Abstract
The effects of temperature gradients across the belt width on fired resistor values are well known and become increasingly important in wide belt production conveyor furnaces. This paper discusses the experimental and theoretical study of this problem. Physical data were collected from experiments and the results were analysed statistically. Particular attention was paid to the exit end firing zone because heat losses from this zone differ from that of the other zones. High resistor values at the centre of the belt, gradually decreasing towards both sides, have been observed. This phenomenon seems to be caused by loss of heat radiation to the exit opening at the belt centre. Mathematical models using the basic laws of heat transfer as they apply to the particular structure of the furnace have been developed. The study shows that it is possible to reduce the range of fired thick film resistor values by modifying the temperature conditions near the end zone.
