Description

Technical Field

[0001] The invention relates to the technical field of steelmaking, in particular to a method for reducing the consumption of rolling scrap steel. Background Art

[0002] Rolling is a metal processing technology, which refers to the pressure processing of passing the metal billet through the gap between a pair of rotating rollers, which reduces the cross-section of the material and increases its length due to the compression of the rollers. The rolling process of scrap steel is generally divided into smelting, casting, heating, and rolling before production can be completed;

[0003] However, in the existing rolling process, suitable resources cannot be selected according to needs, and during casting, molten steel splashes out, causing resource consumption. In addition, the waste cannot be filtered and collected, and the waste and molten steel are mixed together, affecting the quality of subsequent steel plates. Therefore, in order to avoid the above-mentioned technical problems, it is necessary to provide a method for reducing the consumption of rolling scrap steel to overcome the above-mentioned defects in the prior art. Summary of the invention

[0004] The present invention provides a method for reducing the consumption of rolling scrap steel, which can effectively solve the problems proposed in the above-mentioned background technology that suitable resources cannot be selected according to needs, and during casting, molten steel splashes out, causing resource consumption. In addition, the waste cannot be filtered and collected, and the waste and molten steel are mixed together, affecting the quality of subsequent steel plates.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for reducing the consumption of rolling scrap steel, comprising the following steps:

[0006] S1, collect the scrap steel, mix and melt it into molten steel, and store it in the ladle tube at the top of the base for later use;

[0007] S2. When molten steel is poured into the ladle tube, the molten steel pushes the movable plate, the vertical rod and the bottom plate downward, pushes the telescopic plate, the storage shell, the vertical frame and the connecting frame downward, forces the movable rod to slide inside the rotating drum, and uses the cooperation of the spiral groove and the spiral convex plate to push the rotating drum and the spiral feeding drum to rotate, and evenly sprinkle the deoxidizer inside the hopper into the ladle tube for mixing;

[0008] S3. At the same time, the scrap steel remaining in the molten steel is filtered out through the filter cylinder inside the top cover, which is convenient for recycling and re-smelting into molten steel;

[0009] S4, pouring the deoxidized molten steel into the support plate and the casting frame, casting the molten steel into a steel plate, and at the same time raising the height of the support plate and the casting frame through the support of the fixed cylinder and the support rod, thereby reducing the splashing of the molten steel when pouring;

[0010] S5. The cast steel plate is transported by a conveyor rack and heated by a heating box to facilitate subsequent rolling. During the heating process, the hot air inside the heating box is sent into the preheating box through a connecting pipe to preheat the steel plate, thereby improving the utilization rate of waste heat from the hot air and reducing energy consumption.

[0011] S6. The steel plate cast from the scrap steel is rolled by upper rollers and lower rollers.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0013] 1. A filtering and feeding mechanism is set up. The waste materials remaining in the molten steel are filtered and stored through the filter cylinder at the bottom of the top cover, which is convenient for the subsequent recycling of waste materials and reduces the consumption of resources. As the molten steel inside the ladle tube increases, the movable plate, the vertical rod and the bottom plate are pushed down, and the telescopic plate is pushed down by the convex block, so that the telescopic plate with the storage shell, the vertical frame and the connecting frame is lowered, and the movable rod is pushed down inside the rotating drum. At the same time, the spiral groove and the spiral convex plate are used to cooperate, so that the movable rod pushes the rotating drum and the spiral feeding drum to rotate when it descends, so that the deoxidizer inside the hopper is evenly sprinkled into the ladle tube according to the molten steel capacity inside the ladle tube, so as to prevent waste caused by excessive addition of deoxidizer;

[0014] The electric push rod pushes the horizontal plate, top cover, filter cylinder and hopper up to release the limit on the ladle. At the same time, the horizontal plate and extension plate cooperate to push the vertical frame, storage shell, extension plate and hopper up to release the limit on the ladle cylinder, making it easy for the ladle cylinder to rotate. The bottom plate, vertical rod and movable plate are pulled to reset through the telescopic characteristics of the supporting spring. At the same time, the rotating motor drives the ladle cylinder to rotate and reset. After the ladle cylinder is reset, the electric push rod is used to reset the top cover, hopper, vertical frame and storage shell. When the connecting plate loses the support of the top plate, the reset spring pushes the pull rod, telescopic plate and connecting plate to reset, making it convenient for the subsequent addition of deoxidizer.

