ABSTRACT:
By means of at least one radiation pyrometer, the radiation emission emerging at the surface of the peripheral wall of a centrifugal ring is continuously detected and used for process control as an actual value in a control circuit for hot gas flow. In consequence, optimum management of the centrifugal ring temperature is achieved and automation of the fibering process made possible, while at the same time harmful over-heating and shock-like temperature changes of the centrifugal ring are avoided.
