Description

Technical Field

[0001] This utility model relates to the field of electroslag ingot processing technology, and in particular to an electroslag ingot outer layer slag removal device. Background Technology

[0002] After electroslag ingots are melted and cast, an oxide layer forms on their outer surface. This oxide layer is brittle and has high hardness, and direct processing may result in a rough surface or cracks. Currently, the cleaning process uses a grinding machine lifted by a crane. This method is prone to accidents due to flying oxide layers during grinding. Furthermore, the electroslag ingot must be cooled to a certain temperature before grinding can begin. As the temperature decreases, the contact force between the oxide layer and the electroslag ingot increases, thus increasing the difficulty of grinding. Utility Model Content

[0003] This utility model provides a slag removal device for the outer layer of electroslag ingots, which solves the shortcomings of the prior art and addresses the problem of the difficulty in polishing the outer skin of the oxide layer of electroslag ingots, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: An electroslag ingot outer layer slag removal device includes a chassis with multiple rectangular columns welded to its lower end. A base plate is welded to the lower end of each rectangular column. The electroslag ingot is coaxially placed on the chassis. A circular cover is fitted onto the chassis, and a rotating mechanism is mounted on the circular cover. Multiple scraping mechanisms are mounted on the rotating mechanism. The chassis and rectangular columns serve as support components during the electroslag ingot melting and casting process. The circular cover provides protection during the treatment of the oxide layer, preventing the scraped oxide layer from splashing out and causing safety accidents. The rotating mechanism drives the scraping mechanisms to rotate, thereby automatically scraping away the oxide layer on the outer layer of the electroslag ingot. The scraping operation is performed when the electroslag ingot temperature is relatively high in the early stages to quickly remove the oxide layer.

[0005] Furthermore, in order to enable the circular cover to be coaxial with the electroslag ingot for facilitating the scraping of the ingot's outer skin, a rotating ring is provided at the lower end of the circular cover. Limiting rings are provided on the upper and lower sides of the rotating ring, and these rings are fixed to the circular cover by pins. An oblique hole is provided on the rotating ring, with its length direction forming an angle with the radial direction of the rotating ring. A movable rod passes through the oblique hole, and a limiting nut is threaded to the lower end of the movable rod. The limiting nut is located on the lower side of the rotating ring. A movable block is welded to the upper end of the movable rod, and a through rod is provided on the movable block. The through rod passes through the lower end of the circular cover, with its length direction parallel to the radial direction of the rotating ring. A concave sleeve is welded to the inner end of the through rod, and this concave sleeve is fitted onto a rectangular column. This method allows the concave sleeve to move inward synchronously, thereby connecting the concave sleeve and the rectangular column, facilitating the connection between the circular cover and the chassis.

[0006] Furthermore, the rotating mechanism includes a pair of rotating seats bolted to a circular cover. The circular cover has a notch. A motor is bolted to the upper rotating seat. The output shaft of the motor is connected to a gear. The gear is rotatably mounted on the rotating seat via the shaft. A gear ring is rotatably mounted inside the circular cover. The gear meshes with the gear ring. Both the upper and lower sides of the gear ring have annular grooves. Inserted rings are provided on the upper and lower sides of the gear ring. The longitudinal section of the inserted ring is T-shaped. The lower side of the inserted ring passes through the annular groove. The inserted ring is fixed to the inner circumference of the circular cover by screws. The inserted rings play a limiting and constraining role in the rotation of the gear ring. The transmission system formed by the gear ring and the gear enables the scraping mechanism mounted on the gear ring to rotate.

[0007] Furthermore, the scraping mechanism includes a T-shaped seat installed on the inner wall of the toothed ring by screws. A concave vertical member is installed on the inner end of the T-shaped seat by bolts. Multiple transverse holes are opened on the concave vertical member. A moving rod is inserted through the transverse holes. A scraper is provided on the moving rod. The two ends of the moving rod are connected to end nuts by threads. The end nuts are located on the outside of the concave vertical member. During the scraping operation, the blade of the scraper abuts against the outer skin of the electroslag ingot and can scrape off the oxide layer on the outer skin when rotating. In order to adjust the position of the scraper, a moving rod is inserted through the scraper and inserted through the transverse holes.

[0008] Furthermore, an inner shaft is inserted through the outer side of the upper end of the concave vertical member. The two ends of the inner shaft are respectively connected to connecting nuts by threads. The connecting nuts are located on the outer side of the concave vertical member. A rotating sleeve is rotatably mounted on the inner shaft. The outer circumference of the rotating sleeve is tangent to the wedge block. The inner wall of the wedge block abuts against the outer wall of the scraper. The outer wall of the wedge block is a slope, and the lower end of the slope extends inward. When the wedge block moves downward, its inner wall will push the scraper inward under the drive of the rotating sleeve, thereby causing the blade of the scraper to abut against the outer skin of the electroslag ingot, thus facilitating the scraping operation of the outer skin of the electroslag ingot.