[0015] 2. An anti-splashing and demoulding conveying mechanism is provided. The support plate and the casting frame are supported by the cooperation of the fixed cylinder and the support rod, and the height of the casting frame and the support plate is increased. Therefore, when pouring the molten steel, the drop of the molten steel flowing down is reduced, the splash height of the molten steel is reduced, and the waste of molten steel is reduced. As the ladle cylinder rotates and tilts, the traction plate is driven to rotate, and the cooperation of the support spring and the fixed frame is used to slide the slide plate on the base, and then the support plate and the casting frame are pulled to move by the rotating plate, so that the support plate and the casting frame are lowered, forcing the bottom ends of the L-shaped plates at both ends of the casting frame to engage with the racks at the top of the moving plate, so that the driving motor can pull the moving plate, the rack, the L-shaped plate and the casting frame to slide through the lead screw and the transmission belt, so that the casting frame fits the touch switch at one end of the fixed frame, cuts off the power supply to the driving motor, and starts the cylinder at the same time, so that the cylinder pushes the pressing plate down through the piston rod, and pushes the steel plate inside the casting frame out, thereby improving the convenience of demoulding and facilitating the transportation of the steel plate.

[0016] 3. A rolling adjustment mechanism is provided, and the steel plate removed from the mold is conveyed by the conveying frame. At the same time, during the conveying process, the position of the steel plate is corrected by the anti-deviation plate to prevent the steel plate from being offset, thereby ensuring the conveying effect. After the steel plate is heated by the preheating box and the heating box, it is conveyed between the upper roller and the lower roller for rolling. During the rolling process, the conveying frame drives the lower roller to rotate through the cooperation of the belt, and then the power is transmitted again by the cooperation of the worm gear and the worm, so that the upper roller and the lower roller rotate relative to each other, and the steel plate is squeezed, thereby improving the rolling effect of the steel plate. In addition, the push rod is rotated to move the adjustment plate and the worm, and the meshing between the worm and the worm gear is released. Then, the adjustment rod is rotated to move the slider and the upper roller, thereby changing the distance between the upper roller and the lower roller, and the rolling thickness is adjusted as needed, thereby improving the adaptability. In addition, during the heating process, the heat inside the heating box is sent to the preheating box through the connecting pipe, and the waste heat is utilized to reduce the waste of heat, and the steel plate is preheated in advance, thereby improving the subsequent heating effect of the steel plate and ensuring the rolling effect.

[0017] In summary, the waste remaining in the molten steel is collected through the filtering and feeding mechanism for easy recycling. At the same time, the anti-splashing and demoulding conveying mechanism prevents the molten steel from splashing when pouring, further reducing the waste of resources. Then, the rolling adjustment mechanism cooperates to utilize the waste heat, thereby reducing resource consumption and improving the rolling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The working principle and use process of the present invention are as follows: first, the scrap steel is melted into molten steel and poured into the ladle tube 3. During the pouring process, the scrap steel remaining in the molten steel is filtered through the filter cylinder 504 at the bottom of the top cover 503, so as to facilitate the subsequent recycling of the scrap steel and reduce the waste of resources. As the molten steel inside the ladle tube 3 increases, the pressure increases, and the movable plate 523 is pushed down, so that the movable plate 523 pushes the vertical rod 522 down and the bottom plate 525 down. At the same time, the telescopic plate 520 is pushed through the cooperation of the protrusion, forcing the telescopic plate 520 to carry the storage shell 5 16. The vertical frame 513 and the connecting frame 514 are lowered, so that the connecting frame 514 pushes the movable rod 510 to descend inside the rotating drum 507, and the spiral groove 511 and the spiral convex plate 512 cooperate to make the movable rod 510 push the rotating drum 507 and the spiral feeding drum 509 to rotate during the descending process, and the deoxidizer inside the hopper 505 is evenly sprinkled into the inside of the ladle tube 3 according to the molten steel capacity inside the ladle tube 3, so as to prevent the waste of excessive deoxidizer and save costs. As the deoxidizer is mixed with the molten steel, the oxygen content of the molten steel is reduced, and the subsequent rolling effect is improved;

[0052] Next, after the molten steel and the deoxidizer are mixed, the extension plates 515 at both ends of the horizontal plate 502 are pulled out, and then the electric push rod 501 is started, so that the electric push rod 501 pushes the horizontal plate 502, the top cover 503, the filter cartridge 504 and the hopper 505 to rise. At the same time, during the rising process of the horizontal plate 502, the extension plate 515 pushes the vertical frame 513, the storage shell 516 and the extension plate 515 to rise along the fixed plate 2, and when the vertical frame 513 rises with the storage shell 516 and the extension plate 515, the top plate 519 pushes the connecting plate 518, forcing the connecting plate 518 to move with the pull rod 517 and the telescopic plate 520, thereby facilitating the storage of the telescopic plate 520 inside the storage shell 516, facilitating the sliding of the storage shell 516, and rising together with the vertical frame 513 and the connecting frame 514, facilitating the rotation of the rotating motor 4 with the ladle tube 3 to pour out the molten steel for casting;

