Abstract: The disclosure relates to a direct smelting process that supplies a metalliferous material, a solid carbonaceous feed material and an oxygen-containing gas into a direct smelting vessel (Fig. 1) containing a molten bath of metal and slag to produce molten metal, molten slag and an off-gas. The process conditions are controlled such that the molten slag has a viscosity in a range of 0.5 – 5 poise at the operating temperature range for the process. The metalliferous material may be an iron-containing material such as iron ore, and the temperature range may be 1400 – 1550 degrees C.

Abstract: 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.

Abstract: A method of removing a blockage in a solids injection lance under normal operating conditions of a direct smelting vessel is disclosed. The direct smelting vessel contains a bath of molten metal and slag and the solids injection lance extends into the direct smelting vessel and has an outlet end that is submerged in the molten slag. The solids injection lance further has a single inlet coupled to a section of supply line that conveys gas and solid feed material to the solids injection lance. The method comprises (a) advancing a blockage-removing tool through the supply line section and through the solids injection lance to an upstream side of the blockage, (b) operating the tool under elevated gas pressure conditions to remove the blockage such that solid feed material and gas are able to flow through the solids injection lance. The method further comprises (c) retracting the tool from the solids injection lance and the supply line section. Also disclosed is an apparatus for removing a blockage in a solids injection lance extending into a direct smelting vessel.
