Product Introduction

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.

Two-Stand Cold Rolling Mill
High-rigidity reduction rolling mill reduces wire diameter while increasing tensile yield strength from 235 MPa to >550 MPa.
Tungsten Carbide Ribbing Dies
Precision CNC-engraved 3-crescent rib rolls form uniform ribs compliant with GB13788-2017 and ASTM A1064 standards.
Medium-Frequency Tempering
In-line induction heat treatment restores elongation (Agt ≥ 5.0%), producing high-ductility CRB600H rebar.
High-Efficiency Flying Shear
Continuous tracking hydraulic flying shear cuts ribbed rebar to exact lengths at speeds up to 12 m/s.

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

Q: How does this machine achieve CRB600H high ductility standards?
A: By combining controlled micro-reduction passes with in-line medium-frequency induction stress-relief tempering, we achieve Agt ≥ 5.0% and high tensile yield.
Q: Can this line produce ribbed rebar in both straight bars and coiled wire?
A: Yes, our line includes both an automatic high-speed flying shear cutting rack and a dual-spool heavy rebar take-up coiler.
