Description

Technical Field

[0001] This invention belongs to the field of ladle capping technology, and particularly relates to a ladle capping mechanism and its semi-full-process capping system applied to metal metallurgy. Background Technology

[0002] Currently, in order to increase economic efficiency, factories have installed ladle capping equipment. However, because the ladle cap is always hanging on the ladle, it prevents the packing edge machine from extending into the ladle for packing. Secondly, the traditional method involves adding a capping and uncapping mechanism at a designated workstation on the ground. First, an overhead crane lifts the ladle with the cap to the designated capping and uncapping position, and then the overhead crane lifts the uncapped ladle to the packing edge position for packing. After packing, the overhead crane lifts it back to the designated capping and uncapping mechanism for capping. This increases equipment investment and subsequent maintenance costs, and occupies a lot of on-site process time, greatly reducing the overall investment efficiency. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a new ladle capping mechanism and its semi-full-process capping system for use in metal metallurgy.

[0004] The technical solution adopted in this invention is as follows: a ladle capping mechanism and its semi-full-process capping system applied to metal metallurgy, comprising a track and a movable gantry, the movable gantry being slidably mounted on the upper part of the track, and a capping mechanism disposed at the lower end of the movable gantry, the capping mechanism being fixedly mounted on the lower end of the movable gantry, the capping mechanism being used to cap the ladle; and a storage mechanism disposed on the upper part of the track, the storage mechanism being slidably mounted on the upper part of the track, the storage mechanism being used to store the ladle cap.

[0005] Furthermore, the lifting mechanism includes a slider, a support frame, and a lifting component. The opposite side of the movable gantry is provided with a groove, the slider is disposed inside the groove, the support frame is fixed between the sliders, the lifting component is fixed on the upper part of the support frame, and the lower end of the movable gantry is provided with a moving wheel, which is slidably disposed on both sides of the track.

[0006] Furthermore, the storage mechanism includes a flatbed cart and a storage rack. The flatbed cart is slidably mounted on the upper part of the track, and the storage rack is fixed to the upper end of the flatbed cart. The upper part of the storage rack is provided with a slot.

[0007] Furthermore, a ladle car is provided between the mobile gantry and the storage mechanism. The ladle is moved by the ladle car to accelerate the efficiency of metal metallurgy.

[0008] The entire ladle covering process requires the installation of a ladle covering and lifting mechanism at each workstation. The more workstations a steel mill has, the more covering and lifting equipment is needed. Although installing ladle covering and lifting equipment can bring significant benefits, the more equipment there is, the greater the investment and the higher the maintenance costs will be. In addition, many steel mills have limited space, and some workstations often lack the space to install covering and lifting equipment, preventing them from implementing a ladle covering system to reduce costs, improve efficiency, and increase profits.

[0009] The semi-full-process ladle cover system only installs customized ladle cover opening and closing mechanisms at the starting position (e.g., converter position) and the ending position (e.g., RH furnace position). It also installs interchangeable customized ladle cover storage racks at both the starting and ending positions. When the ladle cover storage rack at the starting position is full, a workshop crane can be used to move the ladle cover storage rack from the converter position to the ending position, and then the ladle cover storage rack from the ending position back to the starting position. Intermediate positions, due to their fast production pace and limited space, do not have ladle cover opening and closing mechanisms installed.

[0010] After adopting the above structure, the novel beneficial effects of the present invention are as follows:

[0011] (1) The separation mechanism can quickly separate the steel ladle cover from the steel ladle at the packing edge position, which can effectively solve the problem of high packing edge frequency and fast production pace.

[0012] (2) The setting of the suspension mechanism suspends the steel ladle, which makes it easier to operate the steel ladle and improves the working efficiency of the packing line. Attached Figure Description

[0019] like Figure 1-2 As shown, a ladle capping and lifting mechanism 3 and its semi-full-process capping system applied to metal metallurgy include a track 1 and a movable gantry 2, the movable gantry 2 being slidably mounted on the upper part of the track 1. It also includes a capping mechanism 3 located at the lower end of the movable gantry 2, the capping mechanism 3 being fixed to the lower end of the movable gantry 2, the capping mechanism 3 being used to cap and lift the ladle cap; it also includes a storage mechanism 4 located on the upper part of the track 1, the storage mechanism 4 being slidably mounted on the upper part of the track 1, the storage mechanism 4 being used to store the ladle cap.

