Copper Mould Tube
Copper Mould Tubes are the most essential part of a Continuous Casting Machine. These help in solidifying Liquid Metal in Continuous Casting Machine for producing Steel Billets.
Material
- Metal Mould -TP2
- Metal Mould -CuAg
- Metal Mould -CuCrZr
Copper Moulds are situated in the heart of continuous casting machine
Mould requires extreme high thermal-conductivity and high strength. The molten steel will be formed into a certain shaped steel billets immediately after it passes through the copper tube.

Mould Material
At present, Deoxidized phosphorus copper (TP2), Silver-bearing copper (CuAg0.1) and Cu-Cr-Zr are normally selected as the material to produce copper mould tubes.
Metal Mould -TP2
This kind of material is selected by most of the steel plants. It shows excellent heat-proof and anti-fatigue property under high temperature and it has good processing property.
Metal Mould -CuAg
Adding 0.08%-0.12% silver during copper smelting, increase the re-crystallization temperature of copper by 100 C, which will increase the heat stress and anti-abrasive property of copper mould tube interior surface, showing better heat- resistant property than Tp2.
Metal Mould -CuCrZr
Cu-Cr-Zr is a kind of copper alloys which can be normalized by time. It has excellent mechanical property under both room temperature and high temperature. It has high heat conductivity, melting point, anti-fatigue and anti heat stress properties.
