Description

Technical Field

[0001] The present invention belongs to the technical field of steel rolling equipment in the metallurgical industry, and specifically relates to an integrated waterproof and splashproof baffle and a cold rolling unit, which are used for blocking and guiding polishing liquid, smoothing liquid, etc. in a cold rolling skin pass mill and smooth pass mill. Background Art

[0002] During the strip leveling and skinning process, the cleanliness and lubrication status of the strip and roller surface will directly affect the product quality. In order to clean the strip surface and the working roller surface and provide appropriate lubrication during leveling, the cold rolling skin pass mill and skin pass mill are generally equipped with multiple spray beams at the entrance, the most common of which are the upper and lower plate surface pre-spraying, the upper and lower working roller spray beams, etc. While cleaning the strip and roller surface and improving the lubrication effect, the accompanying problem is that part of the skin pass liquid gathers from both sides of the strip width to the outlet side as the working roller rotates, and another part gathers from the gap between the upper working roller and the middle roller, and the gap between the upper middle roller and the upper support roller to the middle, and drips onto the strip.

[0003] As the requirements for the surface quality of steel plates become higher and higher, how to eliminate the residual traces of finishing liquid on the surface of the strip has become a crucial step in quality control. Generally, an anti-entanglement guide is configured on the exit side of the upper working roll. In theory, the anti-entanglement guide is infinitely close to the roller surface of the working roll in the working state, so that part of the finishing liquid brought by the roller rotation falls onto the anti-entanglement guide due to gravity. At the same time, the anti-entanglement guide is provided with a guide groove to drain the liquid to both sides. In practical applications, in order to prevent the anti-entanglement guide from scratching the roller surface, the distance between the roller surface and the end of the anti-entanglement guide is often increased, even reaching tens of millimeters, so it cannot effectively block the finishing liquid. Summary of the invention

[0004] The purpose of the invention is to overcome the problem that the existing anti-entanglement guide plate cannot effectively block the finishing liquid and thus affects the production quality of the strip steel.

[0005] To this end, the present invention provides an integrated waterproof splash shield, comprising two arc guide plates arranged side by side and spaced apart, the inner surface of the arc guide plate is provided with a layer of water-absorbing material, an anti-splash guide plate is connected between the two arc guide plates, the anti-splash guide plate is provided with a guide piece located on one side of the inner surface of the arc guide plate to guide liquid to the arc guide plate, and the arc guide plate is provided with a mounting piece for installing and fixing the arc guide plate.

[0006] Furthermore, the arc-shaped guide plate is provided with an oblong hole, and the end of the splash-proof guide plate is detachably fixed in the oblong hole by a locking nut.

[0007] Furthermore, the guide member includes a plurality of guide strips, which are arranged at intervals along an axial direction perpendicular to the splash guard guide plate, the guide strips are higher in the middle and lower at both ends, and the two ends of the guide strips extend to the arc guide plates on both sides respectively.

[0008] Furthermore, the width of the guide plate strip does not exceed the thickness of the water-absorbing material layer on the arc-shaped guide plate.

[0009] Furthermore, the mounting member is a mounting plate, and the mounting plate is provided with through holes for bolt fixing.

[0010] Furthermore, a gasket group is provided on one side of the mounting plate.

[0011] Furthermore, the splash-proof guide plate is made of a rectangular steel pipe.

[0012] In addition, the present invention also provides a cold rolling mill unit, comprising upper and lower working rolls, bearing seats arranged at both ends of the working rolls, and the above-mentioned integrated waterproof splash shield; the integrated waterproof splash shield is arranged on the outlet side of the upper working roll, and the two arc guide plates are respectively fixed to the end covers of the bearing seats at both ends of the upper working roll through their mounting parts, and the inner surface of the arc guide plate faces the roll surface of the upper working roll, and the guide member of the splash shield guide plate is located at a position infinitely close to the roll surface of the upper working roll and does not interfere with the operation of the upper working roll.

[0013] Furthermore, the curvature of the arc-shaped guide plate is consistent with the curvature of the roll surface of the upper working roll.

[0014] Furthermore, the axis of the splash guard guide plate is arranged parallel to the axis of the upper working roll.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The integrated waterproof and splash-proof baffle provided by the present invention can better seal and guide the finishing liquid at the roller gap through the design of the arc guide plate and the guide member on the splash-proof guide plate, effectively avoiding the situation where the strip outlet is contaminated with liquid, and improving the production quality of the strip.

[0017] (2) The integrated waterproof and splash-proof baffle provided by the present invention can be directly installed on the working roll, saving space and being closer to the roll surface of the working roll. While avoiding interference with the end of the anti-entanglement guide plate, it can better block and guide the finishing fluid.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "multiple" and "several" mean two or more.

[0026] like Figure 1 and Figure 2As shown, this embodiment provides an integrated waterproof splash shield, including two arc guide plates 3 arranged side by side and spaced apart, the inner surface of the arc guide plates 3 is provided with a water-absorbing material layer 8, and an anti-splash guide plate 5 is connected between the two arc guide plates 3, and the anti-splash guide plate 5 can play a supporting and connecting role for the two arc guide plates 3, thereby ensuring the rigidity of the integrated waterproof splash shield, and the anti-splash guide plate 5 is provided with a guide member 6 for guiding the liquid to the arc guide plate 3 on one side of the inner surface of the arc guide plate 3, and the arc guide plate 3 is provided with a mounting member 9 for mounting and fixing the arc guide plate. Among them, the curvature of the arc guide plate 3 can be designed according to the structural shape of the corresponding workpiece to be installed, so that the arc guide plate 3 can be better matched and installed on the workpiece, such as for the leveling machine and the skin-finishing machine, where the workpiece is the working roller, the curvature of the arc guide plate 3 matches the curvature of the roller surface of the working roller. In this embodiment, the arc guide plate 3 is installed at both ends of the workpiece, and the excess liquid introduced from the outside of the workpiece is absorbed by the water-absorbing material layer 8 on the arc guide plate 3. At the same time, the guide member 6 on the splash-proof guide plate 5 is used to guide the liquid in the middle of the workpiece to the two ends to be absorbed by the water-absorbing material layer 8 on the arc guide plate 3, thereby achieving the blocking and diversion of the liquid in the workpiece.

