摘要： A process for direct smelting a metalliferous feed material containing at least 0.2 wt.% sulphur in a smelt cyclone and a direct smelting vessel containing a bath of molten metal is disclosed. The process is characterised by maintaining an oxygen potential in the smelt cyclone that is sufficient so that an offgas from the smelt cyclone has a post combustion degree of at least 75%.

摘要： A method for injecting a solid feed material through a solids injection lance includes creating flow conditions in an injection passageway of the lance so that at least a part of the feed material flowing along the passageway forms a buffer zone between a wall of a tube that defines the passageway and feed material flowing along a central section of the passageway.
