ABSTRACT:
A device for continuously heat-treating continuously cast or formed metallic goods, particularly wire and the like. The device comprises a first annealing path in which the continuously formed metallic goods are guided by means of two contact rollers. The first and second contact rollers are arranged at first and second ends, respectively, of the first annealing path. Moreover, the first and second contact rollers are connected to a voltage source such that a current flows through the continuously formed metallic goods between the first and second contact rollers. The device further comprises a second annealing path similar to the first annealing path. The device further comprises a third annealing path in which the continuously formed metallic goods are guided by means of two contact rollers, the fifth and sixth contact rollers are arranged at first and second ends, respectively, of the third annealing path, and wherein a switching means is further provided by which the fifth and sixth contact rollers may be connected to a voltage source such that a current flows through the third annealing path, if the switching means is in a first switching position and such that no current flows through the third annealing path, if the switching means is in a second switching position.
