Abstract

The assessment of quality of coke and its consumption in blast furnace process is presented in the paper. The statistical analysis of three basic parameters of coke was made. As a main quality parameters: moisture content, ash content in the dry state, volatile matter content in dry state and calorific value were selected. Then influence of two selected parameters of coke on fuel consumption was calculated. The study was carried out in cooperation with a Blast-Furnace Department of a Polish steelworks and was based on the results coming from this Department. The analysis covers the period of three calendar years.
