Cold Rolled Ribbed Steel Bar Making Machine - High Ductility Rebar Cold Rolling Mill Line
High-Ductility Cold Rolled Ribbed Steel Bar (CRB550/CRB600H) Production Line
Advanced industrial cold rolling mill line designed for manufacturing high-ductility cold-rolled ribbed rebar from plain Q235/Q195 wire rods. Integrates descaling, two-stand cold reduction, tungsten carbide crescent ribbing rollers, medium-frequency induction stress-relieving tempering, and automated flying shear cutting into one automated high-strength steel plant.

Core Design & Operational Advantages
- High-Rigidity Rolling Cassettes: Heavy cast steel housings maintain precise roller gaps under extreme rolling forces.
- Hardened Alloy Ribbing Rolls: High-purity tungsten carbide roll rings deliver over 3,000 tons of ribbed rebar output per roll regrind.
- Integrated Online Tempering: Closed-loop infrared pyrometer monitors tempering temperature (350-450°C) for consistent ductility.




Buyer Inquiries & Technical FAQ
