Rolls and Copper Mould Tubes play irreplaceable roles in industrial production. Rolls are core tools for metal plastic deformation, shaping billets into sheets, bars or profiles while determining rolling efficiency and product quality . Copper Mould tubes excel in heat exchange and fluid transfer—they act like “vascular systems” in HVAC for refrigerant circulation and enable thermal management in new energy fields , thanks to superior thermal conductivity. Below are concise strategies for their efficient use.

1. Efficient Utilization of Rolls

Rollers are the core component in the metallurgical rolling process. They directly determine the precision, surface quality and dimensional accuracy of steel plates, profiles and other products. Their wear resistance and stability greatly affect production efficiency and cost control, making them indispensable for high-quality metallurgical production.

The following is several correct methods for using Rolls.

Targeted Material Selection: For heavy steel rolling, use HSS or tungsten carbide rolls (2–3x more wear-resistant than cast iron) . For aluminum processing, choose copper alloy rolls for better heat dissipation and crack resistance. Ceramic-coated rolls suit precision thin-sheet production to maintain surface smoothness.

Process Optimization: Keep load below 80% of roll capacity and speed ≤3 m/s for aluminum rolling. Use uniform water sprays to stabilize roll temperature at 50–70°C, avoiding thermal deformation. Add a slight crown to balance pressure and reduce edge wear.

Proactive Maintenance: Conduct ultrasonic inspections every 200–300 hours to detect early cracks and cut unplanned downtime.

2. Efficient Utilization of Copper Mould Tubes

Copper Mould Tubes are the key component in metallurgical continuous casting. They cool molten steel into billets efficiently, directly ensuring billet surface quality, dimensional precision and casting stability. Their performance is crucial for metallurgical production efficiency and product quality, being indispensable.

The following is several correct methods for using Copper Mould Tubes

Corrosion-Resistant Choices: Use TP2 for copper mould tubes to better improve the welding performance. For coastal areas, Cu-Ni or titanium-coated tubes double service life to 12–15 years. Chrome-plated tubes resist 300°C high temperatures for solar systems.

Precise Installation & Use: Ensure wall thickness tolerance ≤±0.02mm to avoid stress cracks. Anneal cold-worked tubes at 350–400°C (nitrogen atmosphere) to retain flexibility. Braze high-pressure joints to prevent leaks and corrosion.

Routine Upkeep: Install 5–10μm filters to keep fluids clean and avoid internal scratches. Descale heat exchangers yearly with citric acid to maintain thermal efficiency. Recycle scrap tubes—recycled copper retains 95% of original properties.

3.Conclusion

Efficient use of rolling rolls relies on material-process-maintenance synergy, while copper tube longevity hinges on corrosion resistance and careful upkeep. These strategies reduce replacement costs by 30–50%, minimize downtime, and support sustainable manufacturing—delivering tangible value to industrial operations.
