Abstract: A method of starting a molten-bath based melting process 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.

Abstract: A method of starting a molten-bath based melting process includes establishing a sufficiently large and stable "hot zone" by inserting an external ignition source for ignition of oxygen and coal in a main chamber of a smelting vessel by independent means, i.e. independently of and before supplying cold oxygen and coal into the main chamber.

Abstract: Disclosed is a method of starting a smelting process in a smelting vessel that includes a main chamber for smelting a metalliferous material and producing molten metal and a forehearth connected to the main smelting chamber via a forehearth connection. The smelting vessel contains frozen slag that blocks at least the forehearth connection. The method of starting the process includes heating frozen slag and forming molten slag and draining molten slag from the forehearth connection via the forehearth and establishing a clear flow path through the forehearth connection. Thereafter the smelting process is hot started by a series of steps including supplying a charge of molten metal into the main chamber via the forehearth connection and supplying feed materials to the process and smelting the metalliferous material and producing molten metal. The molten slag is removed via a forehearth end-drain taphole in a lowest region of the forehearth. The frozen slag in the forehearth connection is heated and melted via oxygen-enriched gas burners and/or oxygen lances. Where there is frozen slag in the main chamber, as well as frozen slag in the forehearth connection, the method includes heating and melting frozen slag in the main chamber and the forehearth connection. The frozen slag in the main chamber is heated and melted via heat from a burner system for the main chamber.
