1. A device for supporting a conveyor belt used in the continuously operated thermal treatment, i.e. sintering, of a material bed, which device enables an essentially unobstructed passage of the process gases to the conveyor belt and further through the apertures provided in the conveyor belt, and in the top part of the frame structure (17) of the belt conveyor (14), there is installed at least one support element (1,18), whereby an essentially smooth slide surface can be obtained for the conveyor belt (11), characterized in that in the interior of the support element (1,18) there is made a channel system (8) in order to enable the flow-through of the intermediate agent fed into the support element (1,18) for cooling or heating. 2. A device according to claim 1, characterized in that the interior of the support element (1,18) is formed of end parts (2) and of at least two supporting parts (3) connecting the end parts. 3. A device according to claim 2, characterized in that the supporting parts (3) are mutually parallel and spaced apart. 4. A device according to any of the preceding claims, characterized in that the support element (1,18) is provided with conduit members for feeding (4) intermediate agent into the support element and for removing (5) intermediate agent from the support element. 5. A device according to any of the preceding claims, characterized in that the support element (1,18) is provided with at least one adjusting member (7) in order to adjust the height of the support element.
