Description

Technical Field

[0001] The utility model relates to the field of stabilizing rollers in metallurgical processing, in particular to a stabilizing roller device for a furnace nose. Background Art

[0002] During the hot-dip galvanizing production process, if the moving speed of the strip in the furnace nose is not stabilized, the strip may shake during the movement. When the shaking strip is immersed in the zinc liquid, the zinc liquid will fluctuate. As a result, the fluctuating zinc liquid will be unevenly attached to the surface of the strip, resulting in uneven thickness of the zinc layer on the strip surface. Therefore, people usually set a stabilizing roller on the furnace nose to stabilize the moving speed of the strip, so as to avoid the strip shaking and causing the zinc liquid to adhere unevenly to the strip surface.

[0003] The traditional stabilizing roller device places the stabilizing roller transmission mechanism on the upper part of the furnace nose, uses a pulley to drive the stabilizing roller body to rotate, and uses electrical control to keep the stabilizing roller speed consistent with the strip speed. However, the upper part of the furnace nose is not stable and there will still be slight shaking, which may cause the belt to slip. The belt slip will make the actual speed of the stabilizing roller inconsistent with the speed of the strip, resulting in scratches on the surface of the strip. In addition, after the belt has been used for a period of time, the belt itself will expand due to heat and easily slip, which will also scratch the surface of the strip. As a result, many steel mills need to shut down for a long time for maintenance after using the stabilizing roller device for a period of time to replace the belt and fine-tune the distance between the center of the reduction motor and the center of the stabilizing roller body.

[0004] In addition, the traditional stabilizing roller device forms a fixed wrap angle because the distance between the center of the stabilizing roller and the strip is fixed. When facing strips of different widths and thicknesses, this wrap angle needs to be adjusted to adapt to different strip tensions. However, the wrap angle formed by the traditional stabilizing roller device is not adjustable, and it is necessary to adjust the wrap angle through the swinging operation of the furnace nose swinging device, which can easily cause the strip to be not in the center of the furnace nose. Therefore, when using the slag removal furnace nose tip, the strip may be scratched due to the narrow slag removal furnace nose tip channel. Utility Model Content

The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0025] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0026] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0027] refer to Figures 1 to 4 A stabilizing roller device for a furnace nose according to a preferred embodiment of the utility model will be described in detail below. The stabilizing roller device for the furnace nose is arranged on an inclined furnace nose 90, wherein the furnace nose 90 has a channel 901, and the channel 901 is used for strip movement.

[0028] The stabilizing roller device for the furnace nose includes a stabilizing roller body 10 and a transmission assembly 20, wherein the stabilizing roller body 10 is rotatably mounted on the furnace nose 90, and the stabilizing roller body 10 is arranged to pass through the channel 901 of the furnace nose 90, and the stabilizing roller body 10 can be driven by the transmission assembly 20 to rotate on the furnace nose 90, so that when the strip moves in the channel 901, the transmission assembly 20 is driven to make the rotation speed of the stabilizing roller body 10 consistent with the moving speed of the strip, thereby preventing the strip from shaking when moving.

[0029] The transmission assembly 20 includes a transmission member 21 and a driving member 22, wherein one end of the transmission member 21 is connected to the end of the stabilizing roller body 10 and is coaxial with the center of the stabilizing roller body 10, and the other end of the transmission member 21 is installed on the driving end of the driving member 22, so that the transmission member 21 can be driven by the driving member 22 to rotate the stabilizing roller body 10.

[0030] It can be understood by those skilled in the art that, since the transmission member 21 is connected to the stabilizing roller body 10, when the transmission member 21 rotates, the stabilizing roller body 10 is driven to rotate along the axial direction of the transmission member 21, so that when the strip moves in the channel 901 of the furnace nose 90, the driving member 22 is started to drive the stabilizing roller body 10 to rotate, so that the rotation speed of the stabilizing roller body 10 is consistent with the movement speed of the strip.

[0031] Preferably, one end of the transmission member 21 is rigidly connected to the end of the stabilizing roller body 10. Therefore, compared with the existing pulley driving the stabilizing roller body 10 to rotate, the transmission member 21 is rigidly connected to the stabilizing roller body 10 without the occurrence of belt slippage or belt expansion, which causes the moving speed of the strip to be inconsistent with the rotation speed of the stabilizing roller body 10.

[0032] Preferably, the transmission member 21 is implemented as a coupling. The driving member 22 is implemented as a transmission motor with a variable frequency control function.

[0033] More preferably, the transmission assembly 20 also includes a fixed bracket 23, one end of the fixed bracket 23 is fixedly mounted on the driving member 22, and the other end of the fixed bracket 23 is grounded, so that when the driving member 22 is driven, the fixed bracket 23 can stabilize the driving member 22, thereby preventing the driving member 22 from shaking due to its own driving force. At the same time, the fixed bracket 23 can also bear part of the bearing pressure of the transmission member 21.

[0034] In this way, the transmission assembly 20 can stably drive the stabilizing roller body 10 to rotate, and make the rotation speed of the stabilizing roller body 10 consistent with the moving speed of the steel strip, thereby preventing scratches on the surface of the steel strip.