[0027] The structure of the mounting member is detailed. The mounting member 9 is a mounting plate, which is fixed to the end of the arc-shaped guide plate 3. The mounting plate is provided with a through hole 10 for bolt fixing. The mounting plate is detachably connected to the working member by bolts, thereby realizing a detachable connection between the integrated waterproof splash shield and the working member. Furthermore, a gasket group 2 is provided on one side of the mounting plate to facilitate the installation of the mounting plate.

[0028] In a detailed implementation, for the installation of the splash-proof guide plate 5, an oblong hole 4 is provided on the arc-shaped guide plate 3, and the length direction of the oblong hole 4 is perpendicular to the axial direction of the splash-proof guide plate 5. The end of the splash-proof guide plate 5 is detachably fixed in the oblong hole 4 by a locking nut, and is positioned at different positions of the oblong hole 4 of the arc-shaped guide plate 3 by the locking nut, so that the position of the guide member 6 on the splash-proof guide plate 5 relative to the working part can be slightly adjusted, so as to better guide the liquid without affecting the normal operation of the working part. Furthermore, the splash-proof guide plate 5 is made of a rectangular steel pipe, which ensures the rigidity of the splash-proof guide plate 5, and further ensures the good rigidity of the entire integrated waterproof splash-proof baffle.

[0029] As an embodiment, the guide member 6 includes a plurality of guide strips, which are arranged at intervals along the axial direction perpendicular to the splash-proof guide plate 5, the guide strips are high in the middle and low at both ends, forming a herringbone structure, and the two ends of the guide strips extend to the arc guide plates 3 on both sides, so that after the liquid in the middle of the workpiece is thrown onto the guide strips, it can be guided to both sides along the guide strips under its own gravity and absorbed by the water-absorbing material layer 8 of the arc guide plate 3. Further, in order to better absorb the liquid guided by the guide strips, the width of the guide strips does not exceed the thickness of the water-absorbing material layer 8 on the arc guide plate 3, so that the liquid flowing down along the guide strips can be completely absorbed by the water-absorbing material layer 8, and at the same time, when the arc guide plate 3 is close to the workpiece, the guide strips will not affect the normal operation of the workpiece.

[0030] In addition, this embodiment also provides a specific application of the above-mentioned integrated waterproof and splash-proof shield in a cold rolling mill, such as a cold rolling skin pass mill and a pass mill. Figure 3 As shown, the cold rolling mill unit includes an upper working roll 7, a lower working roll, a bearing seat 1 arranged at both ends of the working rolls, and the above-mentioned integrated waterproof splash shield; the integrated waterproof splash shield is arranged at the outlet side of the upper working roll 7, and the distance between the mounting members 9 on both sides of the integrated waterproof splash shield is set according to the size of the upper working roll 7 after assembly, and the mounting members 9 on the two arc guide plates 3 are respectively fixed to the end covers of the bearing seat 1 at both ends of the upper working roll 7 by bolts, and the width of the arc guide plate 3, that is, the distance between the arc guide plates 3 on both sides, It is set according to the maximum width of the strip; during installation, the inner surface of the arc guide plate 3 (i.e. the side where the water-absorbing material layer 8 is set) faces the roller surface of the upper working roller 7, and the water-absorbing material layer 8 on the arc guide plate 3 absorbs the finishing liquid thrown from the outside of the strip width to avoid more splashing. At the same time, the position of the guide piece of the splash-proof guide plate 5 is adjusted to make it infinitely close to the roller surface of the upper working roller 7 without interfering with the normal operation of the upper working roller 7. After adjustment, the two ends of the splash-proof guide plate 5 are fixed on the arc guide plate 3 with locking nuts.

[0031] Of course, the anti-entanglement guide plate 11 and the above-mentioned integrated waterproof and splash-proof baffle can be installed near the roller surface of the existing upper working roller 7 at the same time. The installation of the integrated waterproof and splash-proof baffle avoids interference with the end of the anti-entanglement guide plate 11. The integrated waterproof and splash-proof baffle can effectively enhance the blocking of the finishing liquid by the existing anti-entanglement guide plate 11, thereby further better realizing the blocking and diversion of the finishing liquid.

[0032] Optimally, the curvature of the arc guide plate 3 is designed to be consistent with the curvature of the roll surface of the upper working roll 7, so as to ensure that the arc guide plate 3 and the upper working roll 7 can be better matched and installed, which can not only ensure that the arc guide plate 3 can be as close to the roll surface of the upper working roll 7 as possible, but also save the installation space of the arc guide plate 3. Further, the axis of the splash-proof guide plate 5 is arranged parallel to the axis of the upper working roll 7, so as to better guide the finishing liquid at the roll gap between the upper and lower working rolls.

[0033] In summary, installing the integrated waterproof and splash-proof baffle provided by the present invention on the working roll of the cold rolling mill saves space and can be closer to the roll surface of the working roll, so that the finishing liquid at the roll gap can be better sealed and diverted, avoiding liquid at the strip outlet and improving the strip production quality.

[0034] The above examples are merely illustrative of the present invention and do not constitute a limitation on the protection scope of the present invention. All designs that are the same or similar to the present invention fall within the protection scope of the present invention.
