Abstract

In the annealing process according to the parent Specification, in which a magnetically loaded electrical conductor is led through a continuous annealing furnace at about 950 DEG C. before it is treated coiled up in a pot at about 475 DEG C., the conductor emerging from the continuous furnace is fairly rapidly cooled, for instance at a rate of between 300-400 DEG C. a minute till it approaches 100 DEG C. This cooling takes place in a cooling tube of the same length as the furnace tube, and on leaving the cooling tube the conductor passes through a jet of water to reduce it to atmospheric temperature. The desired final permeability of the loading is obtained by regulating the pot annealing which may last about four hours. During the pot treatment the loaded conductor may be shielded from the atmosphere by surrounding it with copper.