[0035] It is worth mentioning that the distance between the center of the stabilizing roller body 10 and the strip moving in the channel 901 is fixed to form a fixed wrap angle, but for galvanized sheets with different strip widths and thicknesses, this wrap angle needs to be adjusted to adapt to different strip tensions. Therefore, the stabilizing roller device for the furnace nose also includes an adjustment component 30, which can automatically adjust the wrap angle formed by the center of the stabilizing roller body 10 and the strip according to different strip specifications and speed changes to meet on-site production needs. In other words, the stabilizing roller body 10 can also be moved to the furnace nose 90.

[0036] In one embodiment, the adjustment component 30 is configured as an elevator, wherein the elevator is installed on the outer wall of the furnace nose 90, and one end of the stabilizing roller body 10 is installed on the telescopic end of the elevator, so that when the elevator is started to drive the telescopic end of the elevator, the stabilizing roller body 10 can be driven by the elevator and move along the telescopic direction of the telescopic end of the elevator, thereby enabling the wrap angle formed by the center of the stabilizing roller body 10 and the strip to be adjusted, so that when the strips of different specifications or the speed of the strips change, the wrap angle formed by the center of the stabilizing roller body 10 and the strip can be increased or decreased accordingly.

[0037] In another embodiment, the adjustment assembly 30 includes a driving unit 31 and at least one driving member 32, wherein the driving unit 31 is installed on the outer wall of the furnace nose 90. Each of the driving members 32 includes a driving member 321 and a connecting member 322, wherein the driving member 321 is provided with an input end and a driving end, wherein the input end of the driving member 321 is driven and rotatably connected to the driving end of the driving unit 31, and the driving end of the driving member 321 is connected to one end of the connecting member 322, and can drive the connecting member 322 to move when the input end is driven by the driving unit 31. The other end of the connecting member 322 is rotatably connected to one end of the stabilizing roller body 10 by installing a bearing.

[0038] It can be understood by those skilled in the art that the driving unit 31 is started to drive the driving end of the driving unit 31, so that the input end of the driving member 321 is driven to rotate, thereby causing the driving end of the driving member 321 to move, thereby causing the connecting member 322 to be driven to move along the moving direction of the driving end of the driving member 321, thereby causing the stabilizing roller body 10 connected to the connecting member 322 to be driven to move in the same direction as the moving direction of the connecting member 322, and therefore, the wrap angle formed by the center of the stabilizing roller body 10 and the strip steel can be adjusted.

[0039] Preferably, the number of the driving components 32 is set to two, and the two driving components 32 are aligned and arranged on both sides of the furnace nose 90, and are respectively connected to the two end portions of the stabilizing roller body 10, and the input ends of the driving members 321 of the two driving components 32 are kept connected by multiple couplings, so that when the input end of one of the driving members 321 is driven by the driving unit 31, the input end of the other driving member 321 can be driven to rotate, thereby preventing the stabilizing roller body 10 from being in a tilted posture when the position is adjusted by a single driving component 32. At the same time, relative to the single driving component 32 adjusting the position of the stabilizing roller body 10, the two driving components 32 can bear the weight of the stabilizing roller body 10 together to reduce the adjustment pressure of the single driving component 32.

[0040] Preferably, the driving unit 31 is implemented to include a reduction motor with a frequency conversion control function. The driving member 321 is implemented to include a screw lifting platform.

[0041] Preferably, the adjustment assembly 30 further includes a display member 33, which is disposed on the connecting member 322 of the driving member 32 to display the adjusted distance of the stabilizing roller body 10. In other words, the display member 33 can display the distance that the stabilizing roller body 10 is moved under the control of the driving unit 31, so that the wrap angle formed by the center of the stabilizing roller body 10 and the strip steel can be accurately adjusted.

[0042] In a preferred embodiment, the display member 33 is configured as a scale 331 and a pointer 332, wherein the scale 331 is installed on the furnace nose 90 and fits below the pointer 332, and a scale value is set on one side of the scale 331. The pointer 332 is installed on one side of the connecting member 322, and the pointer 332 is movably connected to the side of the scale 331 where the scale value is set. It can be understood that when the connecting member 322 drives the pointer 332 to move, the pointer 332 can move to the scale 331 and finally stay at a certain position where the scale 331 sets the value to display the moving distance of the pointer 332. Therefore, the distance that the connecting member 322 drives the pointer 332 to move can be displayed, so that the distance that the stabilizing roller body 10 is adjusted by the adjustment component 30 can be displayed.

[0043] In a modified example of the above preferred embodiment, the scale 331 of the display member 33 is installed on one side of the connecting member 322, and the side of the scale 331 where the value is set is slidably connected to the pointer 332. The pointer 332 is installed on the furnace nose 90 and fits above the scale 331, so that the scale 331 can be driven by the connecting member 322 to move relative to the pointer 332, so that a certain position where the value of the scale 331 is set corresponds to the pointer 332.

[0044] In this way, the adjustment component 30 can not only adjust the position of the stabilizing roller body 10, but also accurately display the adjusted distance of the stabilizing roller body 10, so that the wrap angle formed by the stabilizing roller body 10 and the strip can be accurately adjusted. Therefore, when strips of different specifications enter the channel 901 of the furnace nose 90 or the speed of the strip entering the channel 901 changes, the adjustment component 30 is driven to adjust the wrap angle formed by the stabilizing roller body 10 and the strip, thereby meeting production needs.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized.
