Research of Factors that Have a Significant Impact on the Energy Intensity of Blast Furnace Production
摘要
The purpose of the research is to identify factors that affect the energy intensity of blast furnace production, determination and provision of scientifically based recommendations on the use of the necessary equipment, which allows to reduce energy consumption in the existing technological paths. The identification of factors was identified by expert evaluation. The data obtained were processed statistically and ranked in descending order of influence on the energy intensity of the studied production. The degree of consistency of experts’ opinions was assessed using the concordance coefficient. According to the results of the expert assessment, it was found that the greatest impact on the energy intensity of blast furnace production is made by the content of substandard fractions of coke and the iron-containing part of the charge. Therefore, attention was paid to preparatory processes related to the separation of the metallurgical charge by size and the analysis of the formation of the particle size distribution of charge materials at different parts of the route of its processing and transportation to the blast furnace.
