Abstract

Изобретение относится к способу повышения усталостной долговечности конвейерной ленты (1) протяжной печи для спекания и к конвейерной ленте (1). Конвейерная лента (1) выполнена из прямоугольных стальных пластинчатых элементов (2), которые последовательно сварены между собой сварными швами (3). Каждый пластинчатый элемент (2) содержит отверстия (4), расположенные группами (5), для обеспечения прохождения газа, используемого в процессе спекания. Конвейерную ленту (1) обрабатывают с целью создания остаточных напряжений сжатия на поверхности конвейерной ленты, по меньшей мере, в критических областях, которые подвержены усталостному разрушению. Конвейерная лента (1) содержит остаточные напряжения сжатия на своей поверхности, по меньшей мере, в критических областях, которые подвержены усталостному разрушению. Таким образом повышают усталостную долговечность конвейерной ленты.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.
