Supplying solid feed materials for a direct smelting process

摘要

A direct smelting plant that includes an effective and reliable solids feed means for injecting solid feed materials, particularly carbonaceous material, into a direct smelting vessel of the plant is disclosed. The solid feed means is characterised by independent supply of carbonaceous material to injection lances. The independent supply of carbonaceous material minimises the possible adverse impact of a a breakdown of one or more than one lance or a breakdown of the carbonaceous material injection means for that lance or lances.
