Effect of Heating Condition on Carbothermic Reduction Behavior of Coal-Containing Composite Pellets Packed in Tall Bed

摘要

Blast Furnace is nowadays the most important ironmaking reactor because of its productivity and energy efficiency. However, blast furnace demands strict quality control of raw materials and results in environment issues. In the last decade, the high-grade iron ore and coking coal have become increasingly in short supply and costly. Meanwhile, the environmental regulations for the ironmaking process are getting stricter. Therefore, numerous non-blast furnace ironmaking processes have been developed in last 50 years, but with very limited success commercially [1]. The incentives to replace coke oven/sinter plant/blast furnace remain. Thus, the efforts towards this goal continue.