[0020] like Figure 1-2 As shown, the cover-opening mechanism 3 includes a slider 5, a support frame 6, and a cover-opening component 7. The opposite side of the movable gantry 2 is provided with a groove, the slider 5 is disposed inside the groove, the support frame 6 is fixed between the sliders 5, the cover-opening component 7 is fixed on the upper part of the support frame 6, and the lower end of the movable gantry 2 is provided with a moving wheel 8, which is slidably disposed on both sides of the track 1.

[0021] like Figure 1-2 As shown, the storage mechanism 4 includes a flatbed cart 9 and a storage rack 10. The flatbed cart 9 is slidably mounted on the upper part of the track 1, and the storage rack 10 is fixed to the upper end of the flatbed cart 9. The upper part of the storage rack 10 is provided with a slot.

[0022] Among them, a steel ladle car 11 is provided between the mobile gantry 2 and the storage mechanism 4.

[0023] In practical use, the ladle cover storage rack 10 is used to store ladle covers. The storage rack 10 is fixed to the mobile flatbed trolley 9 by a guide device. The ladle cover storage rack 10 has five layers, and each layer can hold ladle covers. The order in which ladle covers are placed on the ladle cover storage rack 10 is: first the bottom layer, then the second layer, then the third layer, and so on. Taking a cover from the storage rack 10 is exactly the opposite: first take the cover from the top layer, then take the cover from the next layer, and so on.

[0024] Normally, the mobile crane is stationary at the end of track 1. When personnel issue a cap removal command, the mobile crane automatically moves to the ladle car 11 lifting position and stops (running along track 1) according to the automatic positioning device. The mobile lifting device on the crane beam automatically moves to the designated position above the ladle cap according to the automatic positioning device (the mobile lifting device runs along the direction perpendicular to track 1, mainly to determine the spatial positioning dimensions of the ladle cap's cap shaft, using this as the positioning point on the ladle cap. The PLC processes and judges the spatial dimensions between the positioning point of the mobile lifting device and the positioning point on the ladle cap, and issues a command). Then, the mobile lifting mechanism descends, so that the hook on the lifting device descends below the ladle cap's cap shaft. Then, the mobile lifting device moves horizontally, so that the ladle cap's cap shaft is within the hook's hooking range. Finally, the mobile lifting mechanism moves upward, and the hook of the mobile lifting mechanism hooks the ladle cap's cap shaft, carrying the ladle cap upward, completing the separation of the ladle cap from the ladle, and the ladle cap removal is completed.

[0025] After the ladle cover is retrieved, the mobile trolley determines the position of the storage rack 10 through the positioning device and needs to determine which layer of the ladle cover storage rack 10 needs to be placed. Then, through PLC processing, a command is issued to make the mobile trolley carry the ladle cover to the designated layer and designated position of the ladle cover storage rack 10. The mobile lifting device descends, so that the ladle cover falls onto the designated layer of the storage rack 10, and the hook of the mobile lifting device descends below the ladle cover shaft. Then, the mobile lifting device retracts horizontally and exits outside the designated layer of the storage rack 10. The mobile lifting device rises back to the highest point, and the mobile trolley returns to the end of track 1 to wait for the next cover retrieval. The cover retrieval of the storage rack 10 is completed.

[0026] like Figure 4 As shown, the entire ladle covering process is as follows: The ladle with a cover is located at the converter ladle hoisting position and is equipped with a cover-lifting mechanism 3. The ladle car 11 moves to the cover-lifting mechanism 3 to perform the cover removal operation. The movable lifting device automatically moves to a designated position above the ladle cover according to the automatic positioning device (the movable lifting device moves along the vertical track 1, mainly determining the spatial positioning dimensions of the ladle cover's axis, using this as the positioning point on the ladle cover). Through PLC processing, the spatial dimensions between the positioning point of the movable lifting device and the positioning point on the ladle cover are determined, and instructions are issued. Then, the lifting mechanism is moved down, lowering the hook on the lifting device to below the ladle cover shaft. The lifting device is then moved horizontally until the ladle cover shaft is within the hook's reach. Finally, the lifting mechanism is moved upwards, the hook engaging the ladle cover shaft and lifting the ladle cover, thus separating the ladle cover from the ladle. The ladle car 11, now with the cover removed, travels to the converter to receive molten steel. The ladle car 11 then continues to the process section for further processing. Ladle car 11 moves to the cover-adding and uncovering mechanism 3 for cover-adding operation. The cover-adding operation is based on the same principle as the cover-adding operation. Ladle car 11 then moves to the ladle lifting position for overhead crane lifting, entering the covered ladle seat in the LF furnace. Afterward, it re-enters the cover-adding and uncovering mechanism 3 for cover removal operation. After cover removal, ladle car 11 moves to the LE furnace for steel refining, then to the process section for process treatment. After processing, it returns to the cover-adding and uncovering mechanism 3 for cover-adding, and then moves back to the ladle lifting position for overhead crane lifting, performing R... The covered ladle is placed at the H furnace ladle position and then re-enters the cover removal mechanism 3 for cover removal. After cover removal, it moves to the RH furnace for further refining of the molten steel. The ladle car 11 then moves to the process section for further processing. The ladle car 11 then moves to the cover removal mechanism 3 for cover removal. The ladle car 11 then moves to the ladle position for overhead crane lifting. The overhead crane lifts the covered ladle onto the continuous casting machine for continuous casting with the cover on. Afterward, slag removal and hot repair are performed, and the ladle returns to the cover ladle position at the converter ladle position for the next processing cycle.

