There are two types of reduction smelting of ferromanganese: flux method (also known as low manganese slag method) and flux-free method (high manganese slag method). The principle of the flux method is the same as that of blast furnace smelting, except that electric energy is used instead of coke for heating. By adding lime, a high alkalinity slag (CaO/SiO2 is 1.3~1.6) is formed to reduce the loss of manganese. Flux-free smelting without adding lime results in a low-iron, low-phosphorus and manganese-rich slag with low alkalinity (CaO/SiO2 less than 1.0) and high manganese content. This method has less slag, which can reduce power consumption, and the lower slag temperature can reduce the evaporation loss of manganese. At the same time, the by-product manganese-rich slag (containing 25~40% manganese) can be used as a raw material for smelting manganese-silicon alloys, achieving higher results. Comprehensive recovery rate of manganese (more than 90%)

Ferromanganese has a wide range of applications, mainly in the steelmaking and foundry industries.

Ferromanganese is usually used as a deoxidizer and desulfurizer. Good steel needs smelting deoxidation and desulfurization. Using a deoxidizer will greatly increase its cost, so ferromanganese is a cheap deoxidizer. Desulfurization refers to harmful substances such as steel sulfur. Ferromanganese can To achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel and improve the quality of steel.

Ferromanganese is a good accelerator and spheroidizing agent in casting. Adding ferromanganese during the casting process can effectively spheroidize graphite and greatly shorten the spheroidization time. On the other hand, high-carbon ferromanganese can also greatly reduce the shape of impurities in molten iron, improve the quality of cast iron, reduce clogging of the smelting furnace mouth, and effectively extend the service life of the smelting furnace.

1. High carbon ferromanganese is the cheapest, while low carbon ferromanganese is the most expensive.

2. High-carbon ferromanganese needs to increase carbon while increasing manganese. Therefore, when adding high carbon ferromanganese, be careful not to let the carbon get out of proportion. But when molten steel needs to supplement manganese and carbon at the same time, high-carbon ferromanganese becomes the best choice. Depending on the actual situation, use high carbon ferromanganese + medium carbon ferromanganese or high carbon ferromanganese + carbon wire (or carbon particles).

3. The amount of carbon added to medium-carbon ferromanganese is very small, so except for steel with very low carbon control, the issue of carbon added is basically not considered.
