Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling equipment technology, and in particular to a vertical roll device for the exit side of the finishing mill in a steel rolling plant. Background Technology
[0002] The side vertical rolls on the exit side of the finishing mill in a steel rolling mill are devices to prevent the rolled workpiece from being scratched by the side baffle. During the rolling process, the workpiece rotates due to friction with the roller table of the side vertical rolls, preventing scratches from forming on the surface of the workpiece. However, because the side vertical rolls are used at high temperatures for a long time, the roller table often stops rotating, and they are not easy to replace, which can easily cause scratches on the surface of the rolled workpiece and compromise the product quality.
[0003] Therefore, it is necessary to modify the existing side roller structure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a vertical roller device for the exit side of the finishing mill in a steel rolling mill, which is less likely to experience roller table failure, extends the service life of the roller table, and reduces maintenance and replacement time.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A vertical roll assembly for the finishing mill exit side of a steel rolling mill includes an extended roller table, an upper bearing seat at the upper end of the roller table, a lower bearing seat at the lower end of the roller table, and a fixed baffle on one side of the roller table. The upper back of the fixed baffle has a first groove for fixing the upper bearing seat, and the lower back has a second groove for fixing the lower bearing seat. The upper bearing seat uses a self-aligning roller bearing, and the lower bearing seat uses a pressure bearing.
[0007] A further improvement of this utility model is that the height of the roller conveyor is increased by 400mm compared to the original roller conveyor.
[0008] A further improvement of this utility model is that both the first slot and the second slot are vertically arranged on the back of the fixed baffle.
[0009] A further improvement of this utility model is that both the first slot and the second slot are made of welded steel plates.
[0010] A further improvement of this utility model is that both the first card slot and the second card slot are insert-type structures.
[0011] A further improvement of this utility model is that the fixed baffle is installed at a 15° angle to the outside.
[0012] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:
[0013] 1. This utility model extends the roller table of the side vertical roll on the exit side of the finishing mill in a steel rolling mill by 400mm, uses self-aligning roller bearings for the upper bearing seat and pressure bearings for the lower bearing seat, so that the upper and lower bearing seats are further away from the rolled workpiece; reduces the bearing temperature, making the side vertical roll less prone to seizing; extends the service life of the roller table of the side vertical roll and reduces maintenance and replacement time.
[0014] 2. In this utility model, a slotted plate structure is provided on the back of the fixed baffle, which allows the upper and lower tile seats and roller conveyor to be directly inserted into the slot from above, which facilitates the daily maintenance and disassembly of the side vertical roller and saves time in replacing the side vertical roller.
[0015] 3. In this utility model, the fixed baffle is tilted outward at 15° during installation, and the roller conveyor is also tilted outward. Even when the roller conveyor is worn, the rolled piece can collide with the bottom of the roller conveyor without causing scratches on the surface of the rolled piece, thus further extending the service life of the roller conveyor.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0024] like Figure 1-2 As shown, a vertical roll assembly for the finishing mill exit side of a steel rolling mill includes a roller conveyor 2 with an extended height, an upper bearing seat 1 located at the upper end of the roller conveyor 2, a lower bearing seat 3 located at the lower end of the roller conveyor 2, and a fixed baffle 4 fixed to one side of the roller conveyor 2. The upper back of the fixed baffle 4 is provided with a first slot 4-1 for fixing the upper bearing seat 1, and the lower back is provided with a second slot 4-2 for fixing the lower bearing seat 3. The upper bearing seat 1 adopts a self-aligning roller bearing, and the lower bearing seat 3 adopts a pressure bearing.
[0025] Furthermore, the height of roller conveyor 2 is increased by 400mm compared to the original roller conveyor.
[0026] In this embodiment, the roller conveyor 2 is lengthened by 400mm, the upper bearing seat 1 adopts a self-aligning roller bearing, and the lower bearing seat 3 adopts a pressure bearing, so that the upper bearing seat 1, the lower bearing seat 3 and the workpiece are at a greater distance, which reduces the bearing temperature and makes it less likely for the side vertical roller to seize up.
[0027] Furthermore, the first slot 4-1 and the second slot 4-2 are both vertically disposed on the back of the fixed baffle 4.
[0028] Furthermore, both the first card slot 4-1 and the second card slot 4-2 are made of welded steel plates.
[0029] Furthermore, such as Figure 2 As shown, both the first card slot 4-1 and the second card slot 4-2 are insert-type structures.
[0030] In this embodiment, the insert plate structure allows the upper tile seat 1, lower tile seat 3, and roller conveyor 2 to be directly inserted into the first slot 4-1 and the second slot 4-2 on the back of the fixed baffle 4, which facilitates the daily maintenance and disassembly of the side vertical roller and saves the replacement time of the side vertical roller.
[0031] Furthermore, the fixed baffle is installed at a 15° angle to the outside.
[0032] In this embodiment, because the fixed baffle 4 is inclined to the outside, the roller table 2 is also inclined to the outside. Even when the roller table 2 is worn, the workpiece can collide with the bottom of the roller table 2 without causing scratches on the surface of the workpiece, thus further extending the service life of the roller table 2.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
