Description

Technical Field

[0001] The present invention relates to the technical field of wire production, and specifically provides a method for recycling the head and tail scrap steel of wire flying shears. Background Technique

[0002] During the wire production process, after the flying shear cuts the head and tail of the wire, the collection of the generated scrap steel has always been a difficult problem in the industry. The traditional recycling method is relatively crude. There is no effective guiding device at the flying shear outlet, and the scrap steel often scatters everywhere, resulting in low collection efficiency, only reaching about 60% - 70%. Moreover, during the collection process, due to the lack of buffering and classification measures, the scrap steel collides and rubs against each other, and about 20% - 30% of the scrap steel will be deformed and worn to varying degrees, which greatly reduces the secondary utilization value of the scrap steel. At the same time, manual operation accounts for a relatively large proportion in the entire recycling process. From collection, sorting to transportation and storage, the labor cost per ton of scrap steel is as high as 80 - 100 yuan, which not only increases the production cost, but also due to the instability and inefficiency of manual operation, it is difficult to ensure the quality and efficiency of scrap steel recycling, and cannot meet the requirements of modern wire production enterprises for resource recycling and cost control. Summary of the Invention

[0003] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a method for recycling the head and tail scrap steel of wire flying shears, which has the advantages of significantly improving the recycling efficiency, etc., and solves the problems such as the scrap steel often scatters everywhere and the collection efficiency is low.

[0004] (II) Technical Solutions To achieve the above-mentioned purpose of significantly improving the recycling efficiency, the present invention provides the following technical solutions: A method for recycling the head and tail scrap steel of wire flying shears, including S1 equipment transformation and installation, S2 collection and sorting process optimization, and S3 transportation and storage link improvement. The S1 equipment transformation and installation includes upgrading the flying shear outlet guiding device and setting up a buffer collection chute; Among them, the S2 collection and sorting process optimization includes automatic collection container switching and setting the frequency of scrap steel sorting; Among them, the S3 transportation and storage link improvement includes customizing short-distance transportation vehicles and planning classified storage areas.

[0005] Preferably, the upgrade of the flying shear outlet guiding device: Install a high-precision pneumatic guiding plate at the flying shear outlet. The opening and closing angle of the guiding plate can be accurately adjusted between 20° and 70°, and the adjustment accuracy is ±2°. Its material is selected as high-strength wear-resistant alloy steel with a hardness of HRC50 - 55, ensuring that it can withstand the frequent impact of scrap steel without being easily deformed, guiding the scrap steel to a predetermined collection area, and controlling the landing deviation of the scrap steel within ±10 cm, reducing scattering.

[0006] Preferably, the buffer collection chute is arranged as follows: a buffer collection chute with a length of 3 meters is installed under the guiding plate. The inner lining of the chute is a 5-mm-thick rubber buffer layer to reduce the collision damage during the sliding of scrap steel. The inclination angle of the chute is 10°, ensuring that the scrap steel can quickly slide down to the collection container by gravity. The designed capacity of the chute is 0.5 tons of scrap steel per batch to prevent accumulation and blockage.

[0007] Preferably, for the automatic collection container switching: two collection boxes with a volume of 1 cubic meter are equipped. When the scrap steel in one collection box reaches 0.8 cubic meters, it is automatically switched to another empty box within 1 minute through the electric rail system to ensure that the flying shear operation is not affected. The collection box adopts a double-layer structure, with the inner layer made of stainless steel and the outer layer reinforced with carbon steel to prevent scraping and corrosion of the scrap steel and extend its service life.

[0008] Preferably, for the setting of the frequency of scrap steel sorting: after each collection box is filled with scrap steel, a sorting operation is carried out. The hydraulic sorting fork is used to roughly classify the scrap steel according to length and thickness. The sorting time is controlled within 10 minutes to make the scrap steel easier to process in subsequent processing and improve the recycling efficiency. After sorting, the proportion of scrap steel meeting the direct melting standard is increased to more than 80%.

[0009] Preferably, for the customization of the short-distance transport vehicle: a small electric flatbed truck is used to transport the scrap steel to the storage area. The vehicle load capacity is 1.5 tons. The bottom of the carriage is laid with an anti-slip rubber mat, and removable guardrails with a height of 1 meter are installed around to ensure that the scrap steel does not scatter during transportation. The transportation speed is 10 kilometers per hour, and the single transportation time does not exceed 15 minutes.

[0010] Preferably, for the planning of the classified storage area: in the storage area, storage areas for different specifications of scrap steel are divided. Each area has an area of 10 square meters and is distinguished by obvious signs. The ground is hardened and laid with a moisture-proof mat to prevent the scrap steel from rusting. The storage height does not exceed 1.5 meters for easy access and inventory. The stored scrap steel is randomly inspected regularly to ensure the stable quality of the scrap steel, and the rust rate is controlled below 5%.

[0011] (III) Beneficial effects Compared with the prior art, the present invention provides a method for recycling the head and tail scrap steel of wire rod flying shear, having the following beneficial effects: 1. For the method for recycling the head and tail scrap steel of wire rod flying shear, this method significantly improves the recycling efficiency: through the setting of the high-precision pneumatic guiding plate and the buffer collection chute, the landing point of the scrap steel is accurate, and the scattering situation is greatly improved. The automatic switching mechanism of the collection box ensures the continuous progress of the flying shear operation, increasing the overall recycling efficiency from the original 60% - 70% to more than 90%, effectively reducing the accumulation and waste of scrap steel at the production site and improving the resource utilization rate.

[0012] 2. The method for recycling the head and tail scrap steel of the wire rod flying shear improves the quality of the scrap steel: the optimization of the buffer collection chute and the sorting link greatly reduces the collision deformation and wear of the scrap steel during the recycling process. The proportion of scrap steel meeting the direct remelting standard has increased from 50% - 60% previously to over 80%, providing higher-quality raw materials for subsequent remelting and smelting, reducing the energy consumption and impurity content during the steelmaking process, and contributing to improving the quality of steel products.

[0013] 3. The method for recycling the head and tail scrap steel of the wire rod flying shear reduces the labor cost: the introduction of automated equipment and the optimization of the process reduce the manual intervention links, such as the automatic collection box switching and the transportation by electric flatbed truck. The labor cost per ton of scrap steel recycling has been significantly reduced from 80 - 100 yuan to 30 - 40 yuan. While improving the production efficiency, it reduces the operation cost of the enterprise and enhances the competitiveness of the enterprise in the market.

[0014] 4. The method for recycling the head and tail scrap steel of the wire rod flying shear optimizes the storage management: the planning of the classified storage area and the moisture-proof and rust-proof measures ensure the quality stability of the scrap steel during storage. The rusting rate is controlled below 5%, facilitating the enterprise to manage and allocate the scrap steel resources in an orderly manner, reducing the losses caused by improper storage, and providing strong support for the sustainable development of the enterprise.
