Abstract (en)
The grate roll, of conventional structure, has a framework in the form of a cylindrical cage with longitudinal members (10) with a T- shaped profile arranged according to generating lines, and a lining formed from groups (G) of rings separated by gaps (i) for blowing oxidant air, the rings being segmented into bars ((1-6).11, (1-6).11') in the form of arcs which extend between the longitudinal members. According to the invention, in order to limit the clearance of the bars while leaving them play, they are, attached on one side by an indentation to the wing of a longitudinal member, held in position by bosses ((1-6).128, (1-6).129) of an interposed piece (12) bolted longitudinally onto the longitudinal member; the bars ((1-5).11, (1- 5).11') have recesses at their end which is contiguous with the intermediate piece (12), in which the bosses engage. The bars are thus attached with limited clearance in the axial, radial and peripheral directions in relation to the roll. <IMAGE>
