Induction annealing equipment, type KGA

• Easy to control
• Saves energy
• Fast response
• Fast operation
• In-line operation
• Friendly to the environment

The machine is built up of four units:
– Transformer
– Control panel
– Annealing device
– Water colling device

 

Features/benefits

The element is fed onto a conveyor belt, which runs with the same speed as the rolling mill.
On the side of the belt, there is a movable micro switch. When this switch is activated, the
element is pushed down onto the annealing jaws, and annealed by resistance heating.

As soon as the element is in position, the annealing jaws goes down and clamps the element.
The jaws are energized and annealing takes place. After annealing, the element is pushed
out of the jaws and falls onto a walking beam system with a cooling path.

There are three parameters to be set:
– Voltage
– Current
– Time

The parameters are set based on experience. Some general values for stainless steel and
copper are available:

Copper tube Ø8,0 x 0,6 mm                                                                                                                                                                                          annealing length: 200 mm                 time: 5 s
temp: 600-800°C                                 transformer setting: 7,5 V

Stainless steel tube Ø8,0 x 0,6 mm
annealing length: 200 mm                 time: 5 s
temp: 1100°C                                         transformer setting: 30 V
