Heavy-Duty Three-Roller Cogging Mill | Roughing Mill for Rebar, Bar & Wire Rod

Our heavy-duty three-roller cogging mill is specially engineered for primary roughing passes on steel bar, wire rod, round bar, and rebar hot rolling production lines. Designed to process continuous casting billets with ultra-high reduction rates, this industrial cogging mill delivers reliable rolling performance and outstanding dimensional stability for intermediate steel blanks. We provide fully customized rolling pass designs to match your exact product mix and rolling process requirements, ensuring flexible and efficient multi-product production. Multi-product rolling capability This versatile three-roller roughing mill supports the production of steel bar, wire rod, round bar, and deformed rebar. A single cogging mill covers multiple final steel products, greatly improving production flexibility and reducing equipment investment for your rolling plant. Stable Y-type three-roll configuration Adopting a professional three-roll Y-configuration rolling structure, the mill ensures extremely stable roughing rolling with minimal vibration. It features simple and convenient pass adjustment, lowering operational difficulty and improving rolling consistency for long-term mass production. Super heavy reduction capacity Built for high-efficiency billet breakdown rolling, the three-roller cogging mill achieves a total rolling reduction of up to 90% for continuous casting billets. Large single-pass deformation effectively reduces roughing pass times and improves overall production line throughput. Custom rolling pass design for diverse steel profiles We tailor professional rolling pass systems for various raw materials and finished products, including round steel, ribbed rebar, square billets, and wire rod feedstock. Each pass design is optimized to guarantee precise blank size and uniform metal flow before finishing rolling. Durable cast steel roll for harsh rolling conditions Equipped with high-strength cast steel work rolls, the cogging roughing mill withstands high temperature, heavy load, and abrasive working conditions. The premium roll material extends equipment service life, reduces frequent replacement downtime, and cuts your operational and maintenance costs. User-friendly hydraulic roll gap adjustment Featured with simple and precise hydraulic roll gap adjustment system, the mill allows quick size calibration and routine maintenance. It is fully suitable for local maintenance teams, requiring no complex technical operation and maximizing production uptime.
