Abstract
A method of preventing a raw mix disposed on a pallet of a moving grate type sintering machine from being unevenly sintered in the transverse direction extending across the width of the sinter and an apparatus for carrying out the method are disclosed. The raw mix is fed on moving pallets which form the bed. The temperature distribution of waste gas soon after it has passed through the bed in a direction perpendicular to the bed is measured at the sinter exit side of the sintering machine. The temperature thus measured is utilized to adjust the amount of raw mix to be delivered from a surge hopper upon the pallet and adjust the density of the packed layer and hence correct the gas-permeability of the bed and the sintering effect upon the bed in its transverse direction. Thus, the sintering bed is prevented from being unevenly sintered by the sintering machine.
