[0002] Hot-rolled ribbed steel bars are the most widely used steel product in the world. They are formed from steel billets through a series of processing steps. To improve the performance of these bars, the formed steel billets need to undergo a pressing and rolling process.

[0003] Steel billets easily develop oxide scale in the air. If this scale is not removed, it can not only cause steel burn-through but may also be pressed into the billet, creating defects and affecting the surface quality of the product. Existing equipment for removing oxide scale can only treat the scale on one surface of the billet, resulting in incomplete removal of the scale from the entire billet. Utility Model Content

[0044] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0045] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0046] This embodiment provides a device for cleaning oxide scale from steel billets, used to remove oxide scale from the surface of steel billets to ensure that the steel is not burned and that the oxide scale is not forged into the interior of the steel, thereby improving product quality. Figure 1 As shown, the cleaning device mainly includes a conveying mechanism 100 and a processing mechanism 200. The conveying mechanism 100 is connected to the feed end of the processing mechanism 200. The cast square steel billet is conveyed to the processing mechanism 200 through the conveying mechanism 100. The processing mechanism 200 uses a scraper 204 to scrape off the oxide scale around the steel billet.

[0047] Figure 2 The diagram shows the structure of the conveying mechanism 100 in the cleaning device. The conveying mechanism 100 mainly consists of conveying rollers 101, roller seats 102, and guides 103. Several conveying rollers 101 are arranged in a horizontal array, and both ends of the conveying rollers 101 are rotatably connected to the roller seats 102. Support legs are formed at both ends of the bottom of the roller seats 102, and roller grooves 1021 are machined on the side of the roller seats 102 facing the conveying rollers 101. The ends of the conveying rollers 101 are installed in the roller grooves 1021.

[0048] A guide 103 is mounted on the top of the roller holder 102 for guiding the conveyed steel billet. The guide 103 is located adjacent to the processing mechanism 200. The guide 103 is rotatably connected to the roller holder 102 via a rotating shaft 1031. A flat plate is formed on the side wall of the rotating shaft and extends radially outward along the rotating shaft 1031. Figure 1 It can be seen that the flat plate of the guide 103 is in contact with the feed end of the processing mechanism 200, and the guide 103 can be rotated to any angle on the roller seat 102 via the rotating shaft 1031.

[0049] See the internal structure of the processing unit 200. Figure 3 , Figure 4 This is another perspective of the processing mechanism 200. The processing mechanism 200 mainly includes a fan 201, a retainer 202, an adjusting spring 203, a scraper 204, an adjuster 205, a sleeve 206, a slider 207, and a slide rail 208. The structure of the adjuster 205 is as follows... Figure 6As shown, the regulator body 2051 is formed by connecting two flat plates at a certain angle. A storage groove 2054 is machined into the bottom of either of the two flat plates, and the scraper 204 can be folded into the storage groove 2054. A spring groove 2055 is formed at the bottom of the storage groove 2054 for installing a torsion spring 209. A connecting hole 2052 is provided on the side wall of the regulator 205, passing through the side wall of the regulator 205 and the side wall of the storage groove 2054. A fixing shaft 2053 is formed on the side of the regulator body 2051 opposite to the storage groove 2054.

[0050] Figure 5 This is a schematic diagram of the combined structure of the regulator 205, scraper 204, and torsion spring 209. As shown in the diagram, the scraper 204 is installed in the receiving groove 2054 of the regulator 205. One end of the scraper 204 has a through hole with the same diameter as the connecting hole 2052, which extends through both side walls of the scraper 204. The scraper 204 is rotatably connected to the regulator 205 via a pin. The torsion spring 209 is installed in the spring groove 2055 on the regulator 205 and is fixedly connected to the scraper 204. Due to the elastic force of the torsion spring 209, the scraper 204 always maintains a certain angle with the receiving groove 2054.

