| Abstract |
In hot metal, effects of temperature, basicity, and oxygen source on the reaction of desiliconization and demanganization were studied. The results are as follows; 1. The temperature of hot metal decreased slowly because of the reaction of desiliconization and demanganization. 2. Lower degree of desiliconization and demanganization was obtained at 1450℃ compared with 1350℃. 3. For the effective desiliconization and reducing Mn-loss, it was desirable that the basicity was about 1.0. 4. It was considered that the desiliconization treatment of hot metal should be conducted by mixture oxidizer (gas-solid) to reduce the Mn loss. |
