Abstract

Calculation-analytical investigation of composition and high temperature properties of charge materials and properties of primary and final slag from blowing-in burden during furnace shutdown is accomplished for JSC “ArselorMittal Kryvyy Rih” and JSC “Severstal” with the use of monitoring and control system of slag mode of blast-furnace smelting. The limiting values of physical and chemical properties of primary and final slag in the working mode, during blowing-in and blowing-out operations are determined.
