METHOD FOR REGULATION OF HEAT STATE OF BLAST FURNACE

摘要

A method for regulation of heat state of blast furnace by the data of chemical composition of top gas and charge materials by change of blowing parameters. The influence on change of moisture or temperature of blowing is discretely formed in set time ranges by sign and value of deviation of sum composition [(CO + CO2) + 0.3H2] contained in top gas relative to its set optimal value the change of oxygen content in combined blowing and carbonates in charge.
