The invention relates to a device for moving the belt of a belt conveyor used in continuously operated belt sintering between the drawing drum and the folding drum, and for aligning the belt sintering belt to be moved by the belt conveyor with respect to the sintering device. According to the invention, in order to rotate the drawing drum ( ) of the belt conveyor used in belt sintering, in the immediate vicinity of the other end of the drawing drum, there is installed an actuator device ( ) of the belt conveyor, where in at least one rotary element ( ) that is installed co-centrically with the axis ( ) of the drawing drum and cogged on the outer circumference, there is connected at least one actuator element ( ) that is essentially smaller in diameter and cogged on the outer circumference, which actuator element ( ) can be made to rotate by means of an actuating motor ( ) belonging to the actuator device. Moreover, in order to align the belt ( ) of the belt conveyor with respect to the sintering device ( ), the actuator device of the belt conveyor is installed, with respect to the belt conveyor, so that the aligning of the belt ( ) of the belt conveyor can, when necessary, be carried out essentially by moving the whole actuator device ( ) of the belt conveyor.

Device for continuously operated belt sintering

The invention relates to an arrangement and method for heating gases in a gas circulation duct in connection with continuously operated sintering. In the sintering furnace, hot gas is fed in from above the belt in order to sinter the material located on the belt, and part of the gas circulation duct is formed as a burning zone, a burner ring, where the gas is heated. The burner ring comprises at least one burner unit directed inwardly from the circumference of the gas circulation duct.

Arrangement and method for heating gas in a gas duct in connection with continuously operated sintering

The invention relates to a device for supporting a conveyor belt used in the continuously operated thermal treatment, i.e. sintering, of a material bed. According to the invention, in the top part of the frame structure of the belt conveyor, there is installed at least one support element, whereby an essentially smooth slide surface can be obtained for the conveyor belt, and in the interior of the support element there is made a channel system in order to enable the flow-through of the intermediate agent fed into the support element.
