dumping or transferring process, reducing the splashing of molten iron and heat loss. The roller transmission mechanism is located above the second moving mechanism. Such a vertical layout not only saves horizontal space, but also optimizes the handling of the molten iron ladle through the rotation of the roller, thereby reducing physical labor and improving handling efficiency.

[0034] Furthermore, the second moving mechanism realizes the precise y-direction movement of the structural platform through the gear transmission structure, providing reliable support for the precise positioning of the ladle. The use of gears and racks improves the accuracy and response speed of the transmission, and the positioning displacement sensor can automatically stop the motor to prevent excessive movement;

[0035] Furthermore, the design of the roller transmission mechanism allows the ladle to move easily on the rollers, improving loading and unloading efficiency. The use of sprockets and chains ensures the synchronous rotation of multiple rollers, thereby smoothly supporting and transferring the ladle. The combination of the ladle positioning sensor and the weighing sensor not only ensures the precise position control of the ladle, but also realizes real-time weight monitoring, which is helpful for quality control and safety management.

[0036] Furthermore, the design of the heat preservation and dust removal mechanism reduces the heat loss and dust emission of the molten iron during the transfer process. The shape matching of the cover and the use of the elevator realize flexible opening and closing operations, and the use of the telescopic pipe allows the relative position of the dust collector and the transfer vehicle to change, increasing the flexibility of operation.

[0059] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0060] The furnace transfer trolley of the present application comprises a first moving mechanism 1 and a second moving mechanism 2, which are used to ensure the safe transfer and precise positioning of molten iron. The first moving mechanism 1 is controlled by a first driving motor 103, which drives the first running wheel 101 through a first coupling 104 and a first transmission shaft 105, so that the trolley moves longitudinally along the set track. The guide wheel group 107 is close to both sides of the track, which can effectively prevent the trolley from running off during movement. The positioning laser sensor 106 provides real-time feedback on the specific position of the trolley on the track to ensure that the trolley accurately reaches the predetermined position.

[0061] A second moving mechanism 2 is stacked on the first moving mechanism 1 of the trolley. The second moving mechanism 2 is provided with a gear transmission mechanism 205 controlled by a second drive motor 201, which drives the entire layer to perform precise horizontal movement through a rack. This design allows the ladle 4 to be adjusted laterally when necessary to match the position of other equipment or storage facilities above or beside it. When the trolley reaches the specified position, the second drive motor 201 of the second moving mechanism 2 is started, and the gear is driven to rotate through the second transmission shaft 206, so that the gear engages with the rack, driving the structural platform 203 and the roller transmission mechanism 3 thereon to translate in the y direction. The positioning displacement sensor 204 is triggered when the second moving mechanism 2 reaches the specified position, and the drive motor is instructed to stop running, thereby avoiding excessive movement.

[0062] The molten iron ladle 4 is placed on the roller transmission mechanism 3, and the third driving motor 306 controls the rotation of the roller 301 through the sprocket 303 and the chain 304. The molten iron ladle 4 can move forward or backward to the required position. The molten iron ladle positioning sensor 305 and the weighing sensor 307 respectively provide real-time data of the position and load of the molten iron ladle 4 to monitor and adjust the quality and position of the molten iron during the transportation process, ensuring that the molten iron ladle 4 is correctly in place and safely loaded with molten iron and loaded with the required weight of molten iron.

[0063] After the ladle 4 receives the molten iron, it returns to its original position, the ladle heat preservation and dust removal mechanism of the trolley starts to operate, and the elevator 505 starts to control the cover 501 located above the ladle 4, and the cover 501 is adjusted in height and angle through the lifting shaft 506. The ladle heat preservation and dust removal mechanism includes an initial state and a working state. In the initial state, the cover 501 covers the opening of the ladle 4; when the molten iron needs to be received, the elevator 505 is started, the cover 501 rises upward and moves away from the top of the opening of the ladle 4 as the lifting shaft 506 rotates, and the roller 301 rotates to move the ladle 4 forward; after the molten iron is received, the roller 301 rotates to return the ladle 4 to its original position, and the cover 501 covers the opening of the ladle 4 again, and the dust is sucked into the connecting pipe 502 and enters the dust collector 504 through the telescopic pipe 503 connected to the connecting pipe 502, thereby reducing air pollution in the working environment.

[0064] After the ladle 4 receives the molten iron and returns to its original position, the trolley restarts and moves to the docking position of the next process. If the ladle 4 needs to be transferred, the second moving mechanism 2 and the roller transmission mechanism 3 can be started again to drive the ladle 4 to move to a new position on the roller 301.

[0065] Through the above structural design and functional configuration, the furnace transfer trolley of the present application not only improves the efficiency and safety of the molten iron treatment process, but also significantly improves the stability and reliability of the operation through its high degree of automation and precise control. This design is suitable for changing industrial production environments, especially in steel production lines that require precise handling and positioning of high-temperature liquid metal.
