Cold Rolling Rebar Machine
Products Description
2 rib cold rolling rebar machine
A 2‑rib cold rolling rebar machine (two‑rib cold‑rolled ribbed rebar mill) is specialized equipment for cold‑rolling hot‑rolled wire rod into rebars with two parallel transverse ribs on the surface, mainly used in construction for reinforced concrete, featuring high efficiency, material saving, and stable mechanical properties. Below is a detailed breakdown:
Products Core Definition & Advantages
Core Function: Cold‑rolls Φ6.5–14 mm hot‑rolled wire rod into Φ5–13 mm two‑rib deformed bars, enhancing yield/tensile strength (up to CRB550/600H) while ensuring clear, full ribs for strong concrete bonding.
Key Advantages:
Saves ~15%–20% material vs. plain round bars; improves bond strength by 30%+.
High production speed (120–300 m/min for standard models, up to 600 m/min for high‑speed lines) and low energy consumption vs. hot rolling.
PLC + servo + frequency conversion control enables precise diameter/rib size and automatic cutting.
Process Flow
- Wire rod pay‑off → surface derusting (shot blasting/chemical cleaning) → scale breaking
- Cold rolling (two‑rib forming + diameter reduction via grooved rolls)
- Induction tempering (to improve ductility and eliminate residual stress)
- Straightening + servo flying shearing (cut to 1–12 m lengths)
- Coil taking‑up/stacking → bundling → packaging
