Resistance annealing machine stainless steel wires from 0.30 - 0.50mm

Resistance annealing machine

This machine anneals (thermally straightens) stainless steel wires from 0.30 - 0.50mm).

FUNCTIONAL DESCRIPTION:

- The machine enables heating by direct passage of electric current through the wire

through the wire (resistance annealing process).

The device is equipped with 4 special power stabilisers for regulation, in combination

with an optical pyrometer for temperature control and thermoregulation.

- The simultaneous heating of the 4 wires takes place in a chamber saturated with inert gas

by the electrical contact transmitted by two conductive V-shaped discs (short-circuit rollers).

are transmitted. Two further V-shaped discs have the task of guiding the wires.

- The system can be integrated into an existing automatic Scholl disc system, which, however, is not

not included in the scope of delivery of the machine. Alternatively, the straightened wire can also be

be placed on a spool by the customer.
