Resumo

The sinter testing results in standard test drum would depend to a large extent on the sampling place. The farther is this place from the sintering strand, the higher will be strength index for one and the same batch of sinter. This is accounted for by the fact that there is a dwindling of defects number in the sinter yield structure as it is being transported to the ironmaking shop. The determination of sampling place and methods are not unified at steel plants at all. Therefore, the methods of testing applied today cannot be used for comparative analysis of sinter characteristic made at various steel plants under different conditions in terms of production and raw material. In report a method is suggested for research and testing of sinter, based on a model which describes extensive desintegration of sinter. This method does not call for developing new designs of equipment or testing technique, it will be necessary only to modify the testing procedure and to use computers more widely.
