Application:
A continuous bright annealing furnace is used for bright annealing of copper straight tubes (or rods), steel tubes, aluminum tubes, or wire coils of various specifications under a controlled atmosphere.
Features of a Continuous Bright Annealing Furnace
- Workpieces pass continuously through preheating, heating, soaking, slow cooling, and cooling, and are not limited by length.
- The transmission system uses roller-type synchronous drive with variable frequency speed control, ensuring smooth and reliable operation.
Mesh-Belt Bright Annealing Furnace
- Uses a protective atmosphere and strong hot-air circulation, ensuring uniform temperature and a bright, clean inner and outer surface.
- The specially designed cooling zone guarantees uniform cooling of the workpieces.
- Products processed with this furnace have bright surfaces inside and outside, high quality, and high production output.
