- Suitable for square, round, rectangular and special-shaped billets.
- Customized according to drawings, caster conditions and project requirements.
Application
Continuous casting machine
Material
TP2 / CuAg copper alloy
Types
Square, round and special-shaped
Customization
Produced by customer drawings
Product Overview
- The copper mould tube is a key part of the continuous casting machine.
- It helps molten steel cool down and form the required billet shape.
- It works at the center of the casting process and directly affects billet quality.
- Excellent thermal conductivity is required for fast heat transfer.
- High mechanical strength helps support stable operation.
- The final specification depends on the customer's caster and drawings.
How It Works
1
Molten metal is poured from the furnace into a ladle.
2
The metal flows from the ladle into the tundish through a shroud.
3
The metal enters the top of the open copper mould tube.
4
The copper mould tube guides solidification and helps form the billet.
Material Options
- Copper alloy is generally used as the main material.
- Common option: deoxidized phosphorus copper TP2.
- Another common option: silver-bearing copper CuAg.
Available Types
- Square copper mould tube.
- Round copper mould tube.
- Rectangular copper mould tube.
- H-shaped and other special-shaped copper mould tubes.

Important Notes
- The service performance of a copper mould tube is not calculated simply by the number of uses or years of operation.
- It mainly depends on steel throughput, namely how many tons of molten steel can pass through one copper mould tube.
- Product quality is important, but it is only one part of the overall performance.
- Dimensions, wall thickness, matching accuracy, cooling performance, taper design and caster operation may all affect actual performance.
- Therefore, we do not provide a guaranteed steel throughput.
- Besides copper mould tubes, we can also supply mould assemblies, water jackets and other continuous casting components.

TECHNICAL FAQ
Frequently
Asked
Questions
Practical answers about copper mould tube materials, applications, maintenance, and common use questions in continuous casting.
01 What is a copper mould tube, and what is it used for? +
The copper mould tube is the core component of the continuous casting machine, directly in contact with high-temperature molten steel. Its main function is to rapidly cool and solidify the molten steel into a solid shell of a certain thickness and shape, providing the initial shape and size, such as square billets, rectangular billets, and round billets, for the cast billet.
02 What is the main material of copper mould tube? +
It is usually made of high thermal conductivity copper alloys, such as phosphorus-deoxidized copper (TP2), silver-copper (CuAg0.1), or chromium-zirconium-copper (Cr-Zr-Cu), to enhance high-temperature strength, wear resistance, and creep resistance.
03 Why does a used copper mould tube turn black? +
The blackening of copper tubes in steel plant moulds may be caused by multiple factors, including oxidation, corrosion, and sedimentation. To prolong the service life of copper tubes, regular maintenance and upkeep are necessary. Steel plants can also use cleaner water to clean the moulds, which helps reduce oxidation and sediment buildup, lowering the likelihood of the copper tubes turning black.
