MONITORING PARAMETERS OF COHESIVE ZONE IN BLAST-FURNACE

The thermoplastic properties of agglomerated concentrates have been de termined, and the influence of sinter and pellet chemical composition on blast furnace technical operating indices has been established. The results have been used to determine the spatial distribution of the c ohesive zone, the main factor in economical blast furnace operation, i n a 3200 m3 blast furnace. The influence of the zone parameters on gas flow distribution has been determined. A simplified method for monito ring the position of the cohesive zone is described, and the charging and operating conditions for a blast furnace of the given volume to pr oduce the most favourable cohesive zone are specified.
