Abstract
In a method and apparatus for continuously measuring the annealing level on wires or strips, a wire or strip is passed, in a continuous feed, over a pulley of small diameter, at a tension less than that corresponding to the elastic limit of the material of which the wire or strip is made, so as to produce permanent elongation of 0.1 to 1%, this elongation being taken as a measurement of the annealing level, and utilized to control the annealing level.
Claims5
A method of continuously measuring and adjusting the annealing level on wires or strips comprising the steps of receiving a wire or strip from a continuous annealing installation, passing the wire or strip in a continuous feed over a deforming member at a tension less than that corresponding to the elastic limit of the wire or strip, selecting the configuration of the deforming member and the tension so that passage over the deforming member causes permanent axial elongation of the wire or strip within a predetermined range, and sensing the elongation for controlling the parameters of the annealing operation.
