Abstract
A furnace muffle for an annealing furnace, the furnace muffle including a base body arranged to delimit a volume to be heated, at least one actuator connected to the base body in such a manner that the actuator, during the operation of the furnace muffle, can exert a force on the base body, at least one sensor arranged to detect a force exerted by the base body during the heating or cooling and/or a change in a length of the base body during the heating or cooling, and a control device connected to the actuator and the sensor, which is arranged so that during the operation of the furnace muffle, it controls the force exerted on the base body as a function of the force or change in length detected by the sensor.
