METHOD OF INCREASING THE FATIGUE DURABILITY OF THE CONVEYOR BELT OF THE EXTENSION FURNACE FOR SINTERING AND CONVEYOR BANDS

摘要

The invention relates to a method for increasing the fatigue life of a conveyor belt (1) of a broaching sintering furnace and to a conveyor belt (1). The conveyor belt (1) is made of rectangular steel plate elements (2), which are sequentially welded together by welds (3). Each plate element (2) contains openings (4) arranged in groups (5) to ensure the passage of gas used in the sintering process. The conveyor belt (1) is processed to create residual compressive stresses on the surface of the conveyor belt, at least in critical areas that are subject to fatigue failure. The conveyor belt (1) contains residual compressive stresses on its surface, at least in critical areas that are subject to fatigue failure. In this way, the fatigue life of the conveyor belt is increased.
