Description

Technical Field

[0001] The utility model belongs to the technical field of slag removal devices, in particular to a slag removal device for a continuous casting and rolling production line. Background Art

[0002] At present, copper rods are almost all produced and processed by continuous casting and rolling equipment. Various copper raw materials are heated and melted, and then cast and cooled to form, and then stretched and extruded.

The output end of the motor 19 passes through the workbench 1 and is fixedly connected to the bottom surface of the vertical cylinder 2. By turning on the motor 19 and allowing the motor 19 to drive the vertical cylinder 2 to rotate, the vertical cylinder 2 can drive the lifting cylinder 3 to move longitudinally through the threads.

[0028] A vertical rod 17 is fixedly provided longitudinally on the top surface of the workbench 1 and on one side of the vertical cylinder 2. A limit plate 18 is fixedly provided on the upper half of the peripheral side of the lifting cylinder 3. One end of the limit plate 18 is slidably sleeved on the peripheral side of the vertical rod 17, so that the vertical rod 17 and the limit plate 18 can limit the lifting cylinder 3 and assist the lifting cylinder 3 in longitudinal movement.

[0029] A hydraulic cylinder 4 is fixedly provided on the top surface of the lifting cylinder 3 through an L-shaped support block, and a piston rod of the hydraulic cylinder 4 is fixedly connected to a movable plate 5, and the bottom surface of the movable plate 5 is in frictional contact with the top surface of the support block. A slag scraper 7 for handling slag is provided on the bottom surface of the movable plate 5 and on one side of the support block through a rectangular block 6. The hydraulic cylinder 4 can drive the movable plate 5 to move laterally, so that the movable plate 5 can drive the slag scraper 7 to move back and forth laterally through the rectangular block 6, and the vertical cylinder 2 and the lifting cylinder 3 will drive the movable plate 5 to move longitudinally, that is, drive the slag scraper 7 to reciprocate longitudinally, thereby satisfying the longitudinal and transverse reciprocating motion of the slag scraper 7, and the slag scraper 7 can be moved to the inside of the ladle to scrape the slag.

[0030] A vertical plate 8 is fixedly arranged on the top surface of the workbench 1 in the longitudinal direction. The vertical plate 8 is arranged between the vertical cylinder 2 and the slag bucket 7. Two scraper rubber strips 9 are arranged on the side of the vertical plate 8 facing the slag bucket 7. The width of the scraper rubber strips 9 is the same as the width of the inner cavity of the slag bucket 7. A plurality of springs 10 are equidistantly connected between the vertical plate 8 and the two scraper rubber strips 9. Limit rods 11 are fixedly arranged on one side of the two scraper rubber strips 9 and on both sides of the plurality of springs 10. One end of each limit rod 11 penetrates one side of the vertical plate 8. After the slag bucket 7 has scraped the slag, the slag bucket 7 is moved to one side of the scraper rubber strips 9 by the vertical cylinder 2, the lifting cylinder 3 and the hydraulic cylinder 4, and the slag bucket 7 continues to move laterally so that the scraper rubber strips 9 can enter the inner cavity of the slag bucket 7 and press against the slag bucket 7. The scraper strip 9 will squeeze the spring 10 at the same time, so that the scraper strip 9 can be pressed against the inner wall of the slag bucket 7 through the rebound force of the spring 10. At this time, the slag bucket 7 is allowed to move longitudinally through the vertical cylinder 2 and the lifting cylinder 3, so that the slag bucket 7 can move with the scraper strip 9 against the inner wall of the slag bucket 7, so that the scraper strip 9 can clean the slag attached to the inner wall of the slag bucket 7. After cleaning, the slag bucket 7 can continue to be moved into the ladle to scrape the slag, so as to avoid the attached slag from re-entering the ladle, thereby improving the efficiency and effect of slag removal. The setting of the spring 10 can make the scraper strip 9 move along the inclined surface of the slag bucket 7, ensuring that the scraper strip 9 always fits the inner wall of the slag bucket 7.

[0031] The two sides of the rectangular block 6 are rotatably connected with a rotating rod 14, and the circumferential sides of the two rotating rods 14 are fixedly sleeved with a fixed block 15.

The top surface of the movable plate 5 and above the slag bucket 7 are fixedly provided with a cylinder 12, and the piston rod of the cylinder 12 is symmetrically fixed with a rack 13 through a cross plate. The two racks 13 are respectively arranged on both sides of the movable plate 5, and the opposite ends of the two rotating rods 14 are fixed with a gear 16 meshing with the rack 13. The two gears 16 They are respectively arranged on one side of the two racks 13. By turning on the cylinder 12, the cylinder 12 drives the rack 13 to move longitudinally through the cross plate, so that the rack 13 can drive the meshing gear 16 to rotate, and the rotation of the gear 16 will drive the rotating rod 14 to rotate, so that the rotating rod 14 will drive the slag bucket 7 to rotate through the fixed block 15, so that the slag bucket 7 can be convenient for slag removal, and the slag bucket 7 can be placed in a longitudinal vertical state, so that the scraper strip 9 can be convenient for cleaning the attached slag. A collecting bucket for collecting slag is arranged on one side of the vertical plate 8 and below the slag bucket 7. The scraper strip 9 is arranged above the collecting bucket, and the cleaned slag can be collected and processed.

[0032] Working principle:

[0033] The slag removal device of the continuous casting and rolling production line moves the slag removal device to the working area, and drives the vertical cylinder 2 to rotate through the motor 19, which can drive the lifting cylinder 3 to move upward, so that the lifting cylinder 3 drives the slag removal bucket 7 to move above the molten steel ladle, and starts the hydraulic cylinder 4, which can drive the slag removal bucket 7 to move just above the molten steel ladle. At this time, the vertical cylinder 2 is rotated in the opposite direction, which can drive the lifting cylinder 3 to move downward, so that the slag removal bucket 7 enters the inside of the molten steel ladle, and cooperates with the hydraulic cylinder 4 to drive the slag removal bucket 7 to reciprocate to remove the slag. When the slag removal is completed, the vertical cylinder 2, the lifting cylinder 3 and the hydraulic cylinder are used to move the slag removal bucket 7 to the upper side of the molten steel ladle. The scraper bucket 7 is moved to one side of the scraper rubber strip 9, and the scraper bucket 7 is continued to move horizontally, so that the scraper rubber strip 9 can enter the interior of the scraper bucket 7 and press against one side of the scraper bucket 7. At this time, the scraper bucket 7 is driven to move longitudinally by the vertical cylinder 2 and the lifting cylinder 3, so that the scraper rubber strip 9 can press against the inner wall of the scraper bucket 7 to move, so that the scraper rubber strip 9 can clean the slag attached to the inner wall of the scraper bucket 7. After cleaning, the scraper bucket 7 can be moved into the ladle to scrape the slag, so as to prevent the attached slag from re-entering the ladle, thereby improving the efficiency and effect of slag removal.
