Aluminum Rotary Hearth Ovens
Aluminum Rotary Hearth Ovens
Aluminum rotary hearth furnaces are designed for continuous pre-heat precision forging process. They assure temperature uniformity repeatability less than ±6°C (±10°F). Furnaces from this type are characterized by large scale production.
- NADCAP
- AMS 2750D, class 2 furnaces
- RPS953
- One frame includes all sub systems
- Reinforced steel outer frame
- Base of furnace on 3 wheels for mobility and 3 adjustable jacks to stabilization in desired location • Hearth rotation by gear motor with torque limiter
- Hooded foot pedal for rotation
- Opening/closing of door by manual pneumatic valves
- Conveniently located port holes for T/C placement to perform TUS covering the working volume.
- Temperature uniformity less than ±6°C (±10°F) • Tubular type heating elements installed vertically and easily replaceable.
- Thyristor control system for linear power control of the heating elements.
- Digital temperature controllers with communication interface
- Frequency inverter for speed control as per customer specifications.
- Type "K" thermocouples.
