This invention relates to sintering apparatus of the type in which a series of pallets or traveling grates carrying the sintering mix passes over a succession of wind boxes with in which a sub-atmospheric pressure is maintained whereby hot gases or air is drawn down through the charge moving thereover and is for an improved seal between the pallets and wind boxes for apparatus of this kind. The improvement in said seal resides in the use of a replaceable, non-lubricated, sliding seal between opposite sides of the grate and the slide bars mounted upon the upper face of the wind boxes or the supports therefor with contact maintained by spring pressure. Thus the mounting of the sealing bars upon the grate is accessible when the sealing device is not seated upon the slide bars of the wind boxes. The grates are supported, upon opposite sides, by a wheel and axle mounted upon guide rails at opposite sides of the wind box openings.
