2012 Wire heating machine

Wire heating machine (From a Plant for fire aluminizing steel wire)

Wire heating is inductive, 12 wires are heated simultaneously by a coil.

The frequency of the inductor is tuned to 12 wires. To prevent interference with the HF generator, at least 10 wires must be moved within the coil.

Inside the inductor, the wires are guided through 12 ceramic tubes which are mounted inside the induction coil. The ceramic tubes prevent contact with the coil. To prevent the ceramic tubes from breaking, the wires should be guided through the tubes as centred as possible.

The wires are heated to coating temperature inside the inductor and the temperature is measured using a radiation thermometer (pyrometer).

The heating power of the inductor is preselected and the power is regulated automatically in line with the change in speed of the wire. In practice, this means that the power adjustment of the basic power value, e.g. 35 % at a wire speed of 10 m/min, is analogue. The power increases according to a calculated formula with increasing wire speed up to 85% at 60 m/min with a wire diameter of 2 mm.

Forming gas, 95.5% nitrogen gas and 4.5% hydrogen gas is fed into ceramic tubes via the link box. The forming gas has a reducing effect on the wire surface and protects the wire from oxidation by the oxygen in the air during annealing.

The link box must not be opened during operation.