[0027] like Figure 3As shown, the semi-full-process ladle covering process is as follows: The ladle with a cover is located at the converter ladle hoisting position and is equipped with a cover-lifting mechanism 3. The ladle car 11 moves to the cover-lifting mechanism 3 to perform the cover removal operation. The movable lifting device automatically moves to a designated position above the ladle cover according to the automatic positioning device (the movable lifting device moves along the vertical track 1, mainly determining the spatial positioning dimensions of the ladle cover's axis, using this as the positioning point on the ladle cover; the PLC processes the data to determine the spatial dimensions between the positioning point of the movable lifting device and the positioning point on the ladle cover, and issues a command). Then, the movable lifting mechanism descends, causing the hook on the lifting device to drop to the ladle cover. Below the ladle cover shaft, the lifting device is moved horizontally until the ladle cover shaft is within the hook's reach. Then, the lifting mechanism moves upwards, hooking the ladle cover shaft and lifting the ladle cover upwards, separating the ladle cover from the ladle. The ladle car 11, with the cover removed, moves to the converter to receive molten steel. It then continues to the process area for further processing. The ladle car 11 without the cover moves to the ladle lifting position, is lifted by an overhead crane, and then moves to the LF furnace ladle position for the uncovered ladle. Finally, the ladle car 11 moves to the LF furnace for steel refining. The ladle car 11 proceeds to the process section for further processing. After processing, it moves to the ladle lifting position for overhead crane lifting. The ladle is then placed on the RH furnace ladle position without a cover. The ladle car 11 then proceeds to the RH furnace for further refining of the molten steel. Afterward, it returns to the process section for another round of processing. Once finished, it moves back to the ladle lifting position for covering. At this point, the cover-adding / uncovering mechanism 3 returns to its original position to avoid the overhead crane lifting the ladle. The overhead crane then lifts the covered ladle onto the continuous casting machine for continuous casting. After continuous casting, the covered ladle is slag removed and hot-repaired. The ladle then proceeds to the converter ladle position with the covered ladle for the next processing cycle. The cover is then removed by the cover-adding / uncovering mechanism 3 at the converter station. Simultaneously, the ladle cover removal mechanism 3 moves the ladle cover after removal to the ladle cover storage rack 10. At this time, the storage rack 10 is empty. The ladle cover is stored on the storage rack 10. When the ladle cover storage rack 10 at the converter station is full, the full storage rack 10 is replaced by an empty storage rack 10 at the RH furnace station by a crane. The RH furnace ladle cover removal mechanism 3 moves to the storage rack 10 in advance and takes out the ladle cover from the (full) storage rack 10. The ladle cover removal mechanism 3 moves the ladle cover after removal to the ladle car 11 hoisting position in advance so that the ladle car 11 can run to the ladle hoisting position to perform the cover removal operation.

(Issuing a command), then the lifting mechanism is lowered so that the hook on the lifting device is lowered below the ladle cover shaft. Then the lifting device is moved horizontally so that the ladle cover shaft is within the hook's hooking range. Finally, the lifting mechanism is moved upward, and the hook of the lifting mechanism hooks the ladle cover shaft, lifting the ladle cover upward to complete the separation of the ladle cover from the ladle. The ladle car with the cover removed runs to the converter to receive molten steel. The ladle car continues to the process area for processing.
