    Abstract: A direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes a gas delivery duct assembly extending from a gas supply location away from the vessel to deliver oxygen-containing gas to gas injection lances extending into a direct smelting vessel. The gas delivery duct assembly includes a single gas delivery main connected to the gas injection lances to supply oxygen-containing gas to the gas injection lances. The gas delivery main is located at a height above a lower half of the vessel.

    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: Se revela una planta de fusión directa para producir metal fundido a partir de un material de alimentación metalífero. La planta incluye un convertidor de fusión fijo para alojar un bano fundido de metal y escoria y un espacio de gas por encima del bano. La planta también incluye elementos para suministrar materiales de alimentación de gas y sólidos al convertidor y para extraer material fundido del convertidor. La planta también incluye por lo menos dos plataformas paras soportar a los operarios de la planta a diferentes alturas del convertidor. Los elementos de extracción de metal y los elementos de extracción de escoria están ubicados de modo que sean accesibles para los operarios de la planta sobre una plataforma de la nave de colada y los elementos de extracción final de metal y los elementos de extracción final de escoria están ubicados de modo que sean accesibles para los operarios de la planta sobre una plataforma de extracción final que se encuentra a una altura mayor que la plataforma de la nave de colada.

    Abstract: A process for direct smelting a metalliferous feed material is disclosed. Char and fuel gas are produced by pre-treating coal with an oxygen-containing gas. The fuel gas is used to heat an oxygen-containing gas and/or to produce an oxygen-containing gas in an oxygen plant. Metalliferous feed material, char, and the oxygen-containing gas are injected into a direct smelting vessel, and the metalliferous feed material is smelted to molten metal in the direct smelting vessel using the char as a source of energy and as a reductant.
