Description

Technical Field

[0001] This utility model relates to the field of iron oxide scale removal equipment, and in particular to a roughing mill equipped with iron oxide scale removal equipment. Background Technology

[0002] A roughing mill is an intermediate billet used in steel rolling production to initially roll steel billets into a certain thickness and shape. Before rolling, it is necessary to remove the iron oxide scale from the billet surface. If the iron oxide scale is not removed before rolling, it will be pressed into the strip surface by the rolls during the rolling process, affecting the surface quality of the strip and causing defects such as pitting and dents. Furthermore, residual iron oxide scale increases the friction between the rolls and the billet, accelerating roll wear, reducing roll life, and increasing production costs. Common iron oxide scale removal equipment uses a high-pressure water descaling system. A high-pressure water pump pressurizes water to a certain level, forming a powerful fan-shaped water jet through descaling nozzles. This jet is sprayed onto the billet surface, cutting and rapidly cooling the iron oxide scale, causing it to peel off from the base material and be washed away. However, this method of iron oxide scale removal is wasteful of water resources and not conducive to energy conservation and emission reduction. Therefore, this invention proposes a roughing mill with an iron oxide scale removal device. Utility Model Content

[0023] like Figure 1-5 As shown, a roughing mill with an iron oxide scale removal device includes a conveying roller 1 located in front of the roughing mill unit 14, a bottom cleaning device 3 installed below the conveying roller 1, and a top cleaning device installed above the conveying roller 1.

[0024] The top cleaning device includes brackets 4 symmetrically mounted above the conveyor rollers 1. A mounting frame 6 is mounted between the tops of the brackets 4 via a horizontal moving mechanism 5. A second mounting frame 8 is mounted on the first mounting frame 6 via a vertical moving mechanism 7. A grinding motor 9 is mounted on the second mounting frame 8. The output end of the grinding motor 9 is keyed to a rotating shaft 11, and the other end of the rotating shaft 11 is keyed to a grinding disc 12. A negative pressure adsorption housing 10 surrounds the grinding disc 12. Adsorption holes 1001 are formed on the sidewall of the negative pressure adsorption housing 10, and the adsorption holes 1001 are connected to a negative pressure adsorption device. The negative pressure adsorption device includes a vacuum pump. A filter screen is installed at the air inlet of the vacuum pump, and a waste collection device is installed below the sidewall of the filter screen. The negative pressure adsorption housing 10 is connected to the second mounting frame 8 via a third mounting frame 13, ensuring that it moves up and down together with the grinding disc 12.

[0025] Specifically, the cleaning process of the top cleaning equipment is as follows: According to the actual situation, the grinding disc 12 is moved to a suitable height by the vertical moving mechanism 7; then the negative pressure adsorption device and the grinding motor 9 are started, and the grinding disc 12 grinds the iron oxide scale, causing it to fall off the surface of the steel billet and be removed under the negative pressure adsorption of the negative pressure adsorption device; during the grinding process, the horizontal moving mechanism 5 changes the position of the grinding disc 12 in the horizontal position, so that the grinding is thorough and the cleaning quality is improved.

[0026] Both the aforementioned lateral movement mechanism 5 and vertical movement mechanism 7 adopt a lead screw mechanism. The lead screw is driven to rotate by a lead screw motor, and the mounting frame reciprocates along the direction of the lead screw under the limiting action of the slide rod.

[0027] A storage box 2 is installed below the bottom cleaning device 3. The bottom cleaning device 3 includes a grinding platform 305 located below the conveyor roller 1. The grinding platform 305 is mainly used to protect the mechanism below and prevent iron oxide chips from affecting the operation of the mechanism. A grinding belt 304 is symmetrically installed above the grinding platform 305 in the front-back direction. The grinding belt 304 is located in the gap between adjacent rollers and is slightly higher than the conveyor roller 1, abutting against the surface of the steel billet. The grinding belt 304 is sleeved on a number of symmetrically distributed driven wheels 303 and a driving wheel 302 that drives the grinding belt 304 to move. Among them, the number of driven wheels 303 are installed above the grinding platform 305, and the driving wheel 302 is installed below the grinding platform 305. The driving wheel 302 is connected to a drive device. The drive device is a geared motor, and a drive device housing 301 for housing the geared motor is installed at the bottom of the grinding platform 305. The grinding platform 305 has a through hole for the grinding belt 304 to pass through.

[0028] The cleaning process of the bottom cleaning device 3 is as follows: the drive device drives the drive wheel 302 to rotate, which drives the grinding belt 304 to move. During the movement of the grinding belt 304, it comes into contact with the surface of the steel billet through friction. The iron oxide waste is removed from the surface of the steel billet by means of friction and finally falls into the grinding platform 305 and the collection box 2, thereby realizing the collection of iron oxide waste.

[0029] During the above-mentioned cleaning process, the billet moves toward the roughing mill 14 under the action of the transport roller 1. During the movement, the top cleaning device and the bottom cleaning device 3 simultaneously remove the iron oxide waste from the surface of the billet. After the billet has completely passed through the top cleaning device and the bottom cleaning device 3, all the iron oxide waste on its upper and lower surfaces is completely removed, and finally it enters the roughing mill 14 for roughing.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
