    摘要： The present invention relates to an apparatus for continuous-direct-resistance heating of long-length articles wherein the travelling long-length article is made to contact with roll electrodes disposed in a specified spacing, then made to pass through an annular transformer disposed between the roll electrodes.Conductive members with sufficiently less electrical resistance than that of the long-length article located between the both electrodes are disposed on the periphery of the transformer with the both ends thereof connected to the roll electrode through a slider, thereby a current being induced in the long-length article with the conductive member as the retrace, which heats the long-length article having a higher resistance very efficiently, but does not result in an external voltage nor any electrical hazards along the production line in which the apparatus is installed.One embodiment of the apparatus comprises three roll electrodes, two transformers and conductive members being disposed on the periphery of the transformer connected to the neighboring roll electrode, the power being fed to each transformer from two single-phase transformer in a Scott connection with a three-phase power supply, thus providing heating without developing imbalance in the three-phase voltage.

    摘要： Disclosed is an improved system for annealing strand of the type comprising at least two sheaves across which the strand passes and becomes electrically annealed, the improvement comprising a first flange member, a second flange member concentric with the first flange member and adjacent thereto, and an annealing band positioned between the first and second flange members and forming the bottom of a sheave groove, further provided that the annealing band is adapted to center strand being annealed to prevent contact between the strand and either of the flange members thereby providing a renewable, strand centering annealer sheave adapted for long life.
