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:
