Copper Casting Wheels CuCrZr
For ESR copper mould tubes, it could be supplied as welded or forged.The material:1. TP2 also known as M1φ,CU-DHP or SF-CU DIN 1787, is for welded type2. T2 also known as M1, ASTM C11000 or DIN E-CU58
CuCrZr Casting Wheels for Wire & Cable Continuous Casting Mills
Precision Engineered for High-Efficiency Metal Solidification
Core Design Advantages
✅ Material Superiority
Alloy Composition: CuCrZr (Cr 0.6–1.0%, Zr 0.1–0.2%, Cu balance) with nano-scale Cr/Zr precipitates.
Mechanical Performance:
Yield Strength: ≥450 MPa (hot working conditions)
Elongation: ≥18% (post-aging treatment)
Fatigue Strength: 300+ MPa at 10⁶ cycles (ASTM E466)
✅ Thermal Management
Integrated Water Cooling: Multi-channel design achieves 2500 W/cm² heat flux, reducing molten bath temperature by 40%.
Thermal Crack Resistance: Grain-boundary Zr segregation minimizes stress concentration, enabling >5,000 thermal cycles (300°C ↔ water quench).
✅ Process Efficiency
Direct Solidification: Eliminates remelting, saving 35–50% energy vs. conventional methods.
Continuous Operation: Casting speeds up to 25 m/min with ±0.05 mm diameter tolerance.
