Method of calculating and analyzing the factors that affect the coke consumption and productivity of blast furnaces at the Chelyabinsk Metallurgical Combine

Abstract

Statistical analysis is used to examine the effect of the main raw-material and process factors on coke rate and productivity for the blast furnaces at the Chelyabinsk Metallurgical Combine during the period from 2007 to July 2012. A method is developed for calculating and predicting coke rate and daily pig-iron output in the blast-furnace shop, and a combination of parameters is found to reduce coke rate and increase the productivity of the shop. The factors table which is used throughout the industry is refined for the conditions that exist in the blast-furnace shop at the ChMK.
