Abstract

PURPOSE: To sinter effectively the powdery ore, by making the grain size of coke coarser than the prescribed grain size and reducing the amount of air to be sucked in according to the improvement of gas permeability of the sintering layer.
CONSTITUTION: When the powdery ore is sintered with the sintering machine in which air is sucked in from the lower side, the grain size of fuel coke is made coarser, for example, above 1.6mm in the average diameter. And, by controlling so as to reduce the amount of air to be sucked in according to the improvement of gas permeability of the sintering layer, the period of time for sintering is made to do not become excessively short. In order to reduce the amount of air to be sucked in, the operation is carried out, for example, by controlling the opening and closing of the damper of the flue or lowering the capacity of the blower. In this way, the quality is improved and the generation of NOx is suppressed
