Rolling Production Line Supplier

Rolling Production Line

The rolling production line is engineered for variable cross-section rolling of automotive leaf springs and control arms, combining precision induction heating with a rolling unit to form spring steel billets into a profile with progressively varying thickness along the length — meeting the engineering requirements of lightweight design and optimized stress distribution in leaf spring applications.
The core heating unit employs medium-frequency induction technology with no preheating required — ready to operate immediately. It delivers fast ramp-up speed, uniform through-heating, minimal scale formation, and reduced decarburization, resulting in superior surface quality. A real-time scanning and closed-loop control system continuously monitors discharge temperature, preventing overheating and maintaining high process accuracy.
The induction heating equipment interfaces directly with the rolling unit's control signals, enabling fully synchronized process parameter coordination. Heating and rolling cycle times are precisely matched to minimize heat loss and ensure workpieces undergo forming within the optimal temperature window, guaranteeing dimensional accuracy of the cross-section profile and uniformity of the resulting microstructure.
The line features a compact footprint, low thermal radiation, and zero fume emissions — delivering a clean and comfortable working environment. High automation with minimal manual intervention supports continuous, high-volume production of multiple leaf spring and control arm specifications, with straightforward changeover between product types.
Compared to conventional gas or resistance furnace heating, the induction-based approach delivers significant energy savings and high thermal efficiency, offering a clear competitive advantage in overall operating cost and aligning with the principles of modern green manufacturing.
