COMPREHENSIVE REACTION BEHAVIOR OF A COKE MIXED BED UNDER BLAST FURNACE SIMULATED CONDITIONS WITH A CONSTANT LOAD

摘要

Nowadays, further efficiency and flexibility for blast furnace ironmaking process are required to save ferrous and fuel resources, utilize low quality materials and lower reducing agent rates together with conserving global environment. In this work, as one of these measures, comprehensive reaction behaviors of the packed bed consisting of both pellet (alternative to sinter) and metallurgical coke particles were examined in a laboratory reaction apparatus with flowing a reducing gas N2-CO-CO_2 under the blast furnace simulated conditions with a constant load until 1400°C, because these detailed reaction mechanisms are yet unknown.
