Description

Technical Field

[0001] This utility model relates to the field of electroslag ingot processing technology, and in particular to an electroslag ingot temporary storage cover. Background Technology

[0002] Electroslag ingots are refined through a secondary remelting process using resistance heating of molten slag, and are often formed into columnar structures. However, the forming efficiency of electroslag ingots is relatively low, and the interval between forming adjacent ingots is long. To improve the mechanical strength of the ingots, they need to be heat-treated after being removed from the furnace. To increase the amount of ingots processed at one time, a certain number of ingots must be accumulated before heat treatment. During this waiting period, the ingots cool too quickly in the air, resulting in cracks or other defects. One way to avoid this problem is to bury the formed ingots in sand and gravel to slow down the cooling rate. However, this method requires digging an insulated pit in the insulated sand pile before placing the ingots, a cumbersome process. Furthermore, the ingots need to be excavated later, and there are difficulties in measuring their temperature, all of which bring many inconveniences to the implementation of the heat treatment process. Utility Model Content

[0003] This utility model provides a temporary storage cover for electroslag ingots to overcome the shortcomings of the prior art and solve the problem of inconvenient heat preservation of electroslag ingots, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] An electroslag ingot temporary storage cover includes a chassis, an insulation cover on the chassis, a top cover fixed to the upper end of the insulation cover, and an inner cover on the lower wall of the top cover. The electroslag ingot is placed on the chassis, and the inner cover, made of ceramic material, covers the electroslag ingot to block heat dissipation. The chassis supports the electroslag ingot to prevent it from dissipating heat downwards. A refractory felt or a pad made of inorganic ceramic material such as sand and gravel is laid on the chassis, and the electroslag ingot is placed on the refractory felt to prevent downward diffusion, thereby reducing the cooling rate of the electroslag ingot. The enclosed space formed by the insulation cover and the top cover provides thermal insulation protection for the electroslag ingot, further reducing its cooling rate.

[0006] Furthermore, the lower wall of the chassis is bolted with a support base to decouple the base from the ground, thereby preventing heat conduction from the chassis to the ground.

[0007] Furthermore, the insulation cover includes an outer shell, inside which is an inner shell. There is an annular gap between the inner shell and the outer shell, and multiple inner support strips are provided in the annular gap. The inner support strips are made of molybdenum alloy, and the annular gap is filled with fire-resistant felt. The inner support strips not only strengthen and fix the outer shell and the inner shell, but also, due to the use of molybdenum alloy, which has a strong ability to emit heat radiation, thus improving the insulation effect. The fire-resistant felt further reduces the rate of heat diffusion.

[0008] Furthermore, a pair of concave handles are welded onto the outer shell to facilitate the opening or installation of the insulation cover.

[0009] Furthermore, the inner support bar includes an arc-shaped plate that abuts against the outer wall of the inner shell. A circular arc plate is formed on the arc-shaped plate. The outer periphery of the circular arc plate is tangent to the inner wall of the outer shell. Both the arc-shaped plate and the circular arc plate have an inwardly curved structure. A support plate is provided in the internal space of the arc-shaped plate and the circular arc plate. The arc-shaped structure of the arc-shaped plate and the circular arc plate helps to reflect heat. The support plate not only strengthens the structural strength of the inner support bar, but also helps to reflect heat.

[0010] Furthermore, a window is provided on the top cover, and a stopper is inserted into the window to facilitate the operator's monitoring of the temperature of the electroslag ingot.

[0011] Furthermore, a pair of lower extension rings are welded to the lower wall of the top cover. The inner lower extension ring is welded to the inner shell, and the outer lower extension ring is welded to the outer shell. The lower extension rings are designed to enhance the fixation of the top cover.

[0012] Furthermore, to secure the insulation cover to the chassis, a pair of symmetrical upper arc plates are bolted onto the chassis. Each upper arc plate has a pair of rectangular holes, through which concave insert plates pass. These concave insert plates are positioned at the lower end of the insulation cover. An outer extension guide rod passes through the outer end of each concave insert plate. An inner seat is welded to the inner end of each extension guide rod, and the inner side of the inner seat is welded to the outer side of the insulation cover. An outer plate is welded to the outer end of each extension guide rod, and a protrusion is formed on the outer plate. The convex head is equipped with a rotating shaft. The two ends of the rotating shaft are limited axially by cotter pins or nuts. An inner top recess is rotatably provided on the rotating shaft. The inner end of the inner top recess abuts against the outer wall of the concave insert plate, and the length direction of the inner top recess is parallel to the length direction of the concave insert plate, so that the concave insert plate passes through the lower end of the heat insulation cover and the rectangular hole. A spring is sleeved on the outer extension guide rod. The inner end of the spring abuts against the inner seat, and the outer end of the spring abuts against the inner wall of the concave insert plate.

[0013] The advantages of the above technical solution are:

[0014] This invention slows down the cooling rate of electroslag ingots by using external protection and detachment from ground contact, and facilitates temperature monitoring during the protective placement process. It also offers the advantage of ease of operation compared to burying them in insulating sand. Attached Figure Description

[0021] Figure 6 A magnified view of point B is shown. Detailed Implementation

[0022] like Figures 1-6 As shown, a temporary storage cover for electroslag ingots includes a chassis 1. A support base 10 is bolted to the lower wall of the chassis 1. An insulation cover is provided on the chassis 1. An upper cover 4 is fixed to the upper end of the insulation cover. A window is opened on the upper cover 4. A plug 42 is inserted into the window. An inner cover 41 is provided on the lower wall of the upper cover 4. Electroslag ingots are placed on the chassis 1, and the inner cover 41 covers the electroslag ingots.

[0023] The insulation cover includes an outer shell 3, on which a pair of concave handles 30 are welded. Inside the outer shell 3, there is an inner shell 31. There is an annular gap between the inner shell 31 and the outer shell 3. Multiple inner support strips are provided in the annular gap. The inner support strips are made of molybdenum alloy, and the annular gap is filled with fire-resistant felt. The inner support strips include an arc-shaped plate 33 that abuts against the outer wall of the inner shell 31. An arc-shaped plate 32 is formed on the arc-shaped plate 33. The outer periphery of the arc-shaped plate 32 is tangent to the inner wall of the outer shell 3. Both the arc-shaped plate 33 and the arc-shaped plate 32 have an inwardly curved structure. A support plate 34 is provided in the internal space of the arc-shaped plate 33 and the arc-shaped plate 32.

[0024] In this embodiment, the operator first lays refractory felt on the chassis 1, and then transfers the prepared electroslag ingot onto the refractory felt on the chassis 1.

[0025] Then, the hook on the crane is attached to the concave handle 30, and the insulation cover is moved to the top of the electroslag ingot by the crane, so that the electroslag ingot is facing the inner cover 41. Then, the insulation cover is placed downward and covered on the electroslag ingot. Then, the operator can measure and monitor the temperature of the electroslag ingot in real time through the window.

[0026] During the protection process, the heat emitted from the electroslag ingot first passes through the inner cover 41. Since the inner cover 41 is made of inorganic material, it has a heat-insulating effect, thus reducing the heat radiation efficiency. When the heat passes through the inner shell 31 and the outer shell 3, it will be reflected by the inner support strips inside, and the part that passes through will also be insulated by the refractory felt. This will significantly reduce the heat dissipation rate of the electroslag ingot.

[0027] In some embodiments, a pair of lower extension rings 40 are welded to the lower wall of the upper cover 4. The lower extension ring 40 located on the inner side is welded to the inner shell 31, and the lower extension ring 40 located on the outer side is welded to the outer shell 3. In this way, the security of the fixed connection of the upper cover 4 can be improved.

[0028] In some embodiments, a pair of symmetrical upper arc plates 11 are bolted to the chassis 1. The upper arc plates 11 are located outside the inner shell 31 and outside the inner cover 41. A pair of rectangular holes 12 are provided on the upper arc plates 11. A concave insert plate 26 passes through the rectangular holes 12. The concave insert plate 26 passes through the lower end of the heat insulation cover. An outer extension guide rod 20 passes through the outer end of the concave insert plate 26. An inner seat 2 is welded to the inner end of the outer extension guide rod 20. The inner side of the inner seat 2 is welded to the outer side of the heat insulation cover. An outer plate 21 is welded to the outer end of the outer extension guide rod 20. The outer plate 21 is formed with... A convex head 22 is rotatably mounted on a rotating shaft 23. The two ends of the rotating shaft are axially limited by cotter pins or nuts. An inner top recess 24 is rotatably mounted on the rotating shaft 23. The inner end of the inner top recess 24 abuts against the outer wall of the concave insert 26, and the length direction of the inner top recess 24 is parallel to the length direction of the concave insert 26, so that the concave insert 26 passes through the lower end of the heat insulation cover and the rectangular hole 12. A spring 25 is sleeved on the outer extension guide rod 20. The inner end of the spring 25 abuts against the inner seat 2, and the outer end of the spring 25 abuts against the inner wall of the concave insert 26.

[0029] In this embodiment, when the heat insulation cover is in place and the concave insert plate 26 is aligned with the rectangular hole 12, the operator rotates the inner top recess 24. When the inner top recess 24 rotates, its arc segment will push the concave insert plate 26 inward. During this process, the spring 25 is also compressed. At the same time, the concave insert plate 26 will be inserted into the rectangular hole 12, thus fixing the heat insulation cover suspended on the chassis 1.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
