Abstract：The influence of different proportions of sintering powder and sludge and different size-distribution of pelletizer on the sintering process index were studied by a series of sinter pot (300mm×750mm) test and disc-type pelletizing machine. The results show that when the proportions of sintering power and sludge increased from 0 to 100%, the cold bed permeability index increased for 31.5%, and the sinter yield increased for 24.8%. When size-distribution of pelletizer was changed and ranged from 5 to 10mm, the sinter yield and coefficient of utilization respectively maximized to 84.34% and 1.81t/h.m2 , respectively. Considering all the technical indexes, to gaining the best insight into the process of pelletizer sintering, the proportions of podwer and sludge should be controlled 100%, and size-distribution of pellerizer should be controlled from 5 to 10mm.
