The smelting reduction of manganese ore in the converter has been reported in China since the 1990s, and some steel enterprises have successively carried out industrial tests of this technology. However, the recovery ratio of Mn in manganese ore is low and fluctuates greatly due to various reasons such as inadequate hot-metal …
The size range of the manganese ore, coke, coal and limestone that was fed through the open-top of SAF, as shown in Figure 2, was 30-40 mm, 20-35 mm, 25-40 mm, and 20- 35 mm, respectively. Each trial smelting was carried out for 60 minutes, the current was 500 to 1000 A, and the pouring temperature was 1300°C to 1500°C.
From the viewpoint of an optimization the operating variables for energy efficiency of smelting reduction process, thermodynamic model for smelting reduction process of Manganese nodule was developed by using energy and material balance concept.
