Zusammenfassung:	In a grate bar for use in supporting grate keys, a casting of high carbon steel is formed having a web portion and integral upper and lower flanges therewith, and a series of gussets and end plates to provide the structure for strengthening and securement of the grate bar to the drive link and slide block customarily found in an incinerator or conveyor. The upper flange of the grate bar incorporates a slot to facilitate the insertion and mounting of the various keys while the arranged gussets are formed having a reduced dimension proximate their upper portions to provide clearance for the lateral shift of the keys during their installation. The entire grate bar, and generally its web and flange portions are designed having a tapered shape when viewed in cross section, with the thickest portion of these bar components being located at the juncture between the web and the lower flange to withstand the maximum stress that is usually generated and focused at this location in a grate bar.
