Decision Support System for Controlling Thermal State of Blast Furnace Smelting

This article presents the results of studying the causes of the thermal instability of blast furnace smelting in nonstationary fuel-and-commodity and gas dynamic conditions when using PCI in air blasting and when injecting pulverized coal together with natural gas. The study results have allowed developing a decision support system for controlling the thermal state of blast furnace smelting in an adviser mode for process teams of blast furnace shops.
