ALGORITHM FOR EVALUATING THE COMPOSITION AND DEGREE OF GRANULATION OF DIFFERENT SINTERING-MACHINE CHARGES

摘要

This articles examines methods of evaluating the degree of granulation of sintering-machine charges of various compositions. The literature contains 14 different criteria for making such an evaluation. The indices that have been proposed are analyzed and are shown to depend on the operating regime of cylindrical balling drums. It is established that the upper and lower coarseness limits for the charge and the length of time that granules close to the upper limit are heated need to be taken into account when choosing a method for evaluating degree of granulation.
