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.
