In order to make the large and medium-sized ferroalloy reduction electric furnace run better, it is required that the burden should have proper fragmentation and ensure good air permeability. At present, the supply of high-quality lumpy burdens which can be directly used in the furnace is becoming increasingly tight. In order to adapt to this situation, some manufacturers adopt various lumping technologies and use fine ore and concentrate to obtain better smelting indexes. Among them, high-pressure briquette machine pelletizing technology has become a new development direction of ferroalloy pelletizing technology in recent years because of its simple process, fuel-saving, applicability to fine ore, and a wide variety.
