Description

Technical Field

[0001] This utility model relates to the field of hot rolling mill roughing mill technology, specifically a practical roughing mill arch wear protection mechanism. Background Technology

[0002] Hot rolling mill roughing mills are mainly used for rapid protection of the roughing mill stand's precision, providing targeted solutions to stand damage problems, fully guaranteeing the stand's service life, avoiding reduction in stand rigidity and strength due to stand damage, and saving significant costs associated with stand replacement. Vertical roll mills consist of a stand, side pressure device, transmission device, and vertical roll system. Their main functions are descaling and side rolling. During rolling, the vertical rolls loosen the iron oxide scale on the slab surface. After the scale is loosened, high-pressure water impact achieves a better descaling effect. The main causes of wear on the mill stand include: metal fatigue wear, high-pressure water erosion during descaling, cooling water corrosion, and loosening or elongation of bolts securing the vertical roll exit and mill inlet guide plates during mill operation.

[0003] However, the protective mechanisms currently on the market are inconvenient to install and operate, which affects their protective performance and ease of use, thus reducing their efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a practical wear protection mechanism for roughing mill arches to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a practical wear protection mechanism for roughing mill arches, comprising a protective plate, a positioning sleeve inserted into the protective plate, a positioning ring fixedly installed on the surface of the positioning sleeve, and a buffer ring fixedly installed on one side of the positioning ring.

[0006] The positioning sleeve is threaded with a locking nut, and an anti-slip washer is fitted on the surface of the positioning sleeve. One side of the anti-slip washer fits against one side of the locking nut, and the other side of the anti-slip washer fits against one side of the protective plate. The protective plate, positioning sleeve, and locking nut work together to protect the components. After protection, the wear of the archway is reduced, ensuring the reliability of the rolling mill archway frame and fundamentally solving the problem of continued wear of the rolling mill archway. At the same time, it avoids damage to the archway by high-pressure water, which could cause the archway to fail in rigidity, thus ensuring the safety and stability of the equipment.

[0007] Preferably, one end of the positioning sleeve is sealed, and a round hole is provided at one end of the positioning sleeve. The round hole at one end of the positioning sleeve facilitates ventilation during use, thereby facilitating subsequent heat dissipation.

[0008] Preferably, the surface of the positioning sleeve is provided with a threaded groove, which is threadedly connected to the locking nut. The inner wall of the positioning ring is smooth and is slidably connected to the surface of the positioning sleeve. The locking nut can position the protective plate on the positioning sleeve during use, thereby increasing the installation stability of the protective plate.

[0009] Preferably, one side of the protective plate is set in an inclined state, and the inclination angle of one side of the protective plate is 30-50 degrees.

[0010] Preferably, buffer strips are fixedly installed on both sides of the bottom of the protective plate. The lower surface of the buffer strip has a groove, and a buffer plate is slidably connected inside the groove. A rubber strip is fixedly installed on the bottom of the buffer plate. The lower surface of the rubber strip has anti-slip texture. The rubber strip facilitates contact with one side of the protective plate during use, thereby increasing the installation stability of the protective plate.

[0011] Preferably, an arc-shaped spring sheet is fixedly installed on the inner top wall of the groove on the buffer strip. The bottom of the arc-shaped spring sheet is fixedly connected to the top of the buffer plate. With the buffer strip and buffer plate set up, the arc-shaped spring sheet squeezes the rubber strip on the buffer plate during use, thereby maintaining the compression fit of the components and facilitating the installation operation, thus improving the ease of use of the mechanism.

One side of the anti-slip ring 6 is in contact with one side of the locking nut 5, and the other side of the anti-slip ring 6 is in contact with one side of the protective plate 1. The protective plate 1, positioning sleeve 2, and locking nut 5 work together to protect the components. After protection, the wear of the archway is reduced, ensuring the reliability of the rolling mill archway frame and fundamentally solving the problem of continued wear of the rolling mill archway.

The lower surface of the buffer strip 7 has a groove, and the buffer plate 8 is slidably connected inside the groove. The bottom of the buffer plate 8 is fixedly installed with a rubber strip 9. The lower surface of the rubber strip 9 has anti-slip texture. The rubber strip 9 is designed to facilitate contact with one side of the protective plate 1 during use, thereby increasing the installation stability of the protective plate 1. The inner top wall of the groove on the buffer strip 7 is fixedly installed with an arc-shaped spring sheet 10. The bottom of the arc-shaped spring sheet 10 is fixedly connected to the top of the buffer plate 8. With the buffer strip 7 and the buffer plate 8 set up, the arc-shaped spring sheet 10 squeezes the rubber strip 9 on the buffer plate 8 during use, thereby maintaining the compression fit of the components and facilitating installation operations, thus improving the ease of use of the mechanism.

[0024] Working principle: During use, the protective plate 1, positioning sleeve 2, and locking nut 5 work together to protect the components. After protection, the wear of the archway is reduced, ensuring the reliability of the rolling mill archway frame and fundamentally solving the problem of continued wear of the rolling mill archway. At the same time, it avoids damage to the archway by high-pressure water, which could cause the archway to fail in rigidity, thus ensuring the safety and stability of the equipment. The buffer strip 7 and buffer plate 8 are set up. During use, the arc-shaped spring sheet 10 squeezes the rubber strip 9 on the buffer plate 8, thereby maintaining the compression fit of the components and facilitating installation and operation, thus improving the ease of use of the mechanism.
