1. Ferromanganese is widely used in steel industry, foundry industry and other industrial production.2. 1. Iron and steel industry: Ferromanganese is an indispensable deoxidizer and desulfurizer in the steelmaking industry. Good steel needs deoxidation and desulfurization during smelting, and

Ferroalloys are various ferrous alloys that contain high proportions of one or more other elements such as manganese (Mn), aluminum (Al), or silicon (Si). [1] They are used in the production of steels and alloys. [2][3] These alloys impart unique qualities to steel and cast iron or play an important

The function of electric furnace steelmaking in the process is to process raw materials into molten steel with qualified composition and temperature at a certain rate.

Submerged arc furnace is a necessary equipment for smelting ferrosilicon, ferronickel, ferrochromium and calcium carbide in ferroalloy industry. According to incomplete statistics, there are more than 30000 submerged arc furnaces in China. For a long time, domestic submerged arc furnaces mostly use AC power supply, resulting in low power factor, difficult control and balance of three-phase power grid, low efficiency and high operation cost.
