The international standard of high carbon ferromanganese is 75 ~ 80% manganese. In order to adapt to the raw material condition of low grade manganese ore, China has specified the brand with low manganese content (high carbon ferromanganese in electric furnace contains more than 65% manganese, and high carbon ferromanganese in blast furnace contains more than 50% manganese). Smelting carbon high carbon ferromanganese mainly used blast furnace in the past, with the development of electric power industry, the use of electric furnace gradually increased. Western Europe and China mainly use blast furnace, Norway, Japan use electric furnace, the Soviet Union, Australia, Brazil and other countries to build high-carbon ferromanganese factories also use electric furnaces.

High carbon ferromanganese is an iron alloy with iron and manganese as its main components. Used as deoxidizer, desulfurizer and alloying agent in steel work, the product is not only suitable for low carbon alloy structural steel, especially for high quality steel varieties, without changing the original steelmaking technology, can optimize the alloy, improve the internal quality of steel, reduce the cost of steelmaking alloy, has obvious economic benefits.
