Cold Rolling Steel Mill Automatic Production Line

It is used for cold rolling round steel coils into finished rebar and round smooth steel products, improving production efficiency and product quality for construction and steel-processing applications.

Key specs include type: cold rolling mill; voltage: 380V (customizable); power: 75 kW; machine weight: 5000 kg; original coil diameter: 6–12 mm; finished rebar diameter: 5–11 mm; rolling speed: 90–120 m/min; control: full frequency conversion (VFD).

The line features automatic operation with minimal manual intervention; typical operation requires 1–2 skilled personnel for monitoring, feeding, and occasional adjustments.

Full frequency conversion refers to using a variable frequency drive (VFD) to control motor speed and torque, enabling precise rolling speed control, smooth starts/stops, and improved energy efficiency.

Lubrication is done via a brushed powder system to reduce friction during cold rolling. Phosphorus removal (surface cleaning) is performed mechanically using a CR steel wheel to improve surface quality before/after rolling.

Designed primarily for original coiled round steel (smooth coils) with diameters of 6–12 mm. Recycling of preprocessed old steel is possible but may require prior cleaning/straightening or supplier consultation.

Rolling speed ranges from 90–120 m/min. Actual throughput depends on feed diameter, finished diameter, coil length and downtime; contact the manufacturer with your input specs for a precise capacity estimate.

Yes. Standard voltage is 380V, but the production line can be customized to match local power standards—confirm required voltage when requesting a quote.

Perform daily visual checks, lubrication and cleaning; weekly checks of rollers, bearings and belts; monthly inspection of electrical cabinets, VFD settings and safety devices; replace wear parts (rollers, bearings, brushes) as needed. Follow the supplier’s maintenance schedule for best results.

Essential safety features include emergency stop buttons, guards and covers on moving parts, interlocks, clear operator controls, grounding and overload protection, and mandatory PPE for operators (gloves, eye protection, hearing protection).

Common wear parts include rolling rollers/dies, bearings, brushes, CR steel wheel, belts, and seals. Manufacturers or distributors typically supply spare parts; specify part numbers or machine model when ordering.

Packaging and shipping depend on order size and destination. The product listing cites a single-package placeholder; actual packaging will be heavy-duty crating and/or containerized shipping. Confirm packaging details, dimensions and gross weight with the supplier prior to shipment.

Yes. Finished diameter range, tooling, control options and other features can often be customized. Discuss your product requirements with the manufacturer to determine feasible customizations and tooling changes.

Support typically includes installation assistance, operator training and after-sales technical service. Warranty terms vary by supplier—confirm warranty length, scope and available service contracts when ordering.

Request a quote from the supplier and provide: required finished diameters and tolerances, input coil specs (diameter, material grade, length), desired rolling speed/capacity, local voltage and site conditions, and any customization or automation preferences. The supplier will then provide pricing, lead time and delivery options.