[0053] Next, after the molten steel in the steel ladle tube 3 is poured out, the bottom plate 525, the vertical rod 522 and the movable plate 523 are pulled to reset by the telescopic characteristics of the support spring 524, and the steel ladle tube 3 is driven to rotate and reset by the rotating motor 4. After the steel ladle tube 3 is reset, the electric push rod 501 is used to reset the top cover 503, the hopper 505, the vertical frame 513 and the storage shell 516, so that the connecting plate 518 loses the support of the top plate 519, and then the pull rod 517, the telescopic plate 520 and the connecting plate 518 are pushed to reset by the reset spring 521, so as to facilitate the subsequent addition of the deoxidizer;

[0054] Next, the ladle tube 3 tilts to pour the molten steel into the casting frame 604, so that the casting frame 604 cooperates with the support plate 603 to cast the molten steel into a steel plate. At the same time, the ladle tube 3 drives the traction plate 607 to rotate during the pouring of the molten steel, and uses the cooperation of the contraction spring 609 and the fixed frame 608 to make the ladle tube 3 tilt and slide the slide plate 605 on the base 1, and then pull the support plate 603 and the casting frame 604 to move through the rotating plate 606, so that the support plate 603 brings the casting frame 604 and the support rod 602 down along the fixed tube 601, forcing the L-shaped The bottom end of the plate 615 meshes with the rack 616 at the top end of the movable plate 614, so that the motor 617 drives the screw rod 612 to rotate, pulling the movable plate 614, the rack 616, the L-shaped plate 615 and the casting frame 604 to slide. When the casting frame 604 is attached to the touch switch 623 at one end of the fixed frame 611, the power supply to the driving motor 617 is cut off, and the cylinder 620 is started at the same time, so that the cylinder 620 pushes the pressing plate 622 downward through the piston rod 621, and the steel plate inside the casting frame 604 is pushed out, which improves the convenience of demoulding and facilitates the transportation of the steel plate.

[0055] Next, in the process of pouring molten steel, the slide plate 605 is fixed by the positioning pin 610, and the slide plate 605 uses the cooperation of the fixed frame 608, the contraction spring 609 and the traction plate 607 to pull the steel ladle tube 3, thereby ensuring the stability of the steel ladle tube 3. After the casting frame 604 is reset, the positioning pin 610 is rotated out, and the steel ladle tube 3 is rotated and reset by the rotating motor 4. At the same time, the traction plate 607, the contraction spring 609 and the fixed frame 608 are used to slide and reset the slide plate 605, forcing the slide plate 605 to push the supporting plate 603 and the casting frame 604 to reset through the rotating plate 606, thereby increasing the height of the casting frame 604, and then when pouring molten steel, the flow drop is reduced, the splash height of molten steel is reduced, and the waste of molten steel is reduced;

[0056] Finally, the demoulded steel plate falls onto the conveying frame 618, and the steel plate is conveyed by the conveying frame 618. In the process of conveying, the position of the steel plate is corrected by the limit of the anti-deflection plate 715 to prevent the steel plate from deflecting, so that the steel plate enters the preheating box 713 and the heating box 712 correctly, and is heated, and then conveyed to the space between the upper roller 705 and the lower roller 706 for rolling. At the same time, during the rolling process, the conveying frame 618 drives the lower roller 706 to rotate through the cooperation of the belt 711, and the power is transmitted again by the cooperation of the worm gear 707 and the worm 710, so that the upper roller 705 and the lower roller 706 rotate relative to each other. , which improves the rolling effect of the steel plate. In addition, the push rod 708 is rotated to move the adjusting plate 709 and the worm 710 to release the engagement between the worm 710 and the worm wheel 707, and then the adjusting rod 703 is rotated to move the slider 704 and the upper roller 705, thereby changing the distance between the upper roller 705 and the lower roller 706. The rolling thickness is adjusted as needed, thereby improving the adaptability. In addition, during the heating process, the heat inside the heating box 712 is sent to the preheating box 713 through the connecting pipe 714, so that the waste heat is utilized, the heat waste is reduced, the steel plate is preheated in advance, the subsequent heating effect of the steel plate is improved, and the rolling effect is guaranteed.
