摘要:
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 burning 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.

The invention relates to a conveyor belt to be used in a continuously operated conveyor-type thermal treatment, i.e. sintering, of a material bed. The conveyor belt is 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. 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 gases to flow through, said element being mechanically connected to the preceding and successive element (1, 11, 21) in the proceeding direction (5, 15, 28) of the conveyor belt by means of a junction made in the lateral direction of said conveyor belt, and the perforations (2, 13, 14, 26, 27) are arranged in zones alternating with perforation-free element pats.

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 (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), and 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.
