Description

Technical Field

[0001] This utility model relates to the field of strip steel processing, and in particular to a strip steel surface quality finishing roll for a cold-rolled silicon steel continuous annealing unit. Background Technology

[0002] The continuous annealing unit for silicon steel is used to anneal and coat cold-rolled silicon steel strip after it has been rolled by a 20-roll mill. This process eliminates internal stress in the cold-rolled strip, restores its plasticity, and promotes recrystallization and grain growth. Simultaneously, the continuous annealing unit applies an insulating layer to the surface of the annealed strip, improving its mechanical properties and surface quality. The continuous annealing unit is one of the most critical units in the production of cold-rolled silicon steel.

[0003] The continuous annealing process for silicon steel is complex, involving numerous processes and equipment. Silicon steel strip first undergoes degreasing in the cleaning section of the continuous annealing unit, then enters an annealing furnace over 400 meters long for annealing. Heating causes warping of the strip. Simultaneously, due to the large number of furnace rollers and roller nodules, slight scratches and dents appear on the surface of the strip after exiting the furnace. These surface defects severely affect the quality of the subsequent coating of the insulating layer, ultimately impacting the finished product quality of the silicon steel strip. This significantly reduces the yield and first-grade product rate of high-grade, thin-gauge silicon steel strip. Therefore, a surface quality finishing roller for cold-rolled silicon steel continuous annealing units is proposed to address these issues. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a strip surface quality finishing roll for a cold-rolled silicon steel continuous annealing unit, which aims to improve the problem in the prior art that "slight scratches and dents will be generated on the surface of the strip during processing, which will affect the quality of the finished product".

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a strip surface quality finishing roller for a cold-rolled silicon steel continuous annealing unit, comprising a support shaft 3 for supporting the overall device, a fixing assembly 5 for supporting an inner sleeve 2 on the outer wall of the support shaft 3, a limiting ring 51 for restricting the installation position of other components, the limiting ring 51 being rotatable and sliding on the outer wall of the support shaft 3, the limiting ring 51 being sleeved on the outer wall of the support shaft 3, the inner sleeve 2 being fixedly connected to the outer wall of the limiting ring 51 to ensure support force, a bearing 7 for supporting the rotation of the limiting ring 51 being installed at the left end of the limiting ring 51, the inner ring of the bearing 7 being sleeved on the outer wall of the support shaft 3, a fixing groove 53 for installing bolts being provided on the outer wall of the support shaft 3, a fixing ring 52 being fixedly connected to the outer wall of the support shaft 3 by bolts, the fixing ring 52 restricting the internal structure from moving outward, and a lubrication assembly 6 for lubricating the bearing 7 being provided on the outer wall of the support shaft 3.

[0030] Reference Figure 1 - Figure 3The lubrication assembly 6 includes an oil guide ring 62 for guiding the flow of lubricating oil. The oil guide ring 62 is sleeved on the outer wall of the support shaft 3 near the left end of the bearing 7. The right end of the oil guide ring 62 is in contact with the left end of the inner ring of the bearing 7. The inner wall of the oil guide ring 62 is provided with an oil guide groove 64 for guiding the flow of lubricating oil. The inner wall of the support shaft 3 is provided with an oil delivery groove 63 for allowing lubricating oil to enter the oil guide groove 64. The oil delivery groove 63 and the oil guide ring 62 are adapted to each other. When the fixing ring 52 is installed, its right end just tightly squeezes the oil guide ring 62. At this time, the oil guide groove 64 will be just aligned with the oil delivery groove 63. The left surface of the support shaft 3 is fixedly connected with a connector 65 for connecting the oil delivery pipe 61. The inner wall of the oil guide groove 64 is threadedly connected with an oil delivery pipe 61 for delivering lubricating oil into the device. The left end of the fixing ring 52 is fixedly connected with a mounting plate 4 for fixing the whole device. The left side of the mounting plate 4 is provided with a through hole, and the whole device can be fixed to the working plane by bolts passing through the through hole.

[0031] Reference Figure 1 - Figure 3 The outer wall of the support shaft 3 is provided with a keyway to accommodate the splines. The inner walls of both the oil guide ring 62 and the fixing ring 52 are provided with splines. By providing splines, it can be ensured that the oil guide ring 62 and the fixing ring 52 can only move horizontally and cannot rotate on the outer wall of the support shaft 3. Multiple sets of mounting plates 4, fixing components 5, lubrication components 6, and bearings 7 are provided. These multiple sets of mounting plates 4, fixing components 5, lubrication components 6, and bearings 7 are symmetrically arranged about the centerline of the support shaft 3. Two sets of fixing components 5 can fix the outer sleeve 1 from both ends, thus... Ensure that the outer sleeve 1 is located at the center of the support shaft 3. The outer wall of the inner sleeve 2 is fixedly connected to the outer sleeve 1 for direct contact with the strip steel. The outer sleeve 1 is made of high-temperature resistant rubber material and has a certain elastic deformation capability, which can improve the service life of the inner sleeve 2 and prevent wear between the inner sleeve 2 and the strip steel. When using the whole device, two sets are generally required to be set up at the same time. One set is set at the inlet of the roller coating machine and the other set is set at the outlet of the roller coating machine. The two sets of devices are set at different heights, so that the upper and lower surfaces of the strip steel can be treated.

[0032] Working principle: When a correction operation is required, first, the limiting ring 51 can be fitted onto the outer wall of the support shaft 3. The limiting ring 51 will drive the bearing 7 to fit onto the outer wall of the support shaft 3. Then, the oil guide ring 62 can be fitted onto the outer wall of the support shaft 3. After that, the fixing ring 52 can be fitted onto the outer wall of the support shaft 3. Then, bolts can be used to fix the fixing ring 52 onto the outer wall of the support shaft 3. When installing the fixing ring 52 and the oil guide ring 62, it is important to ensure that the spline is aligned with the keyway for correct installation. After both sides of the structure are installed, the two sets of mounting plates 4 can be fitted onto the outer wall of the support shaft 3. Then, bolts can be used to fix the two sets of mounting plates 4 onto the working plane, thus completing the installation of the entire device.

[0033] After the entire device is installed, the oil supply pipe 61 can be installed inside the connector 65 by rotation. When lubrication is required, lubricating oil can be introduced into the oil supply groove 63 through the oil supply pipe 61. The lubricating oil will enter the oil guide groove 64 through the oil supply groove 63, and then leave the oil guide groove 64 and be sprayed onto the surface of the limiting ring 51. In this way, the limiting ring 51 can be lubricated. By adding lubricating oil, the limiting ring 51 can be guaranteed to work smoothly continuously.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
