Le 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, automobile, 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
UN wire rod rolling mill line transforms billets into wire rods through a series of precision rolling processes. These lines typically consist of:
- Fours de réchauffage
- 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.
