Abstract
A blower rotates continuously at constant speed in the protective gas atmosphere, driven by an electric motor. The current supplied to the motor is measured. During the holding phase (B) at constant high temperature, variation of current consumption by the motor forms a signal for control of the heat treatment process and/or for controlling the replacement rate of protective gas atmosphere.
