The invention relates to a conveyor belt for a continuously operated conveyor- type thermal treatment, i.e. sintering, of a material bed. The conveyor belt being provided with perforations in order to allow the gases that are used for heating and possibly cooling the material bed to flow through the material bed and the conveyor belt, and said conveyor being based on elements connected to each other. According to the invention the conveyor belt is made of a perforated, at least one-part element (1, 11, 21) made of a metal piece and allowing the gas to flow through, and that the perforations (2, 13, 14, 26, 27) are arranged in perforation zones (3, 12, 24) alternating with perforation-free zones (5), and that the area of the perforations (2, 13, 14, 26, 27) is about 1 - 60% of the total area of the conveyor belt. |
