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.
