Abstract
A grate bar for mounting in arrays of adjacent grate bars in a pallet car of a sintering or pelletizing machine includes an elongate crossbeam extending in a longitudinal direction of a horizontal plane, with a middle section between two opposite end sections. The crossbeam has a generally rectangular cross-section with an upper surface for receiving bulk material thereon, an opposite lower surface, and peripheral surfaces for facing adjacent grate bars. The crossbeam has two legs to vertically secure the grate bar to the pallet car. The end sections of the crossbeam include first interlocking components shaped and arranged such that they cooperate with first interlocking components of grate bars of a neighbouring row of grate bars; thereby limiting relative translations of two neighbouring grate bars in at least a vertical and a horizontal orientation. The first interlocking means components have a triangular cross-section in a horizontal plane.