[0009] Furthermore, a concave arm is welded to the upper end of the concave vertical member. A vertical hole is opened on the vertical section of the concave arm, and a limiting screw is inserted into the vertical hole. The inner end of the limiting screw is connected to the upper end of the wedge block by a thread. A horizontally arranged strip hole is opened at the upper end of the wedge block, and a pressure rod is inserted into the strip hole. A concave top member is provided on the pressure rod. The concave top member is rotatably mounted on the upper end of the concave arm through a central shaft. When the concave top member is rotated, it can push the wedge block downward through the pressure rod, thereby achieving the purpose of adjusting the position of the scraper.

[0010] The advantages of the above technical solution are: This invention, when scraping off the outer skin of electroslag ingots, can prevent the outer skin from splashing out and causing safety accidents by using a circular cover, and can also improve the effect and efficiency of skin removal.

A movable block 33 is welded to the upper end of the movable rod 31. A through rod 34 is provided on the movable block 33. The through rod 34 is inserted into the lower end of the circular cover 4. The length direction of the through rod 34 is parallel to the radial direction of the rotating ring 3. A concave sleeve 35 is welded to the inner end of the through rod 34. The concave sleeve 35 is fitted onto the rectangular column 10.

[0021] The rotating mechanism includes a pair of rotating seats 40 bolted to a circular cover 4. The circular cover 4 has a notch. A motor 41 is bolted to the upper rotating seat 40. The output shaft of the motor 41 is connected to a gear 42. The gear 42 is rotatably mounted on the rotating seat 40 via a shaft. A gear ring 43 is rotatably mounted inside the circular cover 4. The gear 42 meshes with the gear ring 43. Both the upper and lower sides of the gear ring 43 have annular grooves. The upper and lower sides of the gear ring 43 are respectively provided with insert rings 44. The longitudinal section of the insert ring 44 is T-shaped. The lower side of the insert ring 44 passes through the annular groove. The insert ring 44 is fixed to the inner circumference of the circular cover 4 by screws.

[0022] The scraping mechanism includes a T-shaped seat 5 mounted to the inner wall of a toothed ring 43 by screws. A concave vertical member 50 is bolted to the inner end of the T-shaped seat 5. The concave vertical member 50 has multiple transverse holes 51. A moving rod 52 passes through the transverse holes 51. A scraper 53 is mounted on the moving rod 52. End nuts are threaded to both ends of the moving rod 52 and are located on the outer side of the concave vertical member 50. An inner shaft 54 ​​passes through the outer side of the upper end of the concave vertical member 50. Connecting nuts are threaded to both ends of the inner shaft 54 ​​and are located on the outer side of the concave vertical member 50. A rotating sleeve 63 is rotatably mounted on the inner shaft 54. The outer circumference of the rotating sleeve 63 is tangent to a wedge block 55. The inner wall of the wedge block 55 abuts against the outer wall of the scraper 53. The outer wall of the wedge block 55 is a slope, and the lower end of the slope extends inward. A concave arm 60 is welded to the upper end of the concave vertical member 50.

[0023] In this embodiment, the operator uses a crane to place the circular cover 4 onto the electroslag ingot 2, while its lower end is placed on the ground.

[0024] The operator then rotates the rotating ring 3. As the ring rotates, it acts on the movable rod 31 through the oblique hole 30, causing the rod 31 to move inward. During this movement, the concave sleeve 35 is fitted onto the rectangular column 10. After rotation, the screw on the limiting ring can be rotated to ensure its inner end rests against the rotating ring 3, thus preventing the ring 3 from rotating during the scraping process.

[0025] Next, the operator uses a long-handled tool such as a pry bar to rotate the concave top part 58. When the concave top part 58 rotates, the pressure rod 57 at its lower end will act on the strip hole 56, thereby causing the wedge block 55 to move downward. During the downward movement, the action of its inclined surface and the rotating sleeve 63 will cause it to move inward, thereby causing the scraper 53 to move inward, and thus causing the blade of the scraper 53 to abut against the outer wall of the electroslag ingot.

[0026] Finally, the operator starts the motor 41. Driven by the motor 41, the gear 42 rotates. The rotation of the gear 42 will drive the gear ring 43 to rotate, and the rotation of the gear ring 43 will drive the scraper 53 to rotate. As the scraper 53 rotates, the oxide scale on the outer skin of the electroslag ingot can be scraped off.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
