select raw materials such as manganese ore, coke, limestone and other raw materials and pre-treat them; charge the furnace with proportional batching and mixing; melt the raw materials at high temperatures in electric arc furnaces or blast furnaces, and convert manganese oxides into manganese metal in a reducing environment to form alloys; adjust the alloy composition and desulfurize the alloys; separate the slag iron and cast the molten alloys; and after cooling, the alloys are subjected to a quality test to meet the standards. The process emphasizes energy efficiency and environmental protection, incorporating advanced technologies to reduce pollution and improve efficiency.
The ferromanganese smelting process is a production activity with high energy consumption and a certain impact on the environment. Therefore, the design and operation of modern ferromanganese smelting furnaces are increasingly focusing on energy saving and emission reduction, environmentally friendly technologies and recycling, such as the use of advanced combustion technologies, waste heat recovery systems, and dust collection and treatment devices, in order to minimize the impact on the environment and to improve production efficiency.
