The industrial experiment of direct alloying by manganite self-reducing briquettes was carried out in 100 t top botton combined converter

and the steel and slag were sampled and analyzed during smelting. The results show that the average yield of manganese is 65.17%

but it fluctuates greatly when the manganite ore self-reducing briquettes was added in the converter. Improving the end point of [C]

reducing the amount of slag and reducing the oxidation of slag can effectively improve the yield of manganese. When the adding amount of the briquettes was 15 kg/t

the average temperature drop 18 ℃.

and that will not affect the normal smelting of the converter.
