Continuous bright annealing furnace (Heating Treatment)

Bright annealing furnaces are widely used for the bright annealing of non-ferrous metals (such as copper and aluminum alloys) and ferrous metals (such as plain carbon steel, silicon steel, and alloy steel) in the form of coils, coiled tubes, and wires. By precisely controlling heating, holding, and slow cooling, this equipment significantly improves material plasticity and workability.

Annealing is a heat treatment process in which metal materials are heated to an appropriate temperature, held for a certain period, and then slowly cooled. Common annealing processes carried out in bright annealing furnaces include:

1.Recrystallization annealing

2.Stress relief annealing

3.Spheroidizing annealing

4.Full annealing

1.Reduce metal hardness and increase plasticity for machining or pressure forming

2.Reduce residual stress and improve microstructure and composition uniformity

3.Prepare the microstructure for subsequent heat treatment processes

Applications

Suitable for the continuous bright annealing of various specifications of copper straight tubes (bars) , steel tubes , aluminum tubes , or coiled rods under a controlled atmosphere.

Key Features

1.Workpieces continuously pass through preheating, heating, soaking, slow cooling, and cooling sections – no length limitation

 2.Roller table synchronous drive with variable frequency speed regulation for smooth and reliable operation

3.Hot atmosphere circulation with protective gas ensures uniform temperature and bright inner/outer surfaces

4.Unique cooling zone design guarantees uniform cooling of workpieces

5.Processed products feature bright inner and outer surfaces, high quality, and high productivity

1.Wide material applicability : Covers copper, aluminum alloys, plain carbon steel, silicon steel, alloy steel, and more

2.Comprehensive process coverage : Supports recrystallization annealing, stress relief annealing, spheroidizing annealing, and full annealing

3.Multiple material forms : Suitable for coils, coiled tubes, wires, etc.

3.Superior equipment performance : Forced convection design ensures temperature uniformity, energy efficiency, and high productivity
