    Abstract: A direct smelting process for producing metals from a metalliferous feed material is disclosed. The process includes forming a molten bath having a metal layer (15) and a slag layer (16) on the metal layer in a metallurgical vessel, injecting metalliferous feed material and solid carbonaceous material into the metal layer via a plurality of lances/tuyeres (11), and smelting metalliferous material to metal in the metal layer. The process also includes causing molten material to be projected as splashes, droplets, and streams into a top space above a nominal quiescent surface of the molten bath to form a transition zone (23). The process also includes injecting an oxygen-containing gas into the vessel via one or more than one lance/tuyere (13) to post-combust reaction gases released from the molten bath, whereby the ascending and thereafter descending splashes, droplets and streams of molten material in the transition zone facilitate heat transfer to the molten bath, and whereby the transition zone minimises heat loss from the vessel via the side walls in contact with the transition zone. The process is characterised by controlling the process by maintaining a high slag inventory.

    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: Procedimiento de fusión directa para la producción de metales a partir de un material de carga metalífero que comprende las etapas siguientes: (a) la formación en una cuba metalúrgica de un baño fundido que presenta una capa de metal y una capa de escoria sobre la capa de metal; (b) la inyección de un material metalífero de carga y de un material carbonoso sólido en la capa de metal, mediante una pluralidad de lanzas/toberas dispuestas encima y que se extienden en sentido descendente hacia la capa de metal, y haciendo que el material fundido sea proyectado en forma de salpicaduras, pequeñas gotas y chorros a un espacio superior por encima de una superficie en reposo nominal del baño fundido para formar una zona de transición; (c) la fusión del material metalífero a metal en la capa de metal; y (d) la inyección de un gas que contiene oxígeno en la cuba mediante una o más de una lanza/tobera para realizar la postcombustión de los gases de reacción liberados por el baño fundido, con lo que lassalpicaduras, las pequeñas gotas y los chorros de material fundido ascendentes y a continuación descendentes en la zona de transición facilitan la transferencia de calor al baño fundido y con lo cual la zona de transición minimiza las pérdidas de calor de la cuba a través de las paredes laterales en contacto con la zona de transición; y cuyo procedimiento comprende la etapa de controlar el procedimiento manteniendo unas existencias de escoria elevadas controlando que la capa de escoria presente por lo menos 1, 5 metros de espesor.
