Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically to an auxiliary device for electroslag remelting. Background Technology

[0002] In the electroslag remelting process, the addition of deoxidizers is a crucial step in ensuring the quality of metal ingots. Currently, commonly used deoxidizers typically contain components such as nickel-magnesium alloys, aluminum granules, and calcium silicate powder. The nickel-magnesium alloy raw materials are often in block form and need to be crushed to a suitable particle size before being mixed with other components. The traditional method involves manually crushing the blocky nickel-magnesium alloy using hammers or similar tools, then manually mixing it with the aluminum granules and calcium silicate powder, and finally adding the mixed deoxidizer to the molten pool using simple tools.

[0003] However, this existing technology has significant shortcomings in practical applications. On the one hand, manually crushing nickel-magnesium alloys is not only time-consuming and labor-intensive, often requiring a large amount of time for a single batch, but also results in poor particle size uniformity after crushing, easily leading to particles that are too large or too small, which in turn makes it difficult for the components to be evenly distributed during subsequent mixing. On the other hand, manual operation is not only labor-intensive, requiring operators to frequently come into contact with high-temperature environments, posing significant safety hazards, but also makes it difficult to accurately control the proportion of each component during manual mixing, resulting in a mismatch between the amount of deoxidizer added and the reaction requirements of the molten pool, ultimately affecting the purity and mechanical properties of the metal ingot after electroslag remelting. Utility Model Content

[0004] The present invention aims to provide an auxiliary device for electroslag remelting to solve the problems of uneven addition, inconsistent particle size, and high labor intensity caused by the need for manual crushing and mixing of deoxidizer during electroslag remelting.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an electroslag remelting auxiliary device, comprising a robotic arm, an electrode blank, a molten pool, a stabilizing plate, a support rod, and a guide groove. The electrode blank is connected to the robotic arm, with its bottom end located within the molten pool. The stabilizing plate is connected to one side of the molten pool, and the support rod is connected to the stabilizing plate. The guide groove is inclined towards the molten pool and mounted on the support rod. A pretreatment component is connected to one side of the guide groove. The pretreatment component includes a box, a crushing block, and a propulsion block. The box is connected to the guide groove, with an opening at one end of the box near the guide groove. The box has a channel communicating with the opening inside, and a feed inlet communicating with the channel is connected to the top of the box. The crushing block is connected to the opening and is used to crush the passing deoxidizer. The propulsion block is connected to the end of the box away from the opening.

[0006] The working principle of this utility model is as follows: When the electroslag remelting auxiliary device is working, the deoxidizer is first poured in from the feed port at the top of the box. The pusher block pushes the deoxidizer towards the opening in the channel inside the box, so that the deoxidizer is crushed when it passes the crushing block at the opening. The crushed deoxidizer falls from the opening into the inclined guide groove, and then slides down the guide groove into the molten pool. The electrode blank is connected to the robotic arm and moves with it. The stabilizing plate and support rod ensure the stability of the device. The whole process realizes the automatic crushing and conveying of the deoxidizer through the pretreatment component, which solves the shortcomings of manual handling.

[0007] The beneficial effects of this utility model are as follows: ① By utilizing the structural design of the box, feed inlet, and channel, deoxidizer (such as blocky nickel-magnesium alloy) can be introduced into the box from the feed inlet and pushed to the crushing block by the propulsion block, replacing the traditional manual crushing process and significantly reducing labor intensity; ② The crushing effect of the crushing block on the deoxidizer solves the problem of uneven particle size caused by manual crushing, making the deoxidizer particles of uniform size, which is convenient for subsequent uniform mixing with other components; ③ The pushing speed of the propulsion block pushing the deoxidizer can be controlled, and with the inclined guide groove, the crushed deoxidizer can fall evenly into the molten pool, avoiding the unevenness of manual addition; ④ The setting of the stabilizing plate and support rod ensures that the device is installed stably, and the design of the guide groove inclined towards the molten pool allows the deoxidizer to slide down by gravity, reducing power consumption and improving the reliability of the device operation; ⑤ The overall structure integrates crushing and conveying functions next to the electroslag remelting equipment, and cooperates with the movements of the robotic arm and electrode billet to realize the automated process of deoxidizer addition, improving the continuity and production efficiency of the electroslag remelting process.

[0008] Furthermore, the crushing block includes multiple gears and protrusions evenly distributed on the surface of the gears. The gears are symmetrically distributed vertically, and the protrusions between the gears mesh with each other. A motor is connected to the outside of the housing, and the output shaft of the motor passes through the housing and is connected to the center of one of the gears. The meshing of the protrusions on the gear surfaces forms a shearing and crushing structure, resulting in high crushing efficiency for blocky deoxidizers.

