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.

Abstract: A smelting apparatus that includes (a) a smelting vessel (4) that is adapted to contain a bath of molten metal and slag and (b) a smelt cyclone (2) for pre-treating a metalliferous feed material positioned above and communicating directly with the smelting vessel The apparatus also includes an oft-gas duct (9) extending from the smelt, cyclone for discharging an off-gas from the smelt cyclone. The off-gas duct has an inlet section (18) that extends upwardly from the smelt cyclone and is formed to cause off-gas to undergo a substantial change of direction as it flows through the inlet section of the off-gas duct.
