The function of Copper Mould is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification. The mould must exhibit excellent thermal conductivity, be resistant for thermal
Metal Mould1- TP2
This kind of material is selected by most of steel plants. It shows excellent heat-proof and anti-fatigue property under high temperature and it has good processing property.
Metal Mould2-CuAg
Adding 0.08%-0.12% silver during copper ingots melting will increase the re-crystallization temperature of copper by 100℃, which will increase the heat stress and anti abrasive property of copper mould tube interior surface, showing better heat resistant property than TP2.
FilterMetal Mould3-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. These outstanding features make it different from the previous copper alloys. It combines all good properties together. But compared with other copper alloys, Cu-Cr-Zr is difficult to be formed with higher products costs.
