Abstract

The invention relates to a an arrangement and a method for heating metal objects such as metal bars by convection. The metal objects are passed on a conveyor through a series of chambers where hot air is blown through the conveyor. The temperature is controlled by a sensor connected to a control devise such as a thyristor.
