Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of steel rolling technology, and particularly relates to an import sliding guide cooling water pipe. BACKGROUND

[0002] The import guide of a rolling mill mainly guides and supports a rolled piece to enter the roll gap of the rolling mill for rolling according to a specified route. Common import guides are divided into sliding guides and rolling guides. Different forms of guides are designed and installed according to different material sizes and rolling mill characteristics. When the material size is large and the height-width ratio is small, a sliding import guide is generally used. The sliding import guide plays a guiding role on one hand and supports the rolled piece to prevent the rolled piece from tilting and falling during deformation in the roll gap on the other hand. Therefore, the guide is in contact and friction with the high-temperature rolled piece during the process of supporting the rolled piece. Wear-resistant blocks are generally used at the contact position of the guide and the rolled piece to prolong the online service life of the guide. However, the wear-resistant blocks still have problems such as fast wear, fragmentation, and iron sticking during contact with the high-temperature rolled piece. The guide must be replaced in time to ensure normal production after the wear-resistant blocks of the guide are damaged, which causes frequent replacement of the guide and seriously affects the production capacity of the rolling line and increases the labor intensity of the post personnel. SUMMARY

[0003] The utility model aims to provide an import sliding guide cooling water pipe to solve the problem that the import guide wear-resistant blocks are easily worn, fragmented, or iron-stuck due to the influence of high-temperature rolled piece friction during guide assembly, which leads to guide damage and frequent replacement of the guide, seriously affecting the stable operation of production.

[0004] The technical scheme of the utility model is as follows: an import sliding guide cooling water pipe, the guide includes a guide upper cover plate and a guide wear-resistant block, and further includes a cooling water pipe. The cooling water pipe includes an L-shaped elbow pipe. One end of the L-shaped elbow pipe is provided with a quick connector. A vertical pipe provided with the quick connector is arranged in the same direction along the length of the guide. Two water nozzles are arranged on the horizontal pipe at the other end of the L-shaped elbow pipe. The two water nozzles are directed towards the guide wear-resistant block. The spacing between the two water nozzles is consistent with the spacing of the friction surface of the guide wear-resistant block.

[0005] Further, the horizontal pipe of the L-shaped elbow pipe provided with the water nozzles is provided with a base at the bottom. The base is provided with uniformly distributed screw holes.

[0006] Further, an included angle is arranged between the vertical pipe provided with the quick connector at one end of the L-shaped elbow pipe and the base.

[0007] Further, the spray head of the water nozzle is in the shape of a flat head.

[0008] The beneficial effects of this utility model are as follows: The imported sliding guide cooling water pipe provided by this utility model is mainly composed of quick connectors, L-shaped bends, water nozzles, bases and other components. The rolling mill cooling water is led to the cooling water pipe through the quick connector of the metal hose. The water nozzle of the cooling water pipe sprays water onto the wear-resistant blocks inside the guide, cooling and lubricating the wear-resistant blocks. During the rolling process, it effectively reduces the temperature and temperature alternating stress of the guide wear-resistant blocks, greatly reduces the wear and breakage of the guide wear-resistant blocks, extends the service life of the guide, solves the problem of frequent guide replacement after the wear-resistant blocks are damaged, saves spare parts consumption, improves the rolling mill operation efficiency, reduces the labor intensity of the post, and increases the output of the rolling line.
