Characteristic of Raw Mix Packed Structure on Sinter Strand with Chute Type Feeder and Its Effect on the Sintering Reaction

Abstract

Details of raw mix packed structure with current chute feeder and their effect on sintering reaction were analyzed. The chute feeding method cannot avoid the problem of avalanches, which makes it difficult to enlarge and control the degree of grain size segregation in the bed height by making simultaneously the sandwich-like structure of fine and coarse particles. The larger the raw mix feed, the larger the avalanches and the disturbunce of sintering reaction. Enlargement of continuous material grain size segregation in the bed height without sandwich structure is effective in improving both yield and productivity by homogenizing sintering in the sinter bed.
