Casting Rod Producton Lines
TMetal’s Casting Rod Production Line produces high-performance cobalt alloy rods for demanding applications such as aerospace engines, gas turbines, and medical implants.
This precision system integrates:
1. Vacuum Melting & Refining
- VIM furnaces (1600–1800 °C) with oxygen control below
10 ppm - Secondary refining via ESR or VAR
- Automated composition control using XRF spectroscopy
2. Directional Solidification
- Water-cooled copper molds with thermal gradient control
- Liquid Metal Cooling (LMC) for single-crystal growth
- Adjustable withdrawal speeds (0.5–10 mm/min)
3. Hot Processing
- Precision extrusion presses (10:1–20:1 ratio)
- Multi-stage hydrogen annealing furnaces
- CNC centerless grinding with ±0.01 mm tolerance
4. Quality Assurance
- X-ray inspection detecting voids ≥ 50 μm
- EBSD for crystal orientation analysis
- Full-length ultrasonic testing for internal defects
This line achieves near-net-shape production with 92-95% material yield, meeting AMS, ASTM and ISO standards for critical applications.
