PC steel wire production line process and equipment analysis
PC steel wire production lines are evolving toward high efficiency, environmental friendliness, and intelligence. Key breakthroughs include:
👉 Surface treatment using mechanical shelling achieves near-zero acid consumption;
👉 Heat treatment using medium-frequency induction power supplies for precise temperature control;
👉 Tensioning systems using dual traction ensure stability.
Future competition will focus on production line flexibility (such as multi-spec switching) and lifecycle energy savings. We recommend focusing on the integration of induction heating power supply iterations (such as all-solid-state IGBTs) and waste heat recovery technologies.
1. Core process links of the production line
1.Surface Pretreatment
Mechanical stripping replaces traditional pickling: Three sets of 120-degree stripping wheels repeatedly bend the wire rod, removing 85%-90% of the oxide scale. Remaining rust is then removed through electrolytic pickling. Compared to traditional large-tank pickling, this technology saves 27,000 tons of water, 6,900 tons of steam, and 250 tons of acid per 30,000 tons of wire per year, while also reducing the discharge of acid-containing wastewater.
Phosphating and Coating: A medium-temperature phosphating tank is used to generate the phosphate film online. An air blowing system (air volume of 210 m³/h) reduces residual liquid and enhances lubricity during subsequent drawing.
2.Drawing Forming
The straight-line wire drawing machine utilizes variable frequency control to achieve high-precision tension adjustment. It is suitable for wire rods ranging from 10 to 13 mm in diameter, with a drawing speed of up to 200 m/min. Its advantage lies in its adaptability to a variety of high-carbon steel products, including steel cord, welding wire, and PC wire.
3.Heat Treatment (Quenching and Tempering)
Quenching + Tempering Dual Process: The typical process involves medium-frequency induction quenching at 900°C (500kW IGBT power supply) and tempering at 450°C, with a line speed of 100-110 m/min. After quenching, the wire is water-cooled and blown dry, followed by secondary cooling for final shaping. Power consumption is approximately 400 kWh/ton.
Energy-saving improvements: For example, the lead pot tempering process has been optimized, increasing the number of steel wires per pot from two to four, doubling efficiency and reducing energy consumption by 20%.
4.Finishing and Collection
Cutting to length (hydraulic shears), chamfering and rolling (positioning accuracy ±0.5mm), and automatic wire separation and winding (spools/horizontal collection baskets) enable continuous production.
