Copper Mould Tubes for Continuous Casting
The copper mould tubes sit at the heart of a continuous casting machine, shaping molten steel into solid billets with speed, precision, and reliability. Made from high-conductivity copper or copper alloys, it draws heat from the steel at a controlled rate, forming a solid shell without causing internal cracks or surface defects.

Key Functions of Copper Mould Tubes
- Rapid Heat Transfer – Copper’s excellent thermal conductivity pulls heat away from molten steel almost instantly, creating a strong initial shell.
- Dimensional Accuracy – Precision machining ensures every billet meets tight size tolerances.
- Surface Quality – Uniform cooling reduces the risk of surface cracks, laps, or scabs.
Design Options
We tailor copper mould tubes to match casting requirements, offering:
- Shapes – Square, rectangular, round, bloom or beam blank profiles.
- Lengths – Optimized for machine layout and billet size.
- Dimensions
- Square billet Copper Mould 60*60~700*700mm
- Round billet Copper Mould 80*80~1000*1000mm
- Rectangular billet Copper Mould 135*430~550*720mm
- Material – DHP, CuAg, CuCrZr
- Coatings – Nickel, chromium, or other wear-resistant layers to extend service life.
Advantages in Steelmaking
- Stable shell formation for higher casting speeds.
- Reduced downtime through longer mould life.
- Consistent billet quality for downstream rolling and forging.
A high-performance copper mould tube doesn’t just handle heat — it drives productivity, product quality, and process stability in modern steel plants. Choosing the right design and material ensures every cast starts strong.
