Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment, and in particular to a sliding guide with a dust removal function. Background Art

[0002] Dust and scale pollution problems in steel mills are primarily caused by the powdered scale generated by the cooling and deformation of the rolled piece, which adheres to the red steel. As the rolled piece vibrates and deforms, it escapes from the rolled piece and becomes the primary source of dust pollution on the rolling line. Guides, essential auxiliary equipment for wire rod rolling mills, have long been used in my country using designs from the late 20th century and early 2000s. Major domestic metallurgical equipment manufacturers have not made major modifications, and they have been used solely for guiding purposes. Some steel mills have added dust removal devices between mill stands, which have been moderately effective but significantly increase investment costs and impose a significant burden on subsequent maintenance. Furthermore, rolling line accidents can easily cause devastating damage to the dust removal devices. Summary of the Invention

[0003] The present invention provides a sliding guide with a built-in dust removal function to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a sliding guide with a built-in dust removal function, comprising a guide pipe body;

[0005] A first through hole is provided at one end of the outer side of the guide tube body, the first through hole is set at 45°, and the first through hole is arranged around the outer side of the guide tube body. A dust removal ring is provided on the outer side of the guide tube body, and the dust removal ring is sleeved on the outer side of the first through hole. The dust removal ring is fixedly connected to the guide tube body, and a fixing sleeve is provided on the outer side of the guide tube body. The top of the fixing sleeve is a wedge-shaped structure, and a guide base is sleeved on the outer side of the fixing sleeve.

[0006] A further improvement to the present invention's technical solution is that a water inlet pipe and an exhaust pipe are symmetrically arranged outside the dust removal ring, and each pipe passes through the dust removal ring and is arranged inside the ring. With this technical solution, the water inlet pipe and exhaust pipe can be activated simultaneously to achieve water spray dust removal and drainage or exhaust dust removal operations on the rolled product.

[0007] A further improvement of the technical solution of the present invention is that an adjustment ring is provided inside the dust removal ring, the adjustment ring is embedded in the dust removal ring, and the adjustment ring is rotatably connected to the dust removal ring. With the above technical solution, the adjustment ring in this solution can be rotated, thereby facilitating adjustment.

[0008] A further improvement to the present invention's technical solution is that two adjacent annular grooves are provided on the outer side of the adjustment ring, the grooves being arranged parallel to each other and interconnected with the water inlet pipe and the exhaust pipe, respectively. Using this technical solution, the annular grooves can be connected to the water inlet pipe and the exhaust pipe, respectively, forming two independent dust removal systems that assist each other in dust removal operations.

[0009] A further improvement to the technical solution of the present invention is that: a second through hole is provided on the inner side of the adjustment ring, and there are two second through holes, which are symmetrically arranged on the inner walls of both sides of the adjustment ring. The two second through holes are respectively connected to the two annular grooves, and the second through holes are arranged at 45 degrees. The second through holes are arranged perpendicular to the first through holes. Using the above technical solution, the second through holes in this solution are respectively connected to the two annular grooves, realizing the operation of spraying water while sucking air. At the same time, the inclined second through hole drives the adjustment ring while guiding the water flow from the annular groove to the center of the first through hole. The second through hole is at a 45 degree angle to the axial and radial directions of the adjustment ring, thereby conveniently providing a driving force for the rotation direction of the adjustment ring while obliquely guiding the water flow.

[0010] A further improvement of the technical solution of the present invention is that sealing plates are provided on both sides of the dust removal ring and in the middle of the dust removal ring, and the sealing plates are arranged on the outside of the adjustment ring and in the middle of the adjustment ring.

[0011] A further improvement of the technical solution of the present invention is that: a keyway and a connecting block are respectively provided on the bottom of the guide base and the rolling mill mounting beam, the positions of the keyway and the connecting block correspond to each other, and the structures of the keyway and the connecting block correspond to each other.

[0012] A further improvement of the technical solution of the present invention is that a fastening bolt is provided at the top of the guide base, the fastening bolt passes through the guide base and is arranged inside the guide base, and the bottom end of the fastening bolt is arranged in the middle of the wedge-shaped structure at the top of the fixing sleeve.

[0013] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0014] 1. The present invention provides a sliding guide with a built-in dust removal function. The dust removal ring is provided to spray water in the circumferential direction of the rolled piece to remove dust and scale. There is no need to add a separate dust removal water system. The purpose of dust removal and scale removal can be achieved by directly connecting to the cooling water of the rolling mill. At the same time, the circumferential water spray holes of the guide pipe form a certain reverse angle with the running direction of the rolled piece, which maximizes the dust removal and scale removal effect.

[0015] 2. The present invention provides a sliding guide with a built-in dust removal function. The guide tube is integral and more reliable and durable than a split and combined guide. The guide tube is water-cooled to reduce wear and increase service life.

[0016] 3. The present invention provides a sliding guide with a built-in dust removal function. The guide tube is installed on the guide base as a whole and is tightened by a screw. The pressing surface of the tube fixing sleeve has a wedge-shaped inclined surface, which is opposite to the movement direction of the rolled piece. During the rolling process, the wedge-shaped effect ensures that the guide will not loosen or exit, making the operation more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

The pressurized cooling water entering the dust removal ring 3 flows into the annular groove 304, and when the second through hole 305 is aligned with the first through hole 2, the water is sprayed into the first through hole 2. The second through hole 305 forms a reaction force after spraying the water out of the second through hole 305, and drives the adjusting ring 303 to rotate through the component of the reaction force. The sprayed water flow is then switched between different first through holes 2, and is sprayed on the circumferential surface of the rolled piece through the first through hole 2 with an angle opposite to the running direction of the rolled piece, wrapping up the rolling deformation dust in the early stage of escaping, so that the dust can be minimized.
