Pressure control in direct melting process |
摘要 |
<p>A direct smelting process for producing molten iron and/or ferroalloys from a metalliferous feed material is disclosed. The process is a molten bath based process that is carried out in a direct smelting vessel. The process includes the steps of supplying metalliferous feed material, carbonaceous material and fluxes into the vessel; smelting metalliferous feed material to molten iron in the molten bath; and injecting an oxygen-containing gas into the vessel to post-combust gases generated in the process. The process is characterised by controlling the level of molten metal in the vessel by adjusting the pressure in the vessel. <IMAGE></p> |