[0009] Furthermore, the propulsion block includes a hydraulic cylinder and a push plate. The hydraulic cylinder is connected to the end of the housing body away from the opening. The output shaft of the hydraulic cylinder passes through the housing body and is perpendicularly connected to the push plate, which is located within the channel. The thrust of the hydraulic cylinder is stable and controllable, and the pushing force can be adjusted according to the amount and hardness of the deoxidizer to ensure that the deoxidizer in the housing body moves continuously and evenly towards the crushed block, avoiding material accumulation and blockage.

[0010] Furthermore, the top of the housing is equipped with an addition box, the bottom of which is connected to the channel. This addition box facilitates the addition of other components of the deoxidizer by the operator.

[0011] Furthermore, the cross-sectional area of ​​the pusher plate is the same as that of the channel. The pusher plate can completely conform to the inner wall of the channel to push the deoxidizer, avoiding material residue or accumulation in the channel and ensuring that all the deoxidizer is pushed to the crushed block.

[0012] Furthermore, the feed inlet is located at the center of the channel. The deoxidizer falls from the center of the channel, allowing it to be evenly distributed within the channel and avoiding uneven distribution or blockage caused by bias to one side. Attached Figure Description

Detailed Implementation

[0018] The following detailed description illustrates the specific implementation method:

[0019] Example 1 is basically as shown in the appendix. Figure 1 - Appendix Figure 4As shown: An electroslag remelting auxiliary device includes a robotic arm 3, an electrode blank 2, a molten pool 1, a stabilizing disk 7, a support rod 6, and a guide groove 4. The electrode blank 2 is detachably connected to the robotic arm 3 by clamping. The bottom end of the electrode blank 2 is located inside the molten pool 1. The stabilizing disk 7 is located on the right side of the molten pool 1. The support rod 6 is fixedly connected to the stabilizing disk 7, and a vertical rod 8 is also fixedly connected to the stabilizing disk 7. The guide groove 4 is inclined towards the molten pool 1 and fixedly mounted on the support rod 6. A pretreatment component 5 is fixedly connected to one side of the guide groove 4. The pretreatment component 5 includes a housing 504, a pusher block, a first gear 505, a second gear 506, and protrusions 5051 evenly distributed on the surface of the gears. One end of the housing 504 has an opening, which is fixedly connected to the guide groove 4. The bottom end of the housing 504 is fixedly connected to the top end of the vertical rod 8, and the top end of the housing 504 has an adding box 502. The housing 504 has an opening at one end near the guide groove 4. The housing 504 has a channel communicating with the opening. The bottom of the adding box 502 communicates with the channel. The top of the housing 504 is fixedly connected to a feed inlet 503 communicating with the channel. The feed inlet is located at the center of the channel. The first gear 505 and the second gear 506 are symmetrically arranged at the opening, and the protrusions 5051 between the surfaces of the two gears mesh with each other. The outer wall of the housing 504 is fixedly connected to a motor 501. The output shaft of the motor 501 passes through the housing 504 and is fixedly connected to the center of the second gear 506. The push block includes a hydraulic cylinder 9 and a push plate 10. The hydraulic cylinder 9 is fixedly connected to the end of the housing 504 away from the opening. The output shaft of the hydraulic cylinder 9 passes through the housing 504 and is fixedly connected to the push plate 10 vertically. The push plate 10 is located inside the channel, and the cross-sectional area of ​​the push plate 10 is the same as the cross-sectional area of ​​the channel.

[0020] The specific implementation process is as follows: Blocky nickel-magnesium alloy is poured into the addition box 502 and falls into the channel of the housing 504 through the feed inlet 503. Simultaneously, aluminum granules and calcium silicate powder are added through the feed inlet 503. The hydraulic cylinder 9 is activated, and its output shaft pushes the pusher plate 10 within the channel to push the deoxidizer towards the opening. The cross-sectional area of ​​the pusher plate 10 is the same as that of the channel to ensure no material residue. When the deoxidizer reaches the opening, the motor 501 is activated, driving the second gear 506 to rotate. Through the meshing protrusions 5051, the first gear 505 rotates in the opposite direction. The protrusions 5051 shear against each other, breaking the blocky nickel-magnesium alloy. The broken deoxidizer falls from the opening into the inclined guide groove 4 and slides down the guide groove 4 into the molten pool 1 under gravity. When the robotic arm 3 clamps the electrode blank 2 and descends at a constant speed to melt it, the stabilizing plate 7 and the support rod 6 ensure the stability of the device. Throughout the process, the feed port 503 is located in the center of the channel to ensure that the material is evenly distributed. The addition box 502 facilitates batch feeding and realizes automatic crushing and uniform addition of deoxidizer.
