The influence of quality of ferrous charge materials on the efficiency of blast furnace process

摘要

The assessment of influence of quality of ferrous charge materials on the efficiency parameters of blast furnace process is presented. The analysis of structure of ferrous charge materials was made. As a main quality parameter charge richness was selected. Then influence of charge richness on four parameters of efficiency 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 one calendar year.
