Medium-carbon ferromanganese is a type of ferromanganese alloy divided by carbon content, which belongs to the metallurgical professional term published in 2019。 Its carbon content is between 0.7% and 2.0%, and it is mainly produced by electrosilicon thermal reduction method, shake bag method and oxygen blowing method, and the smelting process needs to cooperate with siliceous reducing agent and refining process 

The alloy undertakes the functions of deoxidizer, desulfurizer and alloy additives in the iron and steel industry, and is widely used in the smelting of special steel grades such as stainless steel and tool steel 

According to international production statistics, its consumption per ton of steel is maintained in the range of 0.7-1.0kg, and the production process often forms a joint production system with high-carbon ferromanganese and manganese-silicon alloys

Medium-carbon ferromanganese is a ferroalloy with manganese and iron as the main components, and according to the current metallurgical standards, it is divided into three categories according to the difference in carbon content: low-carbon type (≤0.7%), medium-carbon type (0.7%-2.0%) and high-carbon type (≥2.0%)。 This classification system is jointly adopted by major industrial countries in the world, among which Japan and the former Federal Republic of Germany have differences in technical parameters in the formulation of low- and medium-carbon ferromanganese standards
