Abstract: Disclosed is a method of starting a molten-bath based melting process for smelting a metalliferous feed material in a smelting apparatus includes commencing supplying cold oxygen-containing gas and cold carbonaceous material into a main chamber of a smelting vessel within at most 3 hours after completing a hot metal charge into the vessel and igniting the carbonaceous material and heating the main chamber and molten metal in the main chamber. The apparatus includes a smelting vessel that includes a main chamber for containing a molten bath, a forehearth for discharging molten metal from the main chamber during a smelting campaign, and a forehearth connection that connects the main chamber and the forehearth. The method of starting a molten-bath based process includes the steps of (a) preheating the main chamber, the forehearth, and the forehearth connection and (b) pouring a charge of hot metal into the main chamber via the forehearth. The method includes (c) commencing supplying cold oxygen-containing gas and cold carbonaceous material into the main chamber within at most 3 hours after completing the hot metal charge and igniting the carbonaceous material and heating the main chamber and molten metal in the main chamber; then step (d) includes continuing supplying oxygen-containing gas and carbonaceous material into the main chamber and combusting carbonaceous material and heating the main chamber and molten metal in the main chamber for a period of at least 10 minutes; and (e) commencing feeding a metalliferous material into the main chamber in order to initiate metal production. The method includes verifying ignition of oxygen-containing gas and carbonaceous material in the main chamber.

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.

Abstract: A molten bath-based process for direct smelting metalliferous material and producing molten metal in a direct smelting vessel that contains a molten bath that has a metal layer that is at least 900 mm deep. The process includes selecting operating parameters of the process so that feed material (solid material and carrier gas) is injected from above the metal layer into the metal layer via at least one solids injection lance with sufficient momentum to penetrate to a depth of at least 100 mm below a nominal quiescent surface of the metal layer to cause upward movement of molten material and gas from the metal layer.

Abstract: A molten bath-based direct smelting process comprises controlling the process conditions in a direct smelting vessel so that molten slag in a molten bath of metal and slag in the vessel has a viscosity in a range of 0.5-5 poise when the slag temperature is in a range of 1400-1550°C in the molten bath in the vessel.
