Product Description
JISteel Brand Copper Mould Tube for CCM
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. Copper Mould Tube 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.
Copper Mould Tube 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.
TP2/Cu-DHP
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
CuAg
Adding 0.08%-0.12% silver during copper ingots melting will increase the re-crystallization temperature of copper by 100 ºC, which will increase the heat stress and anti-abrasive property of copper mould tube interior surface, showing better heat- resistant property than Tp2.
Cu-Cr-Zr
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 difffferent 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.
Mould Coatings
The chrome plating thickness recommended by CCM will be controlled in the best range. As for the coating of copper mould plates, based on our 20 years of experience, we can provide professional Chrome coating, Ni-Cr coating, Ni-Fe coating and Ni-Co coating to meet the demand of various customers both at home and abroad
