Description

Technical Field

[0001] This invention relates to the field of steel wire production technology, and in particular to a steel wire production process. Background Technology

[0002] In modern industrial production, steel wire, as an important basic material, is widely used in various fields such as construction, machinery manufacturing, and transportation. With the increasing demands for steel wire quality across industries, optimizing steel wire production processes and improving its performance and quality has become a key focus of industry attention. Currently, the raw material pretreatment process in steel wire production has certain shortcomings. Traditional dust removal and shot blasting methods are inefficient and fail to thoroughly remove impurities and rust from the raw material surface, affecting subsequent surface treatment and potentially causing quality problems during use. In terms of surface treatment, the processing techniques for ordinary and bright steel wire are not refined enough to fully meet the requirements of different applications regarding lubricity, rust prevention, and surface gloss. Furthermore, the connection between multiple processes in the forming and subsequent processing stages is not smooth enough, and operations such as stabilization heat treatment, washing, and drying are ineffective, making it difficult to guarantee the quality stability of the finished steel wire. Furthermore, existing shot blasting equipment used in steel wire production has many shortcomings. Inadequate structural design leads to low shot recycling efficiency, increasing production costs; uneven shot blasting results affect the surface quality of the steel wire; and inconvenient equipment installation and maintenance reduce production efficiency. These problems severely restrict the development of the steel wire production industry, necessitating a process and supporting equipment that is structurally simple, low-cost, easy to install, and effectively improves the quality of steel wire production.

Phosphating the raw materials with phosphating solution to enhance lubricity and rust prevention; b. If producing bright steel wire, the phosphated raw materials are immersed in a boronizing bath containing trisodium phosphate and borax. C. Molding and subsequent processing a. The processed raw materials are continuously drawn into steel wire through multiple passes. b. If producing bright steel wire, the semi-finished wire after drawing is stress-annealed in a bright annealing furnace, while hydrogen is introduced for protection. c. If coated steel wire is required, the semi-finished wire after drawing will be coated with zinc, aluminum alloy or other coatings. d. Perform a second stabilization heat treatment on the coated steel wire or bright steel wire; e. The steel wire is washed and dried to thoroughly remove any residual substances and moisture from the surface, ensuring that the surface is clean and dry; f.

[0033] like Figure 8 As shown, the specific structure of the filter storage structure 43 includes a storage cavity 431, a filter plate 432, a collection box 433, and a conveying groove 434.

A conveying groove 434 is provided on the lower left side of the storage cavity 431, and the lower side of the conveying groove 434 is connected to the inlet of the rotary polishing mechanism 2. The upper opening of the collection box 433 is located below the filter plate 432, and the collection box 433 is laterally movably connected to the lower interior of the storage cavity 431.

[0034] The invention is used as follows: It features a simple and reasonable structure, low production cost, and convenient installation. During use, raw materials enter the shot blasting device. The conveying mechanism 5 moves the raw materials inside the outer shell 1. Inside the outer shell 1, the electrostatic dust removal module 3 first performs preliminary dust removal on the raw materials, removing most of the surface dust. Subsequently, the raw materials enter the rotary shot blasting mechanism 2 for shot blasting. When the rotary shot blasting mechanism 2 is working, the motor 234 starts, driving the drive pulley 233 to rotate. Power is transmitted to the driven pulley 231 via the belt 232, causing the rotating seat 21 to rotate on the right side inside the center of the outer shell 1. In the shot blasting mechanism 22, the shot enters through the inlet pipe 2210. The shot enters the buffer chamber 229, then through the shot conveying hole 228 into the shot feeding groove 224, and through the shot feeding hole 223 into the shot blasting chamber 221. Simultaneously, high-pressure gas enters the annular chamber 226 through the high-pressure gas hole 227, and through the annular opening 225 into the shot blasting hole 222. After mixing with the shot, it is ejected at high speed from the shot blasting hole 222 to blast the raw material, removing surface impurities and rust. The baffle 2212 acts as a barrier and guide, ensuring the shot is effectively recovered and falls. The blasted shot and impurities fall into the recovery chamber 41, completing the recovery work of the circulating filtration mechanism 4. In the circulating filtration mechanism 4, the lifting mechanism 42 starts operating, and the motor 424 drives the lifting mechanism. The screw rod 422 rotates within the lifting pipe 421, conveying the shot and impurities in the recovery chamber 41 through the discharge port 423 to the storage chamber 431 of the filter storage structure 43. In the storage chamber 431, the shot and impurities fall onto the inclined filter plate 432. The impurities fall through the filter plate 432 into the collection box 433, while the shot remains in the storage chamber 431 and returns to the rotary polishing mechanism 2 via the conveying trough 434, achieving shot recycling. After raw material pretreatment, the surface treatment step begins. If producing ordinary steel wire, the raw material is directly phosphated with phosphate solution to enhance its lubricity and rust resistance; if producing bright steel wire, the phosphated raw material needs to be further phosphated. The raw materials are immersed in a borosilicate bath containing trisodium phosphate and borax for immersion treatment. Following this, shaping and subsequent processing steps are performed. The treated raw materials are continuously drawn in multiple passes to obtain steel wire. If producing bright steel wire, the semi-finished wire after drawing needs to be stress-annealed in a bright annealing furnace while being protected with hydrogen gas. If producing coated steel wire, the semi-finished wire after drawing is coated with zinc-aluminum alloy or other coatings. Afterward, the coated or bright steel wire undergoes another stabilization heat treatment, followed by washing and drying to thoroughly remove surface residues and moisture, ensuring a clean and dry surface. Finally, the finished steel wire is coated with anti-rust oil and packaged for easy storage and transportation.
