| titleOfInvention | Treatment of continuous lengths of metal by electrical resistive heating |
| abstract | An apparatus for heat-treatment of continuous lengths of metal, particularly continuous bands, strips, sheets or wires of ferrous metal, to effect the annealing or tempering thereof, and/or the reduction of the oxides thereon, preparatory to the passage thereof through a liquid treating bath, for example, a molten metal coating bath, such as aluminum, zinc, tin or the like, if an effective protective corrosion-resistant coating on the ferrous metal is sought to be attained. The continuous length of metal is heated by the direct application of electrical energy thereto as the same travels between conveyor or guide rolls to which the electrical potentials are applied to generate heat, by the Joule effect, in the transient lengths between the rolls, while the metal travels in otherwise unheated chambers, which may contain a suitable protective gaseous atmosphere. The spacing between the conveying rolls is diminish-ed, corresponding to the increasing thermal content of the travelling length of metal beyond the inlet and towards the outlet, and the eventual treating bath, to equalize the electrical heat energy, represented by the product I2R, in the successive lengths between the rolls, to compensate for the higher resistivity of the hotter lengths of metal in the advanced path thereof, so that the current loadings of the multiple stages of the power supply are substantially equalized. |