[0051] When the steel billet slides under the scraper 204, the scraper 204 is squeezed and rotates. The torsion spring 209 is twisted and has elastic force. The torsion spring 209 applies elastic force to the scraper 204, so that the scraper 204 is in close contact with the surface of the steel billet, thereby scraping off the oxide scale on the surface of the steel billet.

[0052] The center of the processing unit 200 consists of four such Figure 5 The square cavity formed by the combined structure of the regulator 205, scraper 204, and torsion spring 209 has a flared shape on the side facing the conveying mechanism 100. The retainer 202 has a square structure, with a sleeve 2021 formed around its inner perimeter. The sleeve 2021 is hollow inside. One end of the adjusting spring 203 is installed inside the sleeve 2021, and the other end is sleeved on the fixed shaft 2053 of the regulator 205. The sleeve 206 is sleeved on the outside of the sleeve 2021 and the adjusting spring 203, with one end abutting against the surface of the regulator 205 and sliding along the axial direction on the sleeve 2021.

[0053] When the billet is large, the four adjusting pieces 205 that are pressed together will be spread apart, the adjusting spring 203 will be compressed, and the sleeve 206 will be pushed towards the retainer 202 by the adjusting pieces 205. The sleeve 206 will slide on the sleeve 2021. After the billet passes through the adjusting pieces 205, the adjusting spring 203 releases its elasticity and pushes the adjusting pieces 205 back to their initial position, causing the four adjusting pieces 205 to close again.

[0054] One side of the retainer 202 is fixedly connected to one end of the roller seat 102. A slide rail 208 is vertically mounted on the side of the retainer 202 away from the conveying mechanism 100. Two slide rails 208 are respectively installed on the left and right sides of the retainer 202, and sliders 207 are mounted on the slide rails 208 on both sides. The blower 201 has mounting ears formed on both sides, and these mounting ears extend along the width direction of the retainer 202 and are fixedly connected to the sliders 207. When scale accumulates in the regulator 205, the slider 207 is activated, causing the blower 201 to move to the position of the regulator 205. Subsequently, the blower 201 is activated to blow the scale out of the cavity from the side adjacent to the conveying mechanism 100.

[0055] Combination Figure 1 , Figure 3 as well as Figure 4 The use of the cleaning device is explained below. First, molten steel from the ladle is poured into a square billet. The billet is then conveyed to the cleaning device. The conveying mechanism 100 is activated, and the conveying roller 101 rotates to transport the billet to the processing mechanism 200. Billets that are slightly off-center to the left or right are conveyed to the front end of the processing mechanism 200 and, under the action of the guide 103, enter the cavity formed by four adjusters 205. Driven by the conveying roller 101, the billet slides through the cavity. The billet compresses the scraper 204, causing the torsion spring 209 to compress. The torsion spring 209 then releases its elasticity, pressing the scraper 204 against the surface of the billet. The scraper 204 removes the oxide scale from the edges of the billet.

[0056] When the billet is large, the four adjustable pieces 205 that are close together will be spread apart, the adjusting spring 203 will be compressed, and the sleeve 206 will be pushed towards the retainer 202 by the adjustable pieces 205. The sleeve 206 will slide on the sleeve 2021. After the billet passes through the adjustable pieces 205, the adjusting spring 203 releases its elasticity and pushes the adjustable pieces 205 back to their initial position, causing the four adjustable pieces 205 to close again. When there is a lot of oxide scale accumulated inside the cavity formed by the four adjustable pieces 205, the slider 207 installed on the retainer 202 is activated. The slider 207 slides on the slide rail 208, causing the blower 201 to move to the position of the cavity. Then the blower 201 is activated to blow the accumulated oxide scale out from one end of the adjacent conveying mechanism 100, preventing the scraper 204 from getting stuck and unable to rotate due to oxide scale blockage. The billet after the oxide scale is scraped off enters the next processing step.

[0057] A cavity is formed by splicing four regulators 205 together. A scraper 204 is installed inside the cavity. The scraper 204 is connected to the regulator 205 by a torsion spring 209, thereby scraping off the oxide scale around the steel billet.

[0058] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
