Abstract

The paper deals with a comparative analysis of reducibility of metallurgical sinter typical with high and low basicity. The samples were performed at 950°C of reduction test according to ISO 4695 which characterized their reducibility potential in CO atmosphere. Summing up the results, the differences in the testing of reduction processes were studied. The tests were accompanied with characterization of other properties such as density and apparent porosity to acquire comprehensive evaluation of the samples. All the data were used for interpretation and prediction of sample behavior in reduction processes in operation of the real blast furnace aggregate. Defining some processing parameters by mathematical model developed in Centre ENET, VSB – Technical University of Ostrava, financial costs for these samples processing were predicted on the basis of calculated coke reserve for the samples processing. Economical evaluation of processing of low and high basic sinter was carried out regarding the reduction gas consumption and costs estimation for metallurgical coke.
