Abstract

The sintering intensity is one of the important factors determining the technical and economic efficiency of sinter production which provides the blast-furnace process with the main kind of agglomerated raw iron ore. The process parameters of sintering critically influence the sinter burden caking rate. Therefore, the system study of the process parameters of sintering, which determine its intensity, is a matter of practical and scientific interest. In its purest form, it is shown that the sintering intensity is characterized by the vertical caking rate and the sinter burden carbon combustion intensity. The other two indices, including the specific performance for suitable sinter cake and the heat output intensity in the combustion zone, are less representative for the comparative estimation of the caking intensity, since their values depend on the sintered mass strength and the thermal effect of carbon combustion, respectively. These factors go beyond the essence of the sintering intensity concept. Since the content of 5 to 0 mm fines is different at different sinter plants, the representative comparison by sintering performance is possible only considering the total amount of returns at the sinter plant and the 5 to 0 mm fines generated along the whole sinter cake transport path to the blast furnace or the results of the sinter cake strength test in a drum. An integrated system classification of sintering intensification techniques is developed on the basis of the material-component principle using the separation into four levels which are objects, directions, paths, and methods. According to this principle, each subsequent level becomes more specific and develops the preceding one. The merit of this classification is its generality, which makes it possible to apply this system for classifying and separating almost all the already known and future methods of sintering intensification.
