[0019] The following description, with reference to the accompanying drawings, describes a device for reducing the shaking amplitude of a refining furnace cover during lifting and lowering.

[0020] As shown in Figure 1- Figure 5 As shown in the figure, a device for reducing the shaking amplitude of the refining furnace cover according to an embodiment of the present invention is applied to a refining furnace 1 and includes: a limiting mechanism 2.

[0021] The limiting mechanism 2 includes a mounting box 21, a limiting post 24, a cylinder 26, a connecting hole 27, a mounting base 28, and a fixing component 29.

[0022] The mounting boxes 21 are respectively set on both sides of the refining furnace 1. The outer wall of the mounting box 21 is provided with mounting grooves 22. The cylinders 26 are respectively set in the corresponding mounting grooves 22. The inner wall of the mounting grooves 22 is provided with connecting holes 27. The output shaft of the cylinder 26 passes through the connecting hole 27 and is connected to the mounting base 28. The fixing component 29 is set on the mounting base 28.

[0024] The fixing assembly 29 includes a push cylinder 291, a fixing plate 292, and a fixing shell 295.

[0025] Among them, push cylinders 291 are respectively mounted on mounting base 28, fixing plate 292 is mounted on the outer wall of mounting base 28, fixing shell 295 is connected to the output shaft of push cylinder 291, and the inner wall of fixing shell 295 is provided with slot 296.

[0026] The outer wall of the fixing plate 292 is provided with a slide rail 293, and the outer wall of the mounting box 21 is provided with a slide groove 294.

[0027] The outer wall of the push cylinder 291 is fitted with a fixing frame 297, and the inner wall size of the fixing frame 297 matches the outer wall size of the push cylinder 291.

[0028] Specifically, when refining furnace 1 completes the secondary refining of the molten steel, pusher cylinder 291 is activated to circulate the gas. Multiple sets of push cylinders 291 push the fixed shell 295, causing the groove 296 on the inner wall of the fixed shell 295 to lock the furnace cover 12. At the same time, the fixing rod 3 on the inner wall of the fixed shell 295 will be locked into the fixing hole 13 on the furnace cover 12. Then, the cylinder 26 is activated, and the cylinder 26 pushes the mounting seat 28 upward along the limiting post 24. The push cylinder 291 on the mounting seat 28 drives the furnace cover 12 to lift upward. At the same time, the mounting seat 28 will slide upward along the sliding groove 294 on the outer wall of the mounting box 21 through the slide rail 293 installed on its outer wall. With the help of the limiting post 24, the furnace cover 12 will not shake during the upward movement, thereby avoiding malfunctions of the refining furnace 1 during use.

[0029] In one embodiment of this application, as shown in Figure 1 and Figure 4 As shown, the refining furnace 1 includes a furnace body 11 and a furnace cover 12, wherein the furnace cover 12 is disposed on the furnace body 11, and fixing holes 13 are respectively provided on the outer wall of the furnace cover 12.

[0030] Specifically, when using refining furnace 1 to perform secondary refining of molten steel, the molten steel is put into furnace body 11, and then the furnace cover 12 is closed for refining.

[0031] In one embodiment of this application, such as Figure 3 As shown, the inner wall of the fixed shell 295 is provided with corresponding fixing rods 3, and the fixing rods 3 are symmetrically arranged about the central axis of the fixed shell 295.

[0032] It is understood that the function of the fixing rod 3 described in this embodiment is to fix the position of the furnace cover 12 when the fixing shell 295 drives the furnace cover 12 to move upward.

[0033] In one embodiment of this application, such as Figure 4 As shown, a sealing assembly 4 is provided on the inner wall of the furnace cover 12. The sealing assembly 4 includes a sealing ring 42.

[0034] The inner wall of the furnace cover 12 is provided with a sealing groove 41, and the sealing ring 42 is set in the sealing groove 41.

[0035] It is understood that the function of the sealing ring 42 described in this embodiment is to prevent heat loss from the inside of the furnace body 11 during the secondary refining of molten steel.

[0036] Working principle: When the refining furnace 1 completes the secondary refining of the molten steel, the pusher cylinder 291 is activated. Multiple pusher cylinders 291 push the fixed shell 295, causing the groove 296 on the inner wall of the fixed shell 295 to lock the furnace cover 12 in place. Simultaneously, the fixing rod 3 on the inner wall of the fixed shell 295 engages with the fixing hole 13 on the furnace cover 12. Then, the cylinder 26 is activated. The cylinder 26 pushes the mounting base 28 upward along the limiting post 24, and drives the furnace cover 12 to lift upward through the push cylinder 291 on the mounting base 28. At the same time, the mounting base 28 will slide upward along the sliding groove 294 on the outer wall of the mounting box 21 through the slide rail 293 installed on its outer wall. With the help of the limiting post 24, the furnace cover 12 will not shake during the upward movement, thereby avoiding malfunctions of the refining furnace 1 during use.

[0037] In summary, when it is necessary to control the lifting and lowering of the furnace cover 12 of the refining furnace 1, the position of the furnace cover 12 is fixed by the fixing rod 3, and then the position of the mounting base 28 is limited by the cooperation of the limiting column 24 and the slide rail 293, thereby controlling the shaking of the furnace cover 12 and preventing malfunctions during the use of the refining furnace 1.
