Summary:PURPOSE:To increase the C concn. at the upper layer of the mixed material without deteriorating the permeability of the mixed material layer at the time of operating a Dwight-Lloyd sintering machine by charging a powdery carbonizing material into the charging part formed in the upper layer of the mixed material on a pallet. CONSTITUTION:The mixed material 9 in a feed hopper 2 is discharged onto the pallet 1, its upper surface is smoothed by a cutoff plate 4 as the pallet 1 is traveled in the A direction. Since the tips of the slitting rods 13 fixed to the plural branch pipes 12 branched from the lower end of a breeze hopper 5 are positioned at a specified depth from the upper surface of the material layer 9, plural slit grooves 16 are formed to a constant depth in the upper material layer 9. Coke powder 10 in the hopper 5 is charged into the grooves 16 from a long hole-shaped opening 15 with its longitudinal direction almost parallel to the direction A and provided at the lowermost part of the branch pipe 12.
