Description

Technical Field

[0001] This utility model relates to the field of hot-rolled strip steel production technology, and in particular to a hot-rolled embedded outlet guide plate device. Background Technology

[0002] The production of hot-rolled strip steel involves rolling steel billets through two-high and four-high mills with different reduction rates to gradually produce finished strip steel. During rolling, pre-installed guide plates are used to transition the steel head as it is rolled out by the mill rolls; otherwise, if the head is not properly aligned, it could cause a production accident.

[0003] Currently, the exit guide plates are all installed on the mill frame, which has retaining rings for installation. Due to the limited internal space of the mill frame, when installing new rolls or replacing rolls, the rolls must be installed in the mill first, and then the exit guide plates must be manually moved to the mill exit position for installation. This not only prevents the use of large hoisting machinery, increasing the labor intensity of personnel and the safety risks of operating in confined spaces, but also results in low installation efficiency, delaying production time and affecting output. Utility Model Content

[0025] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0027] Reference Attachment Figure 1-4 This utility model provides a hot-rolling embedded exit guide plate device, which includes: a roll bearing housing 100 and a guide plate assembly 200. The roll bearing housing 100 is provided with two sets opposite each other for mounting the rolls 300 of the rolling mill. The top of the two sets of roll bearing housings 100 is provided with slots 110, and the top and side openings of the slots 110 are used to mount the guide plate assembly 200. The guide plate assembly 200 is located between the two sets of roll bearing housings 100, and its two ends are respectively inserted into the two sets of slots 110. The bottom of the guide plate assembly 200 is provided with an arc-shaped surface, the shape of which is adapted to the rolls 300 mounted on the roll bearing housing 100.

[0028] By adopting the above technical solution, when installing or replacing the roll 300, the roll 300 is first connected and fixed to the roll bearing housing 100. Then, a lifting rope is tied to the guide plate assembly 200, and a crane is used to pull the lifting rope to transfer the guide plate assembly 200 and lower it into the slot 110 at the top of the roll bearing housing 100. Finally, the roll 300, roll bearing housing 100, and guide plate assembly 200 are pushed together into the frame, and the roll bearing housing 100 is installed in place. Compared with the existing technology, the above solution improves the mechanization of equipment installation and maintenance operations, reduces the labor intensity of personnel and the safety risks of working in confined spaces, and improves work efficiency, reducing the impact of operation time on production efficiency and output.

[0029] In the above technical solution, the bottom of the guide plate assembly 200 is provided with an arc-shaped surface to adapt to the outer contour shape of the roll 300 and avoid installation obstruction. In addition to considering the installation problem, the frictional loss generated by the guide plate assembly 200 on the roll 300 during operation should also be considered. Therefore, when implementing this technical solution, attention should also be paid to ensuring that there is a certain gap between the arc-shaped surface and the outer surface of the roll 300 to avoid the guide plate assembly 200 rubbing against the roll surface of the roll 300, which would cause damage to the roll surface and thus affect the quality of the hot-rolled product.

[0030] Reference Attachment Figure 2 In this embodiment, the guide plate assembly 200 includes a guide plate 210 and a mounting plate 220. The guide plate 210 is disposed on the top of the mounting plate 220 in the same direction and is centered with the mounting plate 220, so that the weight on both sides of the guide plate assembly 200 is the same, reducing mechanical wear during operation. The length of the guide plate 210 is less than the length of the mounting plate 220, and the width of the guide plate 210 is greater than the width of the mounting plate 220, with one end of the guide plate 210 extending beyond the mounting plate 220 in the width direction. The two ends of the mounting plate 220 in the length direction are respectively provided with inserts 250, which are inserted into slots 110. The guide plate assembly 200, constructed by the guide plates 210 and mounting plates 220 with different heights and widths, can better adapt to the installation space between the two sets of roll bearing housings 100 and better fit the outer contour of the roll surface of the roll 300.

[0031] The aforementioned arc-shaped surface includes a first arc-shaped surface 230 and a second arc-shaped surface 240. The first arc-shaped surface 230 is located at the bottom of the guide plate 210, and the second arc-shaped surface 240 is located at the bottom of the mounting plate 220. The bottom edge of the first arc-shaped surface 230 is connected to the top edge of the second arc-shaped surface 240 to more smoothly adapt to the outer contour of the roll surface of the roll 300.

[0032] In this embodiment, the cross-sectional shape of the slot 110 at the top of the roll bearing housing 100 is adapted to the contour of the inserts 250 at both ends of the mounting plate 220; the insert 250 includes a limiting part 251 and a connecting part 252, the two ends of the connecting part 252 are respectively connected to the limiting part 251 and the mounting plate 220, and the width of the limiting part 251 is greater than the width of the connecting part 252. The limiting part 251 and the connecting part 252 form a T-shape, so the cross-sectional shape of the slot 110 is also T-shaped. When the guide plate assembly 200 is transported to the slot 110 by the crane and the hoisting rope, the limiting part 251 and the connecting part 252 fall from top to bottom into the slot 110. When the roll 300, the roll bearing housing 100 and the guide plate assembly 200 are moved and pushed into the arch frame, the T-shaped inserts 250 with opposite directions at both ends of the mounting plate 220 can form a tie with the roll bearing housings 100 at both ends. The tie force generated can prevent the mounting plate 220 from separating from the roll bearing housing 100, and at the same time prevent the roll bearing housings 100 on both sides from separating, which would cause the roll bearing housings 100 and the roll 300 to be unstable. This ensures that after being installed in the arch frame, the mill and the roll 300 operate normally, avoiding unplanned skewing, wear, and unstable connection, and reducing equipment wear.

[0033] When the roll bearing housing 100 is moved, the guide plate assembly 200 may be shaken out of the slot 110 due to the uneven bottom surface inside the arch frame. Therefore, in this embodiment, a first positioning pin hole 120 is provided on the roll bearing housing 100. One end of the first positioning pin hole 120 is connected to the slot 110 for inserting a positioning pin 400. The positioning pin 400 restricts the guide plate assembly 200 in the slot 110.

[0034] For specific implementation, please refer to the appendix. Figure 3 The first positioning pin hole 120 can be located above the guide plate assembly 200, and a set is provided on each side of the guide plate assembly 200, so that the positioning pin 400 is inserted into the slot 110 and the two sets of first positioning pin holes 120.

[0035] You can also refer to the appendix Figure 4 The first positioning pin hole 120 is positioned on the side of the guide plate assembly 200, and a second positioning pin hole 260 corresponding to the first positioning pin hole 120 is provided on the side of the guide plate assembly 200. The positioning pin 400 is inserted into the first positioning pin hole 120 and the second positioning pin hole 260.

[0036] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a slot 110 at the top of the roll bearing housing 100, the guide plate assembly 200 can be hoisted using hoisting equipment in a large space outside the frame, which improves the mechanization of equipment installation and maintenance operations, reduces the labor intensity of personnel and the safety risks of working in narrow spaces, and improves work efficiency, reducing the impact of work time on production efficiency and output; the bottom of the guide plate assembly 200 is provided with an arc-shaped surface, which can avoid the installation being obstructed by the roll 300, and there should be a certain gap between the arc-shaped surface and the outer surface of the roll 300 to avoid the guide plate assembly 200 rubbing against the roll surface of the roll 300, which would cause damage to the roll surface and thus affect the quality of hot-rolled products.
