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 method of starting a molten bath-based process for smelting a metalliferous material is disclosed. The method includes using the heat flux of water-cooled elements in lower parts of a smelting vessel to provide an indication of molten bath temperature during at least an early part of the start-up method and adjusting injection rates of oxygen-containing gas and/or carbonaceous material into the smelting vessel to control the molten bath temperature during start-up without exceeding critical heat flux levels and tripping the start-up method.
