Abstract

The invention relates to a heat treatment method, in which method an object/objects is/are heat-treated, in which method the heat treatment takes places in a heat treatment furnace or the like. In the method, in connection with heat treatment, heat transfer of the object/objects is controlled by adjusting the rate of change of the temperature of the object/objects being heat-treated to the desired level in different heat treatment phases.
