| The movement behavior of fine sinter in hearth layer has been known to be influenced by suction pressure, particle size of sinter and charging condition of hearth layer i.e., the ratio of the height of upper hearth layer to that of lower hearth layer. In this study the behavior of fine sinter has been investigated using sintering pot simulator. From our experimental results, especially the charging condition among the factors has been found to have a great influence on the movement behavior of fine sinter. When the suction pressure in sinter bed was increased, the weight loss of fine sinter was increased. The weight loss of fine sinter was also decreased with the height of lower hearth layer. The optimum charging conditions are obtained as follows : (a) When the particle size of sinter in upper hearth layer is over 3 ㎜, the amount of fine sinter remains unchanged during the suction. (b) The weight loss of fine sinter in hearth layer is severe when the height of lower hearth layer is below 10 ㎜. |
