It is a 4-high cold re-rolling mill engineered to produce high-quality rebars and steel wire rods. The machine is designed for efficiency, durability and continuous operation in steel processing and recycling applications.
4hi (4-high) refers to a roll configuration with two smaller working rolls and two larger backup rolls. This design improves strip flatness, rigidity and roll life compared with 2-high mills, making it well suited for precision cold rolling of rebars and wire rod billets.
The mill is built for cold re-rolling of steel billets into rebars and steel wire rods. It can also be used for reprocessing and recycling various carbon steel feedstock used in construction, fabrication and engineering.
Core components include PLC control, engine, bearings, gearbox, motor, pressure vessel, gears and pump. Voltage options listed are 660V or 380V. Weight is approximately 5000 kg; power ratings and exact dimensions depend on the chosen mill configuration.
Power, overall dimensions and production capacity depend on configuration, rolling schedule and final product specifications. Please provide required final sizes, throughput and material details so we can supply exact ratings and a capacity estimate.
Yes. Dimensions, roll specifications, gearbox ratios, motor power, automation level and auxiliary equipment can be customized to match your production targets and material requirements.
Yes. A machinery test report is provided and video outgoing inspection is included to document machine condition and functional tests prior to shipment.
Installation and commissioning support, as well as operator and maintenance training, are available. These services can be provided on-site or remotely depending on location and customer preference.
We supply spare parts, technical support and troubleshooting assistance. Long-term service contracts and priority spare-part provisioning can be arranged to minimize downtime.
Typical maintenance includes daily lubrication and inspection, weekly checks of roll alignment and drive components, monthly gearbox and hydraulic system inspection, and scheduled major overhauls based on operating hours. A detailed maintenance schedule is provided with the machine.
Standard safety provisions include emergency stops, guarding for moving parts, interlocks for access panels and PLC-based fault monitoring. Operators should use appropriate PPE such as gloves, eye protection, hearing protection and steel-toe footwear.
Warranty terms and coverage details vary by order and can be provided with your quotation. The machine is tested prior to shipment and comes with documentation of acceptance tests; extended warranties are available upon request.
Lead time depends on configuration, customization and order size. Shipping is arranged per customer preference with standard export packaging; detailed delivery time and logistics are provided in the formal offer after configuration is confirmed.
Contact sales with your required final product sizes, desired throughput (tons/hour or tons/day), feed material specification and any customization requests. We will prepare a tailored technical proposal and competitive quotation.
Utilities vary by configuration but typically include the specified electrical supply (380V or 660V), hydraulic or pneumatic supply if applicable, lubrication systems and standard plant services. Exact utility requirements are provided with the machine technical datasheet.
