Tunnel demagnetiser ENTMAG T

ENTMAG tunnel demagnetisers allow small and large ferrous parts to be demagnetised simply and quickly. The workpiece is moved through the tunnel by hand, via a chute or in free fall. Demagnetisation is complete only once the workpiece has left the device and is approx. 300 mm away from it. Workpieces should be demagnetised one at a time; clusters must be avoided. The unit is a durable, moisture-protected built-in device with a steel casing. Residual magnetism can be reduced to below 0.5 mT (5 Gauss).

Tunnel demagnetisers are usually integrated into systems; the workpieces are guided through the demagnetiser on a roller conveyor, for example.

Why demagnetise? All ferrous and ferromagnetic materials can develop magnetic zones. This can happen during raw material storage, magnetic crack and hardness testing, cold forming, machining, measuring, or magnetic clamping and lifting.

Magnetism is basically not harmful, but it can interfere with further processing.

Demagnetising neutralises the magnetic field in the workpiece, leaving it magnetically neutral. The demagnetising effect can be achieved by intense heating or by a very strong external magnetic field. After demagnetisation, the magnetic forces in the workpiece have disappeared. The magnetic field can be restored by remagnetisation.
