A metal continuous casting and rolling integrated processing equipment

Abstract

This utility model discloses an integrated metal continuous casting and rolling processing equipment, specifically relating to the field of metal casting and rolling technology. It includes a base, with an outer shell fixed to one end. A feeding pipe and a crystallizer body are fixed to the top of the base. A first servo motor is fixed to the middle of the top of the outer shell. The power output end of the first servo motor movably passes through a threaded sleeve fixed to the top of the outer shell. A fixed seat is fixed to the bottom of the inner wall of the outer shell via a support rod. This device feeds the billet into the top of the fixed seat, first extruding it through rollers with a larger spacing, then through rollers with a medium spacing, and finally through rollers with a smaller spacing, ultimately forming the molten metal.

Description

Technical Field

[0001] This utility model relates to the field of metal casting and rolling technology, specifically to an integrated processing equipment for continuous metal casting and rolling. Background Technology

[0002] Casting and rolling is a short-process near-net-shape forming process that combines metal smelting and rolling. It involves directly injecting molten metal into the gap between rotating rolls, achieving rapid solidification while simultaneously undergoing rolling deformation to directly produce sheet or strip billets. Its core principle utilizes the cooling and rolling action of a twin-roll mill to allow the molten metal to solidify, form, and undergo preliminary plastic processing within the roll gap, combining the forming capabilities of casting with the microstructure optimization effects of rolling.

[0003] Compared to the traditional two-step casting and rolling process, the advantages of the casting and rolling process are: reduced costs, eliminating the aluminum ingot remelting step, reducing the processing cost per ton by 700-800 yuan, and reducing metal loss from 5% to below 1%; improved performance, with rapid solidification increasing the tensile strength of aluminum alloy cast and rolled plates by 15%-20% and the elongation by 8%-12%; and environmental benefits, reducing emissions from heating furnaces, and reducing carbon emissions per unit product by about 30%.

[0004] The aforementioned device typically uses two rollers to directly extrude the molten metal during the extrusion deformation process, forming the metal in one step. The metal deformation is large, and the extrusion force required is also large. The rollers and roller support components need to provide a large support force. Long-term use can easily lead to the roller position shifting. Furthermore, existing integrated metal casting and rolling equipment produces metal plates with uniform thickness, making it inconvenient to adjust the roller position for different plate thicknesses. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an integrated metal continuous casting and rolling processing equipment, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an integrated metal continuous casting and rolling processing equipment, including a base, an outer shell fixed to one end of the base, a material conveying pipe and a crystallizer body fixed to the top of the base, a first servo motor fixed to the middle of the top of the outer shell, a threaded sleeve rod fixed to the power output end of the first servo motor through the top of the outer shell, a fixed seat fixed to the bottom of the inner wall of the outer shell by a support rod, a movable seat movably installed to the top of the inner wall of the outer shell, a roll body fixed to the opposite side of the movable seat and the fixed seat, a first threaded rod fixed to the middle of the top of the movable seat, and the first threaded rod being threadedly connected to the threaded sleeve rod.

[0007] Furthermore, the movable seat and the fixed seat are arranged symmetrically, the movable seat and the fixed seat are arranged at an angle near one end of the conveying pipe, and the movable seat and the fixed seat are arranged parallel to each other at the other end.

[0008] Furthermore, the roll body is provided in two sets, and the two sets of roll bodies are respectively located on the inner wall of the moving seat and the fixed seat and are arranged horizontally at equal intervals.

[0009] Furthermore, sliding grooves are provided on both sides of the outer wall of the outer shell, and sliders are fixed at both ends of both sides of the movable seat. The four sliders are slidably connected to the four sliding grooves respectively.

[0010] Furthermore, each of the two sliders located on the same side of the outer shell has a connecting rod fixed at one end, and the outer walls of the two sliders located on the same side are movably fitted with extrusion plates. A second servo motor is fixed in the middle of one of the connecting rods, and a support block is fixed in the middle of the other connecting rod.

[0011] Furthermore, the power output end of the second servo motor is fixed with a second threaded rod, the other end of the second threaded rod is rotatably connected to the support block, the threads on both sides of the middle of the second threaded rod are opposite in direction, and the two ends of the outer wall of the second threaded rod are respectively threadedly connected to the two extrusion plates. The middle of both sides of the outer wall of the outer shell is provided with a placement groove, and the second threaded rod passes through the placement groove.

[0012] Furthermore, a feed pipe is fixedly installed through the top of the crystallizer body, and the bottom of one end of the feed pipe and the top of one end of the fixed base are located on the same horizontal plane.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application involves feeding the billet into the top of the fixed seat, first extruding it through rollers with a larger spacing, then through rollers with a medium spacing, and finally through rollers with a smaller spacing, thus extruding and forming the molten metal in multiple layers. This reduces the force on each roller and achieves multi-layer progressive extrusion of the metal, reducing the force required for a single extrusion and lowering the risk of damage to the rollers due to prolonged high-intensity use.

