COLD START-UP METHOD FOR A DIRECT SMELTING PROCESS |
摘要 |
A method of cold starting a molten bath-based direct smelting process for producing molten iron in a vessel (3) is disclosed. The method includes a step of preheating the vessel before supplying solid feed materials into the vessel. The method also includes a subsequent step of supplying an oxygen-containing gas and solid feed materials including material for forming slag, iron-containing feed material, and carbonaceous material into the vessel and generating heat and forming a bath of molten material that includes molten iron and molten slag in the vessel. This step includes supplying feed materials to promote formation of molten slag over molten iron in an early stage of developing the molten bath
