The wire rod rolling mill line is a critical component in modern metal processing, enabling the mass production of high-quality wire rods used in construction, automotive, and manufacturing industries. This article delves into the operational principles, technological advancements, and key parameters of these systems, with insights from HANI TECH’s rolling mill expertise.
1. Introduction to Wire Rod Rolling Mill Lines
A wire rod rolling mill line transforms billets into wire rods through a series of precision rolling processes. These lines typically consist of:
- Reheating furnaces
- Roughing, intermediate, and finishing mills
- Laying head and cooling beds
- Coiling and packaging systems
Modern lines, such as those offered by HANI TECH, achieve rolling speeds of up to 120 m/s with tolerances as tight as ±0.1 mm.
2. Key Technical Parameters
The performance of a wire rod rolling mill line depends on multiple factors. Below is a detailed table of critical parameters:
| Parameter | Typical Range | Advanced Systems (e.g., HANI TECH) |
|---|---|---|
| Input billet size | 120–160 mm² | Up to 200 mm² |
| Output diameter | 5.5–20 mm | 4.5–32 mm |
| Rolling speed | 60–90 m/s | Up to 120 m/s |
| Annual capacity | 300,000–600,000 tons | 1,000,000+ tons |
| Temperature control | ±20°C | ±5°C |
| Mill stand configuration | 10–18 stands | Up to 28 stands |
| Power consumption | 120–150 kWh/ton | 90–110 kWh/ton |