[0014] 2. This application controls the first servo motor to adjust the distance between the two rollers with the smallest spacing, and controls the second servo motor to drive the second threaded rod to rotate. The second threaded rod with different thread directions at both ends causes the two extrusion plates to move towards the center at the same time. The two extrusion plates are in contact with the outer wall of the outer shell. The extrusion plates squeeze the outer shell to generate friction, which further supports the moving seat. This achieves the effect of quickly adjusting the position of the rollers to better adapt to the use of finished metal sheets of different thicknesses. At the same time, it further supports the rollers to prevent the position of the rollers from shifting during use. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0020] This application discloses an integrated metal continuous casting and rolling processing equipment, including a base 1, an outer shell 2 fixed to one end of the base 1, a material conveying pipe 3 and a crystallizer body 4 fixed to the top of the base 1, a first servo motor 5 fixed to the middle of the top of the outer shell 2, the power output end of the first servo motor 5 movably passing through the top of the outer shell 2 and a threaded sleeve rod 6 fixed thereon, a fixed seat 9 fixed to the bottom of the inner wall of the outer shell 2 by a support rod 12, a movable seat 8 movably installed on the top of the inner wall of the outer shell 2, a roll body 10 fixed to the opposite side of the movable seat 8 and the fixed seat 9, a first threaded rod 7 fixed to the middle of the top of the movable seat 8, and the first threaded rod 7 being threadedly connected to the threaded sleeve rod 6.

[0021] Reference Appendix Figure 5 The movable seat 8 and the fixed seat 9 are arranged symmetrically. The movable seat 8 and the fixed seat 9 are inclined at one end near the conveying pipe 3, and parallel at the other end. There are two sets of roller bodies 10. The two sets of roller bodies 10 are located on the inner walls of the movable seat 8 and the fixed seat 9 respectively and are arranged horizontally at equal intervals. This allows the molten metal entering the outer shell 2 to be squeezed first by the roller bodies 10 with larger spacing, then by the roller bodies 10 with medium spacing, and finally by the roller bodies 10 with smaller spacing, and finally squeezed into shape. The molten metal is squeezed in multiple layers, which reduces the force on the roller body 10 corresponding to each squeeze.

[0022] Reference Appendix Figure 3 The outer wall of the outer shell 2 has sliding grooves 13 through both sides. The two ends of the moving seat 8 are fixed with sliders 11. The four sliders 11 are slidably connected to the four sliding grooves 13 respectively. The first servo motor 5 drives the threaded sleeve 6 to rotate, which in turn drives the threaded rod 7 to rise and fall. The sliders 11 and the sliding grooves 13 cooperate to allow the moving seat 8 to move up and down inside the top of the outer shell 2, thereby adjusting the distance between the moving seat 8 and the fixed seat 9, adjusting the distance between the two roller bodies 10 with the smallest distance, and controlling the thickness of the extruded metal plate.

[0023] Reference Appendix Figure 2 and 4Two sliders 11 located on the same side of the outer shell 2 are each fixed with a connecting rod 15 at one end, and extrusion plates 18 are movably sleeved on the outer walls of the two sliders 11 located on the same side. A second servo motor 16 is fixed in the middle of one connecting rod 15, and a support block 19 is fixed in the middle of the other connecting rod 15. A second threaded rod 17 is fixed to the power output end of the second servo motor 16, and the other end of the second threaded rod 17 is rotatably connected to the support block 19. The threads on both sides of the middle of the second threaded rod 17 are in opposite directions, and the two ends of the outer wall of the second threaded rod 17 are respectively threaded through to the two extrusion plates 18. The middle of both sides of the outer wall of the outer shell 2 are... A placement slot 14 is provided, and a second threaded rod 17 passes through the placement slot 14. The second threaded rod 17 is driven to rotate by a second servo motor 16. A support block 19 supports one end of the second threaded rod 17 to prevent it from shaking when rotating due to its excessive length. The two threaded rods 17 with different thread directions at both ends cause the two extrusion plates 18 to move towards the center at the same time. The two extrusion plates 18 are in contact with the outer wall of the outer shell 2. The extrusion plates 18 extrude friction by pressing the outer shell 2, which further supports the moving seat 8. When it is necessary to adjust the height of the moving seat 8, the second servo motor 16 is controlled to rotate in the opposite direction to release the limit of the extrusion plates 18.

[0024] Reference Appendix Figure 1 The top of the crystallizer body 4 is fixed with a feed pipe 20. The bottom of one end of the feed pipe 3 and the top of one end of the fixed seat 9 are at the same level. Molten metal is added from the feed pipe 20 and melted through the crystallizer body 4 to form an initial billet. The billet is then transported to the inside of the outer shell 2 through the feed pipe 3 and enters the top of the fixed seat 9.

[0025] The workflow of this utility model is as follows: First, adjust the horizontal position of the moving seat 8 according to the required thickness of the metal sheet. The first servo motor 5 drives the threaded sleeve 6 to rotate, which in turn drives the threaded rod 7 to rise and fall. The slider 11 and the slide groove 13 cooperate, allowing the moving seat 8 to move up and down inside the top of the outer shell 2, thereby adjusting the distance between the moving seat 8 and the fixed seat 9. Adjusting the distance between the two rollers 10 with the smallest distance controls the thickness of the extruded metal sheet. After the position of the moving seat 8 is adjusted, the second servo motor 16 drives the second threaded rod 17 to rotate. The support block 19 supports one end of the second threaded rod 17 to prevent it from vibrating during rotation due to its excessive length. The second threaded rod has different thread directions at both ends. The rib 17 causes the two extrusion plates 18 to move towards the center simultaneously. The two extrusion plates 18 are in contact with the outer wall of the outer shell 2. The extrusion plates 18 extrude the outer shell 2 to generate friction, which further supports the moving seat 8. Molten metal is then added from the feed pipe 20 and melted through the crystallizer body 4 to form an initial billet. The billet is then transported to the inside of the outer shell 2 through the conveying pipe 3. The billet enters the top of the fixed seat 9 and is first extruded by the rollers 10 with a larger spacing, then by the rollers 10 with a medium spacing, and finally by the rollers 10 with a smaller spacing. Finally, the billet is extruded and formed. The molten metal is extruded in multiple layers to reduce the force on the rollers 10 corresponding to each extrusion.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
