METHOD FOR ENHANCING FATIGUE DURABILITY OF A CONVEYOR BELT OF A STRAND SINTERING FURNACE, AND CONVEYOR BELT |
摘要 |
<p>The invention relates to a method for enhancing fatigue durability of a conveyor belt (1) of a strand sintering furnace, and a conveyor belt. The conveyor belt is formed from a number of rectangular steel plate elements (2) that are sequentially welded to each other by weld seams (3). Each plate element (2) includes a plurality of holes (4) arranged into a plurality of groups (5) of perforations to enable the flow-through of the gas used in the sintering process. The conveyor belt (1) is treated to create compressive residual stresses at a surface of the conveyor belt at least in critical regions which are susceptible to fatigue breakage. The conveyor belt (1) includes compressive residual stresses at a surface of the conveyor belt at least in critical regions which are susceptible to fatigue breakage. Thereby the fatigue durability of the conveyor belt is improved.</p> |
